Burglar Alarms: DIY vs. professional installation

Posted by Robin Knox on Mar 4, 2019 5:16:04 PM

When buying a burglar alarm many homeowners instinctively choose a DIY installation because it's free. They overlook the benefits of a professionally installation and, sometimes, live to regret it. We've taken a thorough look at the pros and cons of installing it yourself vs hiring a professional.


Pros of a DIY installation 

It’s Free

There are many benefits of a DIY installation, but perhaps the most attractive is that it doesn’t cost anything. You don’t pay for an installer to fit your alarm, and after purchasing, batteries and servicing is the only ongoing expenditure.

You can install it in your own time

A self-install alarm is also more convenient: you can install it in your own time. There’s no need find a day when the installer is free and you can stay home.

You learn how it works

Self-install alarms give you the opportunity to learn all about the system you’ve just bought, from the setup and components to which rooms should have sensors. This gives you the confidence to tackle any malfunctions or alarm-related anomalies in the future.

Cons of a DIY installation 

Monitoring by an ARC won’t be possible

The major drawback is that it won't be eligible for monitoring with a police response. Regulations state that in order for any alarm to be rigged up to the emergency services it must be installed by a qualified engineer. If you install it yourself then only you and nominated keyholders will be notified by the App. If you’d like to know more, here’s our blog on Self-Monitored vs Monitored alarms.

You might not install it properly

While the DIY option may sound easy, it can be trickier than expected. You need to make sure you know where sensors should be placed in order to be effective while ensuring they won’t constantly trigger false alarms. And if you have no tools and little DIY experience, tasks like drilling the external warning device to the wall could prove to be a headache.

Choice of alarm

Many dedicated alarm systems need to be professionally installed. These tend to meet UK and European industry standards in physical robustness, tamper proofing, environmental impact, false alarm reduction and sensor reliability.

DIY options are usually off-the-shelf kits that do more than just security. Often advertised as smart hubs rather than smart alarms, they’re lifestyle devices with security. While the versatility of these is great, they may not offer the same reliability and security.

Boundary will be in the fairly unique position of offering a dedicated smart intruder alarm, which can be DIY installed or professionally installed and conform to EN50131 Grade 2.

Pros of a Professional installation 

ARC Monitoring becomes an option

Perhaps the top advantage of professional installation is that your system will be eligible for monitoring. Your alarm is monitored by an alarm receiving centre, staffed by security personnel who will contact you, a nominated keyholder or the police in the event of a break-in. This is a massive stress reliever if you’re away from home a lot or you tend to keep your phone on silent.

A professional installs it

There’s also the convenience of having a pro else install your system, and the peace of mind of knowing that the alarm is fitted properly. Having a professionally installed alarm can significantly reduce the risk of false alarms being triggered easily.

Professional Know-how

Understanding how your alarm works is one thing, but understanding what happens when someone breaks-in is another. The professional installer can answer questions around monitoring, police response, avoiding false alarms and more!

Cons of a Professional installation 


Systems that require specialist installations are expensive, potentially around £200 for the installer’s time.


Then there’s your own time as you are the you need to make sure you are at home when the installation takes place.

Ongoing costs

Any ongoing maintenance or technical faults will need to be looked at by a professional. Some installers offer a 12 month guarantee, others will charge you to fix it.

What Boundary Offers

With Boundary Intruder Alarm, you'll have the option to choose of a DIY or professional installation with the standalone system. If you take choose a package with keyholder or police monitoring, a professional installation will be required to ensure the system is installed correctly and  false alarms are kept to a minimum.
