STRATEGIC REPORT
FOR THE YEAR ENDED 30 APRIL 2025

Introduction
 
The directors present their strategic report for the year ended 30 April 2025. 

Business review
 
The company continues to lead the industry with innovative products in this highly technical and specialised field of thermal imaging and night vision. The directors are confident about the future. Thermoteknix commitment to innovation and commercial success has been widely recognized, including receiving the first-ever King's Award for Enterprise 2023 in International Trade and a second King's Award for Enterprise 2024 in Innovation, recognising Thermoteknix success in its Augmented Reality enhanced Night Vision and Thermal Imaging products. This marks the company's fifth such Royal award, following earlier "Queen's Award for Enterprise, Export" and two "Queen's Awards for Enterprise, Innovation". The company remains heavily invested in groundbreaking research and development across its industrial and imaging markets. This investment is entirely self-funded and based on both patented and patent-pending technologies. Significant contracts for specialist projects have been secured, with deliveries continuing in the next financial year. Global success has also been achieved with the recent launch of innovative new products in both the industrial and surveillance sectors. Increased global tension and activity in Eastern Europe have created new opportunities for Thermoteknix security and surveillance products, where the company's expertise is in high demand. The UK's decision to leave the European Union has introduced uncertainty for many businesses, resulting in fluctuations in currency exchange rates. Thermoteknix continues to assess the implications of limited access to European markets while seeking to capitalize on expanded global opportunities. The company takes well-considered measures to protect its foreign exchange exposure and maintain its status as a global exporter. The directors remain enthusiastic and confident about the company's future. Despite a reduction in turnover in the current year and substantial ongoing investment in R&D projects Thermoteknix has maintained positive cash flow, strong cash reserves, and a solid balance sheet. While it can take up to 24 months or more to transition a new product from launch to sale, especially in security market sectors, the company expects its current product range to significantly boost sales and profits in the coming years as these products establish themselves as market standards.

Principal risks and uncertainties
 
Market and economic risks 

Thermoteknix operates in a competitive market, where demand is partly dependent on the availability of funds to the ultimate end-users of its products. The company mitigates this risk by ensuring its products are technologically advanced through continuous investment in R&D and competitive pricing. High-quality, reliable, and innovative products are supported by excellent customer service and aftercare. Additionally, a well-trained and knowledgeable sales team is in place to build strong customer relationships. The global semiconductor shortage impacted product manufacturing and delivery times, as well as component purchase prices driven to unprecedented levels. The company continues to manage its component sourcing and manufacturing processes to meet expected orders and delivery schedules. 

Financial risks

The company mitigates its foreign exchange exposure by placing forward currency contracts when considered appropriate for committed and future purchases. Other financial risks are managed through regular management information systems and by monitoring prices and production requirements. 

Safety, health and environmental risks 

Safety, health, and environmental (SHE) risks are inherent in the business. Thermoteknix systematically assesses all SHE risks in accordance with UK legislation and industry best practices. The company is ISO 9001:2015 certified and remains committed to customer satisfaction, quality, and the health and safety of its staff.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF THERMOTEKNIX SYSTEMS LIMITED
 

Opinion


We have audited the financial statements of Thermoteknix Systems Limited (the 'Company') for the year ended 30 April 2025, which comprise the Statement of Comprehensive Income, the Balance Sheet, the Statement of Cash Flows, the Statement of Changes in Equity and the related notes, including a summary of significant accounting policiesThe 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 30 April 2025 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 ReportOur 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.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF THERMOTEKNIX SYSTEMS LIMITED (CONTINUED)


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 THERMOTEKNIX SYSTEMS LIMITED (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.


Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:

The objectives of our audit in respect of fraud, are; to identify and assess the risks of material misstatement of
the financial statements due to fraud; to obtain sufficient appropriate audit evidence regarding the assessed risks
of material misstatement due to fraud, through designing and implementing appropriate responses to those
assessed risks, and to respond appropriately to instances of fraud or suspected fraud identified during the audit.
However, the primary responsibility for the prevention and detection of fraud rests with both management and
those charged with governance of the company.

Our approach was as follows:

• We considered the nature of the commercial activities undertaken and the business performance for the year
and held discussions with management.
• We obtained an understanding of the legal and regulatory requirements applicable to the company and
considered that the most significant are the Companies Act 2006, UK financial reporting standards as issued by
the Financial Reporting Council, UK taxation legislation and Health and Safety.
• We obtained an understanding of how the company complies with these requirements by discussions with
management and those charged with governance.
• We assessed the risk of material misstatement of the financial statements, including the risk of material
misstatement due to fraud and how it might occur, by holding discussions with management and those charged
with governance.
• We inquired of management and those charged with governance as to any known instances of non-compliance
or suspected non-compliance with laws and regulations.
• We discussed during the audit engagement team briefing regarding how and where fraud might arise in the
financial statements and any potential indication of fraud. We remained alert to any indication of fraud or non-
compliance with laws and regulations throughout the audit.
• Based on this understanding, we designed specific appropriate audit procedures to identify instances of non-
compliance laws and regulations.

To address the risk of management override of controls, we carried out testing of journal entries and other adjustments for appropriateness, and evaluating the business rationale of significant transactions outside of the normal course of business. We also assessed management bias in relation to the accounting policies adopted in determining significant accounting estimates.

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 regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation. 


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.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 30 APRIL 2025

1.


General information

Thermoteknix Systems Limited is a private Company limited by shares incorporated in England and Wales. The registered office is Tennyson House, Cambridge Business Park, Cambridge, United Kingdom, CB4 0WZ.

The principal activity of the Company is the design, manufacture and sales of infrared camera and thermal imaging systems for security/surveillance, scientific, research & development, industrial and aerospace applications

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 judgment in applying the Company's accounting policies (see note 3).

The following principal accounting policies have been applied:

 
2.2

Going concern

In reaching the going concern conclusion the directors have considered the company's strong balance sheet position and the performance of the company in the current year and subsequent to the year end. 

The directors therefore believe the company continues to be a going concern and have prepared the financial statements on a going concern basis.

 
2.3

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'.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 30 APRIL 2025

2.Accounting policies (continued)

 
2.4

Revenue

Income represents revenue earned under a wide variety of contracts to provide hi-tech infrared equipment as well as after-sales services. 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. 

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 but in respect of goods made to order the income is recognised at the point of completion), 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.

 
2.5

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.

Benefits received and receivable as an incentive to sign an operating lease are recognised on a straight-line basis over the lease term, unless another systematic basis is representative of the time pattern of the lessee's benefit from the use of the leased asset.

 
2.6

Interest income

Interest income is recognised in profit or loss using the effective interest method.

 
2.7

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 Balance Sheet. The assets of the plan are held separately from the Company in independently administered funds.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 30 APRIL 2025

2.Accounting policies (continued)

 
2.8

Taxation

The tax expense for the current 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 balance sheet 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 balance sheet 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 balance sheet date.


 
2.9

Research and development costs

Research and development costs are written off fully in the period the expense is incurred. Items of equipment used in research and development activities are capitalised as fixed assets

 
2.10

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.

Depreciation is provided on the following basis:

Long-term leasehold property
-
Straight line over the period of lease
Plant and machinery
-
33%
Reducing balance
Motor vehicles
-
25%
Reducing balance
Fixtures and fittings
-
15%
Reducing balance

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.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 30 APRIL 2025

2.Accounting policies (continued)

 
2.11

Valuation of investments

Investments in subsidiaries are measured at cost less accumulated impairment.

 
2.12

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 balance sheet 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.

 
2.13

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.

 
2.14

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.

In the Statement of Cash Flows, cash and cash equivalents are shown net of bank overdrafts that are repayable on demand and form an integral part of the Company's cash management.

 
2.15

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.

 
2.16

Financial instruments

The Company has elected to apply the provisions of Section 11 “Basic Financial Instruments” 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 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.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 30 APRIL 2025

2.Accounting policies (continued)


2.16
Financial instruments (continued)


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.

Impairment of financial assets

At the end of each reporting period financial assets measured at amortised cost are assessed for objective evidence of impairment. 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. 

Financial assets are impaired when events, subsequent to their initial recognition, indicate the estimated future cash flows derived from the financial asset(s) have been adversely impacted. The impairment loss will be the difference between the current carrying amount and the present value of the future cash flows at the asset(s) original effective interest rate.

If there is a favourable change in relation to the events surrounding the impairment loss then the impairment can be reviewed for possible reversal. The reversal will not cause the current carrying amount to exceed the original carrying amount had the impairment not been recognised. The impairment reversal is recognised in the profit or loss.

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.

Other financial instruments

Derivatives, including forward exchange contracts, futures contracts and interest rate swaps, are not classified as basic financial instruments. These are initially recognised at fair value on the date the derivative contract is entered into, with costs being charged to the profit or loss. They are subsequently measured at fair value with changes in the profit or loss.

Debt instruments that do not meet the conditions as set out in FRS 102 paragraph 11.9 are subsequently measured at fair value through the profit or loss. This recognition and measurement would also apply to financial instruments where the performance is evaluated on a fair value basis as

with a documented risk management or investment strategy.

Derecognition of financial assets

Financial assets are derecognised when their contractual right to future cash flow expire, or are settled, or when the Company transfers the asset and substantially all the risks and rewards of ownership to another party. If significant risks and rewards of ownership are retained after the transfer to another party, then the Company will continue to recognise the value of the portion of the risks and rewards retained.


3.


Judgments in applying accounting policies 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  affects both current and future periods.

Stock Provisions
Determining stock provisions involves estimating the recoverable amount of stock held by the company.
Calculating the recoverable amount of stock requires a degree of estimation in terms of the likely
demand and prices for individual items.

Prior year adjustment

Previously a deferred tax asset was recognised in respect of accumulated taxable losses. It is unlikely and was unlikely that the deferred tax losses would be recovered or utilised. As a result a prior year adjustment amounting to £1,877,027 has been processed. The result of the adjustment reduced the profit in 2024 by £1,171,521 and reduced the opening reserves by £705,506.

Pension commitments

The Company operates a defined contributions pension scheme. The assets of the scheme are held separately from those of the Company  in an independently administered fund. The pension cost charge represents contributions payable by the Company  to the fund and amounted to £227,782 (2024 - £182,840). Contributions totaling £51,220 (2024 - £34,071) were payable to the fund at the balance sheet date and are included in creditors.
