The five busiest post towns hold 49 per cent of them and London alone 44 per cent. Selling nationally, those towns are most of the market. Selling locally outside them, expect a small pool, so cover a county or a region rather than one town.
A worked example: 63110, registered office in London, incorporated in the last ninety days, from a pool of 21,172. Each lead you get arrives with a working website and a real email, and the director's name when the record has one. If we cannot complete one, you pay nothing.
