Bills
TL;DR
If you are struggling to pay your water bill, your water company is legally required to offer you a payment arrangement. WaterSure caps bills for metered customers who use a lot of water for medical reasons or have three or more children under 19. Social tariffs reduce bills for low-income households. Water debt cannot lead to disconnection for residential customers in England and Wales; water companies must pursue other debt recovery routes first.
Water bills in England and Wales are set by private water companies within limits approved by Ofwat, the water sector economic regulator. In Scotland, Scottish Water is a publicly owned company with charges set by the Water Industry Commission for Scotland. Water bill debt affects approximately 2 million UK households according to Citizens Advice data from 2025, making water one of the most common household bill arrears categories alongside energy and council tax.
Unlike energy suppliers, water companies cannot disconnect residential customers in England and Wales for non-payment - a longstanding protection that distinguishes water from other utilities. However, they can pursue unpaid bills through the courts and apply charges. Understanding the available assistance schemes before falling into arrears is the most effective approach. This guide covers WaterSure, social tariffs, affordability schemes and debt options specific to water bills.
Key facts (2026)
- Water companies in England and Wales cannot disconnect residential customers for non-payment of bills; this prohibition is set out in the Water Industry Act 1991, Section 61 (amended).
- WaterSure caps bills for eligible metered households at the average metered bill in their region, regardless of actual consumption (Ofwat, WaterSure scheme conditions 2025).
- All water companies in England and Wales must offer a social tariff for low-income customers, though eligibility criteria and discount levels vary by company (Ofwat, 2014 social tariff guidance, reviewed 2025).
- Average household water bills in England and Wales for 2025/26 are approximately £473 per year, rising by approximately 36 percent from April 2025 under Ofwat's PR24 price review (Ofwat, 2025).
- The average water and sewerage bill for 2025/26 includes network investment costs approved under Ofwat's five-year price review published in December 2024 (Ofwat PR24 Final Determination).
WaterSure: the bill cap for high-usage metered households
WaterSure is a cross-subsidy scheme that caps the metered water bill for eligible households at the average metered bill in their region. To qualify, you must be a metered customer and meet at least one of two conditions: you must have three or more dependent children under 19 living at the property, or a household member must have a medical condition requiring high water use (such as Crohn's disease, incontinence, a renal condition requiring home dialysis, or severe skin conditions requiring regular bathing). You must also be receiving at least one qualifying means-tested benefit, or your water bills must represent a significant proportion of your household income. Apply through your water company; evidence of medical conditions and benefit receipt is typically required.
Social tariffs: low-income bill discounts
All water and sewerage companies in England and Wales are required by Ofwat to offer a social tariff. The design - including eligibility thresholds, discount levels and qualifying criteria - is set by each company individually within Ofwat's framework. Discounts range from 20 percent to over 50 percent of the standard bill, and eligibility is typically based on receipt of means-tested benefits (Universal Credit, Pension Credit, Housing Benefit), low household income, or high water-to-income ratios. Scottish Water offers separate assistance through the Low Income Water Discount Scheme (LIWDS), which provides equivalent support for eligible households in Scotland. Check your water company's website for its specific social tariff name and application process.
Payment arrangements and debt support
If you cannot pay your water bill, contact your water company before the debt grows. Water companies are legally required to offer reasonable payment arrangements - typically spreading the arrears over a period of months or years alongside ongoing charges. Some companies offer debt write-off or matching schemes, where the company matches pound-for-pound any payments you make against existing arrears. Citizens Advice Water can help you negotiate with your water company if direct discussions are not productive. Free debt advice is available from StepChange, National Debtline and Citizens Advice - all at no cost to you.
Water metering: switching from a rateable value bill
Households on unmetered bills pay based on the rateable value (RV) of their property - a historic assessment with no direct relationship to modern water use. Switching to a meter is free and must be offered by all water companies to any customer who requests it. Metering is generally financially beneficial for households with fewer occupants than bedrooms, as water use is typically lower than the RV bill assumes. Ofwat data suggests that metered households use approximately 10 to 15 percent less water on average than unmetered equivalents. You have a 24-month trial period after installation: if metering costs you more, you can revert to your previous RV-based charge.
The 2025 bill increase and the Ofwat PR24 price review
Ofwat's PR24 Final Determination, published in December 2024, approved significant investment by water companies in network infrastructure, sewage overflow reduction and drought resilience. This was funded through an average 36 percent increase in bills from April 2025, the largest single-year increase since water privatisation. The Ofwat review also introduced new performance commitments with financial penalties for companies that miss targets on leakage, service quality and environmental outcomes. Ofwat publishes a comparative table of company performance against these metrics annually.

Frequently asked questions
Can my water be cut off if I don't pay my bill?
No. Water companies in England and Wales cannot disconnect residential properties for non-payment of bills. This prohibition is set out in the Water Industry Act 1991. However, they can pursue the debt through the courts, apply for a County Court Judgment and instruct enforcement agents to collect, so ignoring water debt is not without serious consequences.
How do I apply for WaterSure?
Contact your water company directly and ask to apply for WaterSure. You will need to provide evidence that you meet the eligibility conditions (three or more dependent children, or a qualifying medical condition) and that you receive at least one means-tested benefit. Your water company may ask your GP or a healthcare professional to confirm a medical condition.
How much could a social tariff save me?
Discounts range from 20 percent to over 50 percent of the standard bill depending on your water company and the specific scheme. On an average bill of approximately £473 per year (2025/26), a 30 percent discount would save approximately £142 per year. Check your water company's own scheme for the applicable discount level and eligibility threshold.
What if my water company rejects my payment arrangement request?
Ofwat requires water companies to be flexible with customers in genuine financial difficulty. If your company refuses a reasonable arrangement, escalate to the Consumer Council for Water (CCW), which is the independent consumer body for water customers in England and Wales and can intervene in disputes. CCW's helpline is free.
Is water bill help available in Scotland?
Yes. Scottish Water's Low Income Water Discount Scheme (LIWDS) provides bill reductions for eligible low-income households in Scotland. Eligibility is means-tested and the scheme is administered through local councils. Contact your local council or the Scottish Government's advice services for details of the current scheme conditions.
