Fastest-growing companies in the UK
These are the fastest-growing independent companies in the UK by year-on-year revenue growth, taken straight from their filed accounts. To keep the list to real trading growth, every company has at least £1m revenue, five or more employees and a profit, and is not part of a larger group. Jumps of 5x or more in a single year, which are usually one-off sales rather than growth, are excluded.
