Running a business in the UK comes with many expenses — but few realise how complicated and unexpected business water charges can be. Whether you’re managing a small retail unit or a multi-site operation, understanding your water bill can lead to significant savings and smarter utility decisions.
Here are six unexpected facts about business water charges that every UK business owner should know.

1. You’re Not Stuck with One Water Supplier
Many businesses in England still believe they can’t switch water suppliers — but the water retail market was deregulated in April 2017. This means eligible businesses, charities and public sector organisations can shop around for better deals.
Why it matters: You could save up to 20% on your water bills by switching to a more competitive provider.
2. You’re Paying for Wastewater Twice
Your business pays two charges related to water:
- Water usage (incoming)
- Wastewater or sewerage (outgoing)
The latter is often calculated based on your incoming water, meaning even small leaks or excessive consumption can lead to higher wastewater charges, even if the water isn’t actually being discharged.
3. Standing Charges Vary Widely
Aside from usage, your water bill includes a fixed standing charge — and this varies drastically between suppliers and regions.
Tip: Some suppliers charge more for administrative costs and meter maintenance than others. Comparing these could uncover hidden savings.
4. You May Be Overcharged Due to Incorrect Banding
Your business’s charges are partly based on the type of premises and rateable value. If this classification is outdated or inaccurate, you could be overpaying significantly.
Action: Ask your supplier or broker to reassess your site’s classification — or request an audit from a water expert.

5. Leakage on Your Property = Your Responsibility
Water lost due to leaks within your boundary is your cost to bear — not your supplier’s. This can quietly inflate your bill.
Solution: Regularly monitor your meter for unusual spikes, and consider leak detection services for peace of mind.
6. Trade Effluent Can Trigger Special Charges
If your business produces contaminated water — for example, from food processing or car washing — you’re likely producing trade effluent. This requires a permit and comes with additional fees and compliance regulations.
Don’t ignore this: Non-compliance can result in penalties or legal action.
