STRATEGIC REPORT
FOR THE YEAR ENDED 31 DECEMBER 2024

Introduction
 
The year ended 31 December 2024 marked a period of stability and strategic progress for the Company. We continued to build on our strong foundations, enhancing our operational capabilities and deepening our presence across both industrial and municipal water treatment markets.

A significant milestone this year was our achievement of B Corp Certification, reflecting our deep commitment to social and environmental performance, transparency, and accountability. This recognition reinforces our purpose-driven approach and aligns with our long-term sustainability goals.

Our Customer for Life strategy remains at the heart of our operations. By engaging early, we design and deliver optimal solutions using best-in-class technologies. We operate, maintain, and service our assets with a focus on continuous improvement and long-term value creation. This approach enables our customers to maximise the value of their water and wastewater resources, helping them close the water loop and meet their financial and sustainability objectives.

Achieving B Corp status has further shaped our strategic priorities by embedding sustainability, equity, and stakeholder engagement more deeply into our decision-making processes. It has strengthened our commitment to responsible growth, guided our innovation efforts toward more sustainable technologies, and reinforced our focus on creating long-term value not only for our customers and shareholders, but also for our employees, communities, and the environment.

These efforts have driven strong financial performance and strengthened long-term customer relationships, further solidifying our position as a trusted leader in the water treatment industry.

Business review
 
Principal risks and uncertainties
 
The Company’s principal risks and uncertainties primarily relate to health and safety, particularly due to the handling of hazardous chemicals and operations within industrial environments. We maintain stringent safety protocols, and we are pleased to report that no incidents occurred during the year.

Financial risks also remain a key consideration, particularly those associated with managing long-term projects, including revenue recognition and work-in-progress (WIP) accounting. These risks are actively managed through robust internal controls and close oversight from our parent company, Nijhuis Saur Industries.

While the Company has historically relied on a small number of key clients, we have made significant progress in diversifying our customer base, thereby reducing dependency on any single revenue stream. Ongoing regulatory compliance, particularly in light of evolving environmental standards, remains a strategic focus area.

Financial key performance indicators
 
The key performance indicators (KPIs) for the year reflect the Company’s strong financial health:                           
∙Revenues: 2024 revenue decreased to £46 million from £51 million.

∙Gross margin: The gross margin reduced from 2023, primarily driven by the cost of sales remaining in line with last year despite the reduction in revenue.

∙Cash flow: The Company maintained a healthy cash position, supported by the group’s cash pooling arrangements, ensuring continued financial stability.                                                                           
                                                                                                                                                                     
These indicators reflect the success of our operational strategy and our ability to deliver sustained growth.

DIRECTORS' REPORT
FOR THE YEAR ENDED 31 DECEMBER 2024

The directors present their report and the financial statements for the year ended 31 December 2024.

Directors

The directors who served during the year were:

M M Holterman (resigned 31 July 2026)
A Ruijtenberg (resigned 31 July 2026)
I M Stentiford 

Directors' responsibilities statement

The directors are responsible for preparing the Strategic report, the Directors' report and the financial statements in accordance with applicable law and regulations.
 
Company law requires the directors to prepare financial statements for each financial year. Under that law the directors have elected to prepare the financial statements in accordance with applicable law and United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice), including Financial Reporting Standard 102 ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland'. Under company law the directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the Company and of the profit or loss of the Company for that period.

 In preparing these financial statements, the directors are required to:


∙select suitable accounting policies for the Company's financial statements and then apply them consistently;

∙make judgements and accounting estimates that are reasonable and prudent;

∙state whether applicable UK Accounting Standards have been followed, subject to any material departures disclosed and explained in the financial statements;

∙prepare the financial statements on the going concern basis unless it is inappropriate to presume that the Company will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the Company's transactions and disclose with reasonable accuracy at any time the financial position of the Company and to enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the Company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

Principal activity

The principal activity of the company during the year was that of supplying waste water treatment and waste to
value for the industrial and municipal sectors and providing consultancy, design, construction and maintenance
services for water, waste and environmental engineering projects throughout the UK.

Results and dividends

The loss for the year, after taxation, amounted to £2,794,225 (2023 - profit £2,545,619).

DIRECTORS' REPORT (CONTINUED)
FOR THE YEAR ENDED 31 DECEMBER 2024


Greenhouse gas emissions, energy consumption and energy efficiency action

This report covers NSI Water & Wastewater Solutions Ltd, which is the reporting entity for SECR purposes and is responsible for including the required disclosures within its Directors Report. 

The reported energy consumption and greenhouse gas emissions have been determined using an operational control approach consistent with the Greenhouse Gas Protocol. Under this approach, emissions are reported for operations over which NSI Water & Wastewater Solutions Ltd has the authority to introduce and implement operating policies. This reporting boundary therefore includes activities undertaken by NSI Commercial Building Solutions Ltd, NSI Engineering Solutions Ltd, NSI Manufacturing UK Ltd and NSI Industrial O&M Solutions Ltd, which are managed and directed by NSI Water & Wastewater Solutions Ltd. 

This report therefore includes energy consumption and greenhouse gas emissions arising from operations over which the company has operational control during the reporting period.

Energy Consumption
The company’s total UK energy consumption during the reporting period was 3,503.93 MWh.

Energy Source                         Energy Consumption (MWh)
Purchased Electricity                                     463.32
Natural Gas                                                   485.78
Gas Oil                                                          14.80
Diesel                                                          1,816.52
Petrol                                                            375.52
Purchased Steam                                           347.99
Total Energy consumption                          3,503.93  

Greenhouse Gas Emissions
Greenhouse gas emissions have been calculated in accordance with the UK Government Environmental Reporting Guidelines and the UK Government greenhouse gas conversion factors 2024. Total Scope 1 and 2 greenhouse gas emissions for the reporting period were 1,171.30 tCO?e. The largest source of emissions were company vehicle fuel consumption and purchased energy.

Scope        Emission Source          Emissions (tCO2e)
Scope 1      Stationary Combustion   92.65
Scope 1      Mobile Combustion        508.47
Scope 1      Fugitive Emissions        1.62
Scope 2      Purchased Electricity    218.51
Scope 2      Purchased Steam         350.05

                                       
Emissions (tCO2e)
Total Scope 1                   602.74
Total Scope 2                   568.56
Total Scope 1 & Scope 2   1,171.30

Intensity Ratio
The company has selected tonnes of carbon dioxide equivalent per £ million turnover (tCO2e / £m turnover) as its primary intensity ratio. This metric has been selected because it provides a meaningful measure of greenhouse gas emissions relative to business activity and is appropriate for the nature of the company's operations. This intensity ratio allows year-on-year comparison of emissions performance while taking account of changes in business activity and revenue during the reporting period. Turnover for the reporting period was £68.16 million, resulting in an emissions intensity ratio of 17.185 per £ million turnover.

Metric                Unit                          Value
Intensity Ratio     tCO2e / £M turnover   17.185

DIRECTORS' REPORT (CONTINUED)
FOR THE YEAR ENDED 31 DECEMBER 2024

Energy Efficiency Actions
During the reporting period, the company undertook a number of initiatives aimed at reducing energy consumption and greenhouse gas emissions, including:
 
∙Ongoing monitoring of office energy consumption and established energy reduction targets across the business.
∙Ongoing monitoring and management of company vehicle fuel consumption to identify opportunities for efficiency improvements and establish fleet emissions baselines.
∙Development of carbon reporting processes to improve visibility of energy consumption and greenhouse gas emissions across the business.
∙Introduction of an Environmentally Preferable Purchasing Policy (EPP) to encourage the procurement of products and services with reduced environmental impact.
∙Completion of supplier sustainability surveys to improve understanding of environmental performance within the supply chain and support future emission reduction initiatives.
∙Expansion of carbon management activities, including commencing data collection for reporting year 2023 to produce a full carbon footprint assessment including scope 3 emissions.
∙In 2024, the parent company, Nijhuis Saur Industries UK & Ireland Ltd, became a certified B Corp, demonstrating high social and environmental performance across the UK group.
∙Launch of the WAVES sustainability engagement platform to promote employee awareness and  encourage sustainable behaviours across the organisation, including energy savings.
∙Presented our sustainability performance and carbon reduction strategy to all employees.

Methodology
Greenhouse gas emissions and energy consumption were calculated by Future Leap, a carbon consultancy, as part of the Nijhuis Saur Industries UK & Ireland 2024 Scope 1 and 2 carbon footprint assessment. This report included the following companies within the Nijhuis Saur Industries UK &Ireland Group: NSI Water & Wastewater Ltd, NSI Commercial Building Solutions Ltd, NSI Engineering Solutions Ltd, NSI Manufacturing UK Ltd and NSI Industrial O&M Solutions Ltd. The assessment was completed in accordance with the Greenhouse Gas Protocol Corporate Accounting and Reporting Standard and utilised the UK Government GHG Conversion Factors for Company Reporting 2024.

The reporting period covered 1 January 2024 to 31 December 2024. Scope 2 emissions were calculated using the location-based method. The carbon assessment was independently prepared and quality-reviewed by Future Leap and was based on available consumption data, including utility records, meter readings, fuel card data and equipment records. Where complete data was unavailable, reasonable estimation techniques were applied.

For the purpose of SECR reporting, the assessment was subsequently reviewed internally to align the reporting boundary with the activities under the operational control of NSI Water & Wastewater Ltd. The reporting boundary includes relevant activities undertaken by other NSI UK group entities where operational control is exercised by NSI Water & Wastewater Ltd. The original assessment also included emissions associated with client-owned water and wastewater treatment facilities operated under contract. These client-owned facilities have been excluded from the SECR disclosure as NSI Water & Wastewater does not own the assets, procure the energy, hold the environmental permits or have authority over capital investment decisions. The associated energy consumption and greenhouse gas emissions are therefore considered to fall within the reporting boundary of the asset owner in the case of SECR reporting in order to avoid double counting and to better reflect the reporting requirements of this scheme. For the purpose of SECR reporting, the carbon assessment was therefore reviewed internally and adjusted to reflect this reporting boundary. Emissions and energy consumption relating to the operation of client assets has therefore been excluded from this report. 

This disclosure therefore uses the Future Leap carbon assessment as its primary calculation methodology while applying internal adjustments to ensure the reported energy consumption and greenhouse gas emissions are representative of the activities of NSI Water & Wastewater.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF NSI WATER AND WASTEWATER SOLUTIONS LTD
 

Opinion


We have audited the financial statements of NSI Water and Wastewater Solutions Ltd (the 'Company') for the year ended 31 December 2024, which comprise the Statement of comprehensive income, the Statement of financial position, the Statement of changes in equity and the related notes, including a summary of significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland' (United Kingdom Generally Accepted Accounting Practice).


In our opinion the financial statements:


∙give a true and fair view of the state of the Company's affairs as at 31 December 2024 and of its loss for the year then ended;
∙have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and
∙have been prepared in accordance with the requirements of the Companies Act 2006.


Basis for opinion


We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditors' responsibilities for the audit of the financial statements section of our report. We are independent of the Company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the United Kingdom, including the Financial Reporting Council's Ethical Standard and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.


Conclusions relating to going concern


In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate.


Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.


Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.


Other information


The other information comprises the information included in the Annual Report other than the financial statements and our Auditors' report thereon. The directors are responsible for the other information contained within the Annual Report. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.


We have nothing to report in this regard.

Opinion on other matters prescribed by the Companies Act 2006
 

In our opinion, based on the work undertaken in the course of the audit:


∙the information given in the Strategic report and the Directors' report for the financial year for which the financial statements are prepared is consistent with the financial statements; and
∙the Strategic report and the Directors' report have been prepared in accordance with applicable legal requirements.


Matters on which we are required to report by exception
 

In the light of the knowledge and understanding of the Company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic report or the Directors' report.


We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:


∙adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or
∙the financial statements are not in agreement with the accounting records and returns; or
∙certain disclosures of directors' remuneration specified by law are not made; or
∙we have not received all the information and explanations we require for our audit.


Responsibilities of directors
 

As explained more fully in the Directors' responsibilities statement set out on page 3, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.


In preparing the financial statements, the directors are responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the Company or to cease operations, or have no realistic alternative but to do so.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF NSI WATER AND WASTEWATER SOLUTIONS LTD (CONTINUED)

Auditors' responsibilities for the audit of the financial statements
 

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an Auditors' report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.


Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance.

The risk is also greater regardig irregularities occurring due to fraud rather than error as fraud involves intentional concealment, foregery, collusion, omission or misrepresentation.

The specific procedures for this engagement that we designed and performed to detect material misstatements in respect of irregularities, including fraud, were as follows:
 
∙Enquiry of management and those charged with governance around actual and potential litigation and claims;
∙Enquiry of management and those charged with governance to identify any material instances of noncompliance with laws and regulations;
∙Reviewing financial statement disclosures and testing to supporting documentation to assess compliance with applicable laws and regulations;
∙Performing audit work to address the risk of irregularities due to management override of controls, including testing of journal entries and other adjustments for appropriateness, evaluating the business rationale of significant transactios outside the normal course of business and reviewing accounting estimates for evidence of bias.


A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our Auditors' report.


Use of our report
 

This report is made solely to the Company's members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the Company's members those matters we are required to state to them in an Auditors' report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company and the Company's members, as a body, for our audit work, for this report, or for the opinions we have formed.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

1.


General information

NSI Water and Wastewater Solutions Limited is a private company limited by shares and incorporated in England and Wales under the Companies Act 2006. The address of the registered office is Nanjerrick Court, Allet, Truro, Cornwall, TR4 9DJ.

2.Accounting policies

 
2.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with Financial Reporting Standard 102, the Financial Reporting Standard applicable in the UK and the Republic of Ireland and the Companies Act 2006.

The preparation of financial statements in compliance with FRS 102 requires the use of certain critical accounting estimates. It also requires management to exercise judgement in applying the Company's accounting policies (see note 3).

The following principal accounting policies have been applied:

 
2.2

Financial Reporting Standard 102 - reduced disclosure exemptions

The Company has taken advantage of the following disclosure exemptions in preparing these financial statements, as permitted by the FRS 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland":
∙the requirements of Section 7 Statement of Cash Flows;
∙the requirements of Section 3 Financial Statement Presentation paragraph 3.17(d);
∙the requirements of Section 11 Financial Instruments paragraphs 11.42, 11.44 to 11.45, 11.47, 11.48(a)(iii), 11.48(a)(iv), 11.48(b) and 11.48(c);
∙the requirements of Section 12 Other Financial Instruments paragraphs 12.26 to 12.27, 12.29(a), 12.29(b) and 12.29A;
∙the requirements of Section 26 Share-based Payment paragraphs 26.18(b), 26.19 to 26.21 and 26.23;
∙the requirements of Section 33 Related Party Disclosures paragraph 33.7.

This information is included in the consolidated financial statements of Holding D'Infrastructures des Metiers de L'Environnement as at 31 December 2024 and these financial statements may be obtained from 11 Cemin de Bretagne, 92130 Issy-Les-Moulineaux, France.

 
2.3

Going concern

The Directors anticipate that the Company will continue to operate as usual and that it can tolerate a reasonable level of unforeseen circumstances for a period of at least 12 months from the date of the financial statements. A group company, Saur SAS has issued a formal letter of support giving directors assurance that they will provide additional cash flow support if necessary for a period of at least one year from the date of the signed audit report. Based on this, the financial statements have been prepared on a going concern basis.

2.Accounting policies (continued)

 
2.4

Foreign currency translation

Functional and presentation currency

The Company's functional and presentational currency is GBP.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

Foreign exchange gains and losses resulting from the settlement of transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss except when deferred in other comprehensive income as qualifying cash flow hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the Statement of comprehensive income within 'finance income or costs'. All other foreign exchange gains and losses are presented in profit or loss within 'other operating income'.

 
2.5

Revenue

Revenue is recognised to the extent that it is probable that the economic benefits will flow to the Company and the revenue can be reliably measured. Revenue is measured as the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes. The following criteria must also be met before revenue is recognised:

Sale of goods

Revenue from the sale of goods is recognised when all of the following conditions are satisfied:
∙the Company has transferred the significant risks and rewards of ownership to the buyer;
∙the Company retains neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold;
∙the amount of revenue can be measured reliably;
∙it is probable that the Company will receive the consideration due under the transaction; and
∙the costs incurred or to be incurred in respect of the transaction can be measured reliably.

Rendering of services

Revenue from a contract to provide services is recognised in the period in which the services are provided in accordance with the stage of completion of the contract when all of the following conditions are satisfied:
∙the amount of revenue can be measured reliably;
∙it is probable that the Company will receive the consideration due under the contract;
∙the stage of completion of the contract at the end of the reporting period can be measured reliably; and
∙the costs incurred and the costs to complete the contract can be measured reliably.

2.Accounting policies (continued)

  
2.6

Long-term contracts

Profit on long term contracts is taken as the work is carried out if the final outcome can be assessed with reasonable certainty. The profit included is calculated on a prudent basis to reflect the proportion of the work carried out at the year end, by recording turnover and related costs as contract activity progresses.

Turnover is calculated as that proportion of total contract value which costs incurred to date bear to total expected costs for that contract. Revenues derived from variations on contracts are recognised only when they have been accepted by the customer. Full provision is made for losses on all contracts in the year in which they are first foreseen.

 
2.7

Operating leases: the Company as lessee

Rentals paid under operating leases are charged to profit or loss on a straight-line basis over the lease term.

 
2.8

Research and development

In the research phase of an internal project it is not possible to demonstrate that the project will generate future economic benefits and hence all expenditure on research shall be recognised as an expense when it is incurred. Intangible assets are recognised from the development phase of a project if and only if certain specific criteria are met in order to demonstrate the asset will generate probable future economic benefits and that its cost can be reliably measured. The capitalised development costs are subsequently amortised on a straight-line basis over their useful economic lives, which range from 3 to 6 years.

If it is not possible to distinguish between the research phase and the development phase of an internal project, the expenditure is treated as if it were all incurred in the research phase only.

 
2.9

Finance costs

Finance costs are charged to profit or loss over the term of the debt using the effective interest method so that the amount charged is at a constant rate on the carrying amount. Issue costs are initially recognised as a reduction in the proceeds of the associated capital instrument.

 
2.10

Pensions

Defined contribution pension plan

The Company operates a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. Once the contributions have been paid the Company has no further payment obligations.

The contributions are recognised as an expense in profit or loss when they fall due. Amounts not paid are shown in accruals as a liability in the Statement of financial position. The assets of the plan are held separately from the Company in independently administered funds.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2024

2.Accounting policies (continued)

 
2.11

Current and deferred taxation

The tax expense for the year comprises current and deferred tax. Tax is recognised in profit or loss except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the reporting date in the countries where the Company operates and generates income.

Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the reporting date, except that:
∙The recognition of deferred tax assets is limited to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits; and
∙Any deferred tax balances are reversed if and when all conditions for retaining associated tax allowances have been met.

Deferred tax balances are not recognised in respect of permanent differences except in respect of business combinations, when deferred tax is recognised on the differences between the fair values of assets acquired and the future tax deductions available for them and the differences between the fair values of liabilities acquired and the amount that will be assessed for tax. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by the reporting date.

Intangible assets

Goodwill

Goodwill represents the difference between amounts paid on the cost of a business combination and the acquirer’s interest in the fair value of its identifiable assets and liabilities of the acquiree at the date of acquisition. Subsequent to initial recognition, goodwill is measured at cost less accumulated amortisation and accumulated impairment losses. Goodwill is amortised on a straight-line basis to the Statement of comprehensive income over its useful economic life. Goodwill considered to have a finite useful life. If a reliable estimate of the useful life cannot be made, the useful life shall not exceed ten years.

Other intangible assets

Intangible assets are initially recognised at cost. After recognition, under the cost model, intangible assets are measured at cost less any accumulated amortisation and any accumulated impairment losses.

All intangible assets are considered to have a finite useful life. If a reliable estimate of the useful life cannot be made, the useful life shall not exceed ten years.

The estimated useful lives range as follows:

          Development costs                -        5 years    
          Computer Software                -        5 years

Intangible assets arising from development are capitalised based on the following conditions being met:

1. There is technical feasibility of completing the intangible asset so that it will be available for use or sale
2. The Company has the intention to complete the intangible asset and use or sell it 
3. The Company has the ability to use or sell the intangible asset
4. The Company can demonstrate that the asset will generate probable future economic benefits
5. The Company can demonstrate the availability adequate resources to complete the development and to use of sell the intangible asset
6. The expenditure attributable to the intangible asset can be measured reliably during its development.

2.Accounting policies (continued)

 
2.13

Tangible fixed assets

Tangible fixed assets under the cost model are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives, using the straight-line method.

Depreciation is provided on the following basis:

Short-term leasehold property
-
10%
straight-line
Plant and machinery
-
20%
straight-line
Motor vehicles
-
25%
straight-line
Fixtures and fittings
-
20%
straight-line
Other fixed assets
-
20%
straight-line

The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised in profit or loss.

 
2.14

Stocks

Stocks are stated at the lower of cost and net realisable value, being the estimated selling price less costs to complete and sell. Cost is based on the cost of purchase on a first in, first out basis. Work in progress and finished goods include labour and attributable overheads.

At each reporting date, stocks are assessed for impairment. If stock is impaired, the carrying amount is reduced to its selling price less costs to complete and sell. The impairment loss is recognised immediately in profit or loss.

 
2.15

Debtors

Short-term debtors are measured at transaction price, less any impairment. Loans receivable are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method, less any impairment.

 
2.16

Cash and cash equivalents

Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not more than 24 hours. Cash equivalents are highly liquid investments that mature in no more than three months from the date of acquisition and that are readily convertible to known amounts of cash with insignificant risk of change in value.

 
2.17

Creditors

Short-term creditors are measured at the transaction price. Other financial liabilities, including bank loans, are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method.

2.Accounting policies (continued)

 
2.18

Provisions for liabilities

Provisions are recognised when an event has taken place that gives rise to a legal or constructive obligation, a transfer of economic benefits is probable and a reliable estimate can be made.

Provisions are measured as the best estimate of the amount required to settle the obligation, taking into account the related risks and uncertainties.
 
Increases in provisions are generally charged as an expense to profit or loss.

 
2.19

Financial instruments

Basic financial assets

Basic financial assets, which include trade and other debtors, cash and bank balances, are initially measured at their transaction price (adjusted for transaction costs except in the initial measurement of financial assets that are subsequently measured at fair value through profit and loss) and are subsequently carried at their amortised cost using the effective interest method, less any provision for impairment, unless the arrangement constitutes a financing transaction, where the transaction is measured at the present value of the future receipts discounted at a market rate of interest.

Discounting is omitted where the effect of discounting is immaterial. The Company's cash and cash equivalents, trade and most other debtors due with the operating cycle fall into this category of financial instruments.

Basic financial liabilities

Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into. An equity instrument is any contract that evidences a residual interest in the assets of the Company after the deduction of all its liabilities.

Basic financial liabilities, which include trade and other creditors, bank loans and other loans are initially measured at their transaction price (adjusting for transaction costs except in the initial measurement of financial liabilities that are subsequently measured at fair value through profit and loss). When this constitutes a financing transaction, whereby the debt instrument is measured at the present value of the future payments discounted at a market rate of interest, discounting is omitted where the effect of discounting is immaterial.

Debt instruments are subsequently carried at their amortised cost using the effective interest rate method.

Trade creditors are obligations to pay for goods and services that have been acquired in the ordinary course of business from suppliers. Trade creditors are classified as current liabilities if the payment is due within one year. If not, they represent non-current liabilities. Trade creditors are initially recognised at their transaction price and subsequently are measured at amortised cost using the effective interest method. Discounting is omitted where the effect of discounting is immaterial.

Judgements in applying accounting policies and key sources of estimation uncertainty

The preparation of the financial statements requires management to make judgments, estimates and the assumptions that affect the amounts report for assets and liabilities as at the balance sheet date and the amounts reported for revenues and expenses during the year. However, the nature of the estimation means that actual outcomes could differ from those estimates. The following judgments (apart from those involving estimates) have had the most significant effect on amounts recognised in the financial statements.

Revenue and profits on contracts are recognised by reference to the proportion of work carried out and the contract value which involves management judgement. Consideration is also given to whether any costs incurred are not recoverable. 

Research and development expenditure
Expenditure on research and development is considered by the Directors in each reporting period for whether it qualifies as research or development expenditure in accordance with FRS 102. Judgement is required by the Directors for whether R&D costs qualify as development expenditure that should be capitalised as an intangible asset.
