How much are water bills going up by where you live? UK water firms to hike prices of bills - which areas will be paying the most?

Last year regulator Ofwat said it will allow companies to raise average bills by £31 a year, or £157 in total, over the next five years to £597 by 2030 to help finance a £104 billion upgrade for the sector. That represents a 36% increase before inflation, which will be added on top.

Households will be hit particularly hard from April with an average hike of £86 or 20% front-loaded into the coming year, with smaller percentage increases in each of the next four years. Consumer groups warned that the increases were “more than what many people can afford”.

This week, water companies United Utilities and South West Water have confirmed bill increases of 32% and 23%, respectively, over the coming five years. United Utilities, which serves customers in Manchester and Liverpool, and South West Water’s parent company Pennon said they had agreed the bill increases negotiated with regulator Ofwat last year.

Scottish Water has also announced this month that water bills will rise by 9.9% in April. It said this means the average monthly household bills for water and waste water services will increase by £3.68 per month or £44 per year from April 1.
