Warehouse flooring in the UK must meet strict health, safety, and structural regulations. From slip resistance and load capacity to fire spread and durability, compliance is critical not only for safety but also to pass inspections and avoid liability.
Multiple bodies set and influence warehouse floor requirements, including the Health and Safety Executive (HSE), Building Regulations, and British Standards. This guide breaks down what is expected for commercial and industrial floor slabs in terms of performance, safety, and inspection readiness.
Under the Workplace (Health, Safety and Welfare) Regulations 1992, floors must be suitable, in good condition, and free from hazards. Regulation 12 specifies that flooring must be even, stable, and provide adequate grip. Slip resistance is critical in areas with foot traffic, loading bays, and where liquids may be present. Employers are required to assess floor safety under risk assessments and implement anti-slip measures if surfaces pose a risk when wet, dusty, or contaminated. Non-compliance can lead to HSE enforcement action or claims under duty-of-care laws.
Warehouse floors fall under Approved Document A (Structure) and B (Fire Safety) of the Building Regulations. Concrete slabs must be designed to support dead loads (rack systems, mezzanines) and imposed loads (forklifts, palletised goods) with appropriate margins of safety. Approved Document B also requires floors to meet fire resistance durations, often 60 to 90 minutes in larger storage buildings. Floor slabs may also need compartmentation or non-combustible surfaces in high-risk areas. Structural engineers must sign off on floor spec and detailing before final approval.
Although not legally mandated, the HSE recommends using the Pendulum Test to evaluate slip risk. In practice, this means warehouse floors should achieve a PTV (Pendulum Test Value) of at least 36 in both dry and wet conditions. Floors with lower scores may be classed as high risk. Pendulum testing is commonly required during handover of new-builds or refurbishments. For resin systems, R ratings (e.g. R10 to R13) may also be specified in design documentation or risk assessments to ensure adequate traction in operational zones.
BS 8204 (Parts 1–7) sets out standards for screeds, toppings, and concrete slabs in commercial environments. It covers flatness tolerances, surface regularity, curing requirements, and how to manage movement joints. BS EN 1992 (Eurocode 2) is the structural concrete code, used for reinforcement design, thickness calculation, and load distribution. These are typically followed by engineers during design but should also be checked by main contractors and flooring installers to ensure build compliance and long-term durability.
HSE guidance on traffic management requires warehouses to clearly separate pedestrians from vehicles. This includes floor markings for walkways, crossings, exclusion zones, and loading areas. While not a building regulation, it is a legal expectation under PUWER and workplace safety law. Anti-slip coatings, line striping, and colour zones must be maintained and clearly visible at all times. Damaged or faded markings are a compliance issue and a safety risk. Some insurers may require regular re-striping and floor signage inspections to maintain coverage.
Once installed, warehouse flooring becomes the employer’s responsibility under Regulation 5 of the Workplace Regs 1992. This includes ensuring the floor is kept clean, hazard-free, and maintained in a safe condition. Any damage, cracking, delamination, or uneven wear must be repaired promptly. Visual inspections should be carried out at least weekly, and formal inspections documented monthly. New construction or replacement slabs must also meet Part L (thermal performance) if part of a wider energy compliance package for heated warehouses.
