For commercial & multi-residential property teams

External / cavity fire barriers

Bring documented external and cavity barrier requirements into a clear project brief.

When this work is needed

An investigation or project design has identified external or cavity barrier requirements. The scope may involve concealed construction, access constraints and interfaces with facade or roofing systems.

Typical projects

Work arising from documented cavity investigations
Barrier requirements within an approved refurbishment scope
Further investigation needed to establish a remedial package

What needs to be established

Share the investigation findings and available construction details. The specialist must establish the system, substrate, cavity and interface requirements with the relevant design team. Existing reports and photographs do not replace project-specific assessment.

A useful starting brief

Survey findings, facade or cavity drawings, available product records and access constraints.

Add the town, UK nation, building use, procurement stage and intended timescale. Unknown quantities and budgets can be clarified later.

Who this service is for

Managing agents, housing providers, facilities teams, commercial owners and organisations managing buildings or portfolios across the UK. Contractor availability is reviewed for each enquiry.

A managed introduction

Send your report or describe the work. We help structure the requirement, clarify missing information and review eligible contractors against the location, scale and relevant evidence. Contractor interest is recorded before an approved introduction is made against your project reference.

Practical questions

Before you get started

Can you assess the safety of an external wall?

PFL does not carry out external-wall risk assessment or statutory compliance sign-off. We help structure documented requirements and consider suitable specialist introductions.

What if the barrier locations are uncertain?

Identify what is known and the areas requiring investigation. Intrusive access and a defined survey scope may be needed before a firm remedial quotation.

Requirements vary by building, project and UK nation. Technical advice and decisions about relevant fire-safety and building requirements remain with the appropriate professionals.
