Meeting fire compartmentation compliance in the UK is governed by a combination of key legislation that places a clear duty on building owners, managers, and other duty holders.
Regulatory Reform (Fire Safety) Order 2005 (FSO)
The FSO is the primary piece of fire safety legislation in England and Wales. It requires the “Responsible Person” to carry out a fire risk assessment and implement necessary fire safety measures. The assessment must consider the building’s fire compartmentation and ensure it is maintained and effective. Breaches in compartmentation are a significant fire risk and must be addressed.
Fire Safety Act 2021
The Fire Safety Act 2021 clarifies that the FSO applies to the structure, external walls (including cladding, balconies, and insulation), and individual flat entrance doors in multi-occupied residential buildings. This means your legal duty now explicitly includes the compartmentation of a building’s external walls and doors, which were previously a grey area.
Fire Safety (England) Regulations 2022
These regulations, which came into force in January 2023, place specific new duties on the Responsible Person for high-rise residential buildings. This includes providing residents with information on fire safety and undertaking checks of fire doors and other vital fire safety features.
Building Regulations (Approved Document B)
While the FSO covers ongoing fire safety, Approved Document B of the Building Regulations sets out the standards for new buildings and major refurbishments. It dictates the requirements for fire compartmentation and the fire resistance of materials used. Any modifications to a building must comply with these standards to ensure the integrity of existing compartmentation is not compromised.
