Warehouse Line Marking Regulations UK
There is no single prescriptive colour standard in UK law, but clear, consistent and well-maintained markings are a legal expectation under HSE workplace transport guidance.
Facilities managers, H&S leads and warehouse operators.
What The HSE Says
UK law does not mandate one fixed colour scheme for floor markings. Instead, the Workplace (Health, Safety and Welfare) Regulations 1992 and HSE guidance (notably HSG136, Workplace transport safety) require that traffic routes are suitable, clearly indicated and kept free from obstruction. Markings must be visible, durable and maintained.
Understanding Warehouse Colour Coding
While not legally prescribed, most UK warehouses adopt a consistent colour convention so that staff and visitors instantly understand each zone:
- White or yellow: general aisle and storage demarcation
- Yellow: pedestrian walkways and vehicle routes
- Red: hazards, defective areas and items not to be moved
- Green: safety equipment, first aid and PPE points
- Blue / black-and-yellow hatching, keep-clear and no-go zones
Pedestrian Routes
Pedestrian walkways should be continuous, wide enough for the expected footfall, and lead people safely from entrances to their work areas without unnecessary crossing of vehicle routes.
Forklift Routes
Vehicle routes must accommodate the largest vehicle in use, with adequate clearance, clear sightlines and controlled crossing points where they meet pedestrian routes.
Emergency Escape Routes
Escape routes and the areas in front of fire exits, extinguishers and assembly points must be permanently kept clear and clearly marked, typically with green markings or hatching to prevent obstruction.
Common Compliance Mistakes
- Faded or worn markings that are no longer clearly visible
- Inconsistent colours across different parts of the site
- Walkways that route pedestrians through high-risk vehicle areas
- Obstructed fire exits and emergency equipment zones
- Markings not updated after racking or layout changes
When To Refresh Markings
Markings should be inspected regularly and refreshed before they degrade to the point of being unclear. High-traffic forklift routes wear fastest. As a rule of thumb, review markings at least annually, and always re-mark after any layout, racking or process change.
