But the reason i think you will find there is rule 9 is becuse some one will ask:
I want an extra radiator how much will this cost?
or
I wnat an extra socket how much will this cost?
the problem is, as forum rule 9 points out how can any one even give a gusetimate without seeing the job?
it may be they live on the 12th floor of a block of flats with no parking and want a job doing, and more often than not there is always more involved in the job that what the person asking is telling, be it intentional or not.
yes "the bloke form down the pub will do it for £50" but is he doing it right and will he be able to issue the relevant paperwork? (i think not) hence forum rule 9
this being a typcal example (yes it s old, but its typical.
also put the shoe on the other foot
x asks how much for zxc some one says £708, person likes it some one does job and invoices for £908, "but on diy not they said its only £708"
Stuffed arent you.
