The duty in plain English
England’s smoke and carbon monoxide alarm rules for private landlords are about working alarms in the right places, not a particular brand. Typically: smoke coverage on each storey used as living accommodation, and CO alarms in rooms with a fixed combustion appliance (other than a gas cooker, under the current England rules).
Rules differ in Scotland, Wales and Northern Ireland. Always check the nation you let in.
Testing on the day of let
Landlords are generally expected to check alarms on the day the tenancy starts and to repair or replace them once a tenant reports a fault. Keep a simple note of that check in the tenancy file.
Tenants should still test weekly. The landlord duty does not disappear because a tenant forgot.
When a Grade D set is not enough
Shared houses, inner rooms and licence conditions often need a designed fire alarm system rather than a handful of domestic detectors. An FRA is the honest way to decide — not a guess from a product catalogue.
How we can help
We supply and position alarms, replace life-expired units, and quote a wider system when the house needs one. Start at smoke and CO alarms or contact.
Common questions
Do I need a CO alarm next to a gas cooker?
England’s current private-rented rules treat gas cookers differently from other fixed combustion appliances. Confirm the latest wording for your property type before you buy.
How long do alarms last?
Most sealed units have a printed end-of-life date, commonly around 10 years. Replace when that date arrives or when the unit fails a test.
