I'm not sure if what you have advised is what the builder is proposing to do
Would the £380 be reasonable only if the builder does it on the way you have suggested ( plus the cleaning of the guttering and replacements of all the union joins ) ?
Put it this way, Baz.
If it's a biggish building firm, then it's probably what they would charge.
I still say that a handyman should be around £180-200 for a day's work. Plus the other £80 for materials assuming that ladder access is good.
It would have to be someone who knows what they're doing though.
It's always a problem for householders, until they latch on to a reliable tradesman.
Say it takes a day for one, and no materials. That makes roughly £380 x 5 = £1900 a week, i.e. £7.6k a month. Deduct tax, materials, insurance, travel and so on, and it doesn't sound so much. Plus, I doubt if he'd work without a mate and it might take more than a day.
Baz, despite what people think, it's perfectly legal to be paid in cash.
It's legal tender.
It's not your responsibility as to what he does regarding how, or if he accounts for it. As self-employed, he should declare it on his returns as "earnings".
One proviso..... don't ask him about it. If he tells you it's going to be spent without declaring it (black economy), then technically you are conspiring to defraud the Revenue.
Pretty remote of course, but you never know.
Just consider the reduced price as a discount.
...................... again, technically, if he's VAT registered and you know that, then you really are conspiring to defraud if he is not charging you VAT.
I know that all sounds a bit heavy, but this is a public forum
The downside to cash payment at a discount is that he may not provide a receipt or any form of proof that he has done the work. Difficult to get mistakes put right if he can deny he did the work.
