MARTIN Lewis has urged households to do a simple check that could knock £1,000s off their water bills.
The money expert told audience members about the trick on The Martin Lewis Money Show live this week.
Households will see the largest hike in their annual water bills in almost 20 years when they rise to an average of £448 this spring.
From April 1, water bills will rise by roughly 7% for households in England and Wales and by 5% for those in Scotland.
Water UK said the increase would see customers pay around £1.23 per day on average, from April in England and Wales.
This is an increase of 8p per day, or an average of £31 more than last year’s charges.

However, one thing the MoneySavingExpert.com (MSE) founder said people could do is to check if they're entitled to a water meter as it could knock money off their bill.
One money saver said they're saving £1,000 on their water bill by switching to a water meter.
She said: "Following your advice, we switched to a water meter now our children have left home, and our bills have gone from £1,360 per year to £325 - saving over £1,000 per year."
All households need to first, Martin said, is check if they've got more or the same number of bedrooms than people living in their home.

Martin said: "Water bill are based on the rateable value which is a proxy for the house value."
This means you could be a big bill even if you don't use that much (as there's less of you).
If you think you qualify, Martin said you can head to The Consumer Council for Water website and use its free water meter calculator.
It will ask you questions about water use and estimated costs.
Households can then request a fitting from their water company.
"If they [your water company] say they can't fit a water meter because it's not practicable, then ask for an assessed charge which could tell you roughly what you pay on a water meter if you had one.
The money expert added: "And if that's cheaper then you can just pay the lower amount.
"If you're disabled, if you've got related medical issues or you're on benefits, speak to your water firm - you may be able to get money back or a cheaper tariff."
However, if you do use a lot of water then it makes no sense to have a meter as your bills could go up.
For example, if you have a big family and more people than bedrooms or simply use lots of water-intensive appliances like washing machines or dishwashers, a fixed fee will be better for you.
Having a water meter doesn't help with the standard charge that's based on where you live either, but it can help you cut down the costs of your personal usage at home.
Part of that is how long you spend in the shower too.
According to Uswitch, you could cut £70 from your energy bills and reduce your water bills too by reducing your wash time.
And leaving the water running while you brush your teeth could add £60 a year to your bills says Octopus.
The same goes for washing dishes, be sure you turn the tap off as if you’re doing it in the sink, leaving it running will add £25 to your annual bill.
