Electrical Installation

Details for Electrical Installation

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 electrical installation.

In plain English, it is likely to include contractors, trades, builders, installers, maintenance firms, developers and specialist construction service providers, with day-to-day activity often involving site work, project delivery, materials, labour, repairs, installations and compliance with building requirements. As of June 2026, 43210 ranks 25th out of 731 five-digit SIC codes, with 68,294 UK companies registered under it, making it among the highest-volume classifications on the UK register. 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 electrical installation services, specialist electrical installation 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.
