Preparing for bill increases

Find out why water bills are increasing, how much they could go up and how we can help if you're struggling to pay.


We are investing more than ever in our services. To help us deliver improvements, our charges increased as of 1 April 2024.

We are currently going through the process to set next year’s charges. Based on latest information, we expect that charges will increase again from 1 April 2025, but final charges are still to be confirmed.

We know that price rises are always unwelcome, so we can help with your water bill if you are struggling to pay.

Why are bills set to increase?

We are seeking to deliver a massively ambitious set of outcomes. Our plan for 2025-2030 proposes a record £3.65 billion of new investment across our water and sewerage networks. This is more than double what we have invested over the last five years, and includes:

  • £1.13 billion to improve river and coastal water quality by upgrading our treatment sites and removing 1,550 tonnes of nutrients in our waterways.
  • £445 million to reduce the operation of storm overflows. This is more than double the £3m a month we are currently spending.
  • Innovative use of sewer monitors to predict problems in the network, real-time water quality monitoring for bathing waters and low carbon nature-based treatment solutions.
  • £940 million on asset resilience to ensure our network continues to be fit for purpose in the longer term.

This new investment will create an additional 700 jobs at Wessex Water, with thousands more in the supply chain.

Much of this investment is required to meet new standards and obligations that are coming into force, as well as more stretching targets that regulators are setting for the water industry from 2025 onwards. It also reflects customers’ and stakeholders’ views about what improvements should be prioritised.

Delivering these improvements will affect customers’ bills. But our plan does not include any investment that has already been funded, and we are not asking customers to pay twice.

How much could bills go up from 1 April 2025?

Over the last year, the regulator Ofwat has been reviewing our 2025-2030 plan and the proposed investment programme contained within it. Ofwat recently issued its final decision for the 2025-2030 period. We are currently reviewing what this means for next year’s charges.

However, based on Ofwat’s draft decision (published earlier this year), a two-person household with a water meter would see an increase of around £4 a month next year, or around £5 a month for those not on a meter.

These figures apply to customers who receive both water and sewerage services from us. They may vary slightly for customers who receive one service from us and another service from a different water company.

Our full charges for next year will be confirmed by the start of February 2025, taking account of Ofwat’s final decisions on our investment plan.

What if you are struggling to pay your bill?

We understand for some households an increase in your water bill could be hard to afford. If you are struggling, please don’t worry, we can help you with your bill.

You might also find you could make savings on your bill by having a meter fitted.
