About Us

Regulatory performance

Every year we publish information about our performance and you can find our full library of current and historic documents here.

We’re now in the fourth year of our business plan for 2015-20. We made 13 performance commitments in our plan - our Annual Performance Reports set out how well we’ve performed against them. It also includes other important regulatory accounting information.

In July 2018 we republished the summary versions of our Annual Performance Report for our customers to include comments from our Customer Challenge Group.


In addition, we also publish statutory accounting information for Severn Trent Water in our Annual Report and Accounts:
