Bin Store Fires: The Overlooked Risk in Multi-Occupancy Blocks
Bin store fires rarely make the headlines, yet they are among the most frequent fire incidents attended by UK fire and rescue services. Communal refuse areas sit close to entrances, escape routes and ground-floor flats, they hold a constant supply of fuel, and they are usually the least secure part of the building. For landlords, managing agents and housing associations, that combination makes bin stores one of the biggest unmanaged risks on the estate.
This article explains why bin store fires start, what the law expects responsible persons to do about them, and the practical steps that bring the risk down to an acceptable level.
Why bin store fires are so common
UK fire and rescue services attend around 30,000 refuse-related fires every year. A large share of those are deliberate. Wheelie bins and open skips are an easy target: they are accessible, they contain cardboard and plastic that ignites quickly, and they are often out of sight of residents and cameras.
Arson isn’t the only cause. Discarded smoking materials, hot ashes from barbecues, and increasingly lithium-ion batteries from e-scooters, vapes and power tools thrown into general waste all start fires without anyone intending them to. Once a bin is alight, a fully loaded 1,100-litre container can produce enough heat to crack glazing and ignite cladding, soffits and timber doors within minutes.
The features that turn a bin fire into a building fire
The danger with bin store fires in flats is proximity. Most bin stores were designed decades ago for a fraction of today’s waste volume. Overflow bins end up stored against external walls, under windows, or in the entrance lobby itself. When a fire starts there, it has a direct route into the building.
The other factor is the escape route. A bin store sited beside the main entrance, or inside a ground-floor lobby, can fill the stairwell with smoke before anyone on the upper floors knows there is a problem. In a block with a single staircase, that is a life-safety failure.
What the law says about bin store fires
The Regulatory Reform (Fire Safety) Order 2005 requires the responsible person for any block of flats to carry out and maintain a suitable fire risk assessment covering the common parts. The Fire Safety Act 2021 clarified that this duty extends to the building’s structure, external walls and flat entrance doors so a bin store built into the fabric of the block, or positioned against it, sits squarely within scope.
Government guidance for sleeping accommodation goes further and states that bins should be secured within a compound, away from dwellings, so that they cannot be used to start a fire. Fire risk assessors regularly flag unsecured bins as a significant finding, and enforcement notices citing bin storage are not unusual.
Separation distances
The most widely used rule of thumb is that bin stores should be at least six metres from the building. Where that is not possible, a more accurate method is to take the width of the bins facing the building and add 2.5 metres. That distance is measured from any point where fire could enter doors, windows and vents included. If neither distance can be achieved, the store itself needs non-combustible construction and fire-resisting separation from the block.
Reducing the risk of bin store fires
Preventing bin store fires comes down to three things: controlling access, controlling fuel, and detecting a fire early enough to act.
Control access
Deliberate fires need an opportunity. Lockable, well-lit bin compounds with solid doors remove most of it. Fob or keypad entry for residents and collection crews keeps the store closed the rest of the time. Where anti-social behaviour is an ongoing problem, CCTV covering the compound is both a deterrent and a source of evidence. Our CCTV and access control team fits these systems to communal areas across Lancashire and the North West.
Control fuel
Bulky items mattresses, sofas, pallets should never be left in or beside a bin store. They are the single most common trigger for arson on housing estates. Regular clearance, clear signage about battery disposal, and a collection schedule that matches actual waste volume all reduce the fire load. Rough sleeping or drug use in the store is a warning sign that should be addressed with the local authority, not ignored.
Detect early
Where a bin store is inside the building or attached to it, detection matters. A heat detector linked to the building’s fire alarm gives residents warning before smoke reaches the stairwell. Our fire alarm systems are designed to BS 5839-1:2025, and we can advise on whether your bin store should be brought into the detection zone or treated as a separate compartment.
How a fire risk assessment addresses bin store fires
A competent fire risk assessment will look at the bin store’s location, construction, security and housekeeping, then rate the risk against the guidance above. The output should be a prioritised action plan not a vague recommendation to “review bin storage”.
Typical actions include relocating overflow bins, upgrading a timber store door to a fire-resisting one, adding a lock and lighting, or in the worst cases building a new external compound. Many are low cost. All of them are far cheaper than the alternative.
If you manage a block of flats, an HMO or a mixed-use building and haven’t had bin storage specifically reviewed, our fire risk assessments cover it as standard. The Royal Berkshire Fire and Rescue Service guidance on preventing deliberate fires is a useful starting point for building managers who want to understand the problem before booking an assessment.
Frequently asked questions
Who is responsible for bin store fires in a block of flats? The responsible person under the Fire Safety Order normally the freeholder, managing agent or housing provider must assess and manage the risk. Individual residents are responsible for what they put in the bins, but the store itself is a common part.
Does a bin store need a fire door? If the store is inside the building or shares a wall with it, the door should provide fire resistance appropriate to the compartment. Your fire risk assessment will specify the rating.
Can bins be stored in the lobby temporarily? No. Bins in escape routes are a serious hazard and one of the most common enforcement findings in residential blocks. Even short-term storage should be avoided.
Are lithium batteries really a bin store fire risk? Yes. Batteries crushed in compaction lorries or bins can go into thermal runaway. Signage and a separate battery collection point reduce the chance of one ending up in general waste.
