With our highly experienced team, we specialise in residential and domestic fire sprinkler systems design to BS 9251 and have completed numerous projects from a small domestic residence to high-rise apartment blocks.

We can design a fire sprinkler system for you, however large or small the project, and provide guidance on types of sprinklers and water supplies that would be most suitable.

Calculations

We use the industry-leading hydraulic calculation software FHC by Canute LLP for all of our projects. We strongly believe that residential sprinklers will help save lives, property, and the environment. With our expert knowledge of this technology, it’s not surprising that ADCB can undertake the required hydraulic calculation, and you can also have our expertise to help you through.

BS 9251:2021 THE BRITISH STANDARD FOR FIRE SPRINKLERS

BS 9251 is the British Standard for Fire Sprinkler Systems in the UK. This is the 3rd version of this standard, originally published in 2005, then reviewed and amended in 2014 and 2021 with help from members of the fire service and key players in the industry.

BS 9251 covers:

• Individual dwellings (houses, flats, and maisonettes)
• Houses of multiple occupancy (HMOs)
• Bed and breakfast accommodation
• Boarding houses
• Blocks of flats
• Residential care premises
• Dormitories
• Hostels

The standard does not cover schools, hospitals, hotels, or commercial buildings. Any sprinkler systems for commercial properties are covered by BS 12845:2021 The British Standard.

The types of property covered by BS 9251 vary in size and type of resident and therefore are split into risk categories. These categories range from 1-4:

• Category 1: covers individual dwellings (houses), HMOs, B&Bs, Boarding Houses (Typically a domestic dwelling (house) for a single family).
• Category 2: covers blocks of flats below 18m (typically less than 6 floors), small residential care homes, sheltered and extra care housing.
• Category 3: covers large residential care homes, student accommodation, dormitories, hostels.
• Category 4: covers blocks of flats 18m and above. (Typically about 6 floors or more)

Each category has minimum design parameters which determine the number of heads that should be used to calculate the amount of water and pressure required to run the system:

• Category 1: sprinkler systems will require a minimum run time of 10 minutes and the calculation should include 1 or 2 heads in the calculation. Average 84-100 litres/minute. Tank size 1m³ to 1.5m³.
• Category 2: sprinkler systems require a minimum run time of 30 minutes and the calculation should include 1 or 2 heads in the calculation. Average 84-100 litres/minute. Tank size 3m³ to 4.5m³.
• Category 3: sprinkler systems must have a minimum run time of 30 minutes and the calculation should include 2 or 4 heads in the calculation. Average 168-200 litres/minute. Tank size 6m³ to 9m³.
• Category 4: sprinkler systems as per Category 3 but must have a minimum run time of 60 minutes. Two or more tanks, each capable of providing 50% or more of the required water supply to the system. Backup power supply.

Certain non-residential accommodation falls within the scope of the new BS 9251:2021 including:

• Car parking within/beneath flats/domestic garage
• Bin Store, residents’ storage sheds
• Plant rooms (PTSN/CCTV/Electrical rooms)
• Laundry/utility room: domestic or institutional (e.g. care home)
• Kitchens: domestic, self-catering (e.g. student accommodation, residential care)
• Foyer/reception/limited office areas (e.g. concierge or site management)

ADCB LTD will design and hydraulically calculate the system to find the required system demand and delivery method.
