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

“In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate.

Significant events
- “A fire incident in February 2024 at our Aberdeen site was a risk factor on future performance due to the initial disruption and extended timeline to get services re-instated and operational. Temporary arrangements utilising less equipment until the site is rebuilt, created initial challenges in remaining competitive and led to increases operating costs. This is expected to be complete in quarter 4 of 2025.”
