Unusually high bill

Unusually high bill

There is often a simple reason why your bill or meter reading is higher than usual. See our list below for some common causes.


The Covid-19 pandemic means many of us are spending more time at home than usual. If you are now working from home and/or home schooling, you might find that your water use has gone up. Our water saving tips could help to lower your future bills. 

If your income has been affected by Covid-19 and you are struggling to pay your bill, we can help.  

Estimated meter readings 

If your previous meter reading was an estimate, we may have underestimated how much water you used in the last billing period. It may mean your most recent bill is higher than your previous estimated bill.

You should also check how many days the bill covers; most bills cover six months, but it could be less or more than that. If your meter reading was an estimate, you can submit a meter readingyourself to make sure your bill is accurate.

More people at home

Changes at home, even for a short period, can have an impact on how much water you use. These changes include working from home, retirement, having a baby or hosting guests. The average person uses 140 litres of water each day.

By using our handy water usage calculator GetWaterFit, you can order a free water-saving pack to help you use less water.

New appliances

If you have recently installed new appliances, such as a washing machine or dishwasher, they may be using more water than your old ones. A new power shower will also use a lot more water than a standard electric shower.

We recommend using your appliances’ eco settings to use as little water and energy as possible. See our water saving tips for more ways to save water in your home and garden.

Time of year

Watering your garden during summer can result in a higher bill. Use less water in the garden by installing a water butt, using a watering can instead of a hosepipe and letting your lawn go brown.


A leaking toilet is hard to spot but can waste over 200 litres of water a day. Leaking pipes and taps could also cause an unusually high bill. See our advice on how to check for leaks and if you find one, you may be entitled to a leakage allowance. 

Renovating your home

Recent renovation work in your home could cause a spike in your water bill. You may have used more water than usual when cleaning up after plastering or painting.
