How Much Does It Cost to Have a Burglar Alarm Fitted?

Honest pricing guide

Asking for a single figure on burglar alarm installation cost rarely gets a useful answer, because a two bedroom flat with four sensors and a one door bell box is a different job to a detached house needing eight zones, an outbuilding and app control on a phone. Typical UK market pricing in 2026 for a straightforward wireless system with app access tends to sit in a few hundred pounds up to around a thousand for a small to medium home, with larger or more complex jobs running higher.

The biggest single factor is whether the system is wired or wireless. Wireless kits, using 868MHz sensors talking back to the panel, avoid running cable through walls and ceilings, which keeps labour down but the hardware itself often costs a little more per zone. Wired systems using Cat6 or dedicated alarm cable are usually cheaper in parts but take longer to first fix, especially in a house that is already decorated rather than mid build.

The other big swing is bell only versus app enabled. A bell only system, which simply sounds locally and flashes the bell box, is the cheapest way to add a visible deterrent. Adding a SIM or WiFi communicator so you get phone notifications and remote arming pushes the price up, as does every extra zone, keypad or smoke style detector you add to the design.
