PN 04/20: Ofwat makes submission to CMA following company appeals


Ofwat has today made its submission to the Competition and Markets Authority after four of the 17 water companies appealed to the CMA against the outcome of Ofwat’s recent price review.

The price review sets the outcomes water companies should deliver for customers and the environment, and the price that customers will pay over the next five years.

Since 2015, Ofwat has been clear and consistent in saying, in this price review companies needed to increase efficiency and improve performance to deliver more for customers. This is particularly important to address the challenges for the future – such as climate change and population growth – and the shortcomings of the past – such as operational failures and concerns that, in some cases, more attention has been paid to taking money out for shareholders than delivering for customers.

To support companies in making this transformation, Ofwat’s price review allows for significant expenditure of over £50bn between 2020-25, of which £13bn is explicitly dedicated to improving services, resilience, and the environment. The price review also allows £1bn of investment that wasn’t requested by the companies to address long-term challenges.

Improved service and investment for the future can be delivered while reducing customers’ bills because Ofwat is pushing for greater efficiency in companies and passing through lower financing costs. An important principle in the price review is that customers shouldn’t pay for inefficiency or to top-up funds to cover companies’ previous shortcomings and help them catch up with others.

Anglian Water, Bristol Water, Northumbrian Water and Yorkshire Water have challenged Ofwat’s approach and want customers to pay more or receive a lower standard of service. Ofwat will set out how its detailed analysis of operational best practice, companies’ historic performance and business plans, and evidence of returns in capital markets shows this is unjustified.

Rachel Fletcher, Ofwat Chief Executive, said:

“Our aim is to get the best outcome for customers and the environment, and a fair return for investors, both now and the long term. After extensive and detailed analysis in the price review, four companies have refused to accept our view on what customers should pay and the standards they should expect over the next five years. And so we welcome the opportunity for the CMA, with its independent expertise, to settle the matter once and for all.

“As this review carries on, we will press ahead with our work to transform the sector: in its performance, its preparedness for facing future challenges like climate change and population growth, and its work to rebuild trust by showing the value it can create for society and the environment.”


Our final determination gives Anglian Water £5.6bn over the next five years to improve services to customers and the environment, 17% more than it has spent historically.

Anglian Water customers would see bills fall by 10%, they would see investment of £305 million to help move water from other areas in the region, they would see pollution incidents fall by a third, and carbon emissions down by 10%

Our final determination provides Bristol Water with £462 million over the next five years Their customers would see bills fall by 15%, they would see over £8 million invested to improve water mains resilience, they would see 48,000 water meters installed, and they would see plans for 85% of vulnerable customers to be left satisfied with the help they receive.

Our final determination provides Northumbrian Water with £2.9bn over the next five years, 5% more than it has spent historically. Their customers would see bills fall by £26, they would see greenhouse gas emissions fall by 28%, they would see an increase in bathing spots rated good or excellent, and they would see more than 450,000 smart meters be installed.

Our final determination gives Yorkshire Water £4.4bn over the next five years, 10% more than it has spent historically. Their customers would see bills fall by 9%, they would see almost a third more land enhanced in the region, they would see 50% more customers on social tariffs and WaterSure, and they would see pollution incidents fall by 41%.
