Water bills are set to climb by an average of £157 over the next five years, the industry regulator has confirmed.

Ofwat's figures have angered consumer groups, who have criticised many water firms' records on sewage spills and water leaks.

The amount bills are going up by differs depending on each individual water company. But how has this happened - and how much more will people have to pay?

Why are water bills increasing?

Water firms in England and Wales submit plans to Ofwat every five years on how much they will raise water bills.

Ofwat then negotiates with the companies over how much bills can go up by and sets limits, before publishing its final decision.

For the next five years, Ofwat has granted an average bills increase of 36%, or £31 a year until 2030. The regulator added this was, on average, £8 lower per year compared to what companies proposed in their plans.

Ofwat said it had made sure bills were "fair", and not higher than they need to be. If companies do not meet their targets they must return money to customers, it added.
