Every obligation, with the rule written down.

Annual gas safety check by a Gas Safe registered engineer. Required for any rental property with a gas appliance (boiler, gas hob, gas fire, gas water heater).

Inspection of the fixed electrical installation by a qualified electrician (NICEIC, NAPIT, ELECSA or equivalent). Required for all new tenancies from 1 July 2020; required for existing tenancies from 1 April 2021.

Required to market or let any property. Must achieve a minimum rating (currently E for new tenancies; C target under MEES reform — verify current threshold). Re-assessed every 10 years or when material changes are made to the property.

Required for HMOs and any property with communal areas. The statutory duty is "suitable and sufficient" rather than a fixed cycle, but the accepted best practice — and what we monitor — is annual review.

Required for any property let to 5+ occupants from 2+ households (mandatory HMO), plus any property in a council's additional or selective licensing area. The cycle varies by council — most are 5 years, some are 3. ComplianceTrack lets you override per property.

Duty of care to assess the risk of Legionella bacteria in the hot and cold water systems. No fixed statutory cycle, but the HSE's ACOP L8 and HSG274 recommend review every 2 years or on change of tenancy.

One working smoke alarm on every floor used as living accommodation. A CO alarm in any room with a solid fuel appliance, and (since 2022) in any room with a gas appliance used as living accommodation. Landlord must check alarms are working at the start of every tenancy.

Check every adult tenant's right to rent in the UK before the tenancy starts. For tenants with time-limited immigration status, the check must be repeated before the visa expires.
