Our company sizes are based on the UK’s legislation definition on company sizes. We also have a category for no employees or turnover.
A given company must meet at least two of the above conditions to be categorised accordingly. For example, a medium company may have 20 employees (small), but has £20m in turnover (medium) and £10m in assets (medium).
A company must have a registered postcode to be categorised into a company size bracket.
