Our business plan for the next five years (2025 - 2030)

We're proud to present our business plan for 2025–2030. What our customers want shapes what we do, and our business plan focuses on the next five years of that journey. It reflects new requirements from our regulators and the feedback we’ve had from our customers and our stakeholders. It’s helped drive the pace and scope of our plan and our long-term ambitions.

What is our purpose?

We’re focused on building our resilience and providing a long-term sustainable supply of high-quality water, while protecting our environment for our communities – now and in the future.

What is our aim?

Our aim is to provide efficient and affordable services, both now and in the long term.

Our long-term ambitions

These are focused on four key areas:

  • The Environment 
  • Resilience
  • Our customers
  • Our communities

Revised Business Plan for 2020 to 2025

After our Business Plan for 2020 to 2025 was submitted to Ofwat in September 2018 after a review from Ofwat we received feedback from them in January 2019. We have carefully listened to Ofwat’s feedback and improved our September plan in a range of specific areas to deliver even more for our customers and communities.

We are going to do more for less, by:

  • Reducing the average household bill. We now plan to reduce our average bill by 1.6% in real terms by 2025 compared to an increase of 2.1% in our September Plan;
  • Stretching ourselves further through our commitments, including on leakage where we have increased our reduction target from 15% to 18.5% (equivalent to 30 Ml/d);
  • Adding additional commitments that are dedicated to supporting customers in vulnerable circumstances, and those who will benefit from our Priority Services Register.

All the detail is included in our Revised Plan below.
