What Does Centrally Monitored Mean for a Home Insurance Discount?
It means your alarm system connects to a monitoring company that alerts police or fire automatically, not just a loud siren.
Free to compare
A siren alone, without a company watching for it, usually doesn't qualify. The discount shows up because a monitored system cuts the insurer's risk of a total loss from fire or an uncaught break-in, so they price for it. To get credit, the system typically needs to be professionally installed and actively monitored under a contract, not a DIY setup with an app alert only. Check your declarations page for a protective device credit, and if your renewal went up without the discount changing, the increase is coming from somewhere else, not this.
Worth checking against other insurers
If your system qualifies and the discount isn't on your declarations page, that's worth fixing. If it already is and your renewal still rose, another insurer may still price the risk lower.
What kind of monitoring actually counts
Insurers usually want to see a few specific things before they apply the credit. The system should cover entry points and motion inside the house, not just a single door sensor. It needs to connect to a monitoring center that contacts police, fire, or both when it triggers, and that center needs to operate every hour of every day. A camera system that sends a notification to your phone doesn't meet that bar on its own, even if it also sounds an alarm, because no one is dispatched unless you act on the alert yourself.
The difference between self-monitored and professionally monitored is where most people get tripped up. Self-monitored means you get the alert and decide what to do, maybe you call 911, maybe you're asleep and don't see it for an hour. Professionally monitored means a company is watching for the signal and calls emergency services the moment it comes in, whether or not you ever see your phone. Insurers price the second one lower because the gap between damage starting and someone responding to it is shorter and more reliable.
Fire monitoring and burglar monitoring are usually treated as separate things on the application, and some insurers ask about each one. A system that monitors for smoke and heat can qualify for a credit even if it has no burglar alarm component, and the reverse is also true. If your system does both, say so when asked. If it only does one, it may still be worth something, just possibly a smaller discount than a full system would bring.
Most insurers also want some proof the system is real and active, not something installed years ago and since disconnected. That might mean a monitoring company's name and account number, a copy of the service contract, or a certificate the alarm company provides for insurance purposes. If you installed a system recently or switched monitoring providers, that documentation is usually what triggers the insurer to add or update the credit, so it's worth asking the alarm company for it directly instead of assuming the insurer already knows.
Does a video doorbell or smart lock count toward this
Smart home devices get lumped in with alarm systems in people's minds, but insurers draw a clear line. A video doorbell records and alerts, a smart lock tracks who comes and goes, a smart smoke detector pings your phone when it senses smoke. None of them call anyone on your behalf. They're useful for your own awareness and sometimes for a claim after the fact, since footage can help establish what happened, but they don't reduce the insurer's risk the way a monitored alarm does, so they typically don't carry a discount on their own.
Where these devices sometimes matter is as an add-on to a system that already qualifies. If a monitored alarm covers the doors and motion sensors, and a video doorbell sits on top of that, some insurers note the extra layer favorably, though it rarely moves the discount by itself. A smart smoke detector connected to a monitored fire system is different from one that just texts you, even if they look the same on the box. The connection to a monitoring center is what the insurer is pricing, not the presence of a smart device.
Water sensors are a separate case worth knowing about. A sensor that detects a leak and shuts off the water supply automatically, without anyone needing to act, is sometimes eligible for its own credit, apart from anything related to fire or burglar monitoring. That one isn't about intrusion or fire risk, it's about catching a slow leak before it turns into a much larger water damage claim, so insurers treat it as its own category on the application.
If the house has a mix of devices and it's not clear what qualifies, the cleanest approach is to list everything installed, including the monitoring company name if there is one, and let the insurer say which parts apply to pricing. Guessing which device counts and leaving others off the application usually means leaving a discount unclaimed, since insurers don't go looking for devices you didn't mention.
Before you renew
Pull your declarations page and look for a protective device credit next to your alarm system. If it's missing and your system is professionally monitored, that's worth raising before comparing other insurers.
