What is it?
Fire stopping fills gaps where pipes, cables and ducts pass through fire-rated walls and floors, maintaining the wall or floor's fire resistance. Work should be carried out by trained installers using tested systems (e.g. EI 60 or EI 120) and recorded with photographic evidence and product certification.
Who typically needs this service?
- Higher-risk residential buildings undergoing remediation
- Refurbishment and fit-out projects
- Landlords post-FRA to close out remedial actions
- Construction contractors completing handover packs
What good looks like
- Third-party accredited installers (e.g. FIRAS, IFC, LPS 1132)
- Approved systems matched to substrate and service penetration
- Photographic record per penetration with product references
- Survey and remediation tracked against the building's compartmentation drawings
Practical considerations
Compartmentation surveys identify breaches in fire-rated walls and floors — from missed riser cupboards to abandoned cable routes — and produce a prioritised schedule of remediation. Third-party accredited installers should match each system to the substrate and the service passing through it: a single product cannot solve every penetration. Records should be auditable per location, ideally tagged to a compartmentation drawing, so future works can be carried out without re-surveying the whole building.

Frequently asked questions
What does fire stopping actually involve?
Sealing gaps where pipes, cables, ducts and other services pass through fire-rated walls and floors, using tested systems that match the substrate and the service. Each penetration is recorded with photographs and product references for the building's compliance pack.
Do I need third-party accredited fire stopping installers?
It is strongly recommended. Schemes such as FIRAS, IFC Certification and LPS 1132 confirm installer competence and require tested systems to be used correctly. Many insurers and principal contractors now insist on third-party accreditation.
What is a compartmentation survey?
A structured inspection of fire-rated walls and floors to identify breaches, missing fire stopping and abandoned penetrations. The survey produces a prioritised schedule of remediation, often tied to the building's compartmentation drawings.
