Water bills UK 2026 figures show the average household water and sewerage bill in England and Wales rose to £639 a year from April, up £33 or 5.4%, according to industry body Water UK. That’s a smaller jump than 2025’s 26% rise, but bills are still on course to climb 36% overall between 2024-25 and 2029-30 under the regulator’s current price review. Here’s what’s driving the increase, how much your own supplier is charging, and what a water meter actually changes.

Water Bills UK 2026: How Much Has Your Supplier Raised Prices?
Water and wastewater bills for 2026-27 range from £535 at Northumbrian Water to £759 at Southern Water, with the national average sitting at £639. The UK publishes every company’s figures, and the change takes effect from 1 April 2026, though your bill depends on your local tariff, property, and whether you’re on a meter.
| Company | 2026-27 average bill | Change | % change |
|---|---|---|---|
| Southern Water | £759 | +£55 | +8% |
| South West Water | £740 | +£39 | +6% |
| Wessex Water | £695 | +£17 | +3% |
| Dŵr Cymru (Welsh Water) | £683 | +£31 | +5% |
| Anglian Water | £674 | +£44 | +7% |
| United Utilities | £660 | +£57 | +9% |
| Thames Water | £658 | +£3 | +0.4% |
| Yorkshire Water | £636 | +£34 | +6% |
| Hafren Dyfrdwy | £635 | +£54 | +9% |
| Severn Trent Water | £587 | +£52 | +10% |
| Northumbrian Water | £535 | +£31 | +6% |
| National average | £639 | +£33 | +5.4% |
Figures cover combined water and wastewater companies, per Water UK. Water-only companies bill separately and charge less — Affinity Water’s central region, for example, rose from £31 to £266 for 2026-27.
United Utilities and Southern Water saw the biggest cash increases. At the same time, Thames Water, Britain’s largest supplier, added just £3 — not because it’s cheap to run, but because its prices remain among the lowest after historic underpricing, with rises phased differently under Ofwat’s Turnaround Oversight Regime for financially distressed companies.

Why Are Water Bills Rising So Much in 2026?
Bills are rising because Ofwat’s current five-year price review, known as PR24, allowed companies to raise charges by 36% overall between 2024-25 and 2029-30 to fund a £104 billion investment programme — the largest in the sector’s history, covering leak repair, new reservoirs, and cuts to sewage spills.
Roughly 20% of that five-year total was front-loaded into the April 2025 bill, which is why last year’s rise (26%, or £123) was so much steeper than this year’s 5.4%. Ofwat’s interim chief executive, Chris Walters, said the money is funding more than 8 million new water meters, almost 3,000km of replaced pipes, and a 30% cut in storm-overflow sewage spills from 2024 levels, all targeted for April 2027.
There’s a newer piece to this story that most earlier 2026 coverage misses: five companies — Anglian Water, Northumbrian Water, South East Water, Southern Water, and Wessex Water — disputed Ofwat’s December 2024 settlement and referred it to the Competition and Markets Authority. The CMA’s final decision, published on 26 March 2026, awarded them £463 million in combined remedies, about 17% of the £2.7 billion requested, leaving the sector’s overall £104 billion investment total unchanged. Their customers saw only a modest additional uplift, not the much larger rises originally sought.
Water companies also point to rising energy and chemical costs for treating and pumping water, and to long-term underinvestment before the current review, as background pressures. Persistent dry weather is adding to the case for spending on resilience — our guide to UK Drought Explained: The Four Stages and What Happens Next covers how reservoir and river levels feed into that.
What Do Water Meters Change?
A water meter switches your bill from a fixed, property-based charge to one based on the water you actually use. For smaller households, it usually cuts the bill; for larger households using more water than the area average, it can push the bill up instead.
Around 65% of UK homes already have a meter, according to CCW’s most recent Water Mark report, and installation is free. No water company is legally required to introduce compulsory metering — the House of Commons Library confirms that the legislation only gives companies the power to choose it — but some have used that power in areas officially classed as seriously water-stressed. Thames Water, Southern Water, and Anglian Water are installing compulsory smart meters across their regions, and CCW confirms customers there cannot refuse installation. However, most companies allow a switch back to an unmetered tariff within the first year or two if it is more expensive.
Smart meters go further than a standard meter: readings are sent automatically, and they can flag a leak within hours rather than waiting for an unusually high bill. CCW research suggests smart data helps households cut consumption by around 10-15%, on top of any savings from switching to a metered tariff.
If you’re not sure whether switching would help, your water company’s own calculator is the most reliable starting point — CCW notes that households with fewer people than bedrooms typically benefit most, since the fixed unmetered charge is based on property size rather than occupancy.
Rising demand during hot, dry spells is part of why companies want more meters installed — for the temperature side of that story, see UK Heatwave 2026: Met Office Records and Safety Tips.
Help If You’re Struggling to Pay Your Water Bill
If your bill is unaffordable, your water company’s social tariff or the WaterSure scheme can reduce it, and support has expanded substantially this year. Every supplier now runs some form of income-based discount, and over 2 million households are already receiving one, according to Ofwat.
WaterSure specifically caps the bill for metered customers on qualifying benefits who use more water than average because of a large family or a medical condition — Citizens Advice explains it stops the bill exceeding the area’s average metered charge. Most social tariffs, separately, reduce bills for low-income households regardless of family size; South East Water, for instance, offers a 50% discount for households with an income below £17,000 and 30% up to £22,020 from April 2026, which is broadly representative of other suppliers’ tiered discounts. Companies also offer payment breaks and flexible plans for temporary difficulty, and CCW’s free Better Off Calculator checks eligibility across these schemes.
FAQ: Water Bills UK 2026
How much will my water bill go up in 2026?
The national average rise for 2026-27 is £33 (5.4%), taking the typical combined water and sewerage bill to £639, according to Water UK. Your own increase depends on your supplier — anywhere from under £5 at Thames Water to £57 at United Utilities — and on whether you’re metered.
Why are UK water bills rising so much?
Ofwat’s PR24 price review allowed a 36% rise between 2024-25 and 2029-30 to fund £104 billion of investment in leaks, sewage overflows, and supply resilience, with roughly 20% of that already applied in April 2025.
Will getting a water meter save me money?
It depends on your household size relative to your home. Smaller households, or those using less water than the local average, typically save money on their water bills; larger households can end up paying more. Most companies let you trial a meter and switch back within the first year or two if it doesn’t work out.
Can I refuse a water meter?
Not always. In areas officially classed as seriously water-stressed, companies including Thames Water, Southern Water, and Anglian Water can install meters without customer consent, according to the Consumer Council for Water. Elsewhere, metering generally remains optional.
What help is available if I can’t afford my water bill?
Every water company runs a social tariff, and metered customers with high essential water use may also qualify for WaterSure, which caps the bill. Contact your supplier directly or use CCW’s Better Off Calculator to check what you’re entitled to.
Water bills UK 2026 are rising more slowly than last year’s record jump, but the underlying five-year increase is real, and how it lands on your household now depends heavily on whether — and how — you’re metered.
