10 Ways UK Businesses Can Save Money on Water Bills

Water is a vital resource for every business, but water bills can be complex and sometimes confusing. Many UK businesses could be paying more than necessary due to errors, inefficiencies, or simply not knowing the options available. This guide explores 10 practical ways your business may be able to save money on water bills, reduce unnecessary charges, and ensure you are only paying for what you use.

1. Review Your Business Water Bill in Detail

Start by carefully checking your most recent water bill. Look out for estimated readings, unfamiliar charges, or sudden changes in usage. Understanding each line item is vital. A business water bill audit can help you better understand your charges and spot possible issues that may otherwise go unnoticed.

2. Check for Billing Errors and Overcharges

Errors can occur at any stage, from meter reading to tariff application. These mistakes may result in your business being overcharged. Reviewing your bills for historic errors could reveal discrepancies. Find out more about how to identify water bill overcharges and what steps to take if you think you’ve been billed incorrectly.

3. Monitor Water Consumption and Spot Anomalies

Regularly tracking your water use helps highlight unexpected increases, which may be a sign of leaks or inefficiencies. Compare your bills month-on-month and look for unexplained spikes. A professional consumption and leak anomaly check can support this process and help prevent wastage.

4. Understand Your Tariff and Standing Charges

Water retailers apply different tariffs and standing charges based on business size, location and usage profile. Reviewing your current tariff could reveal opportunities for change. In England, most businesses can choose their water retailer, so comparing tariffs might help. For guidance, see Open Water or speak to your current supplier about available tariffs.

5. Investigate Surface Water Drainage Charges

Many businesses pay for surface water drainage, but not all properties contribute surface water to public drains. Double-checking the basis for these charges could reveal if you are eligible for a different charging band or removal of the charge. Learn more about surface water drainage charges and how to ensure you’re being billed correctly.

6. Assess Wastewater and Sewerage Charges

Wastewater charges are typically based on the assumption that most incoming water leaves via the sewer. If your business uses water in processes where it does not enter the sewer (for example, in manufacturing or irrigation), you may qualify for a reduced charge. For further information, see our guide to wastewater charges.

7. Audit Water Usage Across Multiple Sites

Multi-site businesses often receive consolidated water bills. It’s important to check each location’s consumption and charges, as errors or inefficiencies at one site can be overlooked. A multi-site water bill review can help identify anomalies and ensure consistency across your portfolio.

8. Address Leaks Quickly

Even minor leaks can result in significant costs over time. Establish regular maintenance and checks of your business premises for leaking taps, toilets, or underground pipes. Promptly addressing leaks could prevent both higher bills and potential property damage.

9. Educate Staff on Water Efficiency

Raising awareness among employees is one of the most effective ways to reduce unnecessary water use. Simple measures like reporting leaks, switching off taps, and using equipment efficiently can make a difference. Consider displaying water-saving tips and providing regular training.

10. Consider Your Options for Switching Supplier

In England, most non-household customers can choose their water retailer. Switching may result in access to better tariffs, improved customer service, or tailored solutions. However, the market in Scotland operates separately, and in Wales, only businesses using 50 megalitres or more per year have the right to switch. Before making any changes, thoroughly research your options and refer to Ofwat for regulatory information.
