Yorkshire Water said it could not provide a figure for how much of a discount WaterSupport customers will get on their bills next financial year as it is applied based on individual household's circumstances.
Every water company has a social tariff scheme which can help reduce your bills if you're on a low income and the CCW is calling on customers to take advantage before bills rise in April.
Angie Markham-Nock, affordability strategy manager at Yorkshire Water, said: “The next five years are really important for us, for the environment, and for our customers, as we deliver an £8.3bn investment programme to help us meet expectations and regulatory requirements.
The firm is run by Pennon, which also bought Sutton and East Surrey Water, but customers here will see their bills reduced by 3% over the next five years.
If you're on a water meter but find it hard to save water as you have a large family or water-dependent medical condition, you may be able to cap your bills through the WaterSure scheme.
