Audit & accounting basis
- Accounting basis
- FRS 102
- Reporting scope
- Standalone (parent only)
- Auditor
- Forvis Mazars LLP
- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“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. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.”
Significant events
- “There were a number of notable contract awards and extensions in the year with both existing and new customers. In addition, the pipeline of opportunities has continued to grow which gives the Directors confidence the business is well positioned to achieve significant progress in the next financial year and beyond.”
- “During 2025 we agreed and signed a new lease with our landlord and completed the 2nd floor expansion with a new office suite catering for 120 staff.”

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
