Do you have to pay a monthly fee for a burglar alarm?

A monthly fee is a common assumption, but it only applies to certain types of system. The figures below are typical UK ranges for guidance, not quotations.

Systems with no monthly fee

Plenty of UK burglar alarms run with no subscription at all. The most common is the bell-only (audible-only) system: when a PIR or door contact triggers it, the external bell box and internal sounder go off, deterring intruders and alerting anyone nearby. There is no connection to an alarm receiving centre, so there is nothing to pay monthly — the only running cost is the occasional service and, on wireless systems, replacing sensor batteries. For a visible deterrent on a usually-occupied home, this is a genuinely fee-free option.

The other no-fee route is a self-monitored smart alarm. These systems send push notifications straight to your phone when a sensor triggers, letting you check a camera, call a neighbour or contact the police yourself. Because there is no ARC involved, there is usually no monthly charge, though some brands sell optional cloud video storage for cameras as a paid extra. For someone happy to be their own responder, a self-monitored smart kit combines app convenience with zero subscription.

It helps to separate the two reasons a fee might appear: the service and the maintenance. A bell-only or self-monitored alarm needs neither to function — it sounds or alerts on its own — so it can run for years with no recurring charge beyond batteries and the occasional optional service. The moment you want a third party involved, whether an alarm receiving centre handling activations or an approved company maintaining a graded system, a recurring cost appears. Understanding which of these you actually want is the clearest way to predict whether your alarm will carry an ongoing fee.

It helps to separate the one-off costs from the optional recurring ones. Buying and fitting the alarm is a capital cost you pay once; after that, a bell-only or self-monitored system can run for years with nothing more than the occasional sensor battery. The monthly fees only appear when you add a service on top — professional monitoring by an ARC, or a maintenance contract that keeps a graded system compliant. Seeing the fee as the price of a specific service, rather than an unavoidable cost of owning an alarm, is the clearest way to decide whether you need it.

When a monthly fee applies

A monthly fee enters the picture when you want the alarm to do something on your behalf when you are not there. Professional monitoring connects the panel to a 24-hour ARC that handles activations, contacting your keyholders and, for confirmed alarms with a URN, requesting police response. That service is what the subscription pays for, typically £10–£35 a month depending on whether it is keyholder or police-response level. It is the trade-off for a system that acts even when your phone is off or you are away.

The other recurring charge is a maintenance contract. This is usually annual rather than monthly, but it is a real ongoing cost for monitored or graded systems — and often a requirement, since a police URN depends on the alarm being maintained by an approved company. So a fully monitored, police-responding system tends to carry two recurring costs: the monitoring subscription and the maintenance contract. A bell-only system avoids both, which is precisely why it is the lower-running-cost choice.

It is also worth noting that some providers bundle the alarm hardware into a monthly package rather than charging an upfront install price, which spreads the cost but commits you to a contract. These deals can look like a low monthly figure but tie monitoring, maintenance and the equipment together over a fixed term. There is nothing wrong with the model, but it is a different proposition from owning a bell-only alarm outright with no fee, so reading whether a monthly figure buys a service, the hardware, or both is the key to comparing options fairly.

Where a monthly fee does apply, it usually buys one of two things. A monitoring subscription pays for the alarm receiving centre to handle every activation around the clock and, on a police-response system, to request police attendance. A maintenance contract pays for the annual service and call-outs that keep a graded install working and, on a monitored system, keep the URN valid. A monitored, police-responding alarm typically needs both, which is why its running cost is higher than a simple bell-only box — you are paying for an ongoing service, not just the hardware.

Choosing whether to pay

The decision is really about how much you want the alarm to act for you. If your priority is a visible deterrent and you are usually home or have neighbours who would respond, a bell-only or self-monitored system gives you that with no monthly fee. This is a perfectly sound choice for many homes and keeps the lifetime cost to the hardware plus the odd service.

If the home is regularly empty, holds valuable contents, or you want police response, then professional monitoring — and the fee that comes with it — earns its place. The subscription buys a 24-hour human service following an agreed escalation, and the police-response tier can summon attendance for confirmed alarms in a way no fee-free system can. The honest summary is that the monthly fee is optional but meaningful: skip it for a deterrent, pay it when you want the alarm to respond on your behalf.

There is also a sensible middle ground worth knowing about. Some systems let you run free app self-monitoring day to day and switch on a paid monitoring tier only when you need it — for a long holiday or a period the home will be empty. This means the monthly fee is not an all-or-nothing commitment: you keep the running cost at zero most of the time and add an independent 24-hour responder when the stakes are higher. For owners weighing cost against cover, that flexibility can be the practical answer rather than choosing one model permanently.
