The 2022 law explained
2022 Regulations: what landlords in SW2 must do
The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 apply to all private rented properties in England, including every address in the SW2 postcode (Brixton & Streatham Hill). Since 1 October 2022, landlords must have a working CO alarm in every room that contains a gas boiler, gas fire, or gas cooker.
For a typical SW2 flat or house, this means: a CO alarm in the boiler cupboard or utility room, a CO alarm in the kitchen (if there is a gas hob or oven), and a CO alarm in any room with a gas fire. Local authorities can inspect and issue fines of up to £5,000 per property for non-compliance.
Alarms must be in repair at the start of each tenancy and replaced when they reach their expiry date. Our engineers cover the entire SW2 postcode and can install compliant alarms with same-day availability on most days.
Alarm types and what to do if one sounds
Sealed battery vs mains-powered — and what to do if an alarm sounds
For most SW2 properties, sealed 10-year battery CO alarms are the straightforward choice — no electrician required, no ongoing battery changes, and full compliance with BS EN 50291-1. They are replaced as complete units at the end of their working life, typically after 7-10 years.
Mains-powered alarms with battery backup are more suitable for HMOs and larger properties where an interlinked system is required under the premises licence. Our engineers can advise on the correct specification for your SW2 property during the initial visit.
If a CO alarm sounds in a SW2 property: evacuate immediately, open windows and doors, call 0800 111 999 (National Gas Emergency Service) from outside, and do not return until a Gas Safe engineer has cleared the property. Carbon monoxide is invisible and odourless — early symptoms of poisoning include headache, nausea, and dizziness, which are often mistaken for other conditions.

Carbon monoxide alarm SW2: frequently asked
What does the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 require?
Since 1 October 2022, all private landlords in England must fit a carbon monoxide alarm in every room used as living accommodation that contains a fixed combustion appliance — including rooms with gas boilers, gas fires, and gas cookers. The alarm must be in working order at the start of each new tenancy.
Where must carbon monoxide alarms be placed in a SW2 property?
A CO alarm must be fitted in every room in your SW2 property containing a gas appliance. For most properties this means the boiler cupboard or utility room, the kitchen if there is a gas cooker, and any room with a gas fire. Alarms should be at head height, at least 1 metre from the appliance.
What type of carbon monoxide alarm is compliant with the 2022 Regulations?
Alarms must meet BS EN 50291-1. Both mains-powered and sealed 10-year battery alarms are acceptable provided they are tested at each tenancy start and replaced before their stated expiry date.
Can I test the carbon monoxide alarm myself?
The test button checks the sounder and battery but not the electrochemical sensor. Full sensor verification requires professional equipment. Landlords should arrange professional testing at each tenancy renewal. Sensors expire after 7-10 years regardless of whether CO has been detected.
