Construction Site Welfare Facilities: What Must Be Provided?

Everyone working on a construction site must have access to suitable and sufficient welfare facilities. The arrangements should cover toilets, washing, wholesome drinking water, changing and storage where required, and somewhere suitable to eat and rest. The exact provision depends on the workforce, work, location and duration—but it must be ready from day one, not promised for later.

Schedule 2 of the Construction (Design and Management) Regulations 2015 sets the minimum welfare requirements for construction sites. HSE explains that the Principal Contractor should ensure suitable facilities are available from the start of a project until it finishes, while contractors must provide suitable welfare for workers under their control.

No grace period

A site cannot lawfully treat missing welfare as a snag to resolve after mobilisation. Access to basic welfare needs to be part of the pre-start arrangements and remain effective as the site layout, workforce and work activities change.

Who is responsible for construction welfare?

Duty holder	What the role should do	Practical evidence
Commercial client	Make suitable project-management arrangements, including ensuring the construction phase can be carried out with facilities that meet Schedule 2.	Pre-construction information, programme allowance, site constraints and confirmation that welfare can be installed or accessed.
Principal Contractor	Ensure suitable welfare is provided for the construction phase, from the start of the project until completion, and coordinate arrangements shared by contractors.	Mobilisation plan, site layout, servicing arrangements, inspections and changes as the workforce or site moves.
Contractor	Provide suitable welfare for workers under its control and cooperate with the Principal Contractor's site arrangements.	Worker numbers, task-specific washing or shower needs, mobile arrangements and reported defects.
Workers and supervisors	Use the facilities correctly and report missing supplies, cleanliness problems, damage or access difficulties.	Briefings, defect reports and prompt close-out records.

On a single-contractor project, the contractor will usually control the construction phase arrangements. On a project involving more than one contractor, the Principal Contractor has the coordinating role. Contracting the cleaning or hire of welfare units to a supplier does not remove the duty to make sure the facilities remain suitable and available.

What is the minimum welfare provision?

Facility	Core requirement	Points to test before work starts
Toilets	Suitable, sufficient, readily accessible, ventilated, lit and kept clean and orderly.	Workforce size and mix, location, drainage or tank capacity, servicing and supplies.
Washing	Facilities near toilets and changing areas, with clean hot and cold or warm water, soap and hygienic drying; showers where the work or health reasons require them.	Whether workers can wash hands, face and forearms properly and whether hazardous contamination needs separate or enhanced facilities.
Drinking water	An adequate supply of wholesome drinking water at readily accessible and suitable places, with cups unless a drinking jet is provided.	Potability, labelling where necessary, replenishment and protection from contamination.
Changing and storage	Suitable changing rooms where special clothing is required and workers cannot change elsewhere; secure facilities for personal and work clothing and provision to dry wet clothing.	Privacy, seating, security, separation where needed and capacity to dry clothing between shifts.
Rest and meals	Suitable and sufficient rest rooms or rest areas with tables and seats with backs, arrangements for meals and means to boil water.	Heating or cooling, cleanliness, separation from contamination and enough space for expected breaks.

“Suitable and sufficient” is not satisfied by listing a cabin on a drawing. The facilities must work for the people and activities actually on site. The arrangement should also provide appropriate rest facilities for pregnant women and nursing mothers when required.

Are chemical toilets and hand sanitiser enough?

HSE says flushing toilets should be provided where possible. Portable chemical toilets can be acceptable where flushing facilities cannot be provided, including at the beginning or end of some projects and on temporary or remote sites. They still need suitable lighting, ventilation, cleaning, servicing, toilet paper and convenient access.

A small basin or hand sanitiser inside a portable toilet is not automatically adequate. Washing facilities should allow workers to wash their hands, face and forearms properly, with clean hot and cold or warm running water, soap and suitable drying. Where a compact toilet does not provide this, suitable additional washing facilities must be nearby.

Showers are not required on every site. They are required where the nature of the work or health reasons make them necessary. Work involving contaminants such as cement, lead or harmful micro-organisms may require additional facilities and careful separation of washing from eating and rest areas.

There is no single CDM Schedule 2 ratio that makes every arrangement compliant. HSE provides indicative guidance for numbers, including guidance relevant to portable chemical toilets, but the final provision still needs to be suitable for the workforce, usage pattern, servicing frequency and mix of users.

What should the rest, eating and changing areas include?

Workers need a clean area where they can sit, eat and take breaks away from work hazards and contamination. Schedule 2 requires sufficient tables and seats with backs for the number likely to use the space at one time, suitable arrangements for preparing and eating meals where food is regularly eaten on site, and a means to boil water.

The area should be maintained at an appropriate temperature, with reasonable heating in cold conditions and ventilation in hot conditions. Drinking water needs to be wholesome and readily accessible. Storage and meal areas should not expose food, cups or personal items to dust, chemicals or contaminated clothing.

Changing rooms are required where workers must wear special clothing and cannot, for health or propriety reasons, be expected to change elsewhere. There should be seating and secure storage, with arrangements to separate work and personal clothing where needed and to dry wet workwear.

Can a site use a café, occupied building or shared facilities?

Existing facilities can sometimes form part of the solution, but they should not simply be assumed to be available. HSE says the site needs a proper agreement with the owner, access whenever workers are on site and arrangements for cleaning and replacing soap, towels, toilet paper and other consumables.

The journey also matters. Facilities should be positioned so workers can reach them quickly and safely. Large or moving sites may need satellite toilets or welfare units because one central compound is too far from the workface. For highway, utilities, repair and other mobile work, the arrangement should account for journey time, traffic, the duration of the task and any hazardous substances.

A mobile welfare unit can be a practical solution, but being mobile does not lower the minimum standard. It still needs to provide the required washing, toilet, changing, eating and rest functions for the work and workforce it supports.

How should welfare be sized, checked and maintained?

The welfare plan should be based on the maximum expected workforce and the way people will use the facilities, not only the first-day headcount. Consider shift patterns, male and female workers, visitors, disabled access, remote workfaces, cleaning intervals, waste capacity and the time needed to replenish water and consumables.

Schedule 2 permits toilets to be used by both men and women where each convenience is in a separate room with a door that can be secured from the inside. Otherwise, separate use must be provided. Similar privacy and suitability considerations apply to changing arrangements.

A named person should check cleanliness, temperatures, lighting, ventilation, water, drainage or tanks, consumables, drying arrangements and access. The frequency should reflect actual usage and conditions; a daily clean may not be enough on a busy or dirty site.

Welfare also needs to move with the project. When cabins are relocated, services isolated, workforce numbers increase or hazardous work begins, the Principal Contractor should revisit the arrangement and update the Construction Phase Plan where the change affects the site-management arrangements.

Pre-start welfare planning checklist

Forecast the workforce, shift pattern, project duration and remote work areas for each phase.
Confirm who will provide, install, service, clean, inspect and replenish every facility.
Check water, drainage, power, heating, ventilation, lighting, waste and safe access.
Match washing and shower provision to substances, dust, biological risks and dirty work.
Provide suitable toilets and privacy for the expected workforce, including secure single-user rooms or separate arrangements as required.
Separate eating and rest areas from contamination and provide drinking water, seating, tables and a means to boil water.
Plan changing, secure storage and drying for work clothing and personal items.
Document any agreement to use existing or third-party facilities and verify opening hours, access and maintenance.
Inspect the provision before mobilisation and include it in routine site inspections and corrective-action tracking.
Review the arrangement when the site layout, work, workforce or programme changes.
