Back in 2003 I was in the process of moving, just a mile away from a large semi, Edwardian five bedroomed house, to a terraced 3-bed 1930's house. The one I was moving from had been my family house, but several years earlier I had a water meter installed.
I was horrified to see that the water rates at the house I was moving into (about half the size of the one I was moving out of), was more than double what I was paying in the house I was leaving.
The vey first thing I did once moved, was to apply for a water meter.
In my current flat in a block of 25 with around 38 people living here, we include all water costs in with the service charge.
It does surprise me that the South West of England has such high water charges (as opposed to London), when there is so much water everywhere here.
