NOTES TO THE FINANCIAL STATEMENTS

For the financial year ended 31 March 2025
1. Accounting policies

The principal accounting policies are summarised below. They have all been applied consistently throughout the financial year and to the preceding financial year, unless otherwise stated.

General information and basis of accounting

Synergie Environ Limited (the Company) is a private company, limited by shares, incorporated in the United Kingdom under the Companies Act 2006 and is registered in Scotland. The address of the company's registered office is 65 Sussex Street, Glasgow, G41 1DX, Scotland, United Kingdom. The principal place of business is 1.1 Queens House, 19 St Vincent Place, Glasgow, G1 2DT.

These financial statements have been prepared in accordance with FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (“FRS 102”) and the requirements of the Companies Act 2006 as applicable to companies subject to the small companies regime. The disclosure requirements of section 1A of FRS 102 have been applied other than where additional disclosure is required to show a true and fair view

The financial statements are prepared in sterling, which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest £.

The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below.

The company has taken advantage of the following disclosure exemptions:

•from the financial instrument disclosures, required under FRS 102 Section 11 Basic Financial Instruments paragraphs 11.39 to 11.48A and Section 12 Other Financial Instruments paragraphs 12.26 to 12.29;
•not to disclose details of transactions and balances with other members of the group.

Synergie Environ Limited is a wholly owned subsidiary of PD&MS Energy (Aberdeen) Limited and the results of Synergie Environ Limited are included in the consolidated financial statements of RSK Group Limited (the 'Group').

Going concern

At the time of approving the financial statements, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for at least twelve months from the date of signing the financial statements. Thus the directors have continued to adopt the going concern basis of accounting in preparing the financial statements.

The going concern assumption is based upon confirmation of support from the ultimate parent company of Synergie Environ Limited. A letter of support has been provided which confirms that the ultimate parent company will continue to support the company by not demanding repayment of any amounts loaned to the company as well as providing sufficient funding and financial support as required to enable Synergie Environ Limited to discharge all its liabilities and continue as a going concern for a minimum period of at least 12 months from the date of signing the audited financial statements.

Budgets for the financial year to 31 March 2026 have been prepared by directors and management which forecast increasing gross margins and a profit for the year. The directors are confident that with the synergies identified within the group, and with the recruitment of well experienced management, the company can meet their goals and achieve the expected growth and profitability in the future. Thus, the directors continue to adopt the going concern basis in preparing the financial statements.

After the closure of the 2025 financial year, there were no further events that could have significant effects on the company's financial statements.

Turnover

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 contracts for the provision of professional services is recognised by reference to the stage of completion when the stage of completion, costs incurred and costs to complete can be estimated reliably. The stage of completion is calculated by comparing costs incurred, mainly in relation to contractual hourly staff rates and materials, as a proportion of total costs. Where the outcome cannot be estimated reliably, revenue is recognised only to the extent of the expenses recognised that it is probable will be recovered.

Employee benefits

Short term benefits
The cost of any unused holiday entitlement is recognised in the period in which the employee’s services are received.

Termination benefits are recognised as an expense when the company is demonstrably committed to terminate the employment of an employee or to provide termination benefits.

Defined contribution schemes
The company operates a defined contribution scheme. The amount charged to the Profit and Loss Account in respect of pension costs and other post-retirement benefits is the contributions payable in the financial year. Differences between contributions payable in the financial year and contributions actually paid are included as either accruals or prepayments in the Balance Sheet.

Taxation

Current tax
The tax currently payable is based on taxable profit for the year. Taxable profit differs from net profit as reported in the profit and loss account because it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting end date.

Deferred tax
Deferred tax liabilities are generally recognised for all timing differences and deferred tax assets are recognised to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits. Such assets and liabilities are not recognised if the timing difference arises from goodwill or from the initial recognition of other assets and liabilities in a transaction that affects neither the tax profit nor the accounting profit.

The carrying amount of deferred tax assets is reviewed at each reporting end date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised. Deferred tax is charged or credited in the profit and loss account, except when it relates to items charged or credited directly to equity, in which case the deferred tax is also dealt with in equity. Deferred tax assets and liabilities are offset when the company has a legally enforceable right to offset current tax assets and liabilities and the deferred tax assets and liabilities relate to taxes levied by the same tax authority.

Tangible fixed assets

Tangible fixed assets are stated at cost or valuation, net of depreciation and any provision for impairment. Depreciation is provided on all tangible fixed assets, other than investment property and freehold land, at rates calculated to write off the cost or valuation, less estimated residual value, of each asset on a straight-line or reducing balance basis over its expected useful life, as follows:

Plant and machinery etc. 25 % reducing balance
3 years straight line

The gain or loss arising on the disposal of an asset is determined as the difference between the sale proceeds and the carrying value of the asset, and is credited or charged to profit or loss.

Impairment of assets

Assets, other than those measured at fair value, are assessed for indicators of impairment at each Balance Sheet date. If there is objective evidence of impairment, an impairment loss is recognised in the Profit and Loss Account as described below.

Cash and cash equivalents

Cash and cash equivalents are basic financial assets and include cash in hand, deposits held at call with banks, other short-term liquid investments with original maturities of three months or less, and bank overdrafts. Bank overdrafts are shown within borrowings in creditors: amounts falling due within one year.

Financial instruments

Financial assets and financial liabilities are recognised when the Company becomes a party to the contractual provisions of the instrument.

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 deducting all of its liabilities.

Financial assets and liabilities are only offset in the Balance Sheet when, and only when there exists a legally enforceable right to set off the recognised amounts and the Company intends either to settle on a net basis, or to realise the asset and settle the liability simultaneously.

Basic financial assets
Basic financial assets, which include debtors and cash and bank balances, are initially measured at transaction price including transaction costs and are subsequently carried at amortised cost using the effective interest method 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. Financial assets classified as receivable within one year are not amortised.

Basic financial liabilities
Basic financial liabilities, including creditors, bank loans, loans from fellow group companies and preference shares that are classified as debt, are initially recognised at transaction price unless the arrangement constitutes a financing transaction, where the debt instrument is measured at the present value of the future payments discounted at a market rate of interest. Financial liabilities classified as payable within one year are not amortised.

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

Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Amounts payable are classified as current liabilities if payment is due within one year or less. If not, they are presented as non-current liabilities. Trade creditors are recognised initially at transaction price and subsequently measured at amortised cost using the effective interest method.

Equity instruments
Equity instruments issued by the company are recorded at the fair value of cash or other resources received or receivable, net of direct issue costs. If payment is deferred and the time value of money is material, the initial measurement is on a present value basis. Dividends payable on equity instruments are recognised as liabilities once they are no longer at the discretion of the company.

Provisions

Provisions are recognised when the company has a present obligation (legal or constructive) as a result of a past event, it is probable that the company will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation.

The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the Balance Sheet date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows (when the effect of the time value of money is material).

When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, a receivable is recognised as an asset if it is virtually certain that reimbursement will be received and the amount of the receivable can be measured reliably.

Research and development

Expenditure on research activities is written off to the profit and loss account as incurred.
Development expenditure is also written off as incurred unless the recognition criteria in FRS 102 Section 18 are met, in which case it is capitalised as an intangible asset. To date, no development expenditure has met these criteria.
Income from the Research and Development Expenditure Credit (RDEC) is recognised as other operating income when there is reasonable assurance that the conditions for claiming have been met and the income is receivable. RDEC income is presented above operating profit and is not offset against related expenditure.
