Fire safety in homes has been under increasing scrutiny, and 2026 has brought further refinements to the guidance around smoke, heat, and carbon monoxide alarms. Whether you are a landlord with multiple properties or a homeowner who wants to keep your family safe, understanding the current requirements is essential.
The Current Requirements
All residential properties in England must have at least one smoke alarm on every storey where there is a room used wholly or partly as living accommodation. A heat alarm is required in every kitchen. Carbon monoxide alarms are mandatory in any room containing a fixed combustion appliance such as a gas boiler, fire, or log burner.
The alarms must be interlinked so that if one triggers, they all sound. This can be achieved with hardwired interconnected systems or with sealed battery wireless units that communicate by radio frequency. Mains-powered hardwired alarms with battery backup are considered the most reliable and are strongly recommended.
Hardwired vs Battery-Only Alarms
- Hardwired interconnected alarms are powered from the lighting circuit and have a ten-year sealed battery backup.
- They communicate via a dedicated interlink cable or wirelessly if the compatible models are chosen.
- They cannot be easily removed or disabled by tenants, which is why landlords prefer them.
- Battery-only alarms must be tamper-proof with sealed ten-year batteries to comply with current standards.
- Landlords must test alarms at the start of each tenancy and record the results.
Where Alarms Should Be Positioned
Smoke alarms should be mounted on the ceiling in the centre of the room or hallway, at least 300mm from walls and light fittings. They should not be placed directly above cookers or in bathrooms where steam can cause false alarms. Heat alarms in kitchens should be positioned away from cooker hoods and windows where draughts might prevent detection.
Expert Tip
D3C Electrical installs Aico mains-powered alarm systems with wireless interlink across Leicester and Leicestershire. These systems meet all current requirements, include a central test switch, and can integrate with carbon monoxide and flood sensors for complete property protection.
For landlords, failing to comply with alarm regulations can result in fines of up to £5,000 per property and may invalidate insurance. For homeowners, proper alarm coverage is the single most effective way to reduce the risk of fire-related injury or death.
