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 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 proactive 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 reliable, safe and cost-effective. They require less maintenance than fire alarms and 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

Properties with insufficient water pressure

The costs in the table above apply if the mains water supply to your property is of sufficient pressure. If the mains pressure is insufficient, the sprinkler system will need to be fed from a stored water supply.

If this is the case, a pump and tank will need adding, increasing system costs by £1,500 – £3,000.

A reputable system fire suppression specialist will be able to tell you if your water pressure requires you to install a pump and tank system.

Automatic fire sprinkler system costs
