There is a misconception on here that "areas" are different. And while I accept that some grimethorpe wasteland or industry bereft welsh sinkhole with no work is going to be a bit more depressed than sunny southern computer valley I would suggest that it's
people that are different.
Someone in say Cheshire, Somerset, Midlothian or Essex will cheerfully pay £25 every month for a 4 bed detached to a reliable, honest personable windie if it means they can leave their precious home in their trusted care while they work hard, play hard and enjoy life. If someone went in at a tenner or £12.50 they wouldn't give them time of day - they realise that that windie will possibly not be reliable or insured or do a good job as he will cut corners.
Another will scrimp about and jump at the low price until they learn that to get a reliable windie you have to pay the going rate. Or they won't learn. And the windies that clean for them typically scratch about getting the poor customers.
The ones you lot need to worry about are the ones like me - I charge £20 for a 4 bed detached - I have no worry from undercutters and get people come up and ask for my services because I am as reliable and trustworthy as the day is long and do a good job every time. (except the rare time when I don't and then I'll put it right at no charge)

Some people value themselves so low and are so scared of competition they choose to work for low prices rather than they are forced to.
John Ruskin said "it's better to pay a little too much and get good service and work than too little and get rubbish, because then you'll pay twice to get the job done." (Gold abridged paraphrase version)
