How to run it without gaps
- Hold one asset register with the inspection interval against each asset, not a folder of certificates.
- Date-stamp every certificate on receipt and diary the next due date at the same moment.
- Keep a single evidence pack you can hand to an insurer, tenant or enforcement officer within a day.
- Record remedial actions against the inspection that raised them, with a closure date.
- Treat CIBSE Guide M intervals as the planning baseline where no statutory interval exists.
