STRATEGIC REPORT

Introduction
 
The directors present their strategic report for the year ended 30 September 2024.

Strategic review
 
The company was incorporated on 3 October 2019 and acts as an intermediate holding company of a group of companies. The purpose of the company is to coordinate certain services shared between members of the UK group. These accounts present the results of this holding company only. The only activity in the year related to bank charges, interest, foreign exchange losses and dividends received from the company's subsidiaries. 

Future developments
 
The services offered by the company will be developed and expanded in line with the needs of the group.
Financial risk management objectives and policies
The directors consider that there is limited exposure to financial risk as the majority of the Company’s financial
exposure is to other Companies in the Tetra Tech Inc. group. The Company’s financial risk management objectives and policies are aligned to those of the Tetra Tech Inc. group of companies which are disclosed in the consolidated financial statements of the Company’s ultimate holding Company, Tetra Tech Inc.
Corporate Social Responsibility 
As a responsible corporate citizen, the group is committed to the highest standards of ethics, integrity and compliance in all respects of our business.  The group's corporate social responsibility practices are aligned to those of Tetra Tech, Inc. and the most recent Sustainability Report Card is publicly available at www.tetratech.com.
Section 172 (1) Statement
Section 172 of the Companies Act 2006 requires each Director of the Company to act in the way he or she considers would be most likely to promote the success of the Company for the benefit of its members as a whole. In doing this, Section 172 requires a Director to have regard to: the likely consequences of any decision in the long term; the interests of the Company's employees; the need to foster the Company's business relationships with customers, suppliers, and others; the impact of the Company's operations on the community and environment; the desirability of the Company maintaining a reputation for high standards of business conduct; and the need to act fairly with members of the Company.
 
The Directors give careful consideration to the factors set out above in discharging their duties under Section 172. The stakeholders considered in this regard are the people who work for the Company, its subsidiaries, and their clients who require us to implement programs in Africa; the Middle-East; Asia; and Europe. The Directors recognise that building strong relationships with our stakeholders will help the Company deliver its strategy in line with its long-term values and operate the business in a sustainable way.
The Directors of the Company seek to understand the interests and views of the Company's stakeholders by engaging with them directly as appropriate. Some of the ways in which the Directors engaged directly with the stakeholders over the year are detailed below:

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF TETRA TECH UK LIMITED
 

Opinion


We have audited the financial statements of Tetra Tech UK Limited (the 'Company') for the year ended 30 September 2024, which comprise the Statement of comprehensive income, the Balance sheet, 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 September 2024 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 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 TETRA TECH UK 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 TETRA TECH UK 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.

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.
 
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 non-compliance 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 transactions 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 2006Our 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.

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.

 
2.9

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.

 
2.10

Financial instruments

The Company only enters into basic financial instrument transactions that result in the recognition of financial assets and liabilities like trade and other debtors and creditors, loans from banks and other third parties, loans to related parties and investments in ordinary shares.
Debt instruments (other than those wholly repayable or receivable within one year), including loans and other accounts receivable and payable, are initially measured at present value of the future cash flows and subsequently at amortised cost using the effective interest method. Debt instruments that are payable or receivable within one year, typically trade debtors and creditors, are measured, initially and subsequently, at the undiscounted amount of the cash or other consideration expected to be paid or received. However, if the arrangements of a short-term instrument constitute a financing transaction, like the payment of a trade debt deferred beyond normal business terms or in case of an out-right short-term loan that is not at market rate, the financial asset or liability is measured, initially at the present value of future cash flows discounted at a market rate of interest for a similar debt instrument and subsequently at amortised cost, unless it qualifies as a loan from a director in the case of a small company, or a public benefit entity concessionary loan.

Judgements in applying accounting policies and key sources of estimation uncertainty

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 underlying assumptions are reviewed on an ongoing basis. During the year there were no critical accounting judgements made by the directors.
Key sources of estimation uncertainty
Impairment of fixed asset investments
The Directors deemed it necessary to determine whether there are indicators of impairment of the Company’s fixed asset investments. Factors taken into consideration in reaching such a decision include the economic viability and expected future financial performance of the asset. No impairment provision has been recognised as a consequence of this review as at 30 September 2024.
