IIf you’re a property manager, contractor, or building owner in London, chances are you’ve asked: “How much does a fire stopping survey or installation cost?” With increasing pressure on fire safety compliance, especially since updates to the Building Safety Act, this is a vital question—and one that doesn't always have a simple answer.

In this article, we’ll explain what affects the cost of fire stopping work in London, what’s involved in a fire stopping survey, and how to budget realistically for compliance.

What Is a Fire Stopping Survey?

A fire stopping survey is a detailed inspection of a building’s fire compartmentation. Its purpose is to identify:

Breaches in fire walls or floors (from cables, pipes, ducts, etc.)
Missing or non-compliant fire-stopping materials
Inadequate cavity barriers or linear joint seals
Non-compliant penetrations in service risers and voids

These surveys are typically carried out in line with Regulatory Reform (Fire Safety) Order 2005 and PAS 9980 guidance, and are essential for buildings of multiple occupancy or complex design.

What Factors Influence the Cost?

When quoting for fire stopping surveys or installations in London, several factors come into play:

1. Size and Complexity of the Building

A 1-bed flat in a converted house will cost significantly less than a 10-storey block of flats or a commercial office.
Buildings with extensive M&E services or historic fabric require more intrusive investigation.

2. Access Requirements

Survey costs rise if access equipment is needed (e.g. towers, MEWPs).
Live buildings (e.g. schools, hospitals) may require phased or out-of-hours work.

3. Type of Installation Work Required

Sealing a single pipe with intumescent mastic may cost £30–£50.
Rebuilding a compartment wall or installing cavity barriers could cost hundreds to thousands.

4. Documentation and Certification

Clients requiring digital reports, photographic evidence, and third-party certification (e.g., IFC, LPCB) should expect to pay more for this added assurance.

Typical Price Ranges in London (2025)

Service	Typical Cost (London)
Fire Stopping Survey (small site)	£350–£750
Fire Stopping Survey (multi-floor)	£900–£3,000+
Fire Stopping Installation (per item)	£30–£300 per penetration
Large Remedial Works	£5,000–£25,000+ project-based

These are indicative only. Each building requires a bespoke assessment.
