People in Milton Keynes could save £800,000 in bills through being more water efficient, according to a new study.
The figures come from a study of 86,000 homes by the Energy Saving Trust, which scrutinised the amount of water being used across the UK.
Simple tricks like cutting a minute off the time you shower in the morning, or stopping overfilling the kettle could save hundreds of thousands of pounds a year, says the trust.
Andrew Tucker, water strategy manager, said: “When people think of energy they think of heating and lighting, running electrical appliances or filling the car with petrol.
“It’s all too easy to turn on the tap and not think about the consequences...But hot water use contributes £228 to the average combined energy bill.”
Even something as simple as washing up by hand instead of using a dishwasher can increase bills, said Mr Tucker.
> The figures were compared to nearby towns including Bedford where £1.4million is lost and Luton where £1.6million is being wasted by consumers.
