Water Bill Too High? Average UK Water Bill 2026 & How to Reduce It

Water bills in England and Wales are set by regional monopoly companies and regulated by Ofwat. Unlike energy, you cannot switch water provider — you are assigned one based on where you live. That makes understanding your bill and reducing your usage all the more important.

This figure represents an increase of around 21% compared to 2024–25, following Ofwat’s price review (PR24) which allowed water companies to raise bills to fund infrastructure investment. Bills vary significantly by region, with some areas paying over £550 and others under £400.

Your bill typically has two components: a water supply charge (clean water delivered to your property) and a sewerage charge (wastewater removal and treatment). In some areas these are handled by two separate companies.

There are two ways you can be billed for water in England and Wales, and the difference can mean hundreds of pounds a year.

Unmetered (rateable value)

If you do not have a water meter, your bill is based on the rateable value (RV) of your property — a valuation originally set in 1990 by the Valuation Office Agency. It has nothing to do with how much water you actually use. A large period property will have a high rateable value and therefore a high water bill, even if only one person lives there.

Metered

With a water meter, you pay for exactly what you use. Your bill is calculated using a standing charge (a fixed daily amount, typically £40–£80 per year) plus a volumetric charge (a rate per cubic metre of water consumed, usually £1.50–£3.00 per m³).

Which is cheaper?

As a general rule, a meter saves you money if the number of people in your home is fewer than the number of bedrooms. So a couple living in a three-bedroom house will almost certainly save with a meter. A family of five in a two-bedroom flat probably will not.

Ofwat estimates that around 60% of households in England and Wales now have a water meter. If you switch to a meter and find your bills are higher, you have the right to switch back to unmetered billing within 24 months (in most water company areas).

Every household in England and Wales has the legal right to request a water meter, and your water company must install one free of charge. Here is how:

1. Contact your water company. Call them, visit their website or fill in an online application form to request a meter.
2. They will survey your property. An engineer will check whether a meter can be fitted at your external stop tap (the point where the mains supply enters your property boundary).
3. Installation takes 1–4 weeks. In most cases the meter is fitted externally and the work takes less than an hour. You do not need to be at home.
4. Your billing changes immediately. Your next bill will be based on metered usage rather than rateable value.

In rare cases where it is not practical to fit an external meter (for example, in a block of flats with shared supply pipes), the company may offer you an assessed charge instead — a bill based on the average metered usage for your household size in the area. This is often still cheaper than the rateable value charge.

Remember the 24-month trial: if your metered bills turn out to be higher, you can revert to unmetered billing within two years of the meter being installed. There is no risk in trying.

Water bills vary widely across England and Wales because each regional company sets its own charges (subject to Ofwat regulation). Below are the average combined household bills for 2025–26.

If you live in a high-cost area like South West Water, the savings from switching to a meter or reducing usage are proportionally larger. Households in the South West region can also apply for the WaterSure South West scheme, which offers additional bill caps.

WaterSure is a government-mandated scheme that caps your metered water bill at the average household bill for your water company area. It is designed to protect low-income households who cannot reduce their water usage for medical or family reasons.

Who qualifies for WaterSure?

You must have a water meter and meet both of the following conditions:

• You or someone in your household receives a qualifying means-tested benefit (Universal Credit, Pension Credit, Income Support, income-based Jobseeker’s Allowance, or income-related Employment and Support Allowance).
• You have a high essential water need — either because you have three or more children under 19 living at home, or because someone in the household has a medical condition requiring extra water use (such as kidney dialysis, Crohn’s disease, or eczema requiring frequent bathing).

If you qualify, your bill is capped so you never pay more than the average bill for your area. Given that the average is £473, this could save a large family or medical-needs household several hundred pounds per year.

Apply directly through your water company. Most have an online application form, or you can call their customer services team.

Your water bill includes a charge for surface water drainage — the cost of removing rainwater from your property via the public sewer system. If your property’s rainwater does not drain into the public sewer (for example, it soaks into your garden, drains into a private soakaway, or runs into a watercourse), you may be entitled to a rebate.

How much could you save?

The surface water drainage element of your bill is typically £30–£80 per year. If none of your rainwater enters the public sewer, you can claim a full rebate. If only some of your property drains privately, you may get a partial rebate.

How to claim

1. Check your bill to see if you are being charged for surface water drainage (most households are).
2. Assess whether your property’s rainwater actually enters the public sewer system, or drains elsewhere.
3. Contact your sewerage company to apply for the rebate. You may need to provide photos or a simple description of your drainage arrangements.

This is one of those small, often-overlooked savings that most households never think to claim. If you have a large garden, a gravel drive, or a soakaway — it is well worth checking.

If you are on a water meter, every drop you save translates directly into a lower bill. Even if you are unmetered, reducing water usage is good practice (and helps if you later switch to a meter). Here are the most effective steps:

In the bathroom (the biggest water user)

• Shorten your shower by one minute: saves around 12 litres per shower, or £25–£35 per year for a family of four.
• Fix dripping taps: a single dripping tap can waste over 5,500 litres per year — that is roughly £15 on a metered bill.
• Install a dual-flush toilet: older single-flush toilets use 13 litres per flush. A modern dual-flush uses 4–6 litres. Your water company may offer a free cistern displacement device (a ‘save-a-flush’ bag) as a quick alternative.

In the kitchen

• Only run the dishwasher when full: a full load uses less water than washing the same items by hand.
• Use a washing-up bowl: saves around 10 litres per wash compared to running the tap continuously.

In the garden

• Use a water butt: collecting rainwater for the garden is free and can save up to 5,000 litres per year. Your water company may sell subsidised water butts.
• Water plants in the early morning or evening: reduces evaporation and means more water reaches the roots.

Collectively, these measures can reduce a metered household’s water consumption by 20–30%, translating to savings of £80–£140 per year at current rates.
