For 2026/27, the national average household water and wastewater bill in England and Wales is forecast at £639 a year, about £53.25 a month. Actual bills vary by company, meter status, usage and support tariff, so the average is a benchmark, not a target.

The 2026/27 England and Wales average is £639

Water UK forecasts a national average household water and wastewater bill of £639 for 2026/27. That is an annual figure, and the simple monthly equivalent is £53.25. The average is useful as a sense-check, but it does not tell you what a particular household should pay because water charges vary by region and household circumstances.

Ofwat is the regulator for water and wastewater services in England and Wales. It said in January 2026 that the sector's average bill increase for 2026/27 was 5.4%, or £33, compared with the previous year. The national number therefore should be read as a benchmark for the year, not a universal tariff.

Regional differences are large

Water UK's 2026/27 figures show substantial differences between companies. For water-and-wastewater companies, the listed averages range from £535 for Northumbrian Water to £759 for Southern Water. Thames Water's listed average is £658 and United Utilities is £660. Water-only companies have much lower averages because wastewater is provided separately.

This means that a household paying more than £639 is not automatically overcharged. Location is a major part of the tariff. Your bill may also include a different mix of measured and unmeasured charges, support discounts and wastewater costs.

Metered and unmetered households can differ

On a meter, charges are linked to the amount of water you use under the company's charging structure. Without a meter, the charge may be based on a fixed or assessed method instead. A household that uses relatively little water can therefore have a different experience from a larger household with heavy usage.

If your bill has risen sharply, check whether a meter reading or charge basis has changed. A one-off estimate can also make the next bill look unusual if the account is later corrected with an actual reading.

Why a water Direct Debit can look different from the annual average

Water companies often spread payments over the year. Your monthly Direct Debit may therefore be designed to cover expected annual charges rather than match that month's actual water use. Some customers may pay over a different number of instalments or have a balance carried from the previous year.

That is why comparing one month's Direct Debit with £53.25 is not a reliable test on its own. Compare the total annual bill with the company's 2026/27 charge basis and your actual account balance.

Is a 27.5% increase automatically unreasonable?

Not necessarily. Water bills can change because regulated charges have changed, discounts have ended, a meter has been installed, your charging basis has changed or a previous underpayment has been corrected. A percentage change can also look dramatic when the starting bill was unusually low.

The right comparison is the annual cost for the same period and charging basis. If a bill has jumped without a clear explanation, ask the water company for a breakdown and check your meter and account history.

What help is available?

Water UK says around 2.5 million households are expected to receive water-bill support in 2026/27, with an average discount of around 40%, although the exact scheme varies by company. Customers who are struggling should ask their supplier about social tariffs, WaterSure or other payment support where applicable.

If you are in debt with your water company, deal with it early. Citizens Advice can help you understand your options and the company should explain the support available in your area.

Do not use £639 outside England and Wales without checking

The £639 figure is for England and Wales water and wastewater services. Water arrangements differ elsewhere in the UK, so a Scotland, Northern Ireland or other location should be checked against the relevant local charging system rather than using the English and Welsh average as if it were a UK-wide tariff.

The best way to check your own bill

Find your water and wastewater company.
Check whether your home is metered.
Compare the bill with the company's 2026/27 published charges.
Check your actual meter readings and account balance.
Ask about social tariffs or WaterSure if you may qualify.

A household can be above the national average for perfectly legitimate reasons. What matters is whether the bill matches the company's published charging basis and your actual usage.

2026/27 annual water bill benchmark

Worked example

Illustrative example: suppose a household compares its annual bill with the 2026/27 England and Wales national average.

National average: £639 a year.
Monthly equivalent: £639 ÷ 12 = £53.25.
If an illustrative household pays £58 a month, its annual cost would be £58 × 12 = £696.
The difference from the national average would be £696 − £639 = £57 a year.

That does not show the household is being overcharged. The company, region, meter status and support discounts still have to be checked. The £58 figure is illustrative.

The average is therefore a comparison point, not a bill that every household should match. Regional charging rules remain decisive.

It is the annual company charge, rather than the monthly payment alone, that should be compared.

What is the average water bill in the UK?#

For 2026/27, Water UK forecasts a national average household water and wastewater bill of £639 for England and Wales. That is about £53.25 a month when divided evenly across the year. Bills elsewhere in the UK use different charging arrangements, so check your local provider.

Why is my water bill higher than the average?#

The national average is not a standard tariff. Your region, metering, household use, wastewater charges and any discounts can all change the bill. Compare your annual charge with your company’s published 2026/27 rates before assuming a higher-than-average bill is wrong.

Is £60 a month for water expensive?#

Not necessarily. At £60 a month, the annual amount would be £720, which is above the England and Wales 2026/27 national average but still within the range of regional household charges. Your company and charging method matter more than the monthly number alone.

Do water bills go up every year?#

They can, but the amount of change varies by company and year. Water UK forecasts the 2026/27 national average in England and Wales at £639, up £33 or 5.4%. A particular household can see a different change because regional charges and personal circumstances vary.

Why did my water bill rise by 27.5%?#

A large percentage increase can have several causes, including annual price changes, a meter change, a corrected estimate or a loss of a discount. Compare the annual bill, charging basis and meter readings for the same period. Your water company should explain any unexplained jump.

Can I get help with a high water bill?#

Yes. Water companies have support schemes such as social tariffs, and Water UK says around 2.5 million households are expected to receive support in 2026/27. Ask your company what you qualify for. Citizens Advice can also help if you are struggling with the bill.

Is the £639 water bill figure for the whole UK?#

No. The £639 figure is Water UK’s 2026/27 national average for England and Wales water and wastewater bills. Scotland and Northern Ireland have different arrangements, so use the relevant local charging information rather than treating £639 as a UK-wide tariff.
