Fire risk assessments

On the evening of Thursday 25 June 2026, a major fire broke out at a commercial property on Rye Lane in Peckham, south London, close to Copeland Park. London Fire Brigade control officers took the first of more than 40 emergency calls at 20:54, and the Brigade mobilised crews from Peckham, Old Kent Road, Brixton and surrounding stations. At the height of the incident, fifteen fire engines and around 100 firefighters were in attendance, with two of the Brigade's 32-metre turntable ladders deployed as water towers to fight the fire from above.

Station Commander Craig Abbott, who attended the scene, confirmed that a department store was alight at the height of the fire, alongside an adjoining shop and storage unit. A significant volume of smoke was produced, prompting advice for local residents to keep windows and doors closed, and for the public to avoid the area while roads were cordoned off and bus routes diverted. The fire was brought under control by 23:50, although crews remained on scene overnight to fully extinguish it and dampen down hotspots. At the time of writing there are no confirmed reports of injuries.

It's a striking reminder of how quickly a fire in a busy retail environment can escalate, and how much resource is needed to bring it under control once it takes hold. A response of fifteen pumps and around 100 firefighters is a significant commitment, and it underlines a point we make constantly to commercial clients: by the time a fire is visible from the street, the building has already lost the battle to contain it internally. The real fight against fire loss happens long before the Brigade arrives, in the design, maintenance and management of the building itself.

Why Compartmentation Matters

Compartmentation is one of the most important, and most frequently overlooked, elements of passive fire protection in any commercial building. The principle is simple: a building is divided into fire-resisting compartments, using fire-rated walls, floors, doors and sealed service penetrations, so that if a fire starts in one area it is held there for a defined period rather than spreading freely through the structure.

In a large retail premises such as a department store, effective compartmentation does several critical jobs at once. It protects escape routes long enough for staff and customers to get out safely. It limits fire spread between sales floors, storage areas and back-of-house spaces, which is particularly important where stockrooms hold significant fuel loads of packaging, textiles and combustible stock. And it buys firefighters time to mount an effective attack on the fire before it takes hold of the whole structure, which is exactly the kind of advantage that can be the difference between a contained incident and the scale of response we saw in Peckham.

Compartmentation fails in fairly predictable ways: fire doors wedged open or fitted with the wrong rating, gaps around pipework and cabling left unsealed after maintenance work, suspended ceilings and voids that allow fire to travel above compartment walls, and storage stacked against or blocking fire-resisting partitions. None of these are dramatic failures on their own, but together they can turn a contained shop fire into a building-wide incident.

The Importance of a Suitable and Sufficient Fire Risk Assessment

This is precisely why the Regulatory Reform (Fire Safety) Order 2005 places a legal duty on the Responsible Person in any commercial premises to ensure a suitable and sufficient fire risk assessment is carried out, kept up to date, and acted upon. For a retail unit, and particularly a large multi-floor store with mixed sales and storage areas, that assessment needs to look specifically at compartmentation: are fire doors fitted, rated correctly and self-closing where required, are walls and floors that should be fire-resisting actually intact, and have any alterations or fit-out works compromised the structure's fire strategy since it was last assessed.

A fire risk assessment isn't a paperwork exercise to be filed and forgotten. It should identify the specific weaknesses that allow a fire to spread beyond its point of origin, and it should be reviewed whenever the building, its use, or its occupancy changes, not just on a fixed annual cycle. Storage layouts change, units get subdivided, tenants come and go, and each of those changes can quietly undermine compartmentation that was sound when the building was last surveyed.

Incidents like the Peckham fire don't yet tell us what role, if any, compartmentation played, and the cause has not been confirmed. But they're a useful prompt for any business operating from a commercial premises to ask a straightforward question: if a fire started in our building tonight, would it stay contained, and is our fire risk assessment recent enough, and detailed enough, to know the answer?

If you manage a commercial property and aren't confident your fire risk assessment reflects the building as it actually is today, that's exactly the gap we help close. Get in touch with Whale Fire to arrange a fire risk assessment.
