| Report of the Directors |
| for the Year Ended 31 December 2025 |
| The directors present their report with the financial statements of the company for the year ended 31 December 2025. |
| PRINCIPAL ACTIVITY |
| The principal activity of the company in the year under review was that of water, wastewater and air treatment design, process and project management. |
| DIRECTORS |
| Other changes in directors holding office are as follows: |
| STATEMENT OF DIRECTORS' RESPONSIBILITIES |
| The directors are responsible for preparing the Report of the Directors 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 then 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. |
| STATEMENT AS TO DISCLOSURE OF INFORMATION TO AUDITORS |
| So far as the directors are aware, there is no relevant audit information (as defined by Section 418 of the Companies Act 2006) of which the company's auditors are unaware, and each director has taken all the steps that he or she ought to have taken as a director in order to make himself or herself aware of any relevant audit information and to establish that the company's auditors are aware of that information. |
| AUDITORS |
| The auditors, Roedl & Partner Ltd, will be proposed for re-appointment at the forthcoming Annual General Meeting. |
| Aquabio Limited (Registered number: 03379754) |
| Report of the Directors |
| for the Year Ended 31 December 2025 |
| This report has been prepared in accordance with the provisions of Part 15 of the Companies Act 2006 relating to small companies. |
| ON BEHALF OF THE BOARD: |
| Report of the Independent Auditors to the Members of |
| Aquabio Limited |
| Opinion |
| We have audited the financial statements of Aquabio Limited (the 'company') for the year ended 31 December 2025 which comprise the Income Statement, 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 Financial Reporting Standard 102 'The Financial Reporting Standard applicable in the UK and Republic of Ireland' (United Kingdom Generally Accepted Accounting Practice). |
| In our opinion the financial statements: |
| - | give a true and fair view of the state of the company's affairs as at 31 December 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 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 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. |
| Report of the Independent Auditors to the Members of |
| Aquabio Limited |
| Other information |
| The directors are responsible for the other information. The other information comprises the information in the Report of the Directors, but does not include the financial statements and our Report of the Auditors 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 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 the audit: |
| - | the information given in the Report of the Directors for the financial year for which the financial statements are prepared is consistent with the financial statements; and |
| - | the Report of the Directors has 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 Report of the Directors. |
| 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' exemption from the requirement to prepare a Strategic Report or in preparing the Report of the Directors. |
| Responsibilities of directors |
| As explained more fully in the Statement of Directors' Responsibilities set out on page two, 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 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. |
| Report of the Independent Auditors to the Members of |
| Aquabio Limited |
| 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 a Report of the Auditors 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: |
| - Enquiry of management, those charged with governance around actual and potential litigation and claims; |
| - Enquiry of entity staff to identify any 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 over the risk of 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 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 Report of the Auditors. |
| 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 a Report of the Auditors 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. |

| 2. | ACCOUNTING POLICIES - continued |
| Turnover |
| Turnover represents net invoiced sales of goods, excluding value added tax, except in respect of long-term construction or service contracts. |
| When the outcome of a long-term construction contract can be estimated reliably, contract revenue and contract costs are recognised as revenue and expenses respectively by reference to the stage of completion of the contract activity at the balance sheet date ("percentage-of-completion method"). When the outcome of a construction contract cannot be estimated reliably, contract revenue is recognised to the extent of contract costs incurred that are likely to be recoverable. When it is probable that total contract costs will exceed total contract revenue, the expected loss is recognised as an expense immediately. |
| Contract revenue comprises the initial amount of revenue agreed in the contract and variations in the contract work and claims that can be measured reliably. A variation or a claim is recognised as contract revenue when it is probable that the customer will approve the variation or negotiations have reached an advanced stage such that it is probable that the customer will accept the claim. |
| Cost includes all direct expenditure and an appropriate proportion of fixed and variable overheads. |
| At the date of authorisation of these financial statements, the following amendments to FRS 102 have been issued but are not yet effective for the current reporting period. |
| The Financial Reporting Council has issued amendments to FRS 102 which include significant changes to lease accounting, bringing lessee accounting more in line with IFRS 16. Under the revised requirements, lessees will be required to recognise a right?of?use asset and a corresponding lease liability for most leases. |
| These amendments are effective for accounting periods beginning on or after 1 January 2026, with early adoption permitted. |
| The entity has not early adopted these amendments. The directors are currently assessing the impact of these changes on the financial statements. It is expected that the adoption of the revised lease accounting requirements will result in an increase in both assets and liabilities on the balance sheet; however, the financial impact has not yet been reasonably estimated. |

| Development expenditure |
| Development expenditure is capitalised in accordance with the accounting policy given below. Initial capitalisation of costs is based on management's judgement that technical and economic feasibility is confirmed. In determining the amounts to be capitalised management makes assumptions regarding the expected future cash generation of the assets, and the expected period of benefits. Development expenditure is amortised on a straight-line basis over its useful economic life up to a presumed maximum of 5 years. It is reviewed for impairment if events or changes in circumstances indicate that the carrying value may not be recoverable. |
| Tangible fixed assets |
| Plant and machinery | - |
| Fixtures and fittings | - |
| Motor vehicles | - |
| Computer equipment | - |
| Stocks |
| Stocks and work in progress are valued at the lower of cost and net realisable value, after making due allowance for obsolete and slow moving items. |
| Taxation |
| Taxation for the year comprises current and deferred tax. Tax is recognised in the Income Statement, except to the extent that it relates to items recognised in other comprehensive income or directly in equity. |
| Current or deferred taxation assets and liabilities are not discounted. |
| Current tax is recognised at the amount of tax payable using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date. |
| Deferred tax |
| Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the balance sheet date. |
| Timing differences arise from the inclusion of income and expenses in tax assessments in periods different from those in which they are recognised in financial statements. Deferred tax is measured using tax rates and laws that have been enacted or substantively enacted by the year end and that are expected to apply to the reversal of the timing difference. |
| Unrelieved tax losses and other deferred tax assets are recognised only to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits. |

| Foreign currencies |
| Assets and liabilities in foreign currencies are translated into sterling at the rates of exchange ruling at the balance sheet date. Transactions in foreign currencies are translated into sterling at the rate of exchange ruling at the date of transaction. Exchange differences are taken into account in arriving at the operating result. |
| Pension costs and other post-retirement benefits |
| The company operates a defined contribution pension scheme. Contributions payable to the company's pension scheme are charged to profit or loss in the period to which they relate. |

| 6. | TAXATION - continued |
| The standard rate of UK corporation tax is 25%. On 3 March 2021, the Chancellor of the Exchequer announced that the main rate of corporation tax in the United Kingdom would rise to 25% with effect from 1 April 2023 for companies earning annual taxable profits in excess of £250,000. Companies earning annual taxable profits of £50,000 or less will continue to pay corporation tax at 19% with a marginal rate adjustment for companies earning annual taxable profits between the two levels. These changes had been substantively enacted at the balance sheet date and therefore deferred tax is recognised at 25%. |
