You know my thoughts on the matter.
Water meters seem to be a problem to remove, which is why the presence of one can affect the value of your property if you have a family house rather than a flat. What annoys me is that without a meter, water is billed according to the rateable value of your home, not the number of people living there, or how many bedrooms you have. So, a small 2 bedroom flat in London pays as much as a 4 bedroom house filled with 2 adults and 4 kids in Wiltshire.
