How we bill you if you have a meter

Every six months, we’ll send you a bill that covers the supply of clean water and the treatment of wastewater.

Your bill will show charges for every cubic meter (m3) of water that’s used. One cubic meter equals 1000 litres. That’s about 25 quick showers.

For each cubic meter, we charge 148.28p for water and 90.51p for wastewater.

Once we’ve worked out your clean water and wastewater charges, we’ll add fixed charges. These fixed charges cover some of our essential running costs, like maintaining pipes and handling enquiries.

For the 2021-22 charging year, which started on 1 April 2021, everyone who has a water meter will pay £20.34 a year for water fixed charges and £65.18 a year for wastewater charges.

If you qualify for a surface water drainage rebate, your wastewater fixed charge is reduced to £38.52.

Do I need to read my meter?

Yes, you do. Sending us a meter reading means you’ll have a bill that’s only charging you for the water you use. We recommend taking your own readings a few times a year, to keep your bills accurate.

Your bill will show how much water you used between the two most recent meter readings, or between a reading and an estimate. Sometimes, we’ll calculate the bill using two estimates if we don’t have a reading.

In some places, you might have a ‘smart’ meter that regularly sends us up-to-date electronic readings. These are more common in London, for now.

Understanding estimated bills

Bills based on estimated reads are very common and nothing to worry about, as we only take meter readings once a year. If we send you an estimated bill, we base it on the average amount of water you typically use. If we have no previous meter readings, we'll estimate how much you're using based on the average of homes with a similar number of people.

When we next receive a reading, we'll adjust your bill up or down so we only charge you for the amount of water you've used.

You can submit your own meter reading at any time in your online account if your meter is accessible and it’s safe to do so. We'll then review it and send you a new bill if needed.

Is your bill higher than expected?

Your meter records the exact amount of water you use, so it’s the most accurate way for us to calculate your bill. Many customers find they use less water and save money having a meter.

The dates your bill covers

Does your current bill cover a greater time period than your last bill? We try to send metered bills every six months, but this can sometimes take longer, which results in slightly higher bills.

Estimated water use

If we haven’t read your meter and don’t receive a reading from you, we’ll estimate your water use. Your bill will say if this is the case.

If we previously billed you based on your estimated use but now have an accurate meter reading, your bill might rise or fall. This may be the case if your meter reading shows that you’re using more or less water than we estimated. Submit an accurate reading as soon as possible and we can send you a new bill.

How much water you use

If there are now more people at home, working for example, you may be using more water. It’s common to use more water during warm weather. You may also use more water when renovating or when using some appliances more often, like showers and washing machines.

There are some simple steps you can take to reduce your water use:

  1. Fix leaky loos and dripping taps – A leaky loo can waste an average of around 400 litres of water a day
  2. Turn off the tap when washing up or brushing your teeth – a running tap can use six litres of water a minute
  3. Take shorter showers – a shower uses 10 litres of water a minute on average

Leaks in your home

Make sure you don’t have a dripping tap, leaky loo or other hidden leak that’s increasing your water use. Check our advice pages for tips on hunting down leaks.
