The UK's warehouse and logistics sector faces some of the most demanding fire risks of any commercial environment. Large open spaces filled with combustible goods, high racking that lets fire spread rapidly upwards, complex electrical systems under constant operational stress, and around-the-clock operations that limit maintenance windows all combine to create conditions in which a fire can escalate quickly and cause extensive damage. This guide brings together the latest verified data from the Ministry of Housing, Communities & Local Government (MHCLG), Gov.UK and the Fire Industry Association (FIA) on warehouse and industrial fires — the scale of the problem, the main causes, the cost, the UK sprinkler gap and the legal duties that sit with every warehouse operator.
Key facts and figures
- ~25% of all UK workplace fires in 2024/25 were in industrial premises — the highest proportion of any sector (around 1,656 fires).
- £1 billion in GDP and around 5,000 jobs have been linked to preventable warehouse fires over a five-year period.
- £940 million a year is claimed by UK businesses in fire property insurance, according to FIA figures.
- £657,074 is the estimated average cost of a major fire.
- 18% of all workplace fires are caused by electrical distribution faults — the leading identifiable cause.
- 80% chance of permanent closure for warehouses that fail to recover within one month of a serious fire.
Warehouse fires: high value, high risk
Industrial facilities account for approximately 25% of all UK workplace fires — the highest proportion of any sector category — equivalent to around 1,656 fires in 2024/25. The combination of large floor areas, dense combustible storage, high racking and intensive electrical loads means warehouse fires can grow far beyond the scale of a typical commercial blaze.
The economic stakes are equally significant. Preventable warehouse fires have been specifically linked to £1 billion in GDP losses and 5,000 job losses over a five-year period in the UK. For an individual operator, the consequences of a single serious fire can be terminal.
Warehouse fire causes
The fire risk profile of a warehouse differs markedly from other commercial environments. The main causes are:
- Electrical distribution failures. The leading identifiable workplace fire cause (around 18% nationally), and a particular concern in warehouses because of extensive conveyor systems, heavy lighting and heating demands, battery-charging banks for electric forklifts, and increasingly, electric vehicle charging infrastructure.
- Hot work. Welding, cutting and grinding create sparks that can ignite combustible materials over considerable distances. Hot-work permit systems are the critical control. Hot work caused over 180 fires nationally in 2024/25.
- Forklift trucks and battery charging. Conventional charging generates hydrogen gas in poorly ventilated areas. Lithium-ion equipment introduces thermal runaway risk — fires that begin inside the battery, resist suppression and can reignite after apparent extinguishment.
- Arson. Warehouses remain frequent deliberate-fire targets because of open-sided storage, perimeter vulnerabilities and large volumes of combustible goods. Physical security and material management are the primary controls.
- Goods in storage. Aerosols, solvents, chemicals, timber, paper, textiles and plastics each burn differently and need to be individually assessed and managed.
Why warehouse fires are so costly
Several structural characteristics make warehouse fires particularly expensive:
- Scale. Modern distribution warehouses are among the largest buildings in the UK building stock. Without adequate compartmentation or suppression, a fire can expand rapidly to enormous proportions.
- Racking and vertical fire spread. High-bay systems reaching 20–30 metres create vertical pathways that allow fire to advance faster than manual suppression can respond.
- Value density. A single distribution centre may hold tens or hundreds of millions of pounds in stock concentrated in one space.
- Business interruption. Fires disrupt entire supply chains — customers face shortages, contracts fail, supplier relationships suffer and lost revenue during reconstruction can exceed the physical losses.
- Suppression challenges. Many warehouse fires cannot be tackled by employees with portable extinguishers; only automatic suppression systems such as sprinklers are effective at the scale and speed at which these fires develop.
UK businesses claim around £940 million a year in fire property insurance, and the estimated average cost of a major fire is £657,074. Warehouses that do not recover within one month of a serious fire face an 80% chance of permanent closure.
| Measure | Figure |
|---|---|
| Share of UK workplace fires in industrial premises (2024/25) | ~25% (~1,656 fires) |
| GDP / jobs linked to preventable warehouse fires (5 years) | £1bn / ~5,000 jobs |
| UK business fire property insurance claims (annual) | £940 million |
| Average cost of a major fire | £657,074 |
| Electrical distribution faults as a share of workplace fires | 18% |
| Hot-work fires nationally (2024/25) | Over 180 |
| Satisfactory fire safety audits, England (2024/25) | 58% |
The sprinkler gap
The UK has one of the lower sprinkler installation rates in warehouse buildings among developed nations. Sprinklers activate automatically, target the seat of the fire, and suppress or control it before it becomes unmanageable.
The evidence is compelling: buildings with working sprinkler systems very rarely suffer fire deaths, and fire losses in sprinklered buildings are a small fraction of equivalent losses in unsprinklered buildings. Despite this, many UK warehouses — particularly older facilities and those occupied by smaller enterprises — have no sprinkler system. Retrofitting cost is the most-cited barrier, but the cost-benefit analysis against an average major fire loss of £657,074 is straightforwardly positive for most warehouse operators.
Legal obligations for warehouse fire safety
Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person for a warehouse must:
- Carry out a suitable and sufficient fire risk assessment addressing warehouse-specific hazards.
- Put in place and maintain appropriate fire precautions — detection systems, suppression systems, escape routes and fire doors.
- Provide fire safety information and training to all employees.
- Designate and train fire marshals proportionate to the scale and occupancy of the premises.
- Keep records of all fire safety activities and equipment testing.
Additional requirements apply under the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) for warehouses storing certain categories of hazardous goods. In England in 2024/25, only 58% of fire safety audits were judged satisfactory — a reminder that competent, well-trained fire marshals are central to compliance.
