most good kitchen fitters are carpenters and good bathroom fitters are plumbers.
A man after my own heart---unfortunately everyone I work for wants to pay me in groats & a pint of mead an hour
I am doing some plumbing for a kitchen fitter tomorrow, he knows nothing about plumbing and would not have a clue about fitting a bathroom.
Forty years of fitting bathrooms/tiling/kitchens/heating and people still think I'm ripping them off for charging twenty five quid to change their mixer tap.
Educated guess, you work in Brighton & Hove, and for landlords.
