I had to go and give a quote today for a 4 bedroomed detatched house, both internals and externals. Some of the windows are a little awkward as the house is on a slope. Their previous window cleaner hadnt been since christmas (they have no idea whats happened to him) so they are looking for a new one. I quoted £46.00. They were a little shocked and told me the previous cleaner charged them £25.00. They reluctantly accepted my quote even though I suggested that they might want to get another quote. I came away feeling quite guilty. I cannot believe the previous bloke was doing the house for so little. Prices certainly vary locally as well as nationally.
