💧 Cut Water Bills in the UK: Smart Tips to Save Every Drop (and Pound)
As household budgets continue to be squeezed, more UK residents are looking for smart ways to cut their water bills. While water isn’t metered in every home, millions could be overpaying, especially if you live alone or in a small household.
This guide explains how UK billing works, how to get a meter, and how to slash your usage — without sacrificing comfort.
💡 Understanding How UK Water Bills Work
In the UK, water charges are typically billed in one of two ways:
1. Unmetered Charges (Rateable Value)
You pay a fixed annual fee based on your home’s rateable value — not on actual usage.
2. Metered Charges
You pay for the exact amount of water you use (measured in cubic metres), plus a standing charge.
Whether you’re metered or not, your water bill will cover two services:
-
Water supply (clean water into your home)
-
Sewerage/wastewater (used water out)
Each UK region has different water suppliers — use Water UK’s Supplier Checker to find yours.
🧮 Would a Water Meter Save You Money?
The general rule: if there are more bedrooms than people in your home, a meter could cut your bill significantly.
Example:
-
1 or 2 people in a 3-bedroom home could save £100–£300 a year
-
Big households in small homes may pay more on a meter
You can use a free meter calculator at CCW (Consumer Council for Water) to estimate potential savings.
If you switch to a meter, most companies offer a 2-year trial — if you’re worse off, you can switch back.
🚿 Top Tips to Cut Your Water Usage (and Bills)
Whether you’re on a meter or not, using less water is always a win — for both your wallet and the planet.
💦 1. Install Water-Saving Devices
Most water companies provide free gadgets:
-
Dual-flush toilet converters
-
Shower timers
-
Tap aerators
-
Save-a-flush bags
Request them directly from your supplier’s website.
🛁 2. Swap Baths for Showers
An average bath uses 80 litres, while a short shower can use just 35–50 litres — even less with a water-efficient shower head.
🚽 3. Don’t Flush Unnecessarily
Only flush the 3 Ps: pee, poo, and paper. Every flush costs water — avoid using it like a bin.
🧼 4. Fix Dripping Taps and Leaks
A dripping tap can waste up to 5,500 litres a year. That’s money literally going down the drain.
🍳 5. Use a Bowl to Wash Dishes
Running water for 10 minutes can waste 100+ litres. Fill a bowl instead to save litres with every wash-up.
🌱 6. Water the Garden With Rainwater
Install a water butt to collect rain from your gutter — perfect for watering plants without using mains water.

🧾 Check If You’re Paying Sewerage Charges on Surface Water
Many households are unfairly charged for draining rainwater into public sewers — even if they use soakaways or private drainage.
If you don’t use the public system, you may be eligible for a Surface Water Drainage rebate, potentially worth £30–£50/year.
Apply via your water provider’s website.
