Westminster contains some of London's most significant residential and commercial building stock, from Edwardian mansion blocks in Maida Vale and Marylebone to large commercial office buildings across Victoria, the West End and Whitehall. Fire compartmentation in these buildings is essential to protecting occupants and ensuring compliance with the Building Safety Act.
Our fire compartmentation surveys in Westminster assess passive fire protection across all building types. We identify breaches in compartment walls and floors, test fire stopping at service penetrations, and evaluate cavity barrier provision. We work with Crown Estate managing agents, Westminster City Council, private freeholders and commercial landlords throughout the borough.
Whether you are responsible for a mansion block in St John's Wood, a listed commercial building in Mayfair, or a high-rise residential tower in Pimlico, our surveys provide the evidence base for remediation planning and regulatory compliance.
Assessment of fire stopping in Westminster mansion blocks and commercial premises, where decades of service installations and tenant alterations have frequently compromised fire-separating elements at penetration points.
Inspection of compartment wall and floor construction in period mansion blocks, purpose-built residential buildings and multi-storey commercial premises, checking for correct fire resistance and integrity.
Detailed survey of pipe, cable and duct penetrations through compartment lines in Westminster's complex commercial and residential buildings, including historic riser shafts in mansion blocks.
Review of cavity barrier provision in external wall systems, roof voids and concealed spaces, particularly in Westminster buildings that have undergone cladding over-cladding or roof-level extensions.

View ServiceMansion blocks in Maida Vale and Marylebone, purpose-built residential towers in Pimlico and Victoria, commercial office buildings across the West End, and mixed-use properties along Edgware Road all benefit from compartmentation surveys. Any building where fire needs to be contained within defined compartments to protect means of escape should be assessed.
Many Westminster mansion blocks were built before modern fire safety standards and have undergone decades of alteration. Original fire-separating construction may have been compromised by new service routes, removed walls, and upgraded kitchens and bathrooms. These buildings often have continuous roof voids and unprotected service risers that allow fire and smoke to spread between dwellings.
The Building Safety Act 2022 places new duties on principal accountable persons for higher-risk buildings over 18 metres. In Westminster, this affects numerous residential towers and large mansion blocks. A fire compartmentation survey provides essential evidence for the building safety case and ongoing compliance with the new regulatory framework.
Yes. We have experience surveying listed buildings across Westminster, including Grade I and Grade II listed mansion blocks and commercial premises. Our surveyors understand the constraints of listed building consent and can recommend fire compartmentation improvements that respect the building's heritage significance while meeting modern safety requirements.
