Water saving tips

From our morning shower to brushing our teeth at night, it’s easy to assume that water will always be there when we need it. In a rainy place like the UK, it can sometimes feel as though water is endless – but this isn’t the case.

Every drop counts

Our world is changing, and we need to change with it to protect our most precious resource. Unpredictable weather and a growing population mean it’s important we work together to save water where we can.

Saving water could help you save money on your bill too – even more reason to check out our water saving tips, and make every drop count.

Take shorter showers

On average, a shower uses 10 litres of water a minute. That means a 10-minute shower can use 100 litres of water.

If a family of four reduced their shower time by just one minute, they could save:

  • £45 on metered water bills
  • Up to £52 on energy bills
  • As much as 11,648 litres of water a year

Why not see how much water and money taking shorter showers could save you with our water-saving calculator?

Turn off the taps

A running tap can use six litres of water a minute. Turning off taps when not in use is a really simple way to save water at home. By turning off the tap just five seconds sooner, you’ll save half a litre! Try not to keep it flowing when you’re doing the washing up or brushing your teeth.

Fill your dishwasher and washing machine

Save water, electricity, and dishwasher tablets by only starting the dishwasher once it’s fully loaded.

The same goes for the washing machine – fully loading your washing machine every time can save up to 4,000 litres a year.

Go green in the garden

Whether it’s skipping the car wash or turning off the hose, there’s loads you can do to save water outdoors. Your plants and lawn don’t need drinking quality water – in fact, they often prefer rainwater. Capturing rain with a water butt is a great way to save water and keep your garden looking lush at the same time.

Fix leaky loos and dripping taps

A leaky loo can waste an average of around 400 litres of water a day. That's equal to five full bathtubs. It’s easy to check whether you have a leaky loo. Just:

  • Wait for 30 minutes after flushing and then wipe the back of the pan dry with toilet paper.
  • Place a new, dry sheet of toilet paper on the back of the pan. Leave it there for up to three hours without using the toilet (it might be best to do this overnight).
  • If the paper is wet or torn, you have a leaky loo. 

Leaky loos are usually caused by a faulty flush valve or fill valve inside your tank.

How to check your flush valve

Mark the water level inside your tank and pop back 10 minutes later. If the water level has dropped, you’ll know the flush valve is the problem.

How to check your fill valve

If you can, look to see if any water is running into the overflow tube inside your toilet tank. If your tank takes a long time to refill or your flush isn’t as powerful as normal, that could also be a sign your fill valve isn’t working properly.

What we’re doing

In warmer weather, demand for our water increases. While we have enough water to go around, it can be challenging to pump, clean and deliver it quickly enough.

We’re working hard to ensure our network is in the best condition to deal with demand all year round. We've invested more than £1 million every day to protect pipes and predict and prevent problems before they happen. In 2020-21, our teams fixed over 60,000 leaks on our network. Learn more about how we’re tackling leaks.

If your pressure drops or water stops

At peak times of the day, you may notice your water pressure is lower. This can happen when water’s in high demand, and it should return to normal within a couple of hours. If your water stops completely, please check for the latest updates. If you or someone you know needs water to manage a medical condition, please let us know so we can provide extra support.
