I just do it on a day rate plus materials..
no Travis Perkins near you Stef?, that's where I get my HB.I supply & fit Hardie 250 at £30 per board if its a smallish area (1/8m2) & drop that to £20 per board if its a good sized area.
Sounds expensive but in my area the only place you can purchase Hardie is Topps & we all know how much it costs in there.
