How to Reduce Your Water Bill

Stop Wasting Money Every Time You Turn on a Tap

The average London household spends hundreds of pounds on water every year — and a surprising amount of that goes straight down the drain. With a few smart plumbing fixes and simple daily habits, you can cut your water bill by up to 30% without any noticeable change in comfort. Here's exactly how to do it.

Fix Leaks Before They Drain Your Budget

A dripping tap might seem trivial, but it can waste over 5,000 litres of water per year. That's not just bad for the environment — it's money you're paying for water you never use.

Check under sinks, around the base of toilets, and along visible pipework for any signs of moisture or staining. Even a slow, silent leak can add up significantly over weeks and months.

If you spot a drip or notice your water meter ticking over when nothing is running, call a qualified plumber to investigate. Catching leaks early is one of the fastest ways to reduce your bill.

Upgrade to Water-Efficient Fixtures

Older taps, showerheads, and toilets use far more water than modern equivalents. Switching to water-efficient fixtures is a one-time investment that pays back year after year.

Consider making these upgrades throughout your home:

• Install a low-flow showerhead to cut shower water use by up to 50%
• Fit aerator attachments on kitchen and bathroom taps to reduce flow without reducing pressure
• Replace an older toilet with a dual-flush cistern to use only the water you need
• Install a thermostatic shower valve so you're not running cold water waiting for the temperature to adjust
• Use push taps in cloakrooms to prevent taps being left running accidentally

Many of these upgrades are straightforward and affordable. A professional plumber can fit them quickly and ensure everything is properly sealed and compliant.

Change Your Daily Habits

You don't need to spend a penny to start saving water immediately. Small behavioural changes across the household can make a genuine difference to your monthly bill.

Turn the tap off while brushing your teeth, take showers instead of baths, and only run the dishwasher or washing machine when they're fully loaded. These habits alone can save thousands of litres per year.

Encourage everyone in the household to be mindful. Even shaving a minute off your shower time can reduce water consumption noticeably when multiplied across a family over a full year.

Check Your Boiler and Hot Water System

An inefficient hot water system forces you to run taps longer while waiting for warm water to arrive — wasting both water and energy. If you're waiting more than 30 seconds for hot water at your tap, your system may need attention.

A poorly set boiler thermostat or a failing circulator pump can cause this issue. Having your boiler and hot water system serviced annually helps ensure everything is running efficiently.

Net-Plumbers' Gas Safe registered engineers can assess your system and recommend practical improvements that reduce both your water and energy bills simultaneously.

Get a Water Meter Installed

If you're still on a rateable value water charge, switching to a metered supply could reduce your bill significantly — especially for smaller households. A meter means you only pay for what you actually use.

Contact your water supplier to request a meter. In most cases, installation is free and you can switch back within a trial period if it doesn't save you money.

Once metered, you'll also have a baseline to notice unusual spikes in usage, which can alert you to hidden leaks before they become costly problems.
