Fire Compartmentation Services
Our services identify weaknesses in fire compartmentation within buildings: protecting lives, ensuring compliance, and enabling swift remediation. Designed for residential, commercial, and mixed-use properties.
Watch this short video for a bit more detail on the compartmentation services we offer and when they’re needed…
We provide a range of services that help to locate breaches and vulnerabilities in your building’s compartmentation, ensuring compliance with the Regulatory Reform (Fire Safety) Order 2005 and the Building Safety Act.
Type 2 Fire Risk Assessments, Type 4 Fire Risk Assessments, and Fire-Stopping Surveys all help duty holders understand where fire and smoke could potentially spread.
Our reports are site-specific, prioritised by risk, and accompanied by clear photographic evidence. They are all available digitally through our interactive portal for ease of review and instruction.

The Technical Bit
Type 2 and 4 Fire Risk Assessments assess whether a building’s internal structures — such as walls, floors, ceilings, risers, and service penetrations — effectively prevent the spread of fire and smoke.
Fire Stopping Surveys identify visible breaches in compartmentation, assessing for open holes, unsealed gaps around service penetrations, and that fire-stopping measures are appropriate and quality.
These services support compliance with the Regulatory Reform (Fire Safety) Order 2005, which places duties on the Responsible Person to maintain fire-resisting construction in order to protect residents, staff, and visitors.
Our compartmentation and fire stopping services identify breaches in compartmentation and provide 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-Stopping 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 with Fire-Stopping Surveys, 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 an action plan with recommended remedial actions.
Type 2 Fire Risk Assessments only assess communal areas; Type 4 Fire Risk Assessments will need access to residences.
Reports rely on the level of access granted and may highlight limitations where full visibility couldn’t be obtained, these should not be ignored.
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-Stopping Survey is carried out across all communal and service areas of residential buildings, and reviewed regularly, especially after refurbishment or contractor activity.
Ensure any surveys or assessments are conducted by competent professionals with knowledge of fire safety construction and relevant guidance (e.g., BS 9792, 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-Stopping surveys with your wider fire strategy or Fire Risk Assessment process to improve visibility, reduce duplication, and support Golden Thread compliance.
