When you are sorting out your monthly household budget, it is easy to focus all your attention on gas and electricity. Energy prices tend to dominate the headlines, but your water bill is another area where costs can quietly creep up if you are not paying attention. The good news is that unlike some fixed council tax or broadband charges, your water bill is a utility you can often exert direct control over.
By making a few practical adjustments around your home, you can significantly reduce the amount of water you use. Because a large chunk of your water usage involves heating it up—think showers, baths, and washing machines—cutting back on water also means trimming your energy bills. It is a win-win situation. You do not need to make drastic lifestyle changes either; small, consistent habits add up over time.
Here is a practical guide to help you strip back your household water consumption and keep a few extra pounds in your bank account.
Before you start changing your habits, you need to understand how exactly you are paying for the water you use. The way you are billed usually dictates how you should approach saving money.
Understanding Unmetered vs Metered Bills
In the UK, households generally fall into two camps: those on a standard unmetered tariff and those with a water meter. If you are unmetered, your bill is based on the somewhat archaic ‘rateable value’ of your home, which was likely assessed decades ago. This means you pay a fixed amount every year, regardless of whether you use ten litres a day or a thousand.
If you have a water meter, however, you pay for exactly what you use. The meter tracks every drop that comes through your pipes. If you are on a meter, every single water-saving tip you implement will translate directly into a lower bill.
The Magic of the Water Meter
If you do not currently have a water meter, you might want to look into getting one. A widely accepted rule of thumb is that if there are more bedrooms in your house than there are people, you will likely save money by switching to a meter. For example, if you are a couple living in a three-bedroom house, you are probably paying more than you need to on a fixed tariff.
You can use the Consumer Council for Water’s free online calculator to get an estimate of whether a meter would make financial sense for you. Most water companies in the UK will install a meter for free. If they cannot fit one due to the pipework in your home, you can ask to be put on an ‘assessed charge’, which is often much cheaper than the standard unmetered rate.
Finding Hidden Leaks
If you already have a meter and your bills still seem unusually high, you might be dealing with a leak. A dripping tap is obvious, but underground leaks or a leaking toilet cistern aren’t always visible.
To check for hidden leaks, locate your water meter and take a reading just before you go to bed. Do not use any water overnight—no toilet flushes, no washing machines on a timer. Check the meter again first thing in the morning. If the reading has gone up, you have a leak somewhere on your property that needs investigating. Fixing these quickly stops you from paying for water that is simply draining away.
Simple Swaps in the Kitchen
The kitchen is one of the busiest rooms in the house, and naturally, it is a place where water is heavily used. Fortunately, it is also a place where you can make immediate changes without feeling any negative impact.
Rethinking the Washing Up
We all know the familiar routine of rinsing dishes under a running tap before setting them on the drainer. A running tap can waste up to nine litres of water a minute. Instead, employ the traditional British washing up bowl. Fill it once with hot, soapy water to wash your plates, and if you really must rinse them, use a second bowl of clean water rather than the flowing tap.
If you just need to wash a single mug, resist the urge to do it under a fully open tap. Use a small splash of water to loosen any residue, give it a scrub, and rinse quickly.
Boiling Only What You Need
It is a very common habit to fill the kettle to the brim, even if you are only making one cup of tea. Overfilling the kettle not only wastes the water itself but also wastes the electricity or gas required to heat it. Get into the habit of measuring out the water you need. You can use your mug to measure the exact amount into the kettle. This simple change will lower your water usage and noticeably reduce your electricity consumption over the year.
Mastering Your Washing Machine and Dishwasher
Modern dishwashers are actually remarkably efficient, often using less water to wash a full load than it would take to wash the same amount by hand. However, the key phrase here is ‘full load’. Running a dishwasher when it is only half full is a waste of both water and energy. Wait until it is packed properly before turning it on, and use the ‘eco’ setting if your machine has one. It might take longer, but it uses water much more efficiently.
The same rule applies to your washing machine. A standard washing machine cycle uses roughly 50 litres of water. Try to hold off until you have a full basket of laundry rather than doing multiple small washes throughout the week. When you do wash, sticking to a 30-degree cycle will help cut down your related energy costs.
Trimming Costs in the Bathroom
The bathroom accounts for roughly two-thirds of the average household’s water usage. From daily hygiene to toilet flushing, a massive amount of clean drinking water goes quite literally down the drain. This means it is the best room in the house to target for savings.
The Great Shower vs Bath Debate
A standard bath uses around 80 litres of water. By contrast, a short shower uses significantly less. However, the exact amount shifts depending on the type of shower you have and how long you spend in it. If you have a traditional gravity-fed shower, a five-minute wash will use perhaps 35 to 40 litres.
On the other hand, if you have a power shower that pumps water out at a high flow rate, spending ten minutes under the spray could easily use more water than a full bath. Try to keep your showers to around four minutes. You can buy cheap waterproof sand timers, or simply set an alarm on your phone, to help you get in and out efficiently.
Upgrading to a Water-Saving Showerhead
If you are replacing your showerhead or just looking to improve efficiency, a regulated or aerated showerhead is a brilliant investment. These devices mix air with the water, giving you the sensation of a powerful shower while actually dispensing much less water.
Be aware, though, that if you have an electric shower, you usually should not attach an aerated showerhead, as it can cause the water to back up and damage the heating element. Check your manufacturer’s instructions to be sure.
Taming the Toilet Flush
Around 30% of the water used in a home is literally flushed down the loo. Older toilets can use up to 14 litres of water per flush, which is a massive drain on your metered bill. If you have an older toilet, you don’t necessarily have to replace it. You can place a displacement device, like a ‘Save-a-Flush’ bag or a heavy plastic bottle filled with water, into the cistern. This simple trick displaces water, meaning the tank fills with a few litres less every time.
If you have a modern dual-flush toilet, make sure everyone in the house knows how to use it properly. The smaller button is for liquid waste and uses around three to four litres, while the larger button is for solid waste and uses six to eight litres. It sounds basic, but many people just press both buttons simultaneously out of habit.
Turning Off the Tap
It is advice you have likely heard since childhood, but turning off the tap while brushing your teeth is one of the easiest ways to save water. Leaving it continuously running can waste up to 24 litres of water every time you brush. Wet your toothbrush, turn the tap off while you clean your teeth, and turn it back on just to rinse. Exactly the same logic applies to shaving; put a little water in the sink rather than leaving the hot tap running.
Being Water-Wise in Your Garden
During the British summer, water usage can spike dramatically as we try to keep our lawns green and our hanging baskets alive. Unfortunately, using sprinklers and hosepipes will send a metered water bill through the roof.
Installing a Water Butt
One of the most effective things you can do for your garden is to install a water butt. Attached to your guttering, a water butt captures the rain that falls on your roof. Given the predictability of the UK weather, you will typically find it fills up quite easily outside of high summer.
Using rainwater is actually much better for your plants than using water straight from the tap, as it does not contain the chlorine used in the mains supply. Plus, every watering can you fill from the butt is a watering can you haven’t paid for via your meter.
Watering at the Right Time
If you do need to use tap water in the garden, timing is everything. Watering your garden in the middle of a hot afternoon is terribly inefficient, as much of the water simply evaporates before it can reach the roots of the plants. Instead, water your garden either early in the morning or late in the evening.
Ditch the sprinkler entirely. A garden sprinkler can use up to 1,000 litres of water in a single hour—that is more than a typical family of four uses in an entire day inside the house. Use a standard watering can to target the roots of specific plants so nothing goes to waste.
Choosing Drought-Resistant Plants
When you are planning your garden or buying new plants from the garden centre, consider picking species that do not require constant watering. Lavender, rosemary, and various types of ornamental grasses thrive in drier conditions. Furthermore, applying a layer of mulch or bark chippings over your flowerbeds helps to lock moisture into the soil, reducing the need for artificial watering even during a dry spell.
Free Gadgets and Extra Support
You do not necessarily have to spend money to save money. There is plenty of free help available to help cut your water usage, and your supplier is often required by the regulator to assist you.
Ordering Free Water-Saving Devices
Many UK water companies partner with organisations like ‘Save Water Save Money’ to offer free water-saving gadgets to their customers. You can usually go onto your water provider’s website, enter your postcode, and order a range of items at no cost.
These freebies often include shower timers, tap aerators (which screw onto your bathroom taps to reduce the flow rate), and the aforementioned cistern displacement bags. Taking a few minutes to request these items can lead to immediate and permanent savings on your utility bills.
Social Tariffs and WaterSure
If you are struggling to pay your water bill, it is always worth checking what financial support is available. All water companies in England and Wales offer social tariffs, which can significantly reduce bills for low-income households or those receiving certain benefits.
Additionally, if you are already on a water meter, receive certain benefits, and either have three or more children under 19 living at home or a medical condition that requires the use of a lot of water, you might qualify for the WaterSure scheme. This scheme caps your metered bill so you will not pay more than the average household bill for your region. Do not hesitate to contact your water company directly to see if you are eligible for these schemes; they have dedicated teams to help customers navigate their options.
Changing Your Habits Gradually
You do not have to tackle every single one of these points on day one. Trying to micromanage your household’s water usage all at once can just cause unnecessary stress. Start with the easiest changes, like turning off taps when brushing teeth, waiting for full loads to run the washing machine, and claiming your free water-saving gadgets from your supplier.
Once those routines become second nature, you can start looking at shorter showers or installing a water butt in the garden. By taking a steady, practical approach, you will find your metered water bill slowly but surely shrinking. It is a straightforward way to keep your household expenses grounded and keep your budget firmly under your own control.
