Activities Of Head Offices

Details for Activities Of Head Offices

Companies selecting 70100 are generally saying that their commercial activity falls within activities of head offices. In plain English, it is likely to include specialist operators, service providers, trading companies, administrative businesses and organisations whose work fits this defined economic activity, with day-to-day activity often involving client delivery, supplier relationships, operational processes, contracts, staff time, equipment and sector-specific administration. As of June 2026, 70100 ranks 52nd out of 731 five-digit SIC codes, with 35,457 UK companies registered under it, making it a sizeable and established area of UK business activity.

Because a UK company may register up to four SIC codes at Companies House, a business can pair this activity with other relevant codes where its operations span several markets or revenue streams. The short official label is deliberately compact, so the real-world businesses behind it may describe themselves using broader phrases such as activities of head offices services, specialist activities of head offices providers, operators in related supply chains, or companies supporting customers who need this form of commercial activity. A company using this code might be newly incorporated, dormant, small and owner-managed, or part of a larger group, so the SIC entry should normally be read alongside accounts, confirmation statements, websites and other commercial signals.

The classification is especially valuable when comparing suppliers, prospecting for customers, segmenting a database, reviewing competition or checking how a company presents its principal line of business on the public record. For search and data work, the wording should be understood broadly: companies may use different everyday terms for the same activity, including trade names, sector jargon, abbreviated service descriptions and customer-facing language. The code therefore works best as a structured indicator of economic activity rather than a complete profile of the company, because many organisations evolve, add services or reorganise after incorporation.

Taken together with location, age, filing history and other SIC selections, this code can help build a more rounded view of the market in which the company appears to operate. Although the wording of modern SIC codes is contemporary, the UK has used Standard Industrial Classification since the 1940s; the Companies House register moved from 4-digit SIC 2003 to the present 5-digit SIC 2007 framework during 2008–2009, aligned to European NACE Rev. 2.
