You deliver to a merchant in May, timber to the yard or cable to the counter, and bill it on 30-day terms. These are nine of the biggest builders’ merchants and trade suppliers by money paid to suppliers in their latest reports to the government, one company per group: building supplies, plumbing and heating, electrical wholesale and joinery. Each dot is your 6 May bill, paid on that company’s own average.
