What’s Included in the Average Water Bill?

A lot of factors go into determining your water and sewerage bill. Water companies have to maintain the public infrastructure and provide the treatment for both the clean water and the wastewater.

Here we've broken down what’s included in the average water bill, as well as in the average sewerage bill, in the table below.

Water bill (£16) Sewerage bill (£18)
Maintaining the network of reservoirs, treatment works, pumping stations, and pipes Building and maintaining sewer pipes
Gathering and collecting the water from rivers and reservoirs or pumping it from underground rocks Pumping sewage to treatment works, various stages, and methods of treatment
Storing the water ready to be treated Flowing cleaned and treated wastewater back into rivers, and the sea
Treating, cleaning, and distributing water to properties Converting solid material from sewage into gas for energy

This means that over a year on your average water bill you will spend £200 for water usage and £219 on sewerage.

What Is the Average Water Usage?

How can one know how much water their homes use? Not many people have any way of calculating their average water usage, even with a water meter in their homes.

Therefore, to understand the average UK water bill in the UK, we need to understand the average water usage. To give you an indication, we look at the average water usage in litres per day* according to the number of people living at home:

Lowering Your Average Water Usage

Looking at some of these numbers and charts, one may feel inclined to change their habits to reduce their average water usage and save on their monthly water bill.

Here are some quick affordable tips on what you can do to lower your water usage and, consequently, your monthly water bill (if you have a metered water rate).

  • Flow regulators - These can be inserted on taps, garden hoses, and showerheads. Flow regulators reduce the amount of water coming out of the tap and therefore reduce your water usage.

  • Blocks for toilets - If you don't want to pay for a new low flush toilet. Simply placing blocks or bricks in the cistern will significantly reduce the amount of water used on every flush. The extra space occupied by the bricks simply replaces the space occupied by water. The more bricks placed, the more water you save.

  • Shower time - As seen above, a 10-minute shower equals the usage of a full bath. Turning off the water during your shower as you soap and wash will notably reduce that water usage.

  • Full loads - Wait until you have a full load of laundry or dishes to wash before using those appliances so you can maximise your water usage.

  • Repair leaks - These can account for up to 112 litres of water lost daily. Call your plumber and maintain your plumbing to ensure there are no leaky pipes.

Many of these water-saving items can be obtained for free via your water supplier, Northumbrian Water Living to name one, and other water-saving organizations.

Did you know? On average, a person with a metered water rate in the UK uses 31.7% less water* than unmetered individuals.

What If You Can’t Pay Your Monthly Water Bill?


Times are tough. More and more people are struggling to make ends meet. If this is your case, don't fret – you have many options at your disposal to help you pay your monthly water bill.

  • Using your benefits - You can pay some bills directly from your benefits (Universal Credit, Pension Credit, Income support, and income-related benefits). This helps avoid falling into debt and having to pay large interest amounts (getting into further debt!).

  • Customer assistance funds - Many suppliers offer assistance to those struggling with their bills. With Welsh Water, for example, successful candidates can receive 50% off their arrears after a successful 6-month payment plan.

  • Payment holiday - This Yorkshire Water initiative puts a hold on collecting payment on their monthly water bill for a while. Helpful for those who lost employment, those who are unable to make a payment or need to reduce payments.

  • WaterSure Scheme - This scheme is for people on benefits that have a high water consumption due to medical reasons OR those with multiple school-aged children. Available through all suppliers in the UK, this scheme puts a cap on your average monthly water bill.

Stay Calm! No water supplier can cut your water if you haven't paid your water bill. This doesn't mean you shouldn't bother paying your water bill! Contact your supplier, set up a debt payment plan, and avoid further stress that can arise from debt collecting agencies or being taken to court.

Does Water Hardness Affect My Average Water Bill?

Water hardness depends on the concentration of minerals, such as magnesium and calcium, present in your water. This occurs due to the type of rocks that the rainwater falls on and passes through. Typically, those households in the south and west of England have hard to very hard water, whereas in Wales and Scotland the water is softer.

Although water hardness does not generally affect your water bill since it is based on the rock type rather than the supplier, there are some factors that might indirectly affect your monthly water bill.
