Five water firms prevented from increasing bills as much as they wanted
Five major water companies have been significantly reined in by the UKโs competition watchdog, which has slashed the amount they can add to customer bills.
Anglian Water, Northumbrian Water, South East Water, Southern Water, and Wessex Water will now be permitted to raise an additional ยฃ463m in revenue, a stark reduction from the ยฃ2.7bn they had initially sought.
This revised funding is projected to lead to an average 2.2 per cent increase in bills for customers of these five firms.
This comes on top of a substantial 24 per cent average hike already approved by the water regulator Ofwat.
The latest decision by the Competition and Markets Authority (CMA) represents a further cut from the ยฃ556m, or three per cent average increase, that had been provisionally granted in October.
The CMA stated its intention was to strike a balance between minimising the financial burden on households and ensuring suppliers have adequate funds to meet their legal obligations, particularly concerning environmental standards and drinking water quality.
While acknowledging the necessity for some additional investment, the regulator ultimately rejected the majority of the companies’ funding requests.
Kirstin Baker, chair of the independent group appointed by the CMA, said: โWeโve rejected most of the bill increases water companies asked for but allowed limited extra funding where thatโs genuinely needed, balancing concerns about affordability with the need to secure our water supplies and cut pollution.
โA significant part of this extra money reflects market movements since Ofwatโs decision.โ
The five companies had requested approval to raise more money through customer bills after arguing that Ofwatโs decision left them unable to meet the regulatory requirements set out for them.
This refers to a decision made in late 2024, when Ofwat said it would allow water firms to raise bills by an average of ยฃ157, or 36 per cent, over the next five years to help finance investment into crumbling infrastructure.
The amount that customer bills are going up varies between each supplier.
Public outrage has mounted over the widespread pollution of waterways, particularly as firms seek to fund upgrades following decades of perceived underinvestment.
Regulator Ofwat has already sanctioned water companies to raise bills by 36 per cent between 2025 and 2030, with a substantial portion โ 20 per cent, or an average of ยฃ86 โ applied to last April’s annual increase.
The Consumer Council for Water (CCW) previously warned that customers were โimpatient for change and need to see compelling evidence their money is being well spentโ.
