UK SIC 2007 · 62012
Covers UK software developers, bespoke development, SaaS products, internal tooling, and contract development. The canonical UK 'tech company' SIC code. Distinct from 62020 (IT consultancy) and 63110 (data processing).
This is the UK register's technology heartland. IT consultancy under 62020 is the single most common choice, heavily used by contractors and consultancies alike, with software development on 62012 and the broad 62090, other IT service activities, close behind. Games developers have a dedicated code at 62011, and 62030 covers computer facilities management. Much of the division consists of one-person limited companies through which developers, architects and consultants contract, so the same codes describe both a global consultancy and an individual working through a personal service company, which is worth remembering when segmenting.
Contractor-heavy sectors reward specialists, and division 62 has plenty: accountants built around IR35 and personal service company compliance, professional indemnity insurers, and recruiters placing contract and permanent engineers all prospect these codes daily. SaaS vendors selling developer tooling, cloud services and productivity software treat the division as their core addressable market. New incorporations frequently mark a first contract starting within weeks, the moment insurance and accounting get bought, while growth between filed accounts distinguishes scaling agencies from steady-state contractors and flags candidates for hiring, office space and larger software deals.
