What Is a UK Micro-Entity Company?
A micro-entity is the smallest formal category of UK limited company under the Companies Act 2006. To qualify, a company must meet at least two of these three criteria: annual turnover not exceeding £632,000; balance sheet total not exceeding £316,000; average number of employees not exceeding 10.
Micro-entities benefit from simplified reporting requirements - they can file a minimal balance sheet at Companies House without disclosing a profit and loss account, which means their actual revenue and profitability are often not publicly available. This makes independent financial assessment of micro-entities more limited than for larger companies.
Approximate Revenue Range: Under £632,000
Because micro-entities must have turnover under £632,000 to qualify, the Companies House micro-entity accounts type is the most reliable public indicator that a company's annual revenue is below this threshold. This makes the micro-entity classification a useful proxy for finding genuinely small UK businesses, even when the exact turnover figure is not disclosed.
Who Targets Micro-Entity Companies?
- Accounting software providers - very small businesses are the core market for simple bookkeeping and cloud accounting tools
- Accountants and bookkeepers - sole practitioners and small accounting practices specialise in micro-entity clients
- Insurance brokers - micro-entities need basic business insurance but require simple, affordable products suited to their size
- Business banks and fintechs - challenger banks targeting small businesses often focus on micro-entity founders as their core demographic
- Sole trader conversion services - micro-entities that were previously sole traders are often still evaluating whether incorporation was the right choice
How Does the Micro-Entity Threshold Relate to VAT Registration?
The current VAT registration threshold is £90,000 in rolling 12-month turnover. A micro-entity with turnover between £90,000 and £632,000 may be VAT registered. A micro-entity below £90,000 may not be. The micro-entity classification tells you the company is small, but not whether it is VAT registered - those are separate thresholds governed by HMRC.
Frequently Asked Questions
How many UK micro-entity companies are registered at Companies House?
Around 5,000 active UK companies are currently registered with micro-entity accounts at Companies House. This figure represents companies that have filed their most recent annual accounts using the micro-entity simplified format. Many more companies may qualify as micro-entities but have not yet filed accounts or chose to file in a different format.
Does a micro-entity company have to disclose its turnover?
No. Micro-entities can file a simplified balance sheet without a profit and loss account, meaning their actual turnover is not publicly available. What you do know is that they qualify under the micro thresholds, which implies turnover below £632,000. This is in contrast to larger companies which must file more detailed financial information.
What is the difference between a micro-entity and a sole trader?
A sole trader is an individual trading in their own name - they are not a registered company at Companies House, have unlimited personal liability, and their business and personal finances are the same legal entity. A micro-entity is a registered limited company - it is a separate legal entity, provides limited liability protection to its directors and shareholders, and must file annual accounts and confirmation statements at Companies House.
Can a micro-entity company grow into a small or medium company?
Yes. If a company's turnover, assets, or employee count exceeds two of the three micro thresholds in two consecutive years, it must upgrade to small company accounts in subsequent years. NewcoHunter tracks these transitions - see the growing companies page for companies that have moved up from micro to small accounts.
Are micro-entity companies good B2B sales leads?
It depends on the product or service. For very low-cost tools and services (simple accounting software, basic business banking, entry-level insurance), micro-entities are the core market. For more expensive B2B products, micro-entities may not yet have the budget or operational complexity to need them. Filter by sector to find micro-entities in the industries most relevant to your offering.
