About Pro-Passive Fire Safety
A family-run business serving southern England. We survey, install and record the work on the parts of a building that contain fire and smoke — fire doors, compartmentation and fire stopping.
Part of Pro Fire Safety GroupWho we are
Passive protection is the part of a building nobody sees until it matters. It deserves a specialist.
Pro-Passive Fire Safety was created to give passive fire protection the specialist attention it deserves. We focus on the building elements that contain fire and smoke: fire doors, compartmentation, fire stopping and remedial works.
We work with building owners, facilities teams, principal contractors, managing agents and other responsible parties to identify defects, understand priorities and put the right remedial measures in place — on live sites, in occupied buildings and around the working day.
Our engineers survey, install and record the work, giving clients a clear evidence trail for building management, insurers and auditors. Nothing leaves site undocumented.
What we do
Every one of them starts with the same question: where does this building rely on being compartmented, and is that still true today?

Sealing penetrations, joints and openings so fire and smoke cannot pass through compartment lines.

Pro-Passive Fire Safety and Pro-Active Fire Safety are the two halves of the Pro Fire Safety Group. Active protection detects a fire and helps people escape it. Passive protection contains it, buying the time that alarms and escape routes depend on. We work from the same office, so nothing falls between them.
Fire alarms, extinguishers, emergency lighting, suppression and training.
