In England and Wales, the average household water and sewerage bill is forecast at £639 for 2026/27, a £33 or 5.4% rise from April 2026 according to Water UK and Discover Water. Your own bill depends on your water company, whether you have a meter, your usage and local charges.

The average water bill UK households face in 2026/27 is rising again from April 2026. The England and Wales average is forecast at £639 a year for combined water and sewerage, but household bills vary sharply by region, water company, meter status and usage.
That means the useful question is not just “how much are water bills going up?” but “what will my own bill do, and what help or savings can I use?” This guide uses Water UK, Discover Water and Ofwat sources where possible, then shows practical steps if you cannot afford the increase.

Why Your Water Bill Is Rising in 2026
Ofwat, the water industry regulator, approved a five-year investment programme for 2025 to 2030. Ofwat says the settlement supports £104 billion of investment to improve drinking-water supplies, reduce leakage, upgrade infrastructure and cut pollution.
The main drivers behind the 2026/27 water bill increase include:
- Infrastructure investment: companies are preparing to invest around £20 billion in 2026/27 as part of the wider five-year programme
- Leakage and resilience work: replacing pipes, improving treatment works and preparing for drought or flood pressure
- Environmental obligations: reducing sewage spills and improving river and coastal water quality
- Inflation and financing costs: company charges also reflect inflation adjustments and the cost of funding long-term upgrades
Water bills are only one part of the wider household squeeze. See our April 2026 bill increases guide and energy price cap update for the broader budget picture.
The Regulatory Background
Ofwat sets price controls every five years through its Periodic Review process. The current review (PR24) covers 2025-2030 and allows higher increases than previous periods.
Consumer groups criticised these approvals. They argue water companies should absorb more costs from their profits rather than charging households already facing financial pressure.
Average Water Bills by Region and Provider
Average bills vary significantly across England and Wales. Discover Water shows an average combined household water and sewerage bill of £639 for 2026/27, but your actual bill can be higher or lower depending on where you live and how you are charged.
| Water and sewerage company | Forecast 2026/27 average bill | Approx. annual change |
|---|---|---|
| Anglian Water | £674 | +£44 |
| Dwr Cymru Welsh Water | £683 | +£31 |
| Hafren Dyfrdwy | £635 | +£54 |
| Northumbrian Water | £535 | +£31 |
| Severn Trent Water | £587 | +£52 |
| South West Water | £740 | +£39 |
| Southern Water | £759 | +£55 |
| Thames Water | £658 | +£3 |
| United Utilities | £660 | +£57 |
| Wessex Water | £695 | +£17 |
| Yorkshire Water | £636 | +£34 |
These figures are averages, not a promise about your own bill. Metered households pay based on use, while unmetered households are usually charged using rateable value or assessed charges. Check your provider’s 2026/27 charges scheme for your exact rates.
How to Calculate Your Bill Increase
Working out your exact increase depends on your current bill and payment method. Most households receive annual bills, but some pay monthly or quarterly.
Find your current annual water bill amount. You can locate this on your latest statement or log into your provider’s online account portal.
Multiply this figure by your company’s percentage increase rate. For example, if you currently pay £400 annually and face a 10% rise, your new bill will be £440.
Metered vs Unmetered Bills
Customers with water meters pay for actual usage, whilst unmetered households pay fixed charges based on property rateable values. Both groups face similar percentage increases, but the absolute amounts differ.
Metered customers can control costs by reducing consumption. Unmetered households have less flexibility but may benefit from switching to metered charging if they use relatively little water.
5 Ways to Cut Your Water Bill Right Now
Despite these increases, you can take immediate action to reduce your water costs. These strategies work whether you have a meter or pay fixed charges.
1. Fix Leaks and Dripping Taps
A dripping tap wastes 15 litres daily, costing metered customers around £25 yearly. Check all taps, toilet cisterns, and visible pipes for leaks. Most repairs cost under £50 but save much more over time.
2. Install Water-Saving Devices
Water companies often provide free water-saving kits including:
- Shower timers and low-flow shower heads
- Toilet cistern displacement devices
- Tap aerators to reduce flow rates
- Garden water butts for collecting rainwater
These devices can reduce household water use by 15-20% without affecting comfort.
3. Change Your Washing Habits
Run washing machines and dishwashers only with full loads. Use eco-settings where available. Take shorter showers rather than baths – a typical bath uses 80 litres compared to 35 litres for a 5-minute shower.
4. Apply for Social Tariffs
Water companies must offer reduced-rate tariffs for customers struggling financially. Eligibility varies but typically includes households receiving benefits or with low incomes.
WaterSure caps bills for metered customers with three or more children or certain medical conditions. This prevents bills exceeding the average unmetered charge in your area.
5. Consider Switching to a Meter
Unlike energy, you cannot switch water suppliers. However, you can usually switch from unmetered to metered billing if this saves money.
Most water companies estimate potential savings online. Generally, smaller households benefit from metered charging whilst larger families pay less on unmetered rates.
Getting Help If You Can’t Afford Your Bill
Water debt affects over 3 million UK households. If you struggle with these water bill increase 2026 costs, help is available.
Contact your water company immediately if you cannot pay. All providers offer payment plans, temporary payment holidays, and debt write-off schemes for qualifying customers.
Priority Services
Register for Priority Services if you or someone in your household:
- Has a disability or chronic illness
- Is over 60 years old
- Has young children
- Faces language barriers
Priority customers receive advance notice of supply interruptions, free bottled water during outages, and extra support with billing queries.
Independent Help
Citizens Advice provides free debt advice and can negotiate with water companies on your behalf. The Consumer Council for Water handles complaints and disputes.
StepChange Debt Charity offers practical guidance on managing water debt alongside other household bills. Their services remain completely free and confidential.

Many people believe switching water suppliers could save money, but household water customers generally cannot switch supplier in the same way as energy customers. A water meter can reduce bills for some smaller or lower-use households, but it can increase costs for larger households or high water users. Check your water company guidance before switching.
Should You Switch to a Water Meter?
Switching to metered billing offers the best opportunity to control rising water costs. However, this decision needs careful consideration based on your household circumstances.
Meters benefit households that use less water than average. Single people, couples without children, and families who prioritise water conservation typically save money.
Larger families or households with high water usage often pay more on metered charges. Properties with swimming pools, large gardens requiring regular watering, or medical needs requiring extra water usage should carefully calculate potential costs.
The Switch Process
Most water companies install meters free of charge within 90 days of your request. You cannot usually return to unmetered billing after switching, though some companies allow changes within the first 12-24 months.
Your new charges begin once the meter starts recording usage. Bills typically arrive quarterly and show both water supply and sewerage charges based on consumption.
Example: How a Smaller Household Could Cut a Metered Bill
A single-person household on an unmetered charge may be paying more than its actual water use justifies. If that household uses a company calculator and finds a meter would be cheaper, requesting a meter can make the bill more controllable because lower usage then feeds through into lower charges.
The saving is not guaranteed. Larger households, homes with high medical water needs or properties with heavy garden use may pay more on a meter. Before switching, use your water company’s calculator and ask whether any trial or reversal period applies in your area.
Step-by-Step Guide to Cutting Your Water Bill
Follow these specific steps to reduce your water costs despite 2026 price increases:
- Find your current bill: Log into your water company’s website or check your latest paper statement to identify your annual cost
- Calculate your increase: Multiply your current bill by your provider’s 2026 percentage increase to determine additional costs
- Request a meter quote: Use your company’s online calculator to estimate metered charges based on household size and typical usage
- Audit your water use: Check all taps, toilets, and appliances for leaks or inefficient operation
- Order free water-saving devices: Contact your water company to request shower timers, tap aerators, and cistern devices
- Apply for available support: Check eligibility for social tariffs, WaterSure capping, or Priority Services registration
- Install efficiency measures: Fit water-saving devices and repair any leaks found during your audit
- Monitor your usage: Track consumption for 3-6 months to identify additional saving opportunities
What to Do Next
Take these immediate actions to minimise the impact of 2026 water bill increases:
Contact your water company this week to request a free meter assessment if you live in a smaller household. Most providers complete installations within 90 days.
Order water-saving devices from your provider’s website or customer service line. These typically arrive within 2-3 weeks and installation takes under an hour.
Check your eligibility for social tariffs or WaterSure by reviewing the criteria on your company’s website or calling their customer service team directly.
Audit your property for leaks and inefficient fixtures. Focus on dripping taps, running toilets, and old shower heads which waste significant amounts.
