The short answer
Installing a mains-powered, interlinked smoke and heat alarm system in a typical Manchester home costs around £300–£700 depending on the number of alarms and cabling. Small commercial fire alarm systems are priced per site based on the number of zones, detectors and the panel required.
Whether you need a few interlinked domestic alarms or a small commercial system, the cost comes down to how many devices are needed and how much cabling is involved.
Typical domestic costs
For a home system of mains-powered, interlinked alarms (so when one sounds, they all do):
- Standard three-bed, three to four interlinked alarms: £300–£500
- Larger home or more detectors: £500–£700+
- Wireless-interlinked alarms where cabling is difficult: priced per job
Commercial systems
Small business fire alarm systems (shops, offices, salons) are designed to the relevant standard and priced on the number of zones and detectors plus the control panel. These usually also need a service and maintenance arrangement to stay compliant.
