The Royal Borough of Kensington and Chelsea has an exceptionally high concentration of mansion blocks, period conversions and prestigious residential buildings where fire compartmentation is a critical life safety consideration. From the red-brick mansion blocks of Earl's Court and South Kensington to the stucco terraces of Notting Hill, many of these buildings pre-date modern fire safety standards.
Our fire compartmentation surveys across Kensington and Chelsea identify deficiencies in fire-separating construction, assess fire stopping at service penetrations, and evaluate cavity barrier provision. We work with managing agents, freeholders, residents' associations and the council to address passive fire protection in buildings of all ages and types.
Whether you manage a large mansion block in Holland Park, a converted terrace in Chelsea, or a purpose-built residential tower in North Kensington, our RICS regulated surveys provide a thorough assessment of compartmentation adequacy and prioritised remediation recommendations.
Assessment of fire stopping integrity in Kensington mansion blocks and converted period properties, where historic and modern service installations have commonly created unsealed penetrations through compartment lines.
Inspection of fire-separating walls and floors between dwellings in mansion blocks, between commercial and residential uses in mixed-use buildings, and in purpose-built residential blocks across the borough.
Survey of mechanical, electrical and plumbing penetrations through fire compartment boundaries, including historic cast-iron risers and modern plastic pipework in Kensington and Chelsea mansion blocks.
Review of cavity barrier provision in roof voids, floor constructions and external wall systems, with particular attention to Kensington mansion blocks with continuous loft spaces and concealed voids.

View ServiceMany mansion blocks in Kensington and Chelsea were constructed in the late Victorian and Edwardian periods with timber floors, lath-and-plaster partitions and continuous roof voids that provide limited fire resistance by modern standards. Subsequent alterations, including new bathrooms, kitchens and service upgrades, have often further compromised compartmentation. A survey identifies these deficiencies and prioritises remediation.
Compartment walls between dwellings should typically achieve 60 minutes of fire resistance, though the required standard depends on building height, age and use. In many Kensington mansion blocks, the original construction may only achieve 30 minutes or less, and breaches from service penetrations can reduce this further. Our survey assesses actual performance against the required standard.
In many cases, yes. Fire stopping at service penetrations can often be installed without significant disruption to residents. Cavity barriers in roof voids and upgraded fire doors can also be retrofitted relatively efficiently. For more extensive deficiencies, such as compartment walls requiring upgrading, we can advise on phased remediation programmes that minimise disruption in occupied buildings.
We survey buildings across North Kensington and the wider borough, including those directly and indirectly affected by the Grenfell Tower fire and its ongoing public inquiry. Our compartmentation surveys address the passive fire protection concerns raised by the inquiry and help building owners demonstrate that internal fire-separating elements are adequate.
