Rules for Toilets and Washing Facilities

What the law says about workplace toilets and washing facilities

Employers in the UK must provide toilet and washing facilities for their workers. This sits within a broader duty to provide welfare facilities, which also includes rest areas, drinking water, and somewhere to store clothing. The rules apply to almost all workplaces: offices, shops, factories, and construction sites.

The main law is the Workplace (Health, Safety and Welfare) Regulations 1992, which operates under the Health and Safety at Work etc. Act 1974. The 1992 regulations set minimum standards; the 1974 Act establishes the overarching duty on employers. The Health and Safety Executive publishes guidance on compliance.

Employers must provide suitable facilities from day one, whether staff work full time, part time, or on temporary contracts. Self-employed people working alone from home are not covered by the 1992 regulations for their own workspace, though they still have duties under the 1974 Act. If they share a workspace with others, the 1992 regulations usually apply.

Basic requirements for toilets and washing facilities

Toilets must be suitable and sufficient for the people using them. There is no single set number for every workplace: the right provision depends on shift patterns, the nature of work, and building layout. Check the HSE website for recommended ratios.

Toilets should be connected to suitable drainage, flushing, provided with toilet paper, adequately lit, ventilated, and kept clean. Separate facilities for men and women are required unless each toilet is in a private, lockable room for one person. In smaller workplaces, a single lockable toilet may be acceptable. Toilets should not open directly into rooms where food is prepared or eaten.

Employers must also provide washing facilities: basins with hot and cold running water, soap, and a way to dry hands. Paper towels, roller towels, or hand dryers are all acceptable. Where workers handle hazardous substances or do dirty work, showers may also be needed.

Washing facilities should be near the toilets. Workers should not have to walk long distances or go outside to wash their hands. Like toilets, washing areas must be kept clean and maintained. A basin with no soap or broken taps does not meet the legal standard. Employers should establish regular cleaning schedules and a clear system for reporting problems.

Difficult circumstances and alternative solutions

The regulations recognise that full facilities are not always straightforward to provide. Older buildings may have limited space or plumbing; remote sites might lack mains water or drainage.

In these situations, employers may use portable or chemical toilets on construction sites or temporary locations. Mobile washing units may work where permanent facilities are not practical. However, cost alone is not a valid reason to avoid the requirement. Employers must take practical steps that balance welfare regulations against genuine physical or logistical constraints.

If permanent toilets are genuinely impossible, employers should document why and show what alternatives they have arranged. The HSE may take enforcement action if workers lack reasonable access. For short term work lasting only a few days, employers still need some form of provision. Workers cannot be expected to go without toilet access during a working day.

Cleanliness, maintenance, and accessibility

Facilities must be kept efficient, in good repair, and clean. This means regular cleaning, prompt repairs, and restocking of soap and paper. Workers should have a way to report issues, and problems should be fixed without unreasonable delay.

Workers with disabilities must be able to use the facilities. This may require accessible toilets with more space, grab rails, and appropriate door widths. The Equality Act 2010 places duties on employers to make reasonable adjustments, extending to toilet and washing provision. Employers should check that any accessible toilets in shared buildings are genuinely available to staff.

Toilet and washing areas should not be excessively cold. Workers are entitled to reasonable conditions, particularly during winter.

The Health and Safety Executive website has detailed guidance on workplace welfare facilities, including numbers, layouts, and standards. The Equality and Human Rights Commission provides guidance on employer duties under the Equality Act 2010.

If your employer is failing to provide adequate facilities, raise the issue with them first and keep a record. If the problem continues, contact the HSE or your local authority environmental health department. Trade unions can also advise members and raise concerns on your behalf. GOV.UK provides links to current legislation and enforcement bodies.
