How much does it cost to install a burglar alarm?

Installation is rarely quoted on its own — it sits inside the system price — but the labour element is a real and variable part of the cost. The figures below are typical UK ranges for guidance, not quotations.

How installation labour is priced

Most installers quote a single all-in figure for supply and fit rather than splitting out labour, because the two are closely linked: the same engineer who surveys the property positions and commissions the equipment. Where labour is broken out, it reflects the time on site — commonly half a day for a small system and a full day for a larger one — plus the survey beforehand. The survey is not a formality; it decides where PIRs go to give clean coverage without blind spots or false triggers, where door contacts sit, and where the external bell box is mounted to be visible yet hard to reach.

Commissioning is the part that turns fitted hardware into a working alarm. The engineer walk-tests every sensor, sets the entry and exit timers so you can leave and return without false alarms, programs the keypad and any keyfobs, and configures the bell box and any signalling. On a graded system they also confirm tamper protection and, for a monitored install, that the panel reports correctly to the alarm receiving centre. A rushed commissioning is a common cause of nuisance false alarms later, which is why the labour element is worth as much as the hardware.

The survey also shapes cost in ways that are easy to overlook. A good engineer plans the system to give overlapping but non-conflicting coverage: PIRs angled to sweep a room without staring at a radiator or a sunlit window that could cause false triggers, door contacts aligned so a slightly warped door still reads as closed, and the bell box positioned high and visible yet out of easy reach. Getting this right at survey stage is what prevents the nuisance activations that otherwise generate call-outs later, so the time spent planning is part of the value, not an overhead.

The size and layout of the property drive the hours as much as the day rate. A compact flat with the panel near the entry point and a clear cable route is a quick job; a period house with thick walls, no loft access and a detached garage to cover takes far longer, because every awkward cable run or extra detector adds time. Installers also factor in commissioning — walk-testing every sensor, setting entry/exit timers, programming the keypad and, on a monitored system, registering the signalling path with the ARC. That careful sign-off is part of why a proper install is not simply the cost of the parts.

Why wired and wireless installs cost differently

The single biggest variable in installation cost is whether the system is wired or wireless. A wired alarm connects every sensor back to the control panel with cable, which in an occupied, finished home means routing through lofts, under floors and inside walls, with some making-good afterwards. That labour adds hours and is the reason wired retrofits cost more to install than wireless ones. In a new-build or a property being renovated, by contrast, wiring can be run before walls are closed up, making wired both neat and economical.

A wireless system uses battery-powered sensors that communicate with the panel by radio, so there is little or no cabling to chase in. Fitting is faster and tidier, which lowers the labour element, but the trade-off is ongoing battery replacement and slightly higher per-device hardware cost. For most existing homes, wireless is the quicker and less disruptive option, while wired suits properties where the structure is open or where a hard-wired, mains-powered approach is preferred.

Wireless kit shifts the balance from labour to hardware. Because there is little or no cabling, the on-site time can be a few hours rather than a couple of days, which suits occupied homes and rented property where chasing cables into walls is unwelcome. The trade-off is that each wireless detector contains its own radio and battery, so the components cost more and will need periodic battery replacement — a small recurring task the panel flags in advance. For a new-build or a major renovation where walls are already open, a wired install is often the more economical and maintenance-light choice over the system's life.

Approved installers and certification

Who fits the alarm affects both cost and what the system can do. An installation by an NSI (National Security Inspectorate) or SSAIB approved company is carried out to a recognised standard, typically EN 50131, and comes with a certificate, a maintenance regime and the ability to apply for a police Unique Reference Number (URN). This costs more than a basic uncertified fit, but it is what allows the system to qualify for police response and what insurers may require for higher-value homes.

An uncertified install — including most self-fit DIY kits — is cheaper and perfectly serviceable as an audible deterrent, but it generally cannot obtain police response and may not satisfy an insurer who specifies a maintained, graded system. The right choice depends on the property and on whether monitoring or police response is wanted: for a straightforward bell-only deterrent, a competent general install is fine; for a monitored, police-responding alarm, an approved installer is effectively required.

One further point on labour: the make and architecture of the system affects fitting time. A panel that supports plug-and-play wireless devices and guided commissioning is quicker to set up than one requiring manual addressing of each sensor, and a system designed for confirmed-activation signalling needs additional programming so that two independent triggers are required before a confirmed alarm is reported. These are not hidden extras so much as the reason a graded, monitored install takes longer to commission than a basic bell-only one — the engineer is configuring the logic that makes police response and false-alarm filtering work, not just hanging sensors on walls.

Certification is where an approved install earns its keep. A system fitted by an NSI or SSAIB approved company to EN 50131 comes with documentation an insurer recognises and, where specified, qualifies for a police URN. A general electrician may fit a working alarm for less, but without that third-party certification it will not satisfy an insurance condition that names an approved, maintained, graded system, and it cannot obtain police response. For anyone whose cover or risk profile demands compliance, the certified route is not an upsell but a requirement, and that is reflected in the quote.
