How much does a burglar alarm cost in the UK?
There is no single price for a burglar alarm. The cost depends on the size of your property, whether the system is wired or wireless, how many sensors it needs, and whether you take annual servicing. Locks & Alarms Ltd quotes each job after a free visit, so the figure reflects your property rather than a market average.
What affects the price?
Four things set the cost of an alarm: the size and layout of the property, whether the system is wired or wireless, the number and type of sensors, and whether you take annual servicing. A flat with one door needs less equipment than a house with three entry points and a garage.
Sensor count is the biggest variable. One Checkatrade-verified Locks & Alarms Ltd job covered an Ajax alarm system with 15 glass-break protectors, PIRs and key fobs. Another home may need a control panel, two door contacts and one PIR. The equipment list is different for every property, so the price is too.
Ongoing choices matter as well. Annual alarm servicing with battery replacement is verified work in the firm’s Checkatrade history. Choosing a servicing plan changes the whole-life cost of the system, not just the day-one figure.
Why we quote after a visit, not from a price list
A price list assumes every property is the same. A quote visit does not. An engineer walks your entry points, counts the doors and windows that need cover, and recommends a system to match. The quote is then written for that property. Locks & Alarms Ltd quotes are free and carry no obligation.
Reviewers describe how this works. A Checkatrade reviewer in DA7 wrote that the engineers “talk through all our options” and worked with them to get the system they needed. The recommendation comes first; the price follows from it.
What is included in a quote?
You receive a written quote after the visit, with no obligation to accept it. A Checkatrade reviewer in DA17 wrote: “He sent through the quote quickly and the job was booked in”, and the installation then “went smoothly and completed on time”. The quote covers the recommended system and the work to fit it.
The estimate is meant to hold. A DA1 reviewer, describing an eight-channel recorder and five-camera CCTV installation, wrote that “the final bill was exactly as estimated”. Book your free quote to get a figure for your own property, then decide in your own time.
