Smoke alarm installation cost

Nowadays there’s a range of fire alarm systems available at different prices and with varying features. To make things simple, we’ve laid out the average smoke detector installation cost for the different models available.

Battery-powered smoke alarm installation cost

Average battery-powered fire alarm system installation cost: £50

These are the most popular fire alarm systems for homeowners – commonly know as ‘smoke detectors’. They’re very easy to install and the cheapest option for your home.

You can connect different battery-powered detectors together so that when one is activated it will then set off others in a ‘daisy chain’ effect. This is particularly recommended in larger properties to ensure maximum safety.

The major downside of battery-powered fire alarm systems is that they’re completely dependent on the battery. If the battery dies then the system stops working, so it’s crucial to test them regularly.Fire alarm installation

Mains powered smoke alarm installation cost

Average wired fire alarm system installation cost: £200

A wired smoke alarm is a more robust system than the battery-powered option, as it is powered by the main electricity but also features a backup battery power supply.

Similar to battery-powered alarms, they can also be connected together to all sound when one of the detectors is activated.

App-enabled smoke alarm systems

Average app-enable fire alarm system installation cost: £250

The most modern version of a smoke alarm, this system will send a message straight to your phone so you’re immediately aware of a detector being activated.

Through the app, you can also turn the alarm off if you know it’s not a real fire or serious incident. And if you’re a real tech fan you can even connect the smoke alarm to a home camera system, such as Nest, for ultimate peace of mind.

Grade A fire alarm system cost

Average cost of a grade A fire alarm system: £2,500

In 2019, the British standard revised the fire alarm grading system and recommendations for fire alarm systems in domestic homes. Grade A is the most comprehensive type of fire alarm system available.

Grade A fire alarm systems have separate detectors, sounders and central control with indicating equipment and a backup power supply, e.g. battery back-up.

Commercial fire alarm system costs

Commercial fire alarm systems by their nature are more complex and expensive systems to install. They generally cover much larger spaces and involve more zones than a domestic fire alarm system, as such the prices will often vary considerably.

An average commercial fire alarm system installation will cost around £4,000 for materials and labour, which includes 8 zones and 20 detectors.

Other elements that you might need to consider are:

  • Magnetic door release and door holding devices – £200 (materials and labour)
  • Manual call points/break glass points – £150 each

As you can see, the cost of smoke alarm installation varies depending on the make, model and setting in which you need it fitted. Further, the price will usually be affected by your location, with costs in London skewing higher.

Do I need to install a fire alarm system?Fire alarm system being installed

If you’re responsible for a business property then you are required by law to have a fully functioning fire alarm system in place. Also, if you’re a landlord then you are also required to have a smoke detector system in place.

For your own home, it’s not a legal requirement to have a fire alarm system, but it is strongly recommended for the safety of you and your family.

A fire alarm is invaluable as it:

  • Provides early warning of a potential fire
  • Gives occupants of a building time to escape in the event of a fire
  • Can reduce the extent of fire damage through early warning, in the event of a fire.

How long does it take to install a fire alarm system?

The time it takes to install your fire alarm system will depend on the type of system you choose, as some are much more complex than others.

On average it can range from two hours to more than one day.

Can I install my own fire alarm system?

If you’re installing a battery-powered alarm system then you should be able to easily and quickly do the job yourself. For any of the wired alarm systems, we would recommend hiring a local fire alarm expert to carry out the installation. That way you know it’s installed safely and securely.
