Order once, order right

The most expensive mistake on any project is running short and paying a second delivery charge, or badly over-ordering and paying to get rid of the surplus. These calculators use standard UK trade figures for densities, coverage and pack sizes so you can order with confidence. Every result is an estimate, so always add a little for wastage and check with your supplier.
