If you already have a burglar alarm installed, you’re doing the right thing to protect your home. But like any system you rely on, it still needs regular care. Burglar alarm servicing and maintenance make sure everything works properly, stays insurance-compliant, and doesn’t let you down when you need it most.
Think of it like a yearly MOT for your alarm - quick, sensible, and reassuring. Let’s walk through why servicing matters, when an upgrade makes sense, and how we keep things simple and pressure-free.

Why Regular Servicing Keeps Your Alarm In Top Shape
Regular alarm servicing and maintenance help spot wear, battery issues and sensor faults before they cause false alarms or system failures. Over time, parts of your system can start to wear out, get dusty, or just go a bit wonky. Sensors might not be as sharp. Batteries can lose their oomph. Technology moves on.
By booking an annual service, you’ll:
Catch small faults before they become big problems
Make sure your sirens and sensors are working properly
Keep your system insurance compliant
Avoid unexpected breakdowns when you need it most
It’s one of those little jobs that can make a big difference down the line - like checking your tyres before a long drive. Quick to do, but reassuring once it’s done.
How Often Should A Burglar Alarm Be Serviced?
Most burglar alarms should be serviced once a year.
Annual alarm servicing helps to:
Keep your system reliable and responsive
Ensure batteries are holding charge properly
Check sensors are triggering correctly
Maintain insurance compliance
Reduce the risk of faults while you’re away on holiday
If your alarm is older, has wireless components, or hasn’t been checked in a while, regular maintenance becomes even more important. A short yearly visit can prevent the exact problems we often get called out for - alarms failing just before trips, power cuts, or busy periods.

Is It Time For An Upgrade? Here’s Why It Might Be
If your system’s more than a few years old, you could be missing out on features that make life easier and your home safer.
Here are a few signs you might benefit from an upgrade:
Your bell box looks faded or doesn’t light up at night
You don’t have an app to check your alarm when you're out
The keypad’s fiddly or hard to read
You’re still relying on wired-only tech
Upgrading doesn't mean starting from scratch. We can usually reconnect your existing detectors and just enhance the brains and bells of the system. Nice and simple.
What We Check During An Alarm Service
When you book a burglar alarm service with MAS, we’ll:
Test all sensors and detectors to make sure they’re working as they should
Check internal and external sounders
Assess the condition of your backup battery
Clean any components that need a bit of attention
And once we’re done? You’ll get a 12-month alarm service warranty covering parts and labour - so if anything goes wrong, we’ll sort it. ... More About Those Batteries
Every burglar alarm system has a backup battery in case the power goes out. These are designed to last about 12 hours when fully charged - but after 3 years or so, they can start to lose performance.
As part of your house alarm service and maintenance, we’ll:
Test your backup battery and provide battery replacements it if needed
Check any detector batteries (especially in wireless or hybrid systems)
Top tip: syncing battery replacement with your security alarm service call saves time and keeps your home protected.
How Long Does A Burglar Alarm Service Take & How Often Should You Book?
A standard burglar alarm service takes anywhere from 30 minutes to an hour or so. If a battery needs changing, it might take a little longer - but we’ll let you know what’s needed before we start.
We recommend getting your house alarm system serviced once a year. That way, everything stays in tip-top shape and you can relax knowing your home security alarm is all working quietly in the background.

What’s In Our Upgrade Package?
If you decide to upgrade your burglar alarm system, here’s what we typically include:
A modern LED-lit bell box for better visibility and a stronger deterrent
An intuitive touchscreen keypad that’s easy to use

A reliable 12-volt backup battery
Reconnection of any working detectors you already have
A discounted GSM/Wi-Fi communicator for improved remote access

It’s a solid house alarm upgrade without ripping out everything you’ve already got.

FAQs
How often should I get my alarm serviced?
Once a year is usually enough to keep your system running reliably. Annual servicing helps spot small issues early and ensures everything works properly when you need it.
Is burglar alarm servicing really necessary?
Yes. Even if your alarm seems fine, regular servicing helps catch hidden issues like weak batteries, sensor faults or communication problems. It also helps keep your system insurance-compliant and reliable.
What happens during a burglar alarm service?
During a service, we test all sensors, check the control panel and bell box, inspect batteries, and make sure the system is communicating correctly. We’ll also clean components if needed and flag anything that may need attention.
What happens if I don’t service my alarm?
Without regular servicing, alarms are more likely to suffer from battery failures, false alarms, or sensors not triggering correctly. Many faults only show up during power cuts or when the system is under stress.
How long do alarm batteries last?
Most backup batteries last around 3–5 years. As part of a service, we test battery performance and replace them if needed to avoid unexpected failures.
Do I need a whole new system to get remote access?
Not at all. In many cases, we can upgrade just the control panel and add a GSM or Wi-Fi communicator to enable app access without replacing the full system.
Will you reconnect my existing detectors during an upgrade?
Yes. As long as your existing detectors are working properly, we’ll keep them in place and reconnect them to your upgraded system.
Do I need to be home during the service?
Yes. We’ll need access to your control panel, sensors and bell box. Most services take around 30–60 minutes, and we’ll be in and out with minimal disruption.
