How to Save Money on UK Water Bills in 2026 – Complete Guide
Why Your Water Bill Matters More Than You Think
Water bills are one of those household expenses that many people simply accept without questioning. But with the average UK household paying around £400 a year for water and sewerage, there are genuine savings to be made if you know where to look. In 2026, water companies across England and Wales have implemented price changes as part of the Ofwat price review, making it more important than ever to understand your bill and take action.
The good news is that you do not need to make drastic lifestyle changes to see real savings. Small adjustments to how you use water, which tariff you are on, and how you manage your account can add up to significant reductions over the course of a year.
Understand Your Water Bill
Before you can save money, you need to understand what you are actually paying for. Most UK households are billed in one of two ways:
- Metered billing – You pay for the exact amount of water you use, plus a standing charge. This is generally the cheaper option for smaller households.
- Unmetered billing – You pay a fixed rate based on the rateable value of your home, regardless of how much water you use. This can be better for larger families.
If you are not on a water meter, it is worth requesting one. Most water companies in England and Wales offer free meter installation, and the general rule is that if you have more bedrooms than people living in your home, you will likely save money by switching to a meter.
Check If You Qualify for a Water Meter
Getting a water meter fitted is one of the quickest ways to cut your water costs. According to the Consumer Council for Water, households that switch to a meter save an average of £150 per year. Here is what you need to know:
- Meter installation is free in most of England and Wales
- You typically have two years to switch back if you find you are paying more
- If a meter cannot be physically fitted, you can request an assessed charge based on the number of people in your home
- Scottish Water customers can request a meter but may face an installation fee
Contact your water company directly to request a meter or use their online assessment tool to see if it makes sense for your household.
Switch to a Social Tariff
If you are on a low income or receiving benefits, you may qualify for a social tariff. Every water company in the UK is required to offer some form of financial assistance scheme, but the names and eligibility criteria vary. Some of the most well-known schemes include:
- WaterSure – Caps your bill at the average household rate if you receive certain benefits and have a high water use due to a medical condition or a large family
- WaterSure Wales – The Welsh equivalent of WaterSure, offered by Dwr Cymru Welsh Water and Hafren Dyfrdwy
- WaterDirect – For customers on certain benefits, payments are deducted directly from benefits at an affordable rate
- Company-specific social tariffs – Each water company offers its own reduced tariff for struggling customers, with discounts ranging from 25% to 90%
You can check your eligibility by contacting your water company or using the Consumer Council for Water website. Many people miss out on these schemes simply because they do not know they exist.
Reduce Your Daily Water Usage
Simple changes to your daily routine can significantly reduce your water consumption and lower your bills if you are on a meter. Here are the most effective ways to cut down:
In the Bathroom
- Install a water-saving showerhead – these cost as little as £10 and can save a family of four up to £80 a year
- Take shorter showers – cutting your shower from 8 minutes to 4 minutes saves around 40 litres per shower
- Fix dripping taps – a single dripping tap can waste over 5,000 litres of water a year, adding roughly £20 to your annual bill
- Use a dual-flush toilet or install a cistern displacement device – these are often free from your water company and save about 1 litre per flush
- Turn off the tap while brushing your teeth – this simple habit saves up to 6 litres per minute
In the Kitchen
- Only run the dishwasher when it is full – a modern dishwasher uses less water than washing by hand, but only if it is fully loaded
- Use a washing-up bowl instead of letting the tap run when washing dishes by hand
- Keep a jug of water in the fridge instead of running the tap until it goes cold
- Use the eco setting on your washing machine and dishwasher
- Thaw frozen food in the fridge overnight rather than under a running tap
In the Garden
- Install a water butt to collect rainwater – a 200-litre butt costs around £30 and provides free water for your plants all summer
- Water plants early in the morning or late in the evening to reduce evaporation
- Use a watering can instead of a hosepipe – a hosepipe uses around 1,000 litres per hour
- Choose drought-resistant plants that require less watering
- Use mulch around plants to retain moisture in the soil
Compare Water Companies If You Can Switch
Unlike energy suppliers, most households in England and Wales cannot choose their water company because the industry operates on a regional monopoly basis. However, if you live in an area where both a water company and a sewerage company operate, you may have limited options. The only truly competitive water market in the UK is for non-household customers in England.
What you can do is check whether you are being charged correctly. Water companies sometimes make billing errors, and you can request a review of your charges if you believe something is wrong. You can also check whether you are entitled to any refunds or credits on your account.
Claim for Sewerage Rebates
Many households are overpaying on sewerage charges without realising it. If your surface water (rainwater from your roof and driveway) does not drain into the public sewer, you may be entitled to a sewerage rebate. This can be worth £50 or more per year.
You may qualify for a rebate if:
- Your surface water drains into a soakaway, stream, or river rather than the public sewer
- You have a septic tank instead of mains drainage
- Your property is a flat or apartment where surface water is managed by the building management
Contact your sewerage provider to request a surface water drainage rebate. You may need to provide evidence of how your surface water drains, but the application process is straightforward and the savings are backdated.
Use Free Water-Saving Devices
Most water companies offer free water-saving devices to their customers. These can include:
- Cistern displacement devices for toilets
- Tap inserts to reduce flow rates
- Shower timers
- Shower regulators that limit water flow to 8 litres per minute
- Garden hose nozzles with trigger controls
Visit your water company’s website and look for their water-saving device section. You can usually order these items for free and they will be posted to your home. The savings from these devices alone can add up to £100 or more per year for a metered household.
Check for Leaks Inside and Outside Your Home
Hidden leaks can silently add hundreds of pounds to your annual water bill if you are on a meter. Common signs of a leak include:
- Unexpectedly high bills despite no change in usage
- Damp patches on walls, floors, or ceilings
- The sound of running water when no taps are on
- Green, lush patches in the garden during dry spells
- A spinning water meter dial when no water is being used
If you suspect a leak on your property, contact your water company. Many offer free leak detection services and some will even repair leaks on private pipework at no cost. If the leak is on the water company’s side of the supply pipe, they are responsible for fixing it at no charge to you.
Consider a Soakaway for Surface Water
If you currently have surface water draining into the public sewer and you install a soakaway, you can claim the surface water drainage rebate going forward. While installing a soakaway requires some initial investment, the annual savings on your sewerage bill typically pay for the installation within a few years.
