What is passive fire protection?

Passive fire protection is the built‑in fabric of a building that slows the spread of fire and smoke. It includes fire resisting walls and floors, fire stopping around service penetrations, cavity barriers, dampers, protective coatings, and certified fire doors. Together these measures maintain compartmentation so people have time to escape and the fire service can intervene. Good passive protection supports your duties under the Regulatory Reform (Fire Safety) Order 2005 and relevant building regulations, and it underpins business continuity.

Why choose Complii?

How we can help.

Protect your people, property, and business. Here’s why we’re the right choice for passive fire protection.

Life safety and safer evacuation

Well designed and correctly installed passive measures hold back fire and smoke, protect escape routes, and keep refuge areas and stair cores usable for longer. This buys precious time for occupants and responders.

Legal assurance and best practice

Work is specified and delivered in line with manufacturers’ test evidence and relevant British Standards, with third‑party certification where required. This gives Responsible Persons documented proof that precautions are suitable and sufficient.

Reduced damage and downtime

By containing a fire within its compartment of origin, passive measures limit structural damage and water ingress, helping you get back to normal operations sooner.

Clear documentation and traceability

You receive a digital record of locations, products, installation methods, and photographs. Labels and asset tags support the golden thread of information, making future inspections and remedials straightforward.

Proportionate, practical remediation

Targeted surveys focus on the real risks. Remedial work addresses penetrations, voids, and door performance issues without unnecessary disruption, keeping costs proportionate to the risk.

Sector expertise

From healthcare and care homes to education, hospitality, and multi‑residential buildings, experienced teams understand sector specific challenges and coordinate works safely in live environments.

Your questions answered.

  • The law requires you to provide and maintain suitable fire precautions. Passive fire protection is a primary means of achieving this, and your fire risk assessment or fire strategy will set the level of provision your premises need.

  • Typical scope includes fire stopping to walls and floors where services pass through, installation of cavity barriers and fire curtains where specified, inspection and remediation of fire doors, protection of structural steel where required, and checks of dampers and ductwork in fire resisting construction.

  • Independent third‑party certification provides assurance that products and installers are competent and that work follows the tested detail. Many clients and insurers require it, and it helps work stand up to external audit.

  • Include passive protection within your planned maintenance. Fire doors need regular checks for gaps, seals, closers, glazing, and hardware. Following refurbishment or service changes, re‑inspect penetrations and compartments to confirm they remain intact.

  • Passive protection is built into the structure and works without activation. Active protection detects or suppresses fire using systems such as alarms and sprinklers. Buildings usually need both for a complete strategy.

  • Surveys and remedials can be planned in phases, out of hours, or during quiet periods. Intrusive access may be required above ceilings or within risers, but we agree method statements and isolate areas to keep people safe and disruption low.
