If you’re thinking of changing from a wired to a wireless system or installing a burglar alarm from scratch, read our dedicated cost guide for home security installation.


cost of burglar alarm maintenanceHow often should I get my burglar alarm serviced?

A good rule of thumb is to test your systems every six months. At a minimum, get a professional to service your set up annually.

If your burglar alarm system is playing up, it’s worth getting it serviced right away. Putting this off could compromise your home’s security and leave your home vulnerable to break-ins.

For a small upfront cost, it’s worth it to protect those valuable possessions that would cost a fortune to replace.

Remember to collect quotes from different companies so you can find the best value pricing.

What should I consider when looking into burglar alarm maintenance costs?

To calculate the total burglar alarm service cost, take stock of how many sensors you have in your house. The more you have, the more will require servicing, and costs will rise accordingly.

Also, if you have sensors in hard-to-reach places, some tradespeople will charge extra where ladders or special equipment are required.

How often should I change my burglar alarm battery?

Aim to change your burglar alarm batteries every three to five years.

Most modern alarms come with a button which can test the life within your existing battery and inform you if it requires replacing. Replacing a burglar alarm battery is straightforward and should be done immediately to ensure you keep your house or property protected.

burglar alarm maintenance costsShould I switch from a wired to a wireless burglar alarm during a servicing?

If you are considering switching from a wired to a wireless burglar alarm, this will increase your burglar alarm service cost. Wired systems have lost popularity in recent years as wireless system installation is typically shorter.

Wireless alarm systems nowadays are tremendously practical if you are thinking about moving home or premises.

However, if your existing wired system works well and you are not thinking about moving anytime soon, you don’t have to change to a wireless system during a servicing.

Can I service my own burglar alarms?

If you have experience in the home security sector or are an experienced electrician, you can likely service your burglar alarms yourself to ensure sufficient function.

However, if you are not up to date with security tech or familiar with home electrics, servicing is best left to the professionals.
