We want to see if there’s a fairer, more affordable way for our customers to pay for their clean water supply that’s also better for the environment.
That’s why we’re the first water company in England to trial a new way of charging customers based on how much water they use. Customers on the WaterSave Tariff are charged based on what we call a rising block tariff, where the price of water increases the more that’s used, starting with a free allocation of water. We expect that 2 out of every 3 households will have lower bills on the WaterSave Tariff.
The trial started on 1st October 2023 and will last for 2 years until 30th September 2025. Around 1,500 customers who live in the Stevenage postcode area SG1 and have a water meter that we can read automatically, have been selected for the trial.
The trial only applies to customers’ clean water supply and won’t change their tariff for wastewater (sewerage) services.

Here’s how the tariff trial works:
Block 1: FREE
The first 30,000 litres of water used each year is free.
Block 2: £1.51
The next 215,000 litres used each year will cost £1.51 for every 1,000 litres used.
Block 3: £4
Then each 1,000 litres used over 245,000 litres each year will cost £4.
