‘No difference’ in water usage following launch of Affinity’s rising block tariff

There has so far been no difference in water usage among customers participating in the sector’s first rising block tariff trial, Affinity Water has admitted. Launched last year, the WaterSave Tariff trial is designed to be a fairer, more affordable way for customers to pay for their clean water supply that’s also better for the environment. However, Martin Hall, the company’s head of economic regulation, told Utility Week it is not seeing different water use at the aggregate level across the trial and control groups.
