Draft determinations

We set high expectations for water companies at the 2019 price review.

We pushed them to go further than ever before, improving efficiency, customer service and resilience.

We encouraged them to look well beyond the next five years to meet the needs of future customers – and to protect and improve the natural environment.

Delivering to a higher standard

Companies submitted their business plans to us in September 2018, based on the methodology we set out in December 2017.

Three companies – Severn Trent Water, South West Water and United Utilities – submitted plans that set a new standard for the sector. Other than some limited interventions, these plans were ready to implement, so we awarded these companies with ‘fast-track’ status. Not only will they receive their draft determinations from us earlier than other companies – they will also receive financial and reputational benefits.

Other companies, whose original plans required more significant interventions, submitted revised plans to us on 1 April 2019. We will publish their draft determinations on 18 July 2019.
