Identify hidden breaches. Restore compartment integrity. Meet your legal obligations under the Fire Safety Act 2021 and Building Safety Act 2022.
Fire stopping is the passive fire protection used to seal openings and gaps around services — pipes, cables, ducts — where they penetrate walls, floors, and ceilings that form part of a fire compartment.
Without properly installed fire stopping, fire and smoke can spread rapidly between compartments, bypassing fire doors and other safety measures entirely. Even a small unsealed gap around a cable tray can allow hot gases to pass through in minutes.
Fire stopping products include:
Fire compartmentation is the division of a building into separate fire-resisting sections (compartments) to contain the spread of fire and smoke. Compartment walls, floors, and ceilings are designed to resist fire for a rated period — typically 30, 60, or 120 minutes.
Each compartment is only as strong as its weakest point. A single unsealed penetration — a cable hole, a pipe run, an unsealed duct — can compromise an entire floor or building. This is why compartmentation surveys are essential: they systematically check every compartment line for breaches.
Compartmentation breaches are common, often hidden, and frequently caused by routine works.
Important: In our experience, most buildings contain hidden compartmentation breaches — many created during otherwise routine maintenance and refurbishment works.
A single breach allows fire and smoke to pass between compartments, accelerating spread and putting lives at risk.
The Fire Safety Order 2005, Fire Safety Act 2021, and Building Safety Act 2022 place legal duties on responsible persons to maintain compartmentation.
Insurers increasingly require documented evidence of compartmentation compliance. A survey provides that evidence.
A clear, end-to-end process from identifying breaches to certified remediation.
Full visual inspection of all accessible compartment lines, penetrations, voids, and cavity barriers. Systematic, floor-by-floor assessment.
Photographic evidence of every breach. Full defect schedule with location, severity rating, and recommended remedial action.
Installation of fire stopping products to manufacturer’s specification. Intumescent collars, sealants, fire batts, cavity barriers — the right product for every penetration.
Completion record with product data sheets, photographic sign-off of every remediated penetration, and full audit trail.
A compartmentation survey is a systematic inspection of a building’s passive fire protection. We check all penetrations, seals, cavity barriers, and construction elements to identify any breach that could allow fire or smoke to spread between compartments.
We produce a full defect schedule with photographs, exact locations, severity ratings, and recommended remedial products. The report is suitable for responsible persons, housing associations, NHS trusts, schools, commercial landlords, and FM companies requiring evidence of compliance.
Suitable for: Housing associations, NHS trusts, care homes, schools, commercial landlords, FM companies, and any building where compartmentation integrity is a legal or contractual requirement.
A systematic inspection of a building’s passive fire protection to identify breaches in compartment lines. We check all penetrations, fire stopping, cavity barriers, and construction elements, producing a full defect schedule with photographs and remedial recommendations.
If your building is subject to the Fire Safety Act 2021 or Building Safety Act 2022, you should be able to demonstrate your compartmentation is intact. Many buildings have never been surveyed and contain hidden breaches — often created during routine maintenance works.
It depends on building size, number of floors, and accessibility. A typical residential block might take 1–3 days. We’ll give you a clear time estimate after discussing your building.
