Structure checks
Sheets, headers, required fields, data types, date formats, field lengths and file limits. A structural error blocks a ready result.
Published method
What UK Filing checks — and what it does not.
Every supported workflow separates deterministic file checks from warnings that need your judgement. The exact framework, template version and source-review date are shown before purchase.
Three levels of implemented checks
Plausibility warnings
Duplicate identities, arithmetic differences, reporting periods and unusual changes from the prior recorded month. A warning asks for review and does not decide the business facts.
Framework-specific rules
Only rules listed for the exact verified coverage entry, such as published identifiers, allowed values and supported template combinations.
What the evidence records
The free validator can download a local report with the file hash, coverage version, checks run, known limits and findings. A paid monthly run also records compact rule and count metadata, the output hash, approval and an optional customer-entered submission reference.
A validation report or submission reference is a record of the implemented checks and customer action. It is not portal acceptance, proof of operator receipt, a legal opinion or a guarantee that the source export is complete.
How coverage stays honest
- An exact agreement, official template and documented rules are reviewed.
- Valid and invalid fixtures exercise the listed rules.
- The catalogue publishes the template version, verification date, next source-review date, checks and exclusions.
- Checkout stops automatically after the review date until the entry is checked and re-dated.
- A changed or unsupported framework returns to “Framework review required”.
