There is help for certain metered customers who need to use extra water because of a medical condition.
The vulnerable groups scheme, called WaterSure, allows certain customers in England and Wales on a metered water charge to use extra water without worrying about receiving a high bill.
To be eligible, customers must have a water meter and be receiving income-related benefits. They must also have either three or more children under 19 at home or a medical condition that requires extra water.
Examples of medical conditions include: weeping skin diseases (such as psoriasis), Chrohn’s disease or ulcerative colitis.
Customers who meet the criteria can have their water bill capped at the amount of the average household bill for their water company.
