Year-on-year

FY2024 → FY2025 · period ending 2025-03-31 vs 2024-04-30

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers

Audit opinion
Unqualified (clean)
Going concern
Material uncertainty disclosed

“We draw attention to note 2.3 to the financial statements which explains that the members intend to cease the trade of the LLP when the partnership's business is incorporated via a transfer of the trade and net assets to a newly incorporated limited company. Therefore the members do not consider it appropriate to adopt the going concern basis of accounting in preparing the financial statements. Accordingly the financial statements have been prepared on a basis other than as a going concern as described in note 2.3. Our opinion is not modified in respect of this matter. The financial statements have been prepared on a basis other than going concern. As detailed in Note 23 the LLP is expected to cease trading during 2026 when its trade, certain assets (including the LLP's subsidiaries), and liabilities are transferred to a newly incorporated limited company under the control of the LLP's partners. The LLP will continue to operate as normal until the transfer of trade and net assets occurs, and the business will continue to trade through that limited company after the transfer date.”
