What moves the price
- Number of alarms needed — each extra smoke or heat alarm adds a unit and fitting time, and interlinking more alarms takes longer.
- Mains-wired or battery — mains-wired interlinked alarms need cabling between rooms, which takes far longer than fitting battery alarms.
- New wiring or replacing — swapping old mains alarms for new ones on the same wiring is quicker than wiring fresh alarm points.
- Ceiling access — alarms in high hallways, or in ceilings with no attic space above, take longer to wire.

How to pay less
- Replacing old mains alarms with new ones on the existing wiring costs less than wiring new alarm points.
- Radio-interlinked alarms can link rooms without new cable, which can cost less than hard-wiring them together.
- Having every smoke and heat alarm in the house fitted in one visit costs less than separate call-outs.
- Fitting battery smoke alarms yourself, where wiring is not needed, avoids paying for an installation visit.
- Testing your alarms yourself each month and vacuuming the vents keeps them working and avoids paying for maintenance checks.
Before you book
- Access to all areas where alarms will be installed.
- Information on the layout of your home and any specific safety concerns.
- Details about existing alarms, including their type and age, if applicable.
- You can ask the installer whether they fit mains-wired and interlinked smoke alarms regularly.
- Tell the installer which rooms have a cooker, stove or open fire, as a heat alarm suits a kitchen better than a smoke alarm.
- Agree whether the price includes the alarms themselves and taking away the old ones.
