How Much Does a House Alarm System Cost?

Burglar alarm systems for home installation, fitted by a professional, range in cost depending on a number of factors. We’ll explain what everything we’ve listed here means on this page:

Type of alarm Number of sensors/contacts Number of keyfobs Supply only cost Supply and install cost Monthly fees
Bell-only wireless 2 1 £69-£250 £169-£350 none
Bell-only wired 2/1 1 Not available £400 none

Auto-dialler alarm 1/1 1 £190-£310 £290-£410 none
Smart alarm 1 0 (your smartphone acts as keyfob) £159 £259 none

Which type of burglar alarm should I choose?

When people think of burglar alarms, ADT alarms often springs to mind. They are the market leader in burglar alarms for houses and have been for years. But are they the right company offering the right system for you?

Burglar alarms have evolved a lot since they first became popular additions to people’s homes in the 1980s and 1990s. At that time, sensors were sometimes a little too sensitive, and your burglar alarm might go off in the middle of the night for no reason at all. Wireless systems had a limited range, so if you had any outhouses, sheds, or other outside buildings that needed protecting, it was difficult to find a sensor that was powerful enough. Nowadays, burglar alarms are far more technologically advanced. We’ll cover everything you need to know on this page, including:

  • The benefits of burglar alarms
  • The difference between wired and wireless alarms
  • The different kinds of Monitored alarms
  • What are DIY alarms?
  • An explanation of how a burglar alarm works
  • Questions to ask your installer
  • Other frequently asked questions

What are the benefits of a Burglar Alarm?

The reasons for getting a burglar alarm installed have not changed:

  • Protect your home and all its possessions
  • Protect your family from harm
  • Notify your neighbours and the Police of a break-in
  • Protect yourself from confrontation

It doesn’t matter to most homeowners that the number of burglaries has been dropping. The fact is that it’s still happening. And you never know when it’s your household that’s drawn the short straw this time around.

The sad fact is that most people don’t think about having an alarm fitted to their home until after they have been the victim of a burglary. So, if you don’t have an alarm on your home just yet, or you want to replace your old system with a modern home security system, please read on.

Wired Burglar Alarms vs Wireless Burglar Alarms

The burglar alarm costs shown at the top of the page are for basic supply only and supply plus installation work.

Each of the types of systems listed is customisable. So, you can add extra sensors, extra contacts, and extra keyfobs for absolute convenience. You can also specify to a monitored alarm installer whether you want police response in the event of a triggered alarm. However, this normally costs extra at the time of installation.

What are wired burglar alarms?

With a wired burglar alarm system, everything, including the sensors, is hardwired into the mains. It means that you never have to worry about a battery running low. However, the installation prices are a lot higher because of the amount of wiring that needs to be run. Of course, this will increase your overall burglar alarm costs.

What are wireless burglar alarms?

More homeowners have wireless burglar alarms fitted than any other type of alarm. The main control panel is hooked up to the mains but the sensors are battery-powered. Because they use so little electricity, the batteries used in sensors tend to last for a long time – many, many years in some cases. If the battery in a sensor is beginning to run low, it will either:

  • Send a message back to the control panel
  • Continuously flash until you replace the battery

Monitored Burglar Alarms

Also known as a keyholder response alarm, you can choose to have your burglar alarm monitored. What that means is that, should something happen and the alarm is set off, your control panel will tell you or someone else.

What are bell-only alarms?

A system with no monitoring attached to it is called a “bell-only” alarm. It’s given that name because the only way it signals a disturbance is via the sound of the bell or siren from the box attached to the outside of your home.

For many years, British Telecom has run a system called BT RedCare. BT RedCare informs either the Police and/or named people you want to know that an alarm has been triggered. Police will generally respond. However, if there are too many false alarms, they have been known to refuse to attend.

What a monitored alarm can do has progressed a lot in recent years. You can now wire microphones up in your home so that, when the alarm is activated, a monitoring station can listen to what’s happening. Some companies will install speakers too, to challenge any intruder who has broken into your property.

What is an auto-dialler system?

You also have the option to select an “auto-dialler” system. When your alarm is triggered, the control panel uses either a fixed line or a mobile phone card to call someone you nominate to let them know that there has been an incident. For this to work, you need a landline phone connection, or you need to live in an area with good mobile phone reception.

What are smart alarms?

There is also a new type of monitoring linked to your mobile phone. These “smart alarms” contact you or someone you’ve nominated by smartphone if your burglar alarm goes off. Smart alarm systems typically show you live video from your home of the rooms where a break-in’s been detected. As with the “auto-dialler” system, you will need to make sure that your home gets a strong mobile phone signal before you invest in one of these alarm systems. Otherwise, you could end up with unnecessary burglar alarm costs.

DIY burglar alarms

Many people looking to install their burglar alarm system will go down to one of the major DIY chains to pick out a system. The hope here is that installing it themselves will keep their burglar alarm costs down. B&Q burglar alarms are a particular bestseller, although a wide range of alarm systems are now available online.

If you feel confident installing either a wired or wireless burglar alarm, you can do this for yourself. It will probably take about 6-8 hours. However, we urge you to please make sure that you are certain of what you’re doing when connecting the burglar alarm panel (or the sensors) to your mains electricity.

If you later decide that you want your alarm to be monitored, you’ll need to pre-plan. You’ll need to buy an alarm panel that allows a monitoring function to be added. If it doesn’t allow this, you will have to scrap your old alarm and replace it with a new one. This means you’ll have spent more on your burglar alarm costs overall. Speaking to an expert about all the options in advance and deciding on the best one for you could help to avoid unnecessary costs.

How do Burglar Alarms Work?

There are four main parts to your burglar alarm:

Burglar alarm control panel

The burglar alarm control panel is the box on the wall (usually positioned by the front door) that switches the system off and on. Burglar alarm control panels receive signals from all the sensors in your home. Because the sensors use slightly different frequencies, you can switch the alarm on in certain parts of your home (while leaving it off in others). Your alarm system will only be looking out for alerts from the sensors it’s monitoring.

Alarm sensors and contacts

Sensors are placed around your home which looks for movement in a room. They do this using Passive Infrared Detectors (PIRs). PIRs look for moving objects that give off body heat. When it detects them, and the burglar alarm is switched on, it will then go into emergency mode. In emergency mode, it will ring the bell box, contact the Police, send a text message, or do whatever it is you’ve requested to your installer.

You can also attach contacts to your doors and windows. If your alarm is switched on and someone tries to open a door or a window, the contact will detect this, and it will then trigger the alarm.

Wireless alarm keyfobs

Keyfobs look like the type of car keys you press to open and shut the doors. You can use them to switch your alarm on or off.

Alarm “bell box”

The bell boxes are attached to the outside of your home, generally at the front and the back. They show a burglar that an alarm protects your home. If your alarm system is triggered, it’s the bell box that makes the loud noise alerting people that something may be wrong. Although still called a bell box by many in the trade, it’s more usual now to have a siren sound than a clanging bell.

What questions should I ask a potential installer?

Before you commit to a system and to a company, it’s best to check with a potential installer that the system they propose to install really will do the job you want it to do.

What is the lead time?

You might want to ask for “lead time”. In other words: if you place an order for a system, how long will it be before you can install it? If you’ve signed up for a monitoring package, find out how long they take to respond to alarm activations. Most companies should be able to produce statistics from the last twelve months for you.

What if my pet keeps setting off my burglar alarm?

Another scenario: you’re installing pet-friendly PIRs and, after installation, your cat keeps waking up the whole household by jumping on a sideboard at 3 in the morning! What remedial action will the company take if they told you that your pet will never set off the alarm?

Will a burglar alarm system protect me?

On the subject of coverage, go through with an installer why they think that the layout of the sensors they propose is going to protect you.

Does your alarm installer have any accreditations?

On a business front, you might want to ask for testimonials from existing customers who live near you. Top tip – online reviews are great for finding reliable companies, so do your research before you commit.

Does your burglar alarm system come with a guarantee?

Despite the best intentions, even really good businesses cease trading so you should ask if the company provides an insurance-backed guarantee that your system will still be serviced and repaired by a professional if the company goes into liquidation.

Should my installer belong to a trade organisation?

There are three main trade bodies in the UK which burglar alarm companies can join. Those bodies are the Security Systems and Alarms Inspection Board, National Security Inspectorate, and the British Security Industry Association.

Membership of these bodies provides homeowners with peace of mind that, in the event of a dispute, there is an independent arbiter that can force the installer to put things right. Otherwise, the installer may be ejected from the membership. If they are thrown out, most business-to-business and insurance work will be denied to them, so continued membership is really important.

Your questions answered

How much does a burglar alarm cost?

A basic DIY burglar alarm will cost around £150. More sophisticated alarms can be priced upwards of £1,000, with additional monthly monitoring fees.

Is a burglar alarm a good investment?

Burglar alarms give you peace of mind and can mean that intruders are deterred from your property, saving you money. With a burglar alarm installed, your home or business insurance may become cheaper too.

What is a dialer burglar alarm?

In the event of a break-in or attempted break-in, a dialer burglar alarm dials a list of several numbers of your choice to alert them. This can also be used to raise the alarm in the event of a fire or other emergency.

How much does CCTV cost?

The price of CCTV can vary significantly depending on the sophistication of the system you choose. The cost can start as low as £20 and can run into hundreds of pounds.

Are monitored alarms worth the money?

Monitored alarms cost more than bell-only alarms and less than auto-dialler alarms initially. However, they have monthly fees to consider but give you peace of mind that professionals are monitoring your alarm at all times.

Can you install burglar alarms for sheds and other outbuildings?

If you store items in your shed or any other outbuilding that are valuable and personal to you, it would be terrible if you went to all of the trouble and expense of fitting a burglar alarm to your main home only to find that, if you were burgled, the thieves went for the shed or another outbuilding instead.

It is possible to connect PIRs to your home system from a distance. However, the further the building or shed you're trying to protect is from your home, the more difficult it gets. It would be wise to ask a professional installer for advice in these situations.

Are burglar alarms pet friendly?

If you have small pets in your home, ask your installer about pet-friendly PIRs. This is a clever system which monitors your room except for the first metre or so of height in the room from the floor. So if your cat is just wandering around your front room in the dead of night, the PIR sensor frequencies won't see them because they're too low down.

If you have a large pet or your small pet likes to jump on furniture, tables, breakfast bars, and so on, a pet-friendly PIR may not actually provide the solution you're hoping for. In these cases, it's better to go for a door or window contact instead of a PIR. Speak to an alarm expert to find out how much pet-friendly burglar alarms cost.

Do you need planning permission for a burglar alarm?

Burglar alarm installations (including the box on the outside of your home) are considered minor installations. This means they are not covered by planning regulations.

However, if you live in a listed building, in a conservation area, or your home is subject to an Article 4 Direction, then it's always advisable to contact someone from the planning department of your local council prior to committing any money. This ensures you don't spend out on any burglar alarm costs that could become unnecessary or unable to be installed in your home.
