Determining the size of a company

Published: 13 Sep 2022 Updated: Yesterday at 11: 44 AM GMT Update History

When preparing and filing accounts and reports in accordance with the Companies Act 2006 (CA 2006), there are four sizes of company to consider - micro-entity, small, medium-sized and large.

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. The company size limits are met for a financial year if any two of the following three thresholds are met:


Micro
Small
Medium
Turnover not more than
£632,000
£10.2 million
£36.0 million
Balance sheet total not more than
£316,000
£5.1 million
£18.0 million
Monthly average number of employees not more than
10 50 250
Upcoming changes to company size thresholds

From 6 April 2025, legislation will come into effect to increase company turnover and net assets thresholds by approximately 50%. This uplift in thresholds accounts for inflation since the previous thresholds were set and is also part of the government’s drive for more proportionate reporting. Companies able to move down a size category will be entitled to the accompanying reduction in reporting requirements.

Find out more about the context for these amendments in the following By All Accounts article (published in April 2024):

Large companies

Any companies that do not meet the criteria to be a micro-entity, or a small or medium-sized company, are large companies and are required to prepare and file full accounts.
