Protecting lives and homes with over 20 years of experience

At BCK Fire Sprinklers Ltd, we design, install, and maintain fully compliant fire sprinkler systems in line with BS 9251:2021 – the British Standard for domestic and residential properties. This standard ensures that every sprinkler system offers reliable, life-saving protection where people live, from individual homes to large apartment blocks and care facilities.

​

What BS 9251:2021 Covers

BS 9251:2021 sets the benchmark for:

​

• System design – ensuring effective coverage and water flow to control or extinguish a fire quickly.

• Water supplies – from direct mains connections to storage tanks and booster pumps.

• Installation and components – selecting the right pipework, fittings, and sprinkler heads.

• Testing and maintenance – routine checks to keep systems in peak condition.

​

It applies to a wide range of residential buildings, including:

​

• Houses, flats, and maisonettes

• HMOs and student accommodation

• Sheltered housing and care homes

• Residential blocks and mixed-use developments

​

The 2021 Update

The latest version of the standard introduced several key improvements:

​

• A new Category 4 for taller or higher-risk residential buildings.

• Updated guidance on which rooms and areas require sprinkler coverage.

• Revised rules for sprinkler head spacing and water supply design.

• Greater emphasis on system reliability, maintenance, and long-term safety.

​

These updates help ensure sprinkler systems meet modern building safety expectations and offer consistent, dependable protection.
