Anyone do this? Do you give a percentage, or what? My bathroom fitter has done a pretty decent job for me. Taken a little longer than expected, for both of us, but happy with his work and although he said the bill will still be what he quoted, he picked up wee bits and bobs and done some work probably wasn't factored in.
My quote was £1600 including a decent amount of tiling, although not full room, if that's helps.
You can sure bet if you do tip him and wanted to use him again he would do another great job and would make time for your job. I don't think it hurts to tip if you are exceptionally happy with something.
London has a bonus culture. If bankers are given huge bonus' I can't see why a tradesman should not, when he does a job well and provides good value.
Strangely though it is often the opposite. My general builder finds that those with the most negotiate hardest as if they need to "win" a negotiation. Hard negotiations are not his strength, so he tend just to work for people he knows and trusts.
Rosy, its sort of the same. I am happy to pay a bonus for a job well done, so I do. Often in the form of telling the tradesman to invoice for more than the quote. One trade will know other trades, so I can usually get a recommendation for other people when I need them. I could not have manged rental properties in London for as long as I have without a good support network. I have done well. I can't see why my builder should not get some benefit.
My husband is a plumber, he used to fit bathrooms but only fits boilers now. He is always getting tipped, he's had as much as £150 tip after a bathroom re-fit, his customers are always really happy with his work and realise that they've had an excellent job and they've saved a small fortune compared to the other quotes. £1600 is very reasonable for a new bathroom!
