How the quantities are worked out
Each material is counted in the units merchants sell it in, with normal waste allowed, so you can order straight from the list. Labour is the on-site time for one competent tradesperson, including setting up, testing and clearing up. Change the measurements and the whole quote moves with them; that's what Quotable does for you on every job, with each material priced live at UK merchants.
