Notes to the Financial Statements

for the year ended 31 December 2025

1. | STATUTORY INFORMATION

| Cleantech Group Europe 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 (£).

2. | ACCOUNTING POLICIES

| Basis of preparing the financial statements

| 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" including the provisions of Section 1A "Small Entities" and the Companies Act 2006. The financial statements have been prepared under the historical cost convention.

| Revenue recognition

| Turnover is measured at the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes.

| Tangible fixed assets

| Depreciation is provided at the following annual rates in order to write off each asset over its estimated useful life.

| Plant and machinery etc | - | 33% on cost

| All tangible fixed assets are at cost less accumulated depreciation. Cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

| Assets held under finance lease are depreciated in the same manner as owned assets.

| Renewals, repairs and maintenance are charged to profit and loss during the period in which they are incurred.

| Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives, using a mixture of methods. The depreciation bases are as detailed above.

| The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.

| Gains and losses on disposal are determined by comparing the proceeds with the carrying amount and are credited or charged to the income statement.

| Impairment of fixed assets

| At each balance sheet date, the Company reviews the carrying amounts of its property, plant and equipment to determine whether there is any indication that any items of property, plant and equipment have suffered an impairment loss. If any such indications exists, the recoverable amount of an asset is estimated in order to determine the extent of the impairment loss, if any. Where it is not possible to estimate the recoverable amount of the asset, the Company estimates the recoverable amount of the cash-generating unit to which the asset belongs.

| If the recoverable amount of an asset is estimated to be less that its carrying amount, the carrying amount of the asset is reduced to its recoverable amount. Impairment loss is recognised as an expense immediately.

| Where an impairment loss subsequently reserves, the carrying amount of the asset is increased to the revised estimate of its recoverable amount that would have been determined (net of depreciation) had no impairment loss been recognised for the asset in the prior years. A reversal of an impairment loss is recognised as income immediately.
