Most areas I would agree with you but I have family on the hants/surrey border and know that they can charge what @cleaniac is stating.I don’t think it matters on area too much but more towards the type of work you are doing. Part of my round is out in the sticks cleaning large cottages, farms and and barn conversions etc and maybe getting one or two jobs per hour. Those prices range between £20-80 per property. On the other hand some of my other work is very compact doing small semis, terraces and fronts etc were I can do maybe 5-10 jobs per hour. On that basis @ £25 minimums I’d be averaging £200 an hour which on a domestic run I find very hard to believe. Maybe cleaniac could elaborate on what kind of work he does as his comment was very vague and could be very misleading to the op.
Unfortunately that is how it goes in an affluent southern county.
Better prices than london where my old round was.
