UK construction sites are required by health and safety regulations to use 110v centre-tapped earth (CTE) power supplies rather than standard 240v mains. This dramatically reduces the risk of electrocution from faulty equipment on site. Most standard water coolers and dispensers run on 240v and are not suitable for direct connection to site power.
Culligan’s construction site water coolers are compatible with both 110v and 240v power supplies, meaning they work directly from the yellow site transformers found on virtually every UK construction site without any adaptation. Bottled models also require no water connection, so they can be positioned anywhere on site – on the floor, in a portakabin, in a welfare unit or next to a work area – wherever your team needs them most.
All models are available on flexible rental contracts or to purchase outright. Bottled models require no plumbing and are compatible with 110v site power on qualifying models.
Every UK construction site uses 110v yellow transformer power. Culligan’s water coolers for building sites are built to work on 110v as standard, so there is no need for step-up transformers, adaptors or workarounds. Plug into the site board and your team has chilled water immediately. It is one less thing to sort out on a busy site setup.
On most construction sites – particularly in the early stages of a build – there is no mains water connection available. Culligan’s bottled water coolers require only a power supply. Bottles are delivered on a schedule by Culligan’s delivery team, so your site always has water without anyone needing to manage the logistics. Empty bottles are collected on delivery, so there is no waste accumulation on site.
Construction projects rarely run to a fixed calendar. Culligan’s rental plans include short-term contract options specifically designed for project-based work, so you are not locked into a 12-month agreement for a six-month build. When the project finishes, the contract ends. If the project extends, extending your plan is straightforward.
Under CDM regulations and general health and safety requirements, construction sites are required to provide adequate supplies of clean drinking water for all workers. Culligan’s construction site water coolers meet these requirements as standard, providing clean, filtered and temperature-controlled water in a format that can be positioned anywhere on site, regardless of how the welfare facilities are configured.
Construction sites have several distinct areas where workers need access to drinking water. Here are the most common placements.
Running a bottled water cooler on a construction site means someone needs to manage the bottle supply. With Culligan’s bottled water delivery service, that is taken care of. We deliver fresh 19L or 11L water cooler bottles to your site on a schedule based on your team size and usage, and collect empties on every delivery. There is nothing for your site team to organise.

Yes, UK construction sites use 110v centre-tapped earth power supplies as required by health and safety regulations. Standard household or office appliances that run on 240v mains cannot be directly connected to site power. Culligan’s construction site water coolers are compatible with both 110v site power and 240v mains, so they work directly from the yellow site transformer boards found on virtually every UK construction site. No adapters or step-up transformers are required.
No. Culligan’s no mains water coolers are bottled models, they use standard 19L or 11L water cooler bottles rather than connecting to a water supply. This means they can be positioned anywhere on site with access to a power outlet, regardless of whether mains water has been connected. Bottles are delivered and collected by Culligan on a scheduled basis, so there is nothing for the site team to manage.
Yes. Under the Construction (Design and Management) Regulations 2015 and the Workplace (Health, Safety and Welfare) Regulations 1992, construction sites are required to provide adequate supplies of clean, cool drinking water for all workers.

Culligan’s portable water coolers for construction meet these requirements by providing chilled, filtered water in a format that can be positioned anywhere on site.

When you set up your rental plan, we arrange a delivery schedule based on your team size and typical water consumption.
