How to cut your water bill

Water bills have been climbing, and unlike energy or broadband you can't switch supplier — so the savings come from paying for only what you use and using less of it.

Should you get a water meter?

If you don't have a meter, your bill is based on your home's rateable value — not how much water you actually use. A meter is usually free to install in England and Wales, and it often pays off for smaller households:

  • Single occupants, couples and small families in larger homes tend to save the most.
  • Ask your supplier for a free meter — installation is normally at no cost to you.
  • There's a safety net: if the meter leaves you worse off, you can usually switch back within the first 12 months.
  • Large families or homes with high water use (big gardens, lots of baths) may be better off unmetered — do the estimate first.

Use less, pay less

  • Fix dripping taps and running toilets — a constant drip wastes a surprising amount over a year.
  • Shorter showers beat baths for water use; even a minute less helps.
  • Only run the dishwasher and washing machine with full loads.
  • Use a water butt for the garden instead of the hosepipe.
  • Turn the tap off while brushing teeth — it's pure waste otherwise.

Help with water bills

  • If you're on a water meter and receive certain benefits, the WaterSure scheme caps your bill.
  • Most suppliers run social tariffs or support schemes that cut bills for low-income households — ask yours directly.
  • Struggling to pay? Contact your supplier early to arrange a payment plan rather than letting arrears build up.

Frequently asked questions

How do I know if a water meter would save me money?

As a rough rule, if there are fewer people in your home than bedrooms, a meter usually wins. Most suppliers have an online calculator — or just ask them.

Is installing a water meter really free?

In most cases yes, in England and Wales, when requested by the bill payer. Your supplier will confirm before booking the work.

Can I switch water supplier like I can with energy?

No — households can't choose their water supplier; it's set by where you live. That's why meters and cutting usage are your main levers.

What is WaterSure?

A scheme that caps metered water bills for eligible households on certain benefits, including families with three or more children or someone with a medical condition needing extra water.
