Security Dealing On Own Account

Details for Security Dealing On Own Account

The wider SIC framework has been part of UK business statistics since the 1940s, and Companies House previously used the older 4-digit SIC 2003 codes before moving during 2008–2009 to the present 5-digit SIC 2007 structure, which is aligned with European NACE Rev. 2 standards. This classification covers companies whose practical work is best described by the official label security dealing on own account.

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, 64991 ranks 193rd out of 731 five-digit SIC codes, with 6,638 UK companies registered under it, making it a substantial sector with a strong presence among incorporated businesses. Companies are not limited to a single activity description: Companies House allows up to four SIC codes, so mixed businesses can show this work alongside complementary trading, advisory, production or support activities.

The short official label is deliberately compact, so the real-world businesses behind it may describe themselves using broader phrases such as security dealing on own account services, specialist security dealing on own account providers, operators in related supply chains, or companies supporting customers who need this form of commercial activity. 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.
