A real flushing toilet, not a chemical portaloo
A welfare unit is a self-contained cabin with a private toilet and wash basin for people on site. It provides hygiene facilities without the need to build a permanent bathroom.
A basic portaloo is a single cubicle with a chemical tank and no running water. Our welfare units have insulation, lighting, power, a ceramic flushing toilet and a wash basin. They connect to mains water and waste.
Every unit arrives fully assembled. Position it, then have a plumber and electrician connect the water, waste and power. No on-site build is needed.
Every unit includes
- Ceramic flushing toilet and wash basin
- Pre-wired and pre-plumbed for mains water, waste and power
- Sensor-controlled LED lighting and ventilation
- Fully insulated, heavy-duty steel frame
- Brand new, never previously used
- UK-wide delivery or free Leicester collection
Welfare unit vs portable toilet: what's the difference?
A single cubicle with a chemical tank and no running water. Cheap and quick to place, but needs regular emptying by a service contractor and doesn't meet every site's welfare standard on its own.
Connects to mains water and waste, flushes like a normal toilet, and includes a wash basin with soap. The unit is insulated for winter use and has sensor-controlled lighting.
Where are welfare units used?
Construction sites
UK construction sites must provide welfare facilities. A pre-plumbed unit can be connected before work starts.
Cafés & food trucks
Mobile catering and outdoor cafés often trade with no nearby plumbing. A unit alongside gives staff and customers proper facilities on the spot.
Outdoor events & festivals
Self-contained units group together easily at festivals or show grounds with no permanent plumbing needed nearby.
Farms & rural sites
The insulated unit can be used through winter without running mains plumbing to a field or outbuilding.
Sports clubs & community events
Extra capacity for match days, tournaments or temporary clubhouses while permanent facilities are rebuilt or upgraded.
Do you need a welfare unit by law?
If you run a construction site in the UK, yes. Health and safety law requires sites to provide proper welfare facilities, including toilets and washing points for everyone working there. This is a legal requirement from the start of work, not only after the site is established.
Outside construction, a welfare unit isn't always a legal requirement, but it's often the practical choice anywhere people work or gather without a permanent bathroom nearby. If you're not sure what your site needs, your principal contractor or local authority can confirm the exact requirement.
Choosing the right welfare unit
Our double welfare unit has two separate cubicles for general site use. It is a common choice for construction crews and events where several people may need the facilities at once.
Our accessible welfare unit is a single wheelchair-accessible cubicle with a ramp and grab rails. Sites often order it alongside a double unit, so standard and accessible facilities are covered together. Neither quite fit your site? Get in touch and we'll talk through extra cubicles or reinforced accessibility features.
How much does a welfare unit cost?
Prices vary by size and spec. Our range starts at £2,999.99 for the double welfare unit and £2,999 for the accessible unit, both brand new, fully insulated and supplied ready to connect, with no extra fit-out costs once the unit arrives.
When comparing prices, check what's actually included. A cheaper shell that still needs plumbing, wiring or a wash basin fitted often costs more by the time it's usable. Ours arrive ready to plumb in and switch on.
Why buy your welfare unit outright
Buying a welfare unit means one purchase rather than recurring rental charges or return conditions. You can arrange its use around your site's schedule.
You can move an owned unit between sites, store it between jobs, or sell it later. This can make buying practical for projects that need welfare facilities for more than a few months.
Installation, delivery and connection
Every welfare unit arrives ready for use with little site prep needed. Each one is pre-wired and pre-plumbed for mains water, waste and electricity, so connection is a straightforward job for your plumber and electrician on delivery day.
We deliver nationwide, with cost quoted by postcode, or you can collect free from our warehouse in Leicester. Once connected, the sensor-controlled lighting and ventilation keep day-to-day upkeep down to routine cleaning.
How long does a welfare unit last?
A well-maintained welfare unit lasts for years, not months. The steel frame resists rust and the insulated panels don't rot or warp like timber can, so there's no repainting each season. Day-to-day upkeep is simple: clean the cubicles as you would any bathroom, and check the plumbing and electrics alongside the rest of your site equipment.
Welfare unit FAQs
Yes. UK health and safety law requires sites to provide toilets and washing facilities for everyone on site. These facilities must be available from the start of work.
