How Much Does Fire Alarm Installation Cost?
Fire alarm installation starts from £210 per alarm for standard installations. The final price depends on the property type, number of alarms required, wiring access, alarm grade, system category, ceiling type, existing electrical condition and whether the alarms need to be interconnected.
For larger properties, HMOs, communal buildings, commercial units or Grade A systems, a site review may be required before confirming the final price.
Simple smoke alarm installation is usually quicker and lower cost. Larger properties, HMOs, commercial buildings and Grade A fire alarm systems may require more planning because the alarm coverage must match the fire risk, escape routes and building layout.
Our engineer can attend the property, confirm suitable alarm positions, complete the installation and test the system before handover.

BS 5839-6 Domestic Compliance
Recommendations for fire detection and alarm systems in domestic premises.
BS 5839-1 Commercial Compliance
Recommendations for fire detection and alarm systems in non-domestic buildings.
BS 5839-6 uses LD categories to describe the level of life protection provided by smoke, heat and fire detection alarms. The correct category depends on the property type, layout, occupancy risk and whether it’s a single dwelling, rented home or HMO.
LD1
The highest level of domestic coverage, with detection installed in most areas where a fire could start.
LD2
Detection in escape routes, plus higher-risk rooms such as kitchens and living rooms.
LD3
Minimum life protection, normally covering escape routes such as halls, landings and stairways.
We work with landlords, estate agents and property managers across London. We can help arrange alarm installation for single rental properties, HMOs, managed blocks, commercial premises and property portfolios — plus related fire safety services including fire risk assessments, fire door checks, emergency lighting checks and fire extinguisher checks.
Not every property needs the same type of fire alarm system. The right installation depends on the building layout, number of floors, occupancy risk and whether the property is domestic, HMO, communal or commercial. We can help arrange smoke alarms, heat alarms, CO alarms, interlinked alarms, mains-powered alarms and commercial fire alarm systems where required.
