- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“In auditing the financial statements, we have concluded that the trustees' 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 group or the parent charitable 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
- “re-launch our breeding programme during the past year, marking an important milestone in securing the future supply of dogs for our assistance and detection work. Shortly before Christmas, we welcomed a new litter of puppies”
- “new five-year strategy agreed with the Board of Trustees in March 2025”
- “made the difficult decision to pause our Colorectal Cancer study until additional funding is secured, and launched an urgent appeal at the start of 2025/26”
- “Our Bio Detection Research has seen encouraging progress, with notable advancements in our UTI detection pilot, including securing new partnerships with a local care home group, and provisional funding to accelerate this work.”
- “published two significant papers since the last annual report: Canine Bladder Cancer detection in December 2024 and our Parkinson's study in July 2025.”

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
