Frequently Asked Questions
How much does it cost to install smoke alarms?
A single mains-powered smoke detector costs from £85 installed. A basic 3-alarm interlinked system for a 2-3 bed house costs £280-£350. Full house coverage with 5-6 alarms costs £450-£600 depending on property size and cable routing.
Do landlords need to install fire alarms?
Yes. Since 2015, landlords must have at least one smoke alarm on each floor and a carbon monoxide alarm in rooms with solid fuel appliances. HMOs have stricter requirements including Grade D LD2 systems with heat alarms in kitchens.
What is a Grade D LD2 fire alarm system?
Grade D means mains-powered with battery backup. LD2 means detection in escape routes plus high-risk rooms like kitchens and living rooms. This is the minimum standard for HMOs and new-build homes under Building Regulations.
Should smoke alarms be interlinked?
Yes, building regulations require interlinked smoke alarms in new builds and conversions. When one alarm detects smoke, all alarms sound together, giving everyone in the property maximum warning time to escape.
How often should fire alarms be tested?
Test smoke alarms weekly using the test button. Replace batteries annually (for alarms with replaceable batteries). Replace the entire alarm every 10 years. Landlords must arrange testing at the start of each new tenancy.
