How to Save Money on Your Water Bill
Share
Water bills in the UK are rising, and many households and businesses are looking for ways to cut costs. Whether you’re on a water meter or a standard rate, making small changes can add up to big savings. Reducing your water usage doesn’t just help your wallet, it also helps conserve water, which is becoming an increasingly important issue.
From simple habit changes to investing in water-saving technology like rainwater harvesting systems, there are plenty of ways to lower your water bill. This guide will take you through the most effective strategies so you can start saving money today.
1. Monitor Your Water Usage
If you want to save money on your water bill, the first step is understanding how much you use. If your home has a water meter, you’re charged for the exact amount of water you consume. Keeping an eye on your usage can help you spot areas where you can cut back.
Check your water meter regularly and compare your bills over time. If you notice a sudden increase, you might have a hidden leak or an inefficient appliance. Even if you don’t have a meter, monitoring your water habits can still help you make informed decisions about reducing waste.
Most UK water suppliers offer online tools to help you track your water consumption and identify potential savings.
2. Fix Leaks and Dripping Taps
Leaks are one of the biggest causes of unnecessary water waste. A dripping tap may not seem like a big deal, but it can waste up to 5,500 litres of water per year—and that’s water you’re paying for.
A leaking toilet is even worse, sometimes wasting hundreds of litres per day without you noticing. If you hear your toilet running constantly or see damp patches around pipes, it’s worth investigating.
Most tap leaks can be fixed by replacing a washer, while toilet leaks usually require a new flush valve. These are cheap and easy fixes that can prevent water (and money) from going down the drain.
3. Upgrade to Water-Efficient Appliances
Modern appliances are designed to use less water without sacrificing performance. If you’re serious about cutting down your water bill, upgrading to more efficient models is one of the best long-term solutions.
Dual-flush toilets – Use up to 50% less water per flush than older models.
Water-efficient washing machines – Newer models use significantly less water per cycle.
Dishwashers with eco settings - These use far less water than washing up by hand.
Low-flow showerheads and taps - Maintain good water pressure while using less water.
Although these upgrades require an upfront investment, they quickly pay for themselves through lower water bills.
4. Change Your Daily Water Habits
Making small adjustments to your daily routine can significantly reduce your water bill. Here are some simple but effective changes:
- Turn off the tap while brushing your teeth. This can save 6 litres per minute.
- Take shorter showers. Cutting your shower time by just two minutes can save over 4,500 litres per year.
- Use a basin instead of running water when washing dishes.
- Only run your washing machine and dishwasher when they are full.
- These simple changes cost nothing and can have an immediate impact on your water usage.
5. Collect and Use Rainwater
One of the most effective ways to reduce your reliance on mains water is by collecting and using rainwater. It’s completely free, and with the right system in place, you can use it for watering your garden, washing your car, and even flushing your toilet.
How Does Rainwater Harvesting Help Save Money?
- Reduces the amount of mains water used for outdoor and household tasks.
- Lowers your water bill if your home is metered.
- Provides an alternative water source during hosepipe bans or dry periods.
- Installing a rainwater harvesting tank is a great way to store rainwater for later use. There are many options available, from small garden water butts to large underground storage tanks that can be connected to your plumbing.
Even smaller rainwater harvesting tanks can save thousands of litres of mains water per year, particularly in summer when water demand is higher. Larger rainwater tanks can be used for more substantial water storage, helping homeowners and businesses save even more.
6. Use Mulch and Drought-Resistant Plants in Your Garden
If you spend a lot of money watering your garden, making a few changes to your landscaping can help cut costs.
Adding mulch to flower beds helps the soil retain moisture for longer, meaning you won’t need to water as often. It also prevents weeds from growing, which compete with your plants for water.
Choosing drought-resistant plants like lavender, rosemary, and ornamental grasses can also reduce your garden’s water needs. These plants thrive in the UK climate while requiring much less water than traditional lawn grass and thirsty flower varieties.
By designing your garden with water conservation in mind, you can maintain a beautiful outdoor space while cutting down on your water bill.
7. Consider a Greywater Recycling System
Greywater recycling systems collect water from sinks, showers, and washing machines and reuse it for flushing toilets or garden irrigation. These systems can significantly reduce your reliance on mains water, especially in larger households.
Although they require an upfront investment, greywater systems can lead to long-term savings, making them a worthwhile consideration for anyone looking to reduce their water bill.
8. Check If You Qualify for Free Water-Saving Devices
Many UK water suppliers offer free water-saving devices to help customers cut down on their water usage. These can include:
- Water-saving showerheads – Reduce water flow without affecting pressure.
- Tap aerators – Mix air with water to maintain strong flow while using less water.
- Cistern displacement devices – Reduce the amount of water used per toilet flush.
Check your local water supplier’s website to see if you can get these devices for free. They are simple to install and can help lower your water bill with minimal effort.
9. Compare Water Tariffs and Consider a Meter
If you’re on an unmetered water supply, switching to a meter could save you money. Households with fewer occupants than bedrooms often benefit the most from making the switch.
Most water companies allow a trial period where you can switch back to an unmetered tariff if you find that a meter doesn’t save you money. Contact your water provider to find out whether a meter might be the right option for your household.
There are plenty of ways to reduce your water bill in the UK, from changing daily habits to investing in water-saving solutions. Fixing leaks, upgrading to efficient appliances, and harvesting rainwater are all effective ways to cut costs.
If you’re serious about reducing your water bills, a rainwater harvesting tank is a smart and sustainable choice. By making use of free rainwater, you can significantly lower your mains water usage while also helping the environment.
