Why is my bill going up?

We know that any increase in costs can be difficult, especially right now, and we haven’t taken the decision lightly.

Our regulator Ofwat decides the level of investment we can make in our network, and the total amount we can charge our customers over a five year period, so prices are fair for customers.

We're investing £2.1 billion over the next five years to improve how we deliver drinking water and to make sure you can rely on a safe, secure water supply today and for years to come. No dividends have been paid to our ultimate shareholders since 2019 and there are no plans to pay any in the next financial year.

How much is my bill going up?

From 1 April, the average yearly household bill for drinking water will be £324.

This works out at around 89p a day for all the water you use at home - for drinking, cooking, cleaning, gardening and everything else you need it for. This is a seven per cent increase, or 6p a day, on last year’s average bill.

This includes all customers, and covers a range of tariffs - metered, unmetered and rateable value.

The increase you see on your bill may be different from the average bill and it also includes waste water charges. The waste water companies have their own price changes.

What about waste water charges?

The waste water companies have their own price changes.

Generally it costs more to remove and treat the dirty water than it does to supply fresh water, so waste water charges tend to be higher. We bill our customers for waste water services on behalf of Southern Water, Thames Water, Severn Trent Connect and Last Mile Water. We do this to make things simpler for our shared customers.

FAQs

We have some FAQs here, that might help answer any further questions you might have about the price rise.

Average bill changes

How we bill you

Metered bills:

If your property has a water meter, we'll bill you every six months based on how much water you've used. This is measured in cubic metres (m3) by your meter. Your bill will also include a standing charge.

Unmetered bills:

If your property doesn't have a meter, you'll receive one bill a year. This covers the period from 1 April to 31 March the following year.

These charges cover the cost of taking water from the environment, treating it, and supplying top-quality drinking water to your taps.

Support On Tap

Talking about money can be tough. If you're struggling to pay your bill, we have a range of schemes to help.

Social tariff

From 1 April 2026, we're changing our Social Tariff structure to help even more customers who need support paying their bills.

What's changing?

We already apply a tiered discount based on your household income (not including any disability or housing payments you receive). We’re increasing the amount your household income can be, to be eligible for a discount.

  • If your total household income is between £17,000 and £22,020, you'll receive a 30 per cent discount on your water bill.
  • If your household income is less than £17,000, you'll receive a 50 per cent discount.

As we also bill you for waste water, the tariff will include a discount on that part of your bill too.

You can find out more about our Social Tariff and other schemes here.

Other ways we can help

We've also expanded our data sharing scheme with local councils. This helps us automatically identify and sign up eligible customers who might benefit from extra financial help.

Our Trusted Partners Scheme works with charities and voluntary groups to automatically transfer customers onto the tariff and Priority Services Register without needing to apply.

If you haven't heard from us about this and need some extra help, please get in touch. We're here to help.

What is a cubic metre (m3)?

Graphic of 1 cubic metre = 10 washing machine cycles.
One cubic metre might not sound like much, but it's the same as 1,000 litres – that's like ten washing machine cycles.

It's a unit of volume that measures one metre wide, one metre high, and one metre deep.

Our supply area

We supply top quality drinking water to 2.3 million people across the south east of England. From Aldershot in Hampshire across to Whitstable in Kent, our teams work hard to keep taps flowing across Hampshire, Berkshire, Surrey, Sussex and Kent.

Help paying your bill

If you're struggling to pay your bill, please don't worry. We're here to help.

We have a range of support tariffs and can confidentially discuss an affordable payment plan. The best thing to do is give us a call so we can find the right option for you.

Waste water charges

We only supply clean drinking water. We don't deal with waste water or sewage.

We do bill you on behalf of Southern Water and Thames Water to make things simpler, but we are a separate company.

This means we can't help with waste water emergencies, as this isn't part of our network.

If you're not sure which area you're in you can use the handy postcode tool on the Water UK website(opens in a new tab)
