Commercial kitchen hand-wash basin requirements in the UK.
A hand basin is a food-safety control, not just a plumbing fixture. This guide explains what UK food premises need to provide, where handwashing facilities should be located and the common mistakes that make them ineffective.
Practical guidance from TKEG (The Kitchen Efficiency Group), built around everyday UK hospitality compliance and kitchen operations.
What does a commercial kitchen need for handwashing?
UK food-hygiene rules require an adequate number of washbasins, suitably located and designated for cleaning hands. They must have hot and cold running water, materials for cleaning hands and a hygienic means of drying them.
The key test is whether staff can wash their hands properly at the points in the operation where handwashing is needed, without creating contamination risk.
How many hand-wash basins are required?
There is no universal rule saying every kitchen needs exactly one basin per a fixed number of staff. The legal wording is an adequate number, so the right provision depends on the size, layout, staffing and food-handling activities of the business.
A single basin can be inadequate where staff would need to cross contaminated areas, leave a preparation room or queue during busy service before washing their hands.
Where should the basin be located?
Handwashing facilities should be suitably located so staff can use them when needed. FSA cross-contamination guidance also says washbasins should be positioned to avoid splashing contaminating ready-to-eat food.
In practice, the route between raw-food handling and ready-to-eat work is particularly important. A hand basin that is technically present but inaccessible or routinely blocked is not an effective control.
Can a food-preparation sink double as a hand basin?
Where necessary, facilities for washing food must be separate from handwashing facilities. Using the same sink for hands, food and equipment can create contamination and availability problems.
A designated hand basin should remain available for handwashing and should not become storage space for utensils, containers or cleaning equipment.
What should be provided at the basin?
Disposable paper towels are a common hygienic drying method. Whatever system is used should not create a new contamination risk or routinely leave staff unable to dry their hands effectively.
Do taps matter?
Taps and handles can become contaminated after raw-food handling. FSA cross-contamination guidance notes that staff should avoid recontaminating clean hands when turning taps off.
Businesses can manage this through suitable tap design or a safe procedure, such as using a disposable towel to operate a conventional tap after washing where appropriate.
What about mobile and temporary catering?
Mobile and temporary food premises still need appropriate facilities to maintain adequate personal hygiene, including hygienic handwashing and drying. The exact setup can differ from a permanent kitchen, but it must work reliably during operation.
Water supply, waste-water collection, soap and drying materials all need to be planned before service starts rather than improvised once staff are handling food.
What should managers check each day?
Opening checks can provide useful evidence that facilities were available, but the priority is fixing a failed handwashing facility promptly.
How TKEG supports handwashing-facility evidence
TKEG can include handwashing-facility checks within opening, closing, cleaning, maintenance and corrective-action workflows so managers can show both the routine check and what happened when a facility failed.
Practical guidance, checked against official UK sources.
TKEG guidance is written for practical hospitality use. Where a topic involves regulation, official schemes or workplace safety, businesses should also consult the current guidance from the relevant authority and apply it to their own operation.

Common questions
How many hand-wash basins does a commercial kitchen need?
There is no single fixed number for every kitchen. UK rules require an adequate number, suitably located for the size, layout and activities of the food business.
Does a hand-wash basin need hot and cold water?
Yes. Handwashing basins must have hot and cold running water, or an appropriately mixed supply, together with hand-cleaning materials and hygienic drying.
Can staff wash their hands in the food sink?
Handwashing facilities should be designated for hands, and where necessary food-washing facilities must be separate. A dedicated hand basin is the appropriate control in a commercial food-preparation environment.
Can a hand basin be in another room?
It must be suitably located for the operation. If staff cannot wash their hands promptly at the points where contamination risk changes, the provision may not be adequate.
Do food trucks need a handwashing sink?
Mobile and temporary food premises must have appropriate facilities for hygienic handwashing and drying where necessary. The setup can differ from a permanent kitchen but still needs a reliable water supply and suitable waste-water arrangements.
