Smoke and CO Alarm Checks in London

Private landlords in England must fit a smoke alarm on every storey used as living accommodation, and a carbon monoxide alarm in any room used as living accommodation that contains a fixed combustion appliance (gas cookers excepted). Alarms must be checked to be working at the start of each new tenancy, and repaired or replaced once a fault is reported. We coordinate these checks for letting agents and portfolio landlords, often alongside other move-in certificates.

What the check covers

• Smoke alarms present on each storey and working
• CO alarms present where there is a fixed combustion appliance, such as a boiler or wood burner
• A written record of what was found, for your file

When to book it

• At the start of each new tenancy
• When a tenant reports a faulty alarm
• When combustion appliances are installed or changed

How we help

1. Send the addresses and the tenancy start dates.
2. We confirm scope and quote per property.
