Audit opinion

Unqualified (clean)

Going concern

Affirmed

“Despite the net current liabilities position of the company, the directors believe that preparing the financial statements on the going concern basis is appropriate having given consideration to the funding requirements of the company together with the confirmation of continued financial support from the ultimate parent company (which, following completion of the Bridgepoint transaction, is Sparkle Topco Limited) and an expectation that the amount owed by and owed to the group undertakings will not be settled within 12 months. The directors have received confirmation that the ultimate parent company will support the company for at least one year after these financial statements are signed, and therefore the going concern of the company is dependent on the going concern of the parent company.”

Significant events

• “Subsequent to the year end, on 18 July 2025, the group entered into a binding Share Purchase Agreement whereby funds managed by Bridgepoint Advisors Limited ('Bridgepoint') would acquire a majority shareholding in the company's ultimate parent undertaking, Turnstone Equityco 1 Limited ('the Bridgepoint transaction'). The transaction subsequently completed on 14 October 2025, with Sparkle Bidco Limited acquiring 100% of the share capital of Turnstone Equityco 1 Limited. The group's existing third-party borrowings were also re-financed in full on the same date.”
• “During the year, the company closed two practices due to being either loss making or having marginal profitability and therefore management does not consider there to be a viable recovery option (2024: one closure). In addition, two existing practices were closed and one new site opened as a result of the organic growth strategy, which involves the merger, relocation or expansion of smaller practices with limited growth opportunities, which are typically constrained both by size and/or a sub-optimal location, into larger and better located premises, typically in high footfall high street or retail park locations.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. Periods don't have to be exactly 12 months apart — a long or short period (typical around incorporation or year-end changes) will distort the comparison. Lines a company doesn't report are omitted. About these numbers
