Each year we set our charges according to price limits that are determined by our regulator Ofwat every five years. Your supply is either unmetered or metered and this affects the way we charge for your water supply:
Unmetered
We use the rateable value of your property and calculate the cost for the year in advance.
Metered
We read your meter twice a year and you pay for the water you use. All domestic customers' can ask for a meter to be installed free of charge. For those who opt for a meter, we offer a money back guarantee on your meter; customers are entitled to a refund of their bills if their metered bills are higher than their unmetered bills.
