The entitlement to a particular company size regime is determined by reference to criteria set out in CA 2006. Qualitative factors are used to establish whether a company is excluded from a regime because of its nature. For example, public companies and certain financial services companies cannot qualify as micro-entities, small, or medium-sized companies. There are also restrictions in certain group situations, for example, when a company is part of an ‘ineligible group’.

A company will additionally need to assess whether it qualifies for a regime by meeting the relevant size thresholds for turnover, balance sheet total (meaning the total of the fixed and current assets) and the average number of employees.

In March 2024, the UK government at the time announced plans to raise the monetary company size thresholds, with effect from 1 October 2024. Following the UK’s general election in July 2024 and the formation of a new government, it is not yet clear if, or when, these plans will proceed.
