How much does fire alarm system installation cost?

Fire can cause severe property damage. Worse, it may injure persons and claim lives. Compared to natural disasters, you can prepare for fire incidents. Since fire burns and spreads very swiftly, installing preventive measures such as fire extinguishers, smoke detectors, and heat detectors can help minimise damage. The overall building structure and a fire exit can also maximise the safety of the people who live or spend time in the building. And if you own a commercial or office building, there are fire safety mandates you must comply with according to local building regulations.

Take a step further by ensuring that you have a fire alarm system installed. A reliable fire alarm can alert people immediately in case of fire. Residential or commercial fire alarm systems and installation costs depend on several factors but range from £50 for a simple one battery alarm to over £5,000 for a fully advanced integrated system.

What factors affect the cost of fire alarm installation?

Fire alarm installation costs depend on the type of fire alarm system you need, the size of your premises, if you want your fire alarm system monitored or unmonitored, and the number of sensors or detection elements within the system. 

Type of fire alarm system

There are inexpensive battery-powered alarms that you can buy for £10 to £15. These types of alarms are easy to install. If you hire a service provider for installation, expect to pay around £40 to £75. Mains powered alarms, which cost about £65 to £250, should be safely installed by an electrician. The cost to install this type of system is £75 to £125 per alarm.

There are also smart-enabled fire alarms available in the market. You have two options: For a battery-powered alarm, the cost ranges between £80 to £100 with installation. For a mains powered smart alarm, the cost will range between £105 to £250. The biggest difference between the two stems from the way they are powered.

Size of your premises

The size of your premises will determine the number of fire alarms you need. Take note that the more alarms you need, the higher the fitting cost by an electrician.

Ease of access

The electrician may need to access your consumer box, and if it’s difficult to do so, running the wires may add to the overall cost. If wires cannot be run above the ceiling, you will need to pay extra for them to be boxed or tacked into position.

Monitoring

The difference between a smoke detector and a fire alarm is whether it’s monitored or not. Similar to installing a burglar alarm, a fire alarm system is watched 24 hours a day, seven days a week by a monitoring service provider. If an emergency arises, day or night, the team immediately calls the nearest fire department to minimise any damage. Monthly charges for the monitoring system fall anywhere between £15 to £45.

Installation costs

Manual or automatic fire alarm system prices depend on the manufacturer. Some system providers require the fire alarm system to be installed by their own installers to ensure that the job is done according to their guidelines. Other alarm providers exclude the installation from their packages and leave it to the homeowner or a third party. 

To get a fire alarm installed by an installation service provider, expect to pay around £100. This also varies depending on your location or choosing a tradesperson, which will cost you about £30 to £50.

What’s involved in installing a fire alarm system?

For battery-powered alarm installation, it’s a simpler process: 

  • Decide where to install it.

  • Keep it away from light fittings and bathroom doors.

  • Remove the cover and screw the base to the ceiling.

  • Pop in the batteries and replace the cover.

For a mains-powered alarm, you may need to hire an electrician to save yourself the hassle and make sure it’s safely done:

  • The electrician checks if there is a dedicated slot on your consumer unit to run your fire alarms off. This is usually a 6 amp circuit breaker. 

  • Power off. Then the wires are first run to the consumer unit.

  • Depending on the location of the alarms and its proximity to the consumer unit, the smoke alarm may be run above the ceiling or it has to be boxed in.

  • Consumer unit wire is connected to the smoke alarm. If the alarm system is linked, then a second wire is connected at the same time, which will link another alarm in the chain.

  • The smoke alarm is screwed and attached to the ceiling.

  • The electrician checks the connections, then the cover is put back on.

What are the additional factors that affect the cost of fire alarm installation? 

Now that you have an idea about fire alarm siren prices, you must plan ahead. Don’t forget to check on these considerations before you hire a professional installer.

Getting an electrical safety certificate

If you are planning to rent your property or have issues with the wiring, opt to get an electrical safety certificate. Combine this with fire alarm installation since most electricians are experienced to do both. The average cost of getting an electrical safety certificate is £120.

Rewiring your home

If your home is older and has not undergone renovations in recent years, then it’s a wise choice to have your electrician check if it has wiring issues. If it needs rewiring, it can be an issue with your insurance coverage. If left unresolved, it can get costly in the future, getting as high as £4,000.

Fitting a security system

While you are at it, you may want to check your security system as well if it needs an upgrade, or you may need to install one if you haven’t. Expect to pay around £500, depending on the size of your home or building.

Prepare ahead and make sure that your fire alarm system - which can help save lives in case the need arises - is installed properly. To get an accurate quote for fire alarm installation, put up a task on Airtasker and connect with nearby professionals in minutes!

FAQs

How much does fire alarm system maintenance cost?

There is a legal obligation that the fire detection system is in good working condition and strictly adheres to regulatory standards. Your fire alarm system is recommended to be checked at least bi-annually by fire alarm engineers certified by the required British Standards to carry out relevant identification and paperwork. Fire alarm installations are governed by British Standard BS 5839-6:2019, which is a protocol of practice for fire discovery and fire alarm systems for properties.

Can I install a fire alarm myself?

It depends. For grade A fire alarm systems, the cost of installation may be higher due to the job’s complexity. However, it’s best to leave it to a professional. They can hold a thorough risk assessment and ensure the system is wired correctly.
