Fire suppression system cost guide

When it comes to owning a property, one of our main priorities is ensuring it meets all the required health and safety standards. Research into fire suppression system costs is on the rise, which is why we’ve put together this guide to discuss:

  • The benefits of a fire suppression system
  • Commercial fire sprinkler system costs
  • Residential fire sprinkler costs

Although house fires are rare in comparison to other home safety concerns, the UK alone reported 157,156 fire incidents in the year ending December 2019. With tragedies like Grenfell, fire-proofing our commercial or residential properties is something worth investing in.

Average price of a fire suppression system = £1500
Avg domestic sprinkler system cost = £15-25 per m2

What is a fire suppression system?

A fire suppression system is a safety feature that ‘seeks to extinguish fires through the application of a substance.’ They are engineered to detect fires when they start using heat and smoke sensors. Once activated, they deploy a substance such as foam, mist or water to extinguish the flames.

Benefits of a sprinkler system

Active fire protection

Where fire alarms alert you to a hazard, sprinkler systems take an active role in protecting you from said hazard. They offer more active fire protection that doesn’t require manual input.

Prevents fire damage

As the sprinklers are activated as soon as the system detects smoke or fire, damage to your property is kept to a minimum. Evidence shows that properties with fire sprinkler installations reduce damage by up to 90%.

More effective than fire alarms and extinguishers

Fire sprinkler systems are more reliable, safe and cost-effective. They require less maintenance than fire alarms or extinguishers and don’t need to be activated manually to protect your home. They also eradicate the need to call the fire brigade and wait for a fire engine to show up.

Factors affecting the cost of a sprinkler system

The cost of fire sprinkler systems can add up to the same amount it would cost you to have new carpets fitted. However, there are various factors that affect the overall price of installing a sprinkler system. These include:

  • The size and design of a building
  • The number of sprinklers required
  • Any recent refurbishments undertaken
  • Whether the property is a new build or not
  • Where the mains supply is located
  • The property’s location
