“The group's forecasts and projections for the next twelve months show that the group will continue growing thanks to the additional headroom created by the unutilized credit facility. These forecasts support the ability of the group to remain a going concern and to be able to trade and to meet its debts as they fall due.”

Significant events
- “The group started to successfully provide intervention services to at fault insurers, generating additional revenue and profit from this new business line.”
- “On Medical Limited revenue (£964k) continued decreasing versus previous years as a result of ceasing taking new medical instructions since 1 April 2024.”
- “Winn Solicitors Limited ended the financial year with a 32% increase in legal fees, thanks to the significant increase in Non-Pl legal fees (46%) and PI Fixed Recoverable Costs (38%). MOJ portal revenue grew by 19%.”
- “The group witnessed strong cash generation during this year with £38.8m of cash-flow from operating activities. This helped the group to fully repay the £26.8m drawn at the end of the previous year from NatWest RCF.”

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
