Water Saving Week 2025: Small Waste, Big Impact

Table of contents

Water usage in the UK continues to rise each year. Most of us use about 150 litres of water a day[1], the equivalent of nearly two full baths[2].

That’s why Waterwise is hosting its ninth annual Water Saving Week, from 12–16 May 2025. This year’s theme, “Small Waste, Big Impact,” encourages everyone to become a Water Saving Hero by making small changes that add up.

What do you do if you’re in water arrears[3]

You’re not alone. In March 2024, it was found that over 2.5 million households were reported to be behind on their water bills, owing an average of £822. While water companies in the UK can’t legally cut off your water if you miss a payment, it’s still important to stay on top of your bills.

How to save money on your water bill

The average annual water bill in England and Wales for 2025-26 is around £603[4], which is about £50.25 a month. While this will vary depending on your water provider, the number of people in your household and other factors, there are ways to save money on your bill:

Switch to a water meter[5]

You can save an average of £264 annually, and the installation is usually free. It can also reduce your water usage by up to 20%, saving money and the environment. Use the Consumer Council for Water’s calculator to see if you can save by switching to a meter.

Ask about support tariffs

Many water companies offer discounted tariffs and support schemes for those struggling to pay their water bills, including capping bills or offering payment plans.

Check with your water provider for eligibility and further details.

Check for extra help

If you’re having difficulty paying your water bills, you may be eligible for third-party deductions, where some of your water bills can be paid directly out of your benefits.

Use our benefits calculator to check your eligibility.

Easy ways to use less water

Save water when washing your clothes

Only putting the washing machine on when you have a full load maximises water efficiency and reduces the number of washes you need to do. A full load uses less water per item, so it’s a smart way to save.

Many machines also offer water-saving cycles, using less water and energy while keeping your clothes clean.

Consider your dishwasher usage

Like with the washing machine, always wait for a full load before running your dishwasher. Most modern dishwashers are water-efficient but designed to work best when packed to capacity.

They’re also powerful enough to clean dishes without needing a pre-rinse. Scrape off large food scraps, but let your dishwasher do the rest.

Check if your machine has a water-saving mode, too.

Keep an eye on your tap usage

Turn off the tap while brushing your teeth or washing dishes. A running tap wastes over six litres per minute[6], so every second counts.

Installing a low-flow aerator is an easy way to make your taps more efficient. It reduces water flow without sacrificing water pressure.

Cut down your shower time

Set a timer or play your favourite song to reduce your shower time – every minute saved helps lower your bill.

Find and fix sneaky leaks

Regularly inspect your taps, pipes and toilets for any signs of leaks. Even small, slow leaks can waste litres of water over time. To check if your toilet is leaking, drop a few drops of food colouring in the cistern and wait 15 minutes. If the colour appears in the bowl, you have a leak that needs fixing.
