Principal risks and uncertainties

The directors and senior management team comprises professionals who are experienced in both financial and operational management. They constantly monitor business risks and consider the key risks to be:

 

Market Competition

The market is highly competitive and there are constant price pressures placed on the products and services that the company provides. The directors and senior management team place continual focus and emphasis on the service provided to customers.

 

Financial Management

Profit risks are managed through the establishment of forecasts and preparation of monthly management accounts which monitor trends and key performance indicators relevant to each part of the business.

 

Credit Control

In common with other businesses of its size the company faces risks associated with current and future economic conditions and specifically how this affects our customer base. To address the company has strict credit control procedures to reduce the risk of bad debts to the company and has an active business development programme to attract new business to replace any lost through customers ceasing to trade.

Financial instruments

The company uses various instruments which include cash, trade debtors, and trade creditors which arise directly from its operations. The main risks arising from the financial instruments are cash flow, credit risk and liquidity risk. The directors review and agree policies for managing each of these risks and they are summarised below:

 

Cashflow risk

The business monitors cashflows on a constant basis, to ensure sufficient funds are in place to support business needs and ensure liabilities are met in accordance with agreed supplier terms.

 

Credit risk

Strict credit control procedures are in place for current and potential customers to keep the potential for bad debts to a minimum. Credit limits are set for customers based on a combination of payment history and third party credit references. These limits are reviewed by the credit control on a regular basis in conjunction with debt ageing and collection history and any issues are reported to a director.

 

Liquidity risk

The company seeks to manage financial risk by ensuring that sufficient liquidity is available to meet foreseeable needs.

Opinion

We have audited the financial statements of CTL Seal Limited (the 'company') for the year ended 31 March 2025 which comprise the statement of comprehensive income, the balance sheet, the statement of changes in equity, the statement of cash flows and notes to the financial statements, including 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:

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 Auditor's 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 UK, including the FRC’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 auditor's 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.

Opinions on other matters prescribed by the Companies Act 2006

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

INDEPENDENT AUDITOR'S REPORT
TO THE MEMBERS OF CTL SEAL LIMITED (CONTINUED)

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:

Responsibilities of directors

As explained more fully in the directors' responsibilities statement, 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.

Auditor's 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 auditor's 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.

Our approach to identifying and assessing the risks of material misstatement in respect of irregularities, including fraud and non-compliance with laws and regulations, was as follows:

 

We assessed the susceptibility of the company’s financial statements to material misstatement, including obtaining an understanding of how fraud might occur, by;

 

CTL SEAL LIMITED
INDEPENDENT AUDITOR'S REPORT
TO THE MEMBERS OF CTL SEAL LIMITED (CONTINUED)

To address the risks of fraud through management bias and override controls, we:

 

 

In response to the risk of irregularities and non-compliance with laws and regulations, we designed procedures which included, but were not limited to:

 

There are inherent limitations in our audit procedures described above. The more removed that laws and regulations are from financial transactions, the less likely it is that we would become aware of non-compliance. Auditing standards also limit the audit procedures required to identify non-compliance with laws and regulations to enquiry of the director’s and other management and the inspection of regulatory and legal correspondence.

As part of our audit, we addressed the risk of management override of internal controls, including testing of journals and review of the nominal ledger. We evaluated whether there was evidence of bias by the directors that represented a risk of material misstatement due to fraud.

A further description of our responsibilities is available on the Financial Reporting Council’s website at: https://www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor's 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 auditor's 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 MARCH 2025

1
Accounting policies
Company information

CTL Seal Limited is a private company limited by shares incorporated in England and Wales. The registered office is Butterthwaite Lane, Ecclesfield, Sheffield, South Yorkshire, United Kingdom, S35 9WA.

1.1
Accounting convention

These financial statements have been prepared in accordance with FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (“FRS 102”) and the requirements of the Companies Act 2006.

The financial statements are prepared in sterling, which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest £.

The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below.

1.2
Prior year restatement

Comparative amounts in relation to the cashflow statement have been restated to remove deferred grant income from the face of the statement, the restatement has no impact on net cashflows previously reported.

 

Comparative amounts in relation to debtors (Note 12) have been restated to show amounts owed by group undertakings that are due after more than one year. This has no impact on the profit or reserves previously reported.

1.3
Going concern

Atruet the time of approving the financial statements, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.

1.4
Turnover

Turnover is recognised at the fair value of the consideration received or receivable for goods and services provided in the normal course of business, and is shown net of VAT and other sales related taxes. The fair value of consideration takes into account trade discounts, settlement discounts and volume rebates.

 

When cash inflows are deferred and represent a financing arrangement, the fair value of the consideration is the present value of the future receipts. The difference between the fair value of the consideration and the nominal amount received is recognised as interest income.

Revenue from the sale of goods is recognised when the significant risks and rewards of ownership of the goods have passed to the buyer (usually on dispatch of the goods), the amount of revenue can be measured reliably, it is probable that the economic benefits associated with the transaction will flow to the entity and the costs incurred or to be incurred in respect of the transaction can be measured reliably.

Revenue from contracts for the provision of professional services is recognised by reference to the stage of completion when the stage of completion, costs incurred and costs to complete can be estimated reliably. The stage of completion is calculated by comparing costs incurred, mainly in relation to contractual hourly staff rates and materials, as a proportion of total costs. Where the outcome cannot be estimated reliably, revenue is recognised only to the extent of the expenses recognised that it is probable will be recovered.

1.5
Tangible fixed assets

Tangible fixed assets are initially measured at cost and subsequently measured at cost or valuation, net of depreciation and any impairment losses.

CTL SEAL LIMITED
NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)
FOR THE YEAR ENDED 31 MARCH 2025
1
Accounting policies
(Continued)
- 13 -

Depreciation is recognised so as to write off the cost or valuation of assets less their residual values over their useful lives on the following bases:

Short leasehold
10% straight line
Plant and equipment
5%-20% straight line
Fixtures and fittings
15% straight line
Computers
25% straight line
Motor vehicles
25% reducing balance

The gain or loss arising on the disposal of an asset is determined as the difference between the sale proceeds and the carrying value of the asset, and is credited or charged to profit or loss.

1.6
Impairment of fixed assets

At each reporting period end date, the company reviews the carrying amounts of its tangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where it is not possible to estimate the recoverable amount of an individual asset, the company estimates the recoverable amount of the cash-generating unit to which the asset belongs.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

 

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognised immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease.

Recognised impairment losses are reversed if, and only if, the reasons for the impairment loss have ceased to apply. Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognised immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the reversal of the impairment loss is treated as a revaluation increase.

1.7
Stocks

Stocks are stated at the lower of cost and estimated selling price less costs to complete and sell. Cost comprises direct materials and, where applicable, direct labour costs and those overheads that have been incurred in bringing the stocks to their present location and condition.

 

Stocks held for distribution at no or nominal consideration are measured at the lower of cost and replacement cost, adjusted where applicable for any loss of service potential.

At each reporting date, an assessment is made for impairment. Any excess of the carrying amount of stocks over its estimated selling price less costs to complete and sell is recognised as an impairment loss in profit or loss. Reversals of impairment losses are also recognised in profit or loss.

1.8
Long term contracts

Where the outcome of a long term contract can be estimated reliably, revenue and costs are recognised by reference to the stage of completion of the contract activity at the reporting end date. Variations in contract work, claims and incentive payments are included to the extent that the amount can be measured reliably and its receipt is considered probable.

 

When it is probable that total contract costs will exceed total contract turnover, the expected loss is recognised as an expense immediately.

 

Where the outcome of a long term contract cannot be estimated reliably, contract revenue is recognised to the extent of contract costs incurred where it is probable that they will be recoverable. Contract costs are recognised as expenses in the period in which they are incurred. When costs incurred in securing a contract are recognised as an expense in the period in which they are incurred, they are not included in contract costs if the contract is obtained in a subsequent period.

The “percentage of completion method” is used to determine the appropriate amount to recognise in a given period. The stage of completion is measured by the proportion of contract costs incurred for work performed to date compared to the estimated total contract costs. Costs incurred in the year in connection with future activity on a contract are excluded from contract costs in determining the stage of completion. These costs are presented as stocks, prepayments or other assets depending on their nature, and provided it is probable they will be recovered.

1.9
Cash and cash equivalents

Cash and cash equivalents are basic financial assets and include cash in hand, deposits held at call with banks, other short-term liquid investments with original maturities of three months or less, and bank overdrafts. Bank overdrafts are shown within borrowings in current liabilities.

1.10
Financial instruments

The company has elected to apply the provisions of Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instruments Issues’ of FRS 102 to all of its financial instruments.

 

Financial instruments are recognised in the company's balance sheet when the company becomes party to the contractual provisions of the instrument.

 

Financial assets and liabilities are offset, with the net amounts presented in the financial statements, when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

Basic financial assets

Basic financial assets, which include debtors and cash and bank balances, are initially measured at transaction price including transaction costs and are subsequently carried at amortised cost using the effective interest method 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. Financial assets classified as receivable within one year are not amortised.

Accounting policies
(Continued)
- 15 -
Impairment of financial assets

Financial assets, other than those held at fair value through profit and loss, are assessed for indicators of impairment at each reporting end date.

 

Financial assets are impaired where there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows have been affected. If an asset is impaired, the impairment loss is the difference between the carrying amount and the present value of the estimated cash flows discounted at the asset’s original effective interest rate. The impairment loss is recognised in profit or loss.

 

If there is a decrease in the impairment loss arising from an event occurring after the impairment was recognised, the impairment is reversed. The reversal is such that the current carrying amount does not exceed what the carrying amount would have been, had the impairment not previously been recognised. The impairment reversal is recognised in profit or loss.

Derecognition of financial assets

Financial assets are derecognised only when the contractual rights to the cash flows from the asset expire or are settled, or when the company transfers the financial asset and substantially all the risks and rewards of ownership to another entity, or if some significant risks and rewards of ownership are retained but control of the asset has transferred to another party that is able to sell the asset in its entirety to an unrelated third party.

Classification of 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 deducting all of its liabilities.

Basic financial liabilities

Basic financial liabilities, including creditors, are initially recognised at transaction price unless the arrangement constitutes a financing transaction, where the debt instrument is measured at the present value of the future payments discounted at a market rate of interest. Financial liabilities classified as payable within one year are not amortised.

 

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

 

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

Derecognition of financial liabilities

Financial liabilities are derecognised when the company’s contractual obligations expire or are discharged or cancelled.

1.11
Equity instruments

Equity instruments issued by the company are recorded at the proceeds received, net of transaction costs. Dividends payable on equity instruments are recognised as liabilities once they are no longer at the discretion of the company.

1.12
Taxation

The tax expense represents the sum of the tax currently payable and deferred tax.

CTL SEAL LIMITED
NOTES TO THE FINANCIAL STATEMENTS (CONTINUED)

Accounting policies
(Continued)
- 16 -
Current tax

The tax currently payable is based on taxable profit for the year. Taxable profit differs from net profit as reported in the profit and loss account because it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting end date.

Deferred tax

Deferred tax liabilities are generally recognised for all timing differences and deferred tax assets are recognised to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits. Such assets and liabilities are not recognised if the timing difference arises from goodwill or from the initial recognition of other assets and liabilities in a transaction that affects neither the tax profit nor the accounting profit.

1.13
Provisions

Provisions are recognised when the company has a legal or constructive present obligation as a result of a past event, it is probable that the company will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation.

 

The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the reporting end date, taking into account the risks and uncertainties surrounding the obligation. Where the effect of the time value of money is material, the amount expected to be required to settle the obligation is recognised at present value. When a provision is measured at present value, the unwinding of the discount is recognised as a finance cost in profit or loss in the period in which it arises.

1.14
Employee benefits

The costs of short-term employee benefits are recognised as a liability and an expense, unless those costs are required to be recognised as part of the cost of stock or fixed assets.

 

The cost of any unused holiday entitlement is recognised in the period in which the employee’s services are received.

 

Termination benefits are recognised immediately as an expense when the company is demonstrably committed to terminate the employment of an employee or to provide termination benefits.

1.15
Retirement benefits

Payments to defined contribution retirement benefit schemes are charged as an expense as they fall due.

1.16
Leases

Rentals payable under operating leases, including any lease incentives received, are charged to profit or loss on a straight line basis over the term of the relevant lease except where another more systematic basis is more representative of the time pattern in which economic benefits from the leases asset are consumed.

1.17
Government grants

Government grants are recognised at the fair value of the asset received or receivable when there is reasonable assurance that the grant conditions will be met and the grants will be received.

 

A grant that specifies performance conditions is recognised in income when the performance conditions are met. Where a grant does not specify performance conditions it is recognised in income when the proceeds are received or receivable. A grant received before the recognition criteria are satisfied is recognised as a liability.

Judgements and key sources of estimation uncertainty

In the application of the company’s accounting policies, the directors are required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

 

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

Key sources of estimation uncertainty

The estimates and assumptions which have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities are as follows.

After-sale service provision

Management has exercised judgement in determining whether a present obligation exists under after-sales service arrangements and whether it is probable that an outflow of resources will be required to settle such obligations. The provision for after-sales service is based on historical service data and expected future costs to fulfil these commitments. Actual outcomes may differ from these estimates due to variations in failure rates, repair requirements, or replacement costs.

Long term contracts

Turnover is generated from long term contracts. The company recognises contract revenue and contract costs associated with each contract using the stage of completion method. The recognition of revenue and profit therefore rely on estimates in relation to the stage of completion and the forecast total costs of each contract. At the year-end, the progress of each ongoing contract is reviewed and total costs to complete are assessed. Based on this margin is recognised in the profit and loss account to reflect the stage of completion.

 

The method applies ensures that profit is recognised equally across the life of the project. The calculation of expected outturn is based on the following factors:

 

 

The degree of estimation uncertainty centers around the expected costs to complete the contract which, combined with the contract turnover, are used to calculate the expected margin outturn on each project.

 

When contract losses are anticipated these are recognised in full at the time of identification insofar as they can be measured reliably.
