Meeting the high hurdle to achieve a fast-track assessment


We submitted our business plan for the 2020–25 period in September 2018, and Ofwat published its initial assessment (IAP) on 31 January 2019, in which we were one of only three companies to achieve a fast-track assessment. This achievement reflects the transformation we have delivered in recent years as well as the quality of our plan.

Our plan received the highest overall grades for the sector, as can be seen in the table below. It was commended as high quality and industry-leading in many areas, including innovation, affordability and vulnerability, customer engagement, and resilience. We committed to deliver more for less for customers, with stretching service level targets alongside a significant bill reduction in real terms.

As part of the IAP, all three fast-track companies accepted targeted actions from Ofwat. There were areas of our plan where we were asked to commit to even more stretching targets, such as reducing leakage, a further 3 per cent reduction in total expenditure, and provide more information on our proposals. We will continue to work constructively with Ofwat through to our final determination in December 2019.

A fast-track assessment brings reputational, financial and procedural benefits. Most importantly, it gives us greater clarity earlier in the process, and we have committed a further £100 million investment in 2019/20 to make a flying start in delivering our plan.

Ofwat published its latest annual Company Monitoring Framework assessment, in which we retained the highest category of 'self-assurance'. We have achieved this three years in a row – the only company to do so – demonstrating the consistently high level of trust and confidence that customers and other stakeholders can have in the quality and transparency of our reporting.
