Our plans for 2025-2030

Here you’ll find everything you need to know about our plans for 2025 and the next 5 years. Our plan has been built to deliver our vision: a thriving Yorkshire, right for customers, right for the environment.

A thriving Yorkshire.
Right for customers.
Right for the environment.

All water companies must produce business plans every five years. The business plans set out what water companies intend to deliver for customers and the environment. These plans must follow a specific process and then be submitted to Ofwat – the water industry’s economic regulator. Ofwat will assess the plans and make decisions about the amount of revenue we can recover from customers through their bills that can be spent to deliver the plans.

We look beyond five years to ensure that we’re making good decisions for our customers and the environment – now and in the future.

This is our business plan for the period 2025 to 2030 which forms the first five years of our 25-year Long-Term Delivery Strategy.

Our vision is to create a thriving Yorkshire, right for customers and right for the environment. This means achieving the following outcomes:

 

 

Deliver safe, clean, great tasting water and ensure we can continue to meet water demand in future.

Provide a tailored, reliable service and make sure that we are easy to interact with, in whatever way our customers choose to get in touch.

Deliver value for money to our customers, keep bills as low as possible, and offer the right support to customers who struggle to pay.

Build and operate efficient, climate-resilient infrastructure to provide reliable services for our customers.

Reduce pollution and sewer flooding, improve river quality, and enhance biodiversity across the region.

Reduce carbon emissions towards net zero across our business and supply chain.

Our draft determination representation

Our £8.2bn plan represents the start of a once in several generations approach to increasing resilience in our clean water supply, so important given the variability of our climate and the challenges with population growth.

It supports the changes we want to make to waste water treatment and will be our biggest ever environmental investment, which includes re-prioritised spend on storm overflows and continued support for flood resilience schemes like our Living With Water project in Hull.

Consultation with our customers and stakeholders has shown the importance of both these issues and we have responded to Ofwat’s feedback refocussing our five-year plan for 2025-2030, allowing us to deliver what is right for our customers and the environment.    

We know we need to make sure there is a balance to ensure it’s affordable for customers, as well as not passing the bill onto future generations. To support those who are struggling to pay their bills, we’re proposing to increase the funding for our social tariff from £30m per year to £55m per year which will help us to support a further 65,000 customers.

Our Business Plan

Latest information on our PR24 business plan

Since submission of our PR24 business plan to Ofwat in October 2023, we have made changes to parts of our plan. These have been in response to requests from Ofwat or other regulators and to clarify some points in our original plan. The result of these changes to date is that Ofwat are now considering a PR24 business plan for Yorkshire Water that includes total expenditure of £7.6 billion (down from £7.8 billion in our October 2023 plan), and average annual customer bills of £569 by 2030 (down from £585 in our October 2023 plan). Ofwat's draft determinations will be based on this expenditure and these bills.

The reason for the change to our total expenditure for PR24 and associated average annual customer bills is largely a result of subsequent changes made to our draft Water Resource Management Plan and rephasing of our Environmental Programme (WINEP).
