The short answer
Yes — many UK burglar alarms let you self-monitor with a phone app. When a sensor triggers, the system sends a push notification straight to your phone, and you can arm or disarm the alarm remotely, check status, and view any connected cameras. Self-monitoring usually has no monthly fee, though some cameras need a paid cloud storage plan. The limitation is that it relies entirely on you noticing and acting on the alert — and it cannot summon police response, which requires a graded, professionally monitored system with a URN. App self-monitoring is a fee-free deterrent and awareness tool, not a substitute for an alarm receiving centre. This describes the standard UK position.
Self-monitoring via an app is popular and cheap, but it works differently from a professionally monitored system. The points below explain what it does and where its limits are.

How app self-monitoring works
App-based self-monitoring puts you in the role the alarm receiving centre would otherwise fill. The system connects to your home broadband (and often a mobile/GSM backup) and links to a smartphone app. When a PIR or door contact triggers, the panel sends a push notification to your phone within seconds, telling you which sensor activated. From the same app you can usually arm and disarm the system remotely, check whether it is set, review a recent event log, and — if you have connected cameras or a video doorbell — look at a live or recorded feed to see what caused the alert.
This gives you real, immediate awareness and a degree of control wherever you have a phone signal. You can disarm for a cleaner arriving, confirm the family is home safely, or check a notification while at work. For many households the combination of a visible alarm, instant alerts and remote control covers the practical needs of home security at no recurring cost beyond the hardware and the occasional sensor battery.
The arming options an app provides are part of its everyday usefulness. Most self-monitored systems let you set the alarm to full arm when leaving, part arm at night so downstairs sensors are active while you sleep upstairs, and disarm remotely for someone arriving. The app typically shows an event log of arming, disarming and activations, so you can see who set or unset the system and when. This visibility and control, available from anywhere with a signal, is a genuine convenience that a traditional keypad-only alarm does not offer, and it is a large part of why self-monitored smart systems are popular.

How app self-monitoring compares with a monitored service.
What it costs and what to watch for
The headline appeal of app self-monitoring is that the alerts themselves are free — there is no alarm receiving centre to pay. The recurring costs, where they exist, come from extras. The most common is cloud video storage: many camera and doorbell systems give you live viewing for nothing but charge a monthly fee to retain recorded footage beyond a day or two. If evidence after an event matters to you, factor that subscription in, because a 'free' camera with no retained recordings is of limited use after the fact.
Wireless systems also carry the small, ongoing cost of sensor batteries, which the app will warn you about before they fail. Beyond that, the things to watch are practical rather than financial: app self-monitoring depends on a working internet connection and on your phone being on, charged and in signal. A broadband outage, a flat phone or being abroad without data all blunt its effectiveness, which is the trade-off for avoiding a subscription.
Connectivity is the quiet dependency behind app self-monitoring. The whole model rests on the panel reaching the internet and your phone receiving the alert, so a broadband outage, a router failure or simply leaving your phone on silent can blunt it. Better systems add a mobile/GSM backup so the panel can still notify you if broadband drops, but the alert still has to find you. This is the structural difference from professional monitoring: an ARC is staffed continuously and does not depend on your attention, whereas self-monitoring is only as reliable as the connection and the person at the other end.
What app monitoring cannot do
The most important limitation is police response. An app-monitored alarm cannot summon police, because police attendance through the national scheme requires a graded system installed and maintained by an NSI or SSAIB approved company, confirmed-activation signalling, and a URN. A self-monitored kit has none of these, so even if you see the alert and call 999 yourself, you are reporting a possible crime as a member of the public, not triggering the prioritised confirmed-alarm response a URN provides.
The second limitation is the reliance on you. A professionally monitored system has an ARC that acts 24 hours a day regardless of whether you are aware, escalating to keyholders and police as agreed. App self-monitoring removes that safety net: if you miss the notification, nothing else happens. For a usually-occupied, lower-risk home this is often an acceptable trade for zero subscription. For a home that is regularly empty or holds high-value contents, the absence of an independent responder is the reason many owners still choose professional monitoring despite the cost.
There is also a sensible middle path worth knowing about. Some systems let you self-monitor for free day to day but add professional monitoring as an optional paid tier, either permanently or for periods such as a long holiday. This means you are not locked into one model: you can run on free app alerts most of the time and switch on an alarm receiving centre when the home will be empty for a stretch. For owners weighing cost against cover, this flexibility can be the practical answer — keeping the running cost low while retaining the option of a full monitored response when it matters most.
It is also worth being realistic about what you would actually do with an alert while away. Self-monitoring is most useful when you can act on it — call a neighbour, check a camera, decide whether to ring the police — and least useful when you are unreachable or too far to help. Pairing the app with a trusted local contact who can attend, and with cameras that let you verify a trigger, closes much of that gap without a subscription. But the responsibility still rests with you, which is the defining difference from a professionally monitored system that responds whether or not you are paying attention.
Frequently asked questions
Does app self-monitoring cost anything?
The alerts themselves are usually free, with no monthly fee. Costs appear if you add cameras that need a cloud storage subscription to retain footage, and wireless systems need occasional sensor battery replacement. There is no alarm receiving centre fee.
Can a self-monitored app alarm call the police?
No. App self-monitoring cannot summon police response. That requires a graded system from an NSI or SSAIB approved company with confirmed-activation signalling and a URN. If you see an alert you can call the police yourself, but as a member of the public, not via a prioritised confirmed alarm.
What happens if I miss the app notification?
Nothing automatic. App self-monitoring relies entirely on you noticing and acting, so a missed notification means no further response. A professionally monitored system avoids this by having an alarm receiving centre that escalates to keyholders and police regardless of whether you are aware.
