How to Choose the Right Business Water Supplier in the UK
The UK business water market was deregulated in 2017, allowing businesses to choose their water supplier rather than being assigned one. This means that instead of being stuck with one company, you can shop around and get the best deal—just like you would for your energy or internet provider.
When it comes to choosing the right business water supplier, several key factors should guide your decision. It’s not just about price. You need to look at customer service, billing accuracy, sustainability policies, added-value services, and how flexible their contracts are. You also want a supplier that understands your business size and needs—whether you’re a small café or a large manufacturing plant.
Let’s walk through everything you should consider so you feel confident when making your choice.
Key Factors to Consider When Choosing a Supplier
Cost and Tariffs
Water prices can vary depending on your region and usage, but each supplier can offer different tariffs and discounts. Look for:
- Fixed vs. variable pricing
- Volume discounts
- Bundled services (like wastewater)
Top Tip: Always compare quotes from at least three suppliers to get a better idea of value.
Billing Transparency
Clear and accurate billing is critical. A good supplier will:
- Provide easy-to-understand bills
- Offer online billing and payment tools
- Send regular usage reports
Choose a provider that lets you track and manage your usage online.
Customer Service
Customer support can make or break your experience. Look for:
- Fast response times
- Dedicated account managers
- Online support portals or live chat
Case in Point: A small hotel chain switched suppliers after repeated billing issues. Their new supplier offered 24/7 phone support, saving them time and frustration.
Contract Terms
Always check the terms and conditions. Key points include:
- Contract length (typically 1–3 years)
- Exit fees or penalties
- Renewal policies
A flexible contract is better if your business plans might change.
Sustainability and Ethics
Many businesses now prioritise sustainability. Some suppliers offer:
- Green water solutions
- Advice on reducing consumption
- Reports on your carbon footprint
Did You Know? Some suppliers use profits to support community water projects.
Extra Services
Some water companies go beyond just supplying water. These may include:
- Leak detection and repair
- Water efficiency audits
- Benchmarking reports
These extras can save you money in the long run.
Regulation and Licensing
Ensure your supplier is authorised by Ofwat, the official regulator. You can find a list of licensed suppliers on the Open Water website. Only choose licensed suppliers to protect your business.

Questions to Ask Before Signing a Water Contract
Before choosing your supplier, ask these:
- How do you handle billing disputes?
- What is your average customer satisfaction rating?
- What happens if I want to switch early?
- Do you offer services for multiple sites?
- How can I reduce my water usage with your service?
Asking these questions ensures you pick a supplier that aligns with your business needs.

Mistakes to Avoid When Choosing a Water Supplier
- Only focusing on cost – Cheapest isn’t always best.
- Ignoring contract details – Always read the small print.
- Not reviewing usage data – Pick a supplier that helps you manage water better.
- Overlooking customer reviews – Check Trustpilot and Google.
Example: A Small Café in Leeds Saves Big
A café in Leeds used 25m³ of water a month. By switching from their default regional supplier to Everflow, they cut costs by 12%, gained access to usage tracking online, and started receiving monthly efficiency tips—at no extra charge.
This shows that even small businesses can benefit from making a change.
Why Switching Suppliers Is Easier Than You Think
Changing suppliers might sound difficult, but it’s quite simple:
- Get a quote – Provide your recent water bill and usage.
- Review the offer – Check for hidden fees or extras.
- Sign the contract – Your new supplier handles the switch.
- Sit back – There’s no interruption in service.
No pipes or meters need to be changed—it’s an administrative change only.
