Calibrate Group Limited

Statement of Directors' Responsibilities

The directors acknowledge their responsibilities for preparing the Annual 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 United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law). 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 and apply them consistently;

make judgements and accounting estimates that are reasonable and prudent;

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 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.

 

Calibrate Group Limited

Independent Auditor's Report to the Members of Calibrate Group Limited

Opinion

We have audited the financial statements of Calibrate Group Limited (the 'company') for the year ended 31 March 2025, which comprise the Profit and Loss Account, Balance Sheet, Statement of Changes in Equity, and Notes to the Financial Statements, 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 FRS 102 Section 1A '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 March 2025 and of its profit 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 auditor 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.

Emphasis of matter

We draw attention to note 2 to the financial statements which explains that the directors intend to liquidate the company and therefore do not consider it to be appropriate to adopt the going concern basis of accounting in preparing the financial statements. Accordingly, the financial statements have been prepared on a basis other than going concern as described in note 2. Our opinion is not modified in respect of this matter.

Other information

The directors are responsible for the other information. The other information comprises the information included in the annual report, other than the financial statements and our auditor’s report thereon. 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.

In connection with our audit of the financial statements, 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 audit or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether there is a material misstatement in the financial statements or a material misstatement of the other information. 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.

 

Calibrate Group Limited

Independent Auditor's Report to the Members of Calibrate Group Limited

Opinion on other matter 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 Directors' Report for the financial year for which the financial statements are prepared is consistent with the financial statements; and

the Directors' Report has been prepared in accordance with applicable legal requirements.

Matters on which we are required to report by exception

In the light of our knowledge and understanding of the company and its environment obtained in the course of the audit, we have not identified material misstatements in the Directors' Report.

We have nothing to report in respect of the following matters where 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; or

the directors were not entitled to prepare the financial statements in accordance with the small companies regime and take advantage of the small companies’ exemptions in preparing the directors’ report and from the requirement to prepare a strategic report.

Responsibilities of directors

As explained more fully in the Statement of Directors' Responsibilities [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.

Auditor 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.

The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:

 

Calibrate Group Limited

Independent Auditor's Report to the Members of Calibrate Group Limited

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:

- the engagement partner ensured that the engagement team collectively had the appropriate competence, capabilities and skills to identify or recognise non-compliance with applicable laws and regulations;
- we identified the laws and regulations applicable to the company through discussions with directors and other management, and from our cumulative audit and commercial knowledge and experience of the company and the sector;
- we focused on specific laws and regulations which we considered may have a direct material effect on the financial statements or the operations of the company, including the Companies Act 2006, Taxation Legislation, General Data Protection Rules (GDPR), Anti-Bribery Act, Employment Law and Health & Safety legislation;
- we assessed the extent of compliance with the laws and regulations identified above through making enquiries of management and inspecting legal correspondence; and
- identified laws and regulations were communicated within the audit team regularly and the team remained alert to instances of non-compliance throughout the audit.

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

- making enquiries of management as to where they considered there was susceptibility to fraud, their knowledge of actual, suspected, and alleged fraud; and
- considering the internal controls in place to mitigate risks of fraud and non-compliance with laws and regulations.

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

- performed analytical procedures to identify any unusual or unexpected relationships;
- tested journal entries to identify unusual transactions; and
- investigated the rationale behind significant or unusual transactions.

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

- agreeing financial statement disclosures to underlying supporting documentation;
- enquiring of management as to actual and potential litigation and claims; and
- reviewing correspondence with HMRC and analysing legal costs to ascertain if there have been instances of non-compliance with laws and regulations.

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 is available on the Financial Reporting Council’s website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.

 

Calibrate Group Limited

Independent Auditor's Report to the Members of Calibrate Group Limited

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.

These financial statements were authorised for issue by the Board on 17 October 2025.

Accounting policies

Summary of significant accounting policies and key accounting estimates

The principal accounting policies applied in the preparation of these financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

Statement of compliance

These financial statements have been prepared in accordance with Financial Reporting Standard 102 Section 1A smaller entities - 'The Financial Reporting Standard applicable in the United Kingdom and Republic of Ireland' and the Companies Act 2006 (as applicable to companies subject to the small companies' regime).

Basis of preparation

These financial statements have been prepared using the historical cost convention except that as disclosed in the accounting policies certain items are shown at fair value.

The financial statements are presented in sterling, which is the functional currency of the company.

As permitted by the FRS 102 1A framework, the company has taken advantage of the disclosure exemptions available under that standard in relation to presentation of a cashflow statement, remuneration of key management personnel and presentation of changes in current tax and deferred tax assets/liabilities.

These accounts are consolidated into the accounts of RSK Group Ltd.

Going concern

These financial statements have been prepared on a non-going concern basis. The directors have concluded that it is not appropriate to adopt the going concern basis of accounting, as the company is no longer trading and the directors have planned to apply for the company’s dissolution in the near future.

Revenue recognition

Turnover comprises the fair value of the consideration received or receivable for the provision of services in the ordinary course of the Company's activities. Turnover is shown net of sales/value added tax, returns, rebates and discounts and after eliminating sales within the company.

 

Calibrate Group Limited

Notes to the Financial Statements for the Year Ended 31 March 2025

Business combinations

Business combinations are accounted for using the purchase method. The consideration for each acquisition is measured at the aggregate of the fair values at acquisition date of assets given, liabilities incurred or assumed, and equity instruments issued by the group in exchange for control of the acquired, plus any costs directly attributable to the business combination. When a business combination agreement provides for an adjustment to the cost of the combination contingent on future events, the group includes the estimated amount of that adjustment in the cost of the combination at the acquisition date if the adjustment is probable and can be measured reliably.

Investments

Investments in equity shares which are publicly traded or where the fair value can be measured reliably are initially measured at fair value, with changes in fair value recognised in profit or loss. Investments in equity shares which are not publicly traded and where fair value cannot be measured reliably are measured at cost less impairment.

Interest income on debt securities, where applicable, is recognised in income using the effective interest method. Dividends on equity securities are recognised in income when receivable.

Debtors

Short-term debtors are measured at transaction price, less any impairment.

Creditors

Creditors are recognised initially at fair value and subsequently measured at amortised cost using the effective interest rate method.

Share capital

Ordinary shares are classified as equity. Equity instruments are measured at the fair value of the cash or other resources received or receivable, net of the direct costs of issuing the equity instruments. If payment is deferred and the time value of money is material, the initial measurement is on a present value basis.

Defined contribution pension obligation

A defined contribution plan is a pension plan under which fixed contributions are paid into a pension fund and the company has no legal or constructive obligation to pay further contributions even if the fund does not hold sufficient assets to pay all employees the benefits relating to employee service in the current and prior periods.

Contributions to defined contribution plans are recognised as employee benefit expense when they are due. If contribution payments exceed the contribution due for service, the excess is recognised as a prepayment.

 

Calibrate Group Limited

Notes to the Financial Statements for the Year Ended 31 March 2025

Financial instruments

Financial assets and liabilities are recognised in the company’s balance sheet when the company becomes party to the contractual provisions of the instrument.

Financial assets
Basic financial assets, including trade and other receivables, loans receivable from other Group companies, investments in subsidiary companies and cash and cash equivalents, are initially recognised at transaction price, unless the arrangement constitutes a financing transaction, where the transaction is measured at the present value of future receipts discounted at the market rate of interest. Such assets are subsequently carried at amortised cost using the effective interest method, less any provision for impairment.

Impairment of financial assets
At each reporting date the company assesses whether there is objective evidence that a financial asset is impaired. If such evidence exists, the company recognises an impairment loss which is measured as the difference between the carrying amount and the present value of the future cashflows, discounted at the original effective interest rate. Impairment losses are recognised in profit or loss.

Impairment losses are reversed if the reversal can be objectively related to an event occurring after the impairment was recognised. The reversal of the impairment will be recognised in profit or loss.

Financial liabilities
Basic financial liabilities, including trade and other payables, bank loans, hire purchase contracts and loans payable to other Group companies, are initially recognised at transaction price, unless the arrangement constitutes a financing transaction, where the debt instrument is measured at the present value of future payments discounted at the market rate of interest.

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

Derecognition of financial instruments
A financial asset is derecognised when the contractual rights to the cash flows from the financial asset expire, or the company transfers the financial asset and substantially all the risks and rewards of ownership have been transferred.

A financial liability is derecognised when the obligation specified in the contract is discharged, cancelled, or expires.
