Smoke and CO alarm test record

The regulations require a test on day one. This one-page log is what proves it.

Compliance & safety · Updated 5 August 2026

Overview

Landlords must fit a smoke alarm on every storey used as living accommodation and a carbon monoxide alarm in any room with a fixed combustion appliance other than a gas cooker, and must test all alarms on the first day of the tenancy.

Why it matters

Local authorities can issue a remedial notice and a financial penalty. In practice the day-one test is the point most often challenged, and only a signed record answers it.

Legal requirements

  • Smoke alarm on each storey used as living accommodation.
  • Carbon monoxide alarm in rooms with a fixed combustion appliance, excluding gas cookers.
  • Test all alarms on the first day of the tenancy.
  • Repair or replace a faulty alarm as soon as reasonably practicable once reported.

Common mistakes

  • Fitting alarms but never recording the day-one test.
  • Missing a solid fuel appliance or a gas boiler in a cupboard.
  • Relying on a tenant''s verbal confirmation that alarms work.
  • Not replacing sealed units at the end of their life.

Practical guidance

  • Test with the tenant present at handover and have them sign the log.
  • Photograph each alarm in place with the test date noted in the file.
  • Ask the tenant to test monthly and report faults immediately.
  • Diarise replacement dates for sealed ten-year units.
