Seriously, £40 an hour for s plumber or other highly skilled trades people is, well, Luxury
£40 an hour, roughly £1,600 a week, approximately £77,000 a year (I assume a 46 week year, 4 weeks holiday and 2 weeks to cover illness, waiting in for gasmen, dentist etc).
From £77,000 taake the cost of buying and paying for a van, and all the running cost, plus tools and all sorts of insurance from van to public liability, health protection, professional fees etc. Say, net £50,000.
The median salary (that is a salary where half the population earn more and half earn less) is about ££36,700. For a highly skilled tradesman, who has done an apprenticeship and needs to keep up to date and often work in uncomfortable and inconvenient places, that seems reasonable.
