It's not just plumbing and gas work though. You say they will pay hundreds for solicitors but people would still phone around and get the cheapest. It's just the way it is, thing to do is give them your price if they query it then dont worry just move on to the next customer.
We live in an age where large companies RIP off loyalty so people have no loyalty anymore. Unfortunately it's just the way now nothings going to change that so dont lose sleep over it. If they pay someone £20 cash and then have pay hundreds further down the line then it's their own fault, just be nice and say sorry I cant help you then when you see their house is now a pile of rubble laugh and carry on.
