Water Mist

Watermist NozzleWater Mist Systems to BS 8458: 2015. 
Our company is dedicated to designing and installing domestic and residential water mist systems to not only meet but exceed BS8458:2015 throughout England and Wales.

Residential and Domestic Water Mist Systems.

Water Mist in domestic properties have grown in demand over the last 10 years due more stringent Fire & Building Regulations. Building Regulations Approved document B can allow water mist systems to be used instead of other passive fire protection. For example: the removal of walls to allow open plan living, removal of secondary means of escape if the building is over 7.5m high, allows open stairways and more. To allow for these relaxations all domestic and residential sprinkler systems must comply with BS8458:2015.

As of 2016, Wales was the first country in the world to introduce legislation making it compulsory for all newly built houses and flats to be installed with fire sprinklers to BS8458:2015.

Water Mist Systems can also allow for some buildings to be constructed that would otherwise not get planning consent. For Example: Buildings with limited access for fire brigade.

With the rapid advancement of technology water mist have become barely noticable and aesthetically pleasing, only part visible is an small nozzele that`s housed in a GU10 Spotlight fitting that comes in any colour of your choice


Most of our water mist systems are installed with high pressure hydraulic hoses these are alot smaller than CPVC pipe work used on fire sprinkler systems, they are also flexible making water mist systems an advantage for retro fitting

Water Supplies

There is no need for a dedicated supply for water mist systems so that is another advantage over fire sprinkler systems

Generally your water mains in your property are more than adequate to run a water mist system so no need for additional water mains saving you money.

Water Mist Installation Process

Design – Drawings are produced with mist nozzle locations and pipework indicated. Hydraulic calculations carried out to determine system requirements.

1st fix – Our first fix stage involves the running of cables and hoses/pipe work. This is generally carried out at electrical first fix stage when access to walls and ceilings are open. During the first fix we will run high pressure hosing from our agreed pump position to each nozzle, we will also install a fire retardant cable from our pump to the position of the incoming water supply.

2nd fix and commission – The Second fix stage of the installation is when everything comes together.

The nozzles will be installed and pressure tested for a final time, the pump will be installed in accordance with the water and electrical supplies. We will then undertake a commissioning of the system which is a test run of the pump and nozzles, this ensures us that the system will operate as designed and allows us to provide a certificate of conformity at the end of the project. The certificate can then be forwarded to building control for project completion and full building control sign off.


Once the system has been installed, certified and signed off by building control, all of the works are complete.

The system requires an annual maintenance by a Suppression Solutions approved installer
