Behind on Water Bills? Ask About Lower Charges and Arrears Support
Ask your water company to review current charges and old debt. Social tariffs and payment schemes may help, with eligibility varying by supplier.

A water bill that has become hard to manage may contain two separate problems: the cost of current water and sewerage, and repayments on a balance from earlier bills. Asking your supplier to show both amounts can make it easier to find support and judge whether a proposed payment fits your budget.
In England and Wales, help may include a lower charge through a social tariff, a scheme that contributes towards older debt, or both. The options and eligibility rules vary by supplier, so ask about the specific support available for your account.

Start by separating the bill into two amounts
Contact the water company named on your bill and explain if its suggested payment would leave you short for essentials such as food or rent. Ask for the team that handles payment difficulties. It can help to have your account number, latest bill, and a rough picture of your income and spending ready.
Ask the company to distinguish the current year’s water and sewerage charges from any older arrears. If a separate company bills you for sewerage, the Consumer Council for Water (CCW) advises contacting that company as well.
You might say: “My bill includes an overdue balance. Could you tell me how much I owe for this year and how much is older debt? I can afford £___ a month in total. Can you check whether I qualify for a cheaper tariff or help clearing the balance?” Giving a realistic monthly amount helps keep the discussion focused on a plan you can maintain.
Ofwat’s customer service and support report for 2025/26, published on 29 October 2026, counted £2.28 billion in water bill arrears across about 2.7 million active household accounts in England and Wales. There were about 207,000 fewer active accounts behind on payments than the previous year, while the average overdue balance rose from £734 to £845. Fewer accounts were in arrears, but the average debt was £111 higher.
Check whether a social tariff could lower current charges
Every household water company in England and Wales offers a social tariff for customers on low incomes. The CCW supplier list explains each company’s rules, the help it offers and how to apply. Some suppliers assess household income, so being in work doesn’t automatically mean you’re ineligible. You can also read this guide to water bill discounts for more information about possible eligibility.
In 2025/26, 7.7% of household customers received social-tariff support, compared with 5.8% the year before. The £354 figure reported in headlines was the average discount among people receiving support. It isn’t a standard amount that every applicant will get. Ask your supplier what your own annual charge would be and when any reduction would start. That gives you a clearer figure for budgeting and helps establish whether the change applies to an earlier bill.
Households with high water needs may also be able to ask about a bill cap. If your home has a meter, someone in the household receives qualifying benefits, and a large family or medical need means you use more water, you may qualify for support. CCW explains WaterSure in England and how to ask about equivalent support in Wales.
Ask separately about help with older arrears
A standard instalment plan spreads the balance over time. Some suppliers also offer schemes that reduce eligible arrears when customers keep up with agreed payments. These schemes have their own conditions, so signing up for ordinary instalments doesn’t necessarily mean you’re enrolled in debt support.
Under United Utilities’ payment matching scheme, eligible customers pay their ongoing charges and an agreed affordable amount towards arrears from previous years, while the company adds a contribution. If £10 of an agreed payment goes towards old debt, the company initially adds £10, so the balance falls by £20. After 12 months on the scheme, its contribution rises to £2 for each £1 the customer pays towards arrears.
Dŵr Cymru Welsh Water’s Customer Assistance Fund has a different structure. Customers struggling with more than £150 in arrears that are at least six months overdue can apply. If accepted, they need to maintain the agreed payments for six months for half the old arrears to be cleared. Keeping up payments for a further six months clears the remaining half.
If the proposed instalment still feels unaffordable
Tell your supplier what remains after essential spending and ask it to review the payment. If it offers a short break, check when payments will restart and how the paused amount will be added back. Before agreeing, request a written breakdown of current charges, debt repayments and any company contribution. You should be able to see what the next payment will cover.
For domestic water bills in England and Wales, a supplier can’t disconnect household water because of unpaid charges. It can still seek to recover the debt, including through the courts. If you receive court papers, or you’re also behind on rent, council tax or energy bills, StepChange offers free help with water debt. This guide to getting help when several bills are overdue may also help you decide where to start. A free debt adviser can help you work out what remains affordable after essential costs.
Questions people often ask
Do I have to miss a payment before I ask for help?
No. If the next bill looks unaffordable, contact your supplier now. You can ask about a social tariff or different instalments before falling behind. Debt-matching schemes have separate eligibility rules and generally require existing arrears.
Can I claim a £354 discount?
£354 was the average social-tariff discount among recipients in England and Wales in 2025/26. Apply through your own water company; the amount depends on its rules and your circumstances.
Could unpaid household water bills lead to disconnection?
Your supplier can’t disconnect a household supply in England or Wales for unpaid domestic bills. It may still pursue the balance, including through the courts. If you receive court papers, contact a free debt adviser.
The useful first step is to get the current charge and old balance stated separately, then ask which forms of support apply to each. That gives you a clearer basis for agreeing a payment you can keep up with.
