The average household water and sewerage bill in England and Wales will fall by around £17 this year in line with new regulatory changes.
Water UK, which represents and works with the major water and sewerage service suppliers, has confirmed that from April, the average bill will drop from £413.33 to £396.60.
This follows an average rise of £8 in 2019/20 and a £9 increase in 2018/19.
Last year, regulator Ofwat announced that firms would need to reduce water bills by an average of £50 by 2025.
However, the reduction is only an average and some areas could still see bills go up in line with improvement works in their town or city.
It warned that under new guidelines, companies would also have to help customers who struggle to pay their bills, and cut leaks and pollution incidents.
If you're worried about expensive water bills, check if you could save more money by switching to a water meter instead.
Under the April changes, a household supplied by Northumbrian will see a substantial drop of £85 on average, while Wessex customers will enjoy bills dropping by 8% ‒ a drop of £40 a year.
However those who receive their supply from Yorkshire Water, will see their annual costs rise by an eye-watering 4%.
