*Johnsons considers itself a top 100 UK accountancy firm. This view is based on the Accountancy Age 50+50 for 2024, where the firm was c.£36k short of number 100, and since publication, there have been significant mergers in the market, and Johnsons has itself grown organically, along with acquiring other firms. Its client base and its PIE audit license would lend support to our capabilities in this respect.
