Tosh - I agree, a more difficult job will cost more, but plenty of guys on here charge more because they reckon the homeowner is a soft touch, or they have loads of money.
I'm afraid I fall into that category; if they look rich; and I've been asked to quote on recommendation, I'll stick in a good price; higher (given the amount of time taken) than if I was quoting for a commercial unit or a semi-detached house. I normally get it too, because the customer feels safe that I'm not going to 'rob them' and do a top job, since I haven't stolen from their equally affluent friend; and they're happy with their window cleaning service we provide; and of course, for over-priced customers, you will go that extra-mile!
Matt (of the DIY forum) has a name for this, he calls this the 'rich tax'.
Anyway, I don't feel bad about it. Why should I? I do one house with electronic gates, stables, a big indoor swimming pool, under floor heating, granite worktops, fish pond
s filled with Japanese Coy;
and the owner asks me for an invoice without my address on it! Why? Because he puts my cleaning bill through his books as if I'm cleaning his company offices, which is in another part of the country.So he's happy to fiddle his taxes for the small sum I charge him, I'm happy to charge him well for the relatively small amount of work I do for him.
Normally it's the working class's that have the privilege of paying more for services and getting less.
If they're rich, charge them well, especially if they find you on reccomendation.
