There is often a simple reason why your bill or meter reading is higher than usual. Use our checklist below to find out why it has increased.


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.  

Meter reading 

If your meter reading was an estimate, we may have underestimated how much water you use. It may mean your most recent bill will be higher than the previous estimated bill.  

The other thing to check is how many days the bill covers; most bills are six months but it could be less or more than that. Find out how to read and submit a meter reading

Change in household size 

A guest staying in your home, a new addition to the family or a new housemate could cause your bill to go up. On average each person uses around 150 litres of water a day. Installing water saving products in your home could lower your future bills. 

New appliances 

New appliances like washing machines and dishwashers may be using more water than your old ones. To find out more check with your manufacturer. A new power shower will use a lot more water than a standard electric shower. See our water saving tips on how to reduce your water use.

Water use outside the home 

Watering the garden in the summer can result in a higher bill. One way to save money is to buy a water butt.  

Check for leaks 

A leak could be the cause of your higher water bill - see our advice on how to check for leaks. You may be entitled to a leakage allowance
