Fire Compartmentation Surveys
Our surveys identify weaknesses in fire compartmentation within buildings—protecting lives, ensuring compliance, and enabling swift remediation. Designed for residential, commercial, and mixed-use properties.
We provide detailed Fire Compartmentation Surveys that locate breaches and vulnerabilities in your building’s passive fire protection systems—ensuring compliance with the Fire Safety (England) Regulations 2022 and the Building Safety Act.
Our compartmentation reports are site-specific, prioritised by risk, and accompanied by clear photographic evidence and floorplans. We inspect walls, floors, risers, service penetrations, voids, and fire-stopping materials, helping duty holders understand where fire and smoke could potentially spread.
All surveys are available digitally through our interactive portal for ease of review and instruction.
Whether you’re managing a single high-rise or an extensive portfolio, our team helps you take decisive action to restore and maintain compliance.

Why Do I Need a Fire Compartmentation Survey?
The Technical Bit
Fire compartmentation surveys assess whether a building’s internal structures—such as walls, floors, ceilings, risers, and service penetrations—effectively prevent the spread of fire and smoke. These surveys support compliance with the Regulatory Reform (Fire Safety) Order 2005 and the Fire Safety (England) Regulations 2022, which place duties on the Responsible Person to maintain fire-resisting construction. In multi-occupied residential buildings, communal areas are considered part of the workplace under these regulations, meaning adequate compartmentation is essential to protect residents, staff, and visitors.
The survey identifies breaches in compartmentation and provides recommendations to restore fire resistance, in line with the building’s original design intent and relevant standards such as BS 9999 and PAS 9980.
Fire compartmentation surveys reflect the condition of the building at the time of inspection; breaches may not be visible without access to voids or concealed areas.
Compartmentation should be checked regularly, especially after works by contractors (e.g., cabling, plumbing, or maintenance) which may compromise fire-resisting barriers.
The survey should include clear photographic evidence, risk prioritisation, and a schedule of breaches with recommended remedial actions.
Reports rely on the level of access granted and may highlight limitations where full visibility couldn’t be obtained, these should not be ignored.
All advice and recommendations must be based on observed breaches and best practice guidance; assumptions are not sufficient for life safety.
Fire compartmentation requirements are rooted in legal duties under the Regulatory Reform (Fire Safety) Order and associated guidance, only the Courts can definitively interpret these duties, but surveys help demonstrate proactive compliance.
Worth Knowing:
What To Do…
Ensure that a fire compartmentation survey is carried out across all communal and service areas of residential buildings, and reviewed regularly, especially after refurbishment or contractor activity.
Ensure the survey is conducted by competent professionals with knowledge of fire safety construction and relevant guidance (e.g., PAS 9980, BS 9999).
Ensure that breaches are acted upon in accordance with their priority level, and that works are tracked through to completion and re-inspection if required.
Where possible, integrate fire compartmentation surveys with your wider fire strategy or Fire Risk Assessment process to improve visibility, reduce duplication, and support Golden Thread compliance.
