A standard bells-only alarm starts at £500 in London versus £310 in Scotland (Highlands & North) — a £190 gap.

What sets the price for burglar alarm installation?
The three main options homeowners typically choose from — and how they change the total:
- Bells-only alarm. A wireless audible-deterrent system — sensors, control panel and an external sounder, no monitoring. £500-£800 fitted by an accredited installer.
- Monitored alarm. An NSI/SSAIB system linked to a 24/7 Alarm Receiving Centre with keyholder or police response. £750-£1,300 fitted plus £15-£40 a month monitoring.
- Smart alarm + CCTV. App-controlled smart alarm combined with CCTV cameras and security lighting for full property coverage. £1,200-£2,500+ fitted depending on the number of cameras and zones.
Alarm installation in London and the South East runs 20-30% above the UK average.
Why does burglar alarm installation cost more in London?
The +61% London premium on a standard bells-only alarm tracks the same four factors seen across BestBuilders' full 2026 dataset, matching the pattern in RICS BCIS and FMB benchmark data:
- Labour rates. Skilled-trade day rates in London and the South East run 25–40% above the national average, the single biggest factor on a labour-heavy job.
- Demand and backlogs. High demand and long waiting lists let installers in the South East price higher; quieter regional markets are more competitive.
- Access and logistics. Restricted parking, skip and scaffold permits, congestion charges and tight rear access add cost in dense urban areas.
- Property type. London's older housing stock often needs more preparation or bespoke solutions than newer regional housing, which pushes labour hours up.
The takeaway for homeowners: the regional figure is a starting point, not a quote. The spread within a region — between the cheapest and most expensive installer — is often as wide as the gap between regions, which is why comparing three quotes matters more than any headline average.
