Strategic Report
for the Year Ended 31 December 2024

The directors present their strategic report for the year ended 31 December 2024.

REVIEW OF BUSINESS
Sirius Engineering Group is a design & build enabling works specialist delivering fully integrated ground engineering services to the development sector.

The Group via its subsidiaries delivers a full range of integrated pre-construction services to facilitate and enable the development of both brownfield and greenfield land.

Operating across the United Kingdom from regional offices in Durham, Leeds, Warrington and Llanelli its contracting services include Demolition, Earthworks. Remediation, Drilling and Civil Engineering all supported by a cutting-edge Plant and Technologies division.

As consultants, Sirius also provides specialist Geotechnical, Environmental and Planning professional services.

This unique combination of services provides its clients with confidence to build on even the most complex and challenging sites, often on a design & build basis.

Operating since 2003, Sirius has developed a large, highly stable, repeat-business client base across several principal sectors including residential, commercial and retail development, waste management and renewable energy.

Sirius Remediation Limited is one of the largest subsidiaries in the group, offering a full range of essential site enabling, bulk earthworks, soil and groundwater remediation and ground engineering solutions.

The ability to also delivery primary infrastructure in combination with initial earthworks or remediation works is a key differentiator for the business (in conjunction with Sirius Group companies) and can assist in delivering significant cost and programme savings for its clients.

The results for the year and the financial position of the company are set out on pages 9 to 22.

Key Performance Indicators:

The Company's KPIs for the year were:
2024 2023
£'000s £'000s

Turnover 19,440 18,770

Gross Profit % 24.4% 18.2%

Sirius Remediation Limited recorded turnover growth of 4% in 2024 and a strong, improving profitability position.

The first half of the year saw the business continue to be impacted by the macroeconomic headwinds from 2023, higher inflation, higher mortgage costs and lower levels of consumer confidence suppressing housing market activity. Despite these pressures, regional performance varied. The North-East demonstrated notable resilience, maintaining steady demand while other areas experienced more volatility.

As the year progressed, conditions started to improve, inflation reduced and mortgage rates started to decline, leading to a notable uplift in market confidence and demand. The final quarter of 2024 showed strong signs of recovery, leading to a busy end to the year and a full order book heading into 2025 which is already proving to be a strong year for both the business and the wider group. The group is in a strong position to benefit from this upturn with a strong balance sheet, cutting edge plant fleet and an experienced, skilled workforce.

Sirius Remediation Limited (Registered number: 04860112)

Strategic Report
for the Year Ended 31 December 2024

The government pledged in June 2024 to "get Britain building again" with a target of 1.5m houses in the coming 5 years. The UK remains chronically short of new housing stock and so the long-term fundamentals of our key market remain strong.

Whilst our key market remains housebuilding, part of our strategic plan is a commitment to leverage the experience of the group into adjacent markets to introduce further diversification into our portfolio. Leveraging the group's wider expertise, we began expanding into adjacent markets-an effort that is now gaining real momentum as we move through 2025.

Employee Ownership
2023 was a key milestone in the history of the group. To coincide with it's 20th Anniversary, the group transitioned to becoming a 100% Employee-Owned business on the 17th October 2023. This allows for a long-term succession plan that secures the future of the group into the hands of the people who have helped to build it over the years.

PRINCIPAL RISKS AND UNCERTAINTIES
The principal risks and uncertainties facing the company and how they may affect its performance, position or future prospects are set out below:

Health, Safety and Environmental
The Company are subject to health & safety and environmental risks, implicit in the work undertaken. The Board and business unit leads promote a strong health and safety culture underpinned by procedures that are continually assessed to ensure best practice. Ongoing health & safety training is provided to employees and maintained. The group employs 2 full time specialist employees and use external consultants where required to protect the health, safety and welfare of its employees and clients.

Financial Risk Management
In common with other businesses, the company aims to minimize financial risk wherever possible. The measures used include the preparation of budgets and forecasts, regular monitoring of actual performance against these forecasts and ensuring adequate sources of finance are in place to meet the requirement of the business.

The company's principal financial instruments comprise bank balances, hire purchase agreements, trade and subcontract creditors and trade debtors to raise funds for, and finance, the company's operations.

Credit Risk
Amounts receivable relate largely to applications on contracts across our stable customer base. The company has policies concerning credit offered to customers and regularly monitor amounts outstanding for both time and credit limit.

Liquidity Risk
Through negotiation with clients and suppliers we aim to manage our working capital and cash availability within certain limits. Forecasting is undertaken to ensure sufficient funds are available to meet amounts due.

The company has the support of Sirius Engineering Group Limited and will continue to do so for the next 12 months.

STATEMENT OF DIRECTORS' RESPONSIBILITIES
The directors are responsible for preparing the Strategic Report, 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.

Report of the Directors
for the Year Ended 31 December 2024


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.

ON BEHALF OF THE BOARD:




S Robinson - Director


22 September 2025

Report of the Independent Auditors to the Members of
Sirius Remediation Limited

Opinion
We have audited the financial statements of Sirius Remediation Limited (the 'company') for the year ended 31 December 2024 which comprise the Statement of Comprehensive Income, 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 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 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 directors are responsible for the other information. The other information comprises the information in the Strategic Report and 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 Strategic Report and the Report of the Directors for the financial year for which the financial statements are prepared is consistent with the financial statements; and
- the Strategic Report and the Report of the Directors have been prepared in accordance with applicable legal requirements.

Report of the Independent Auditors to the Members of
Sirius Remediation Limited


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 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.

Responsibilities of directors
As explained more fully in the Statement of Directors' Responsibilities set out on page four, 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.

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.

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.

Based on our understanding of the industry, we have considered applicable laws and regulations which may be fundamental to the company's ability to operate or to avoid a material penalty, and we considered the extent to which non-compliance might have a material effect on the financial statements. We considered management's incentives and opportunities for fraudulent manipulation of the financial statements (including the risk of override of controls), and determined that the principal risks were related to the posting of inappropriate manual journal entries to manipulate financial performance, management bias in significant accounting estimates and any significant one-off or unusual transactions.

We discussed among the audit engagement team the opportunities and incentives that may exist within the organisation for fraud and how and where fraud might occur in the financial statements.


Report of the Independent Auditors to the Members of
Sirius Remediation Limited


Auditors' responsibilities for the audit of the financial statements (continued)
Audit procedures performed by the engagement team included:

- Enquiry of management, those charged with governance and the entity's solicitors 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.
- Auditing the risk of management override of controls, including through testing journal entries and other
adjustments for appropriateness, and evaluating the business rationale of significant transactions outside the
normal course of business.
- Challenging estimates and judgements made by management in their significant accounting estimates.
- Revenue recognition; agreeing a sample of revenue transactions to gain assurance over the occurrence and
accuracy of revenue and also to ensure revenue has been recognised in the correct period.

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. The 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 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.

for the Year Ended 31 December 2024

1. STATUTORY INFORMATION

Sirius Remediation Limited is a private company, limited by shares , registered in England and Wales. The company's registered number and registered office address can be found on the Company Information page.

The presentation currency of the financial statements is the Pound Sterling (£).


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

2. ACCOUNTING POLICIES

General information and basis of preparation
These financial statements have been prepared in accordance with Financial Reporting Standard 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland" and the Companies Act 2006. The financial statements have been prepared under the historical cost convention.

Financial Reporting Standard 102 - reduced disclosure exemptions
The company has taken advantage of the following disclosure exemptions in preparing these financial statements, as permitted by FRS 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland":

the requirements of Section 7 Statement of Cash Flows;
the requirement of paragraph 3.17(d).

Turnover
Turnover is stated net of VAT and is recognised when the significant risks and rewards are considered to have been transferred to the buyer. Turnover for the supply of services represents the value of services provided under contracts to the extent that there is a right to consideration and is recorded at the fair value of the consideration received or receivable. Where a contract has only been partially completed at the balance sheet date turnover represents the fair value of the service provided to date based on the stage of completion of the contract activity at the balance sheet date.

Construction contracts
Where the outcome of a construction contract can be estimated reliably, revenue and costs are recognised by reference to the stage of completion of the contract activity at the balance sheet date. Stage of completion is measured by reference to the right to consideration in respect of performance of contractual obligations.
Where the outcome of a construction 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 it is probable that total contract costs will exceed total contract revenue, the expected loss is recognised as an expense immediately.

2. ACCOUNTING POLICIES - continued

Tangible fixed assets
Depreciation is provided at the following annual rates in order to write off each asset over its estimated useful life or, if held under a finance lease, over the lease term, whichever is the shorter.
Plant and machinery - 20% on reducing balance
Fixtures and fittings - 25% on cost
Motor vehicles - 33% on cost
Computer equipment - 33% on cost and 25% on cost

Tangible fixed assets are stated at cost (or deemed cost) less accumulated depreciation and accumulated
impairment losses. Cost includes costs directly attributable to making the asset capable of operating as intended

Impairment
Assets not measured at fair value are reviewed for any indication that the asset may be impaired at each balance sheet date. If such indication exists, the recoverable amount of the asset, or the asset's cash generating unit, is estimated and compared to the carrying amount. Where the carrying amount exceeds its recoverable amount, an impairment loss is recognised in profit or loss unless the asset is carried at a revalued amount where the impairment loss is a revaluation decrease.

Taxation
Current tax represents the amount of tax payable or receivable in respect of the taxable profit (or loss) for the current or past reporting periods. It is measured at the amount expected to be paid or recovered using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date.

Deferred tax represents the future tax consequences of transactions and events recognised in the financial statements of current and previous periods. It is recognised in respect of all timing differences, with certain exceptions. Timing differences are differences between taxable profits and total comprehensive income as stated in the financial statements that arise from the inclusion of income and expense in tax assessments in periods different from those in which they are recognised in the financial statements. 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.

Deferred tax is measured using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date that are expected to apply to the reversal of timing differences.

Research and development
Expenditure on research and development is written off in the year in which it is incurred.


Hire purchase and leasing commitments
Assets obtained under hire purchase contracts or finance leases are capitalised in the balance sheet. Those held under hire purchase contracts are depreciated over their estimated useful lives. Those held under finance leases are depreciated over their estimated useful lives or the lease term, whichever is the shorter.

The interest element of these obligations is charged to profit or loss over the relevant period. The capital element of the future payments is treated as a liability.

Rentals paid under operating leases are charged to profit or loss on a straight line basis over the period of the lease.

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.

Amounts recoverable on contracts
Amounts recoverable on contracts are stated at cost plus attributable profit to the extent that such profit is reasonably certain and after making provision for any foreseeable losses in completing contracts, less payments on account received.

2. ACCOUNTING POLICIES - continued

Debtors and creditors receivable/payable within one year
Debtors and creditors with no stated interest rate and receivable or payable within one year are recorded at transaction price. Any losses arising from impairment are recognised in the profit and loss account in other
administrative expenses.

Judgements and key sources of estimation uncertainty
In the application of the companies accounting policies, which are described above, the directors are required to make judgements, estimates and assumptions about the carrying amounts 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 if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

The judgement (apart from those involving estimations) that management has made in the process of applying the entity's accounting policies and that has the most significant effect on the amounts recognised in the financial statements is the stage of completion of contracts and revenue recognition.

The company undertakes a number of long term construction contracts. Accounting for these contracts requires a number of assumptions and estimates to be made in relation to the stage of completion and expected outcome of the contract. Each contract has an expected value and is costed appropriately to give an expected margin. Any future changes to estimates of contract revenue or contract costs resulting in a change to the estimated loss or profit of the contract is regularly reviewed by management to ensure accurate reporting of revenue recognition.
