UK SIC 2007 · 62020
IT consultancy activities (SIC code 62020)
UK IT consultancies sit here. The code covers IT advice, integration, support, roll-outs, and managed services. It is separate from 62012 (building software) and 70229 (management consultancy). Solo IT contractors and managed service providers file it a lot.
This is the technology heartland of the UK register. IT consultancy, code 62020, is the single most common choice. Contractors and consultancies alike use it. Software development on 62012 and the broad 62090, other IT service activities, follow close behind. Games developers have their own code, 62011. Computer facilities management is 62030. Much of the division is one-person limited companies. Developers, architects and consultants contract through them. So the same code can describe a global consultancy and one person working through a personal service company. Keep that in mind when you segment.

Who prospects SIC 62020 companies
Contractor-heavy sectors reward specialists, and this division has plenty. Accountants built around IR35 and personal service company compliance work it daily. So do professional indemnity insurers and recruiters placing contract and permanent engineers. SaaS vendors selling developer tooling, cloud services and productivity software treat division 62 as their core market. A new incorporation often means a first contract starts within weeks. That is when insurance and accounting get bought. Growth between filed accounts separates scaling agencies from steady contractors. Those growing firms are the ones ready for hiring, office space and larger software deals.

SIC 62020 is a five-digit code, and the digits are not arbitrary. The first two, 62, are the division, computer programming, consultancy and related activities. Add the third and you have group 620; the fourth narrows it to a class, and the fifth to the subclass, which is the level Companies House actually asks a company to pick. The whole division sits under section J, information and communication, the broadest tier there is. Reading a code left to right therefore goes from a whole sector down to one activity.
A company chooses its own codes when it incorporates and can change them on any confirmation statement. It may list up to four, and Companies House does not check whether they are right. That is why 62020 is worth reading as a claim the company made about itself rather than as a verified fact, and why the first-position and any-position counts above differ.
Measured on the August 2026 register, the busiest registered-office post towns for 62020 are London (47,425), Manchester (2,562), Birmingham (1,995), Reading (1,813), Leeds (1,633). Those are registered-office locations, which is where the paperwork sits rather than necessarily where the work happens, so treat them as where to start looking rather than as a service area.
Using SIC 62020 as a filter
160,697 companies is 3.1 per cent of the 5,190,464 active companies on the UK register, and ranks 62020 most used of the 5 codes we track in division 62. That is the pool before any filter. Whether it is a big market for you depends on what you sell, but it is the number every other filter on this page cuts down from.
118,525 companies put 62020 first and a further 42,172, 26 per cent, list it in one of their other three SIC slots. That gap is the difference between a tight list and a broad one. First-code-only is the safer filter when you are writing to them; matching any position is worth it when you need the volume.
These companies are spread out. London is the largest single cluster at 30 per cent and the top five post towns together hold only 34 per cent, so the remaining 66 per cent sits across the rest of the country. A regional filter narrows this list without gutting it, which makes it a reasonable code to work territory by territory.
In practice the code on its own is rarely the whole filter. Pair 62020 with an incorporation date to catch companies in their first months, when they are still choosing suppliers, or with a filing deadline to reach them while the year end is on their mind. A worked example for this code: 62020, registered office in London, incorporated in the last ninety days, which turns a 160,697 company pool into a list you can write to in an afternoon. Add the poor-website filter if what you sell is a website, or a recent change of officer if you sell to whoever just took the job. Every company you pull carries the Companies House record, the director's name, a verified website and a verified email, and the ones we cannot complete are not charged.

About SIC 62020
How do I tell SIC 62020 firms apart from 62012?
62020 sells services: advice, integration, roll-outs. 62012 sells product: software built for clients or sold as a product. Plenty of firms file both. The 'what we do' page on their website settles it fastest.
Do sole-director IT contractors use SIC 62020?
Often, yes. IR35 reform pushed many independent contractors to set up a ltd company. 62020 is the code most of them choose. Filter for one director plus 62020 to pull them out.
