- Going concern
- Affirmed
“The directors have reviewed the forecast financial statements for 12 months following the approval of the financial statements and consider the business will continue to trade into this period with no material uncertainty, weathering fluctuations in the global economy. The expectation for the year ending 31 December 2025 is for profits to be similar to 2024. With our ability to rely on self-funding and coupled with cash reserves at year end of £2,200,647 (2023: £2,166,784), the directors are satisfied that the business is a going concern.”

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
