Understand your bill

Whatever your tariff and however you pay, the amount you owe usually varies from bill to bill. But your payments will increase if you have an outstanding balance on your account.

This can happen if you didn’t pay your last bill, or paid smaller amounts than you should. It can also happen if you missed or delayed some payments and didn’t make up for them.

We’ll always need to carry these balances over unless we’ve set up a special payment arrangement with you.

Making the right payments is important so you don’t build up debt. If you’re falling behind, we can help you get back on track.

You may be able to tackle old debt in a manageable way through our payment matching scheme. We may also be able to help by spreading the cost of your bill, or through a financial support scheme.

We understand that sometimes you might forget or are unable to pay when payment is due. We’ll issue a few reminders asking you to pay. If you’re unable to do so, it’s really important that you let us know so we can try to help. We may be able to split your bill into smaller chunks, pause your payments or check if you qualify for discounted tariffs or grants. Learn more.

Unless you tell us you’re having problems, all we’ll know is that your payment is overdue. We’ll need to start debt recovery action, which could affect your credit rating. The sooner we know what’s happening, the sooner we can find a solution for you. Read our debt recovery procedure.

We commit to reducing leaks from our network every year. Because we haven't met our targets in previous years, we included a discount in our 2021/22 charges. This discount will not apply to our 2022/23 charges. Learn more about this and how we work to deliver great value.

You may be eligible for one or more of the following:

• If you’re on a low income, you might qualify for our WaterHelp scheme. This reduces your bill by 50%.
• If you're on a water meter, receive a means-tested benefit, and have a large family or water-dependent medical condition, you could qualify for our WaterSure scheme. This year, it caps your bill at £230 for your water charges and £189 for your wastewater charges.
• If your property isn’t connected to our surface water drains and only uses foul water drainage – for instance, because rainwater from your property drains to a river, stream or soakaway – you may be able to claim back some of your fixed wastewater charges.
• If you can provide evidence that more than 10% of the water you use doesn’t return to our sewers, we may be able to reduce your wastewater bill.
