Compared against the England and Wales average. Your own company average is often the fairer test, and it is in the table below.
What you pay here depends on where you live. Put your postcode in and we will show your area's figure rather than the national one.
What you might be owed
Routinely unclaimed. We do not administer any of these and take nothing for pointing at them.
WaterSure
Caps your bill at the company's average household bill. Average saving £325 a year. 260,800 households on it.
You need a meter, a means tested benefit, and either a medical condition requiring extra water or three or more children under 19 in full time education.
Company social tariffs
Discounts from roughly 20% to 99%, set by each company. 1.96 million customers, average reduction £190.
Income based. Thresholds vary by company, typically £17,000 to £30,000 household income. Severn Trent's Big Difference Scheme goes up to £411 off below £24,454.
Leak allowance
Rebates water lost through a leak on your own supply pipe, and can adjust sewerage charges too.
Metered customers. Largely discretionary and the policies differ by company. Typically you must repair within 30 days of finding it.
If you cannot pay
Knowing what a bill should cost is no use if you cannot afford it. None of
this costs anything and none of it goes through us.
Water companies cannot cut you off
It is illegal to disconnect a household for non payment of water. Anyone telling you otherwise is wrong.
Ask about your company's social tariff
Every company has one, they are all different, and reductions run from about £120 to over £400 a year. It is a postcode lottery, but the discount is real.
Ask about WaterSure
Caps your bill at the company average, saving about £325 a year. You need a meter, a means tested benefit, and either a medical need for extra water or three or more children under 19.
Ask for a payment plan or a leak allowance
Companies will spread the bill, and will usually rebate water lost to a leak on your own supply pipe if you fix it promptly.

What you need to know
The things that stop the headline figure being misread.
Households in England and Wales cannot switch water supplier. Supply is a regional monopoly and the 2014 reforms deliberately excluded domestic customers.
Businesses can switch retailer in England, and have been able to since 1 April 2017. In Wales only sites using more than 50 megalitres a year are eligible.
You have a legal right to request a meter, free, under section 144A of the Water Industry Act 1991. You can switch back to unmetered within 12 months, or 24 months with Welsh Water.
As a rough rule, a meter saves money if you have more bedrooms than people.
Where a meter cannot be fitted, the company must offer assessed charges based on the property rather than usage.
Bills are rising because of PR24. Ofwat approved £104bn of investment for 2025 to 2030, taking the average bill from £440 to £597 before inflation, a 36% rise front loaded into the first year.
Five companies challenged that settlement. The Competition and Markets Authority ruled on 10 March 2026, awarding them £463m more, about 17% of what they asked for, worth roughly 2.2% on their customers' bills.
There is no national social tariff. Support is company by company, which the consumer body CCW calls a postcode lottery, with reductions ranging from £120 to £314.
Households in Northern Ireland pay nothing for water. Domestic charges have been deferred since 2007 and are funded through the regional rate instead.
Scotland is different again. There is no separate water bill; charges are collected with council tax and banded, and the average is £532.
WaterSure reform takes effect. Income cap £25,745, eligibility extended to PIP, DLA and Attendance Allowance, automatic enrolment replaces application. About 53,000 more households.

Water only companies, water element 2026/27
These figures are the water element alone. Your sewerage is billed separately by the regional wastewater company on top, so your total bill is higher than the number shown. Two names on older lists have gone: Bournemouth Water transferred its licence to South West Water in 2016 and was dissolved in 2024, and Essex and Suffolk is a trading name of Northumbrian rather than a separate company.
Competition watchdog hands five water companies £463m more
Anglian, Northumbrian, South East, Southern and Wessex disputed Ofwat's price review settlement. The CMA raised their allowed return from 4.03% to 4.20% and awarded £463m of additional revenue, about 17% of what they asked for. Expect roughly 2.2% on those customers' bills across the five year period. The five serve about seven million households.
WaterSure reformed, about 300,000 households to benefit
The income cap rises to £25,745 and eligibility extends to people receiving PIP, DLA or Attendance Allowance, bringing in about 53,000 more households. The medical practitioner's note is dropped for unlisted conditions and automatic enrolment replaces the application. A new single occupier cap is introduced. About 53,000 single households save an extra £100 and about 130,000 multi occupant households save around £26.
The average household bill in England and Wales for 2026/27 is £639, made up of £309 for water and £330 for sewerage, up 5.4%. Southern Water is dearest at £759 and Northumbrian cheapest at £535, a £224 spread for a service nobody can switch away from. Severn Trent took the largest rise among the big companies at 10%; Thames took 0.4%.
White paper confirms no national water social tariff
A New Vision for Water confirms support stays company by company, with an average £640m a year available for low income customers to 2030 and an industry commitment to address water poverty by that date. It also proposes abolishing Ofwat in favour of a single integrated regulator, with no date set. Campaigners at CCW and Independent Age continue to press for one national scheme.
Do not assume a national scheme exists. What you get depends entirely on which company happens to serve your postcode.
Where this comes from, and where it could be wrong
Known limits of this page
Water UK publishes a combined figure per company. The split between water and sewerage by company is not available from a primary source, only the national split of £309 and £330.
Ofwat's own website refused every automated request while this page was built. The Ofwat material here comes from the official press mirror, the CMA and gov.uk rather than from Ofwat directly.
There is no published year by year bill path for 2026/27 to 2029/30. Only the start and end points of the price review are official. Anything showing a year by year trajectory is somebody's projection.
Water company boundaries follow river catchments, not postcodes. Where we match a postcode to a company we say so is approximate, and where an area is split between two companies we show both rather than guess.
Bristol Water applied in 2022 to merge its licence into South West Water and we could not confirm whether that completed. It still bills under its own name.
