Households in England and Wales are set to see their water bills rise by an average of 4.1 per cent this year.With this increase, which includes inflation, the average annual bill for kitchen user will rise to 342, according to the Consumer Council for Water.Dame Yve Buckland, Chair of the Consumer Council for Water, said Any price increase will be a concern for customers in the current economic climate and we recognise that many customers may struggle to keep up with these bill rises.In 2004 Defra predicted that more than one in ten customers would struggle to afford the prices being announced today because, for these households, water bills would make up more than three per cent of income after tax.In light of these rising costs, kitchen users would be wise to invest in some appliances that could lower their consumption and, as a result, their expenditure.The hot water filter tap from leading manufacture In-Sink-Erator offers steaming hot water on demand potentially eliminating the need for a kettle and provides freshly-filtered tap water, reducing the need for separate filter jugs.
