Ofwat is today releasing new figures that shed light on the water industry’s performance on reducing leakage. The provisional figures show that three quarters of the companies are meeting their leakage targets and some have reduced leakage by more than 10% over the past two years.
Ofwat has strongly pushed companies to cut leakage over recent years, including challenging the sector to reduce leakage by at least 16% in the 5 year period up to 2025.
Today’s figures show that progress has been made, with industry wide leakage being reduced by 11% since 2017-18, heading towards the target of a 50% reduction by 2050. However, there is more that can be done.
David Black, Ofwat CEO commented:
“It is encouraging to see progress in tackling leakage, with some companies making significant reductions. We welcome the improvements companies have made in reducing leakage and it’s encouraging to see things heading in the right direction. That said, there is much further to go. In the drier weather we are all acutely aware of the impact of climate change and the value and importance of water. Customers rightly expect water companies to lead by example in caring for water and helping households to do the same.”
Water company leakage reduction (based on 3 year averages from the 2019-20 baseline)
|Water company||Leakage reduction*|
|South East Water||3.3%|
|South Staffs Water||7.2%|
|South West Water||6.0%|
*Figures are 3-year averages taken from water company annual performance reports (APRs). This includes provisional figures for 2021/22. Water companies will all be starting from different baseline leakage positions. Targets are set considering the water resource challenges within each companies’ region.
These provisional figures from the water companies will be validated by Ofwat over the coming months. Further detail on water company performance on leakage will be available when Ofwat publishes the Service and Delivery Report 21-22 later this year.
Notes to editors
- Past performance on leakage can be seen in the Service and Delivery Report for 2020-21, published November 2021.
- An example of previous enforcement action on leakage includes this case against Thames from 2017/2018.
- We welcome feedback form all stakeholders on our draft methodology by 7 September 2022. We will take account of these views in finalising the methodology before the end of the year.
