This is the size of the market, not the size of our dataset.

What counts as IT and software

The industry covers divisions 62 (computer programming, consultancy and related activities) and 63 (information service activities) of UK SIC 2007. Publishing, broadcasting and telecoms belong to the same section J but are not included; this also leaves out publishers of ready-made software (58.29) and of computer games (58.21).

The UK splits class 62.01 into games and leisure software development (62.01/1) and business and domestic software development (62.01/2). Division 62 also includes one-person companies through which IT contractors sell their services.

Disclosure rules instead of a sector register

For IT firms, the useful public sources are the ones that apply to every business: what a website must disclose, and what Companies House holds.

Website information
Anyone providing an online service must make available their name, geographic address and contact details including an email address, plus their register entry and VAT number where applicable (Electronic Commerce (EC Directive) Regulations 2002, reg. 6). For IT firms, the contact or legal page is therefore the most important source.
Company details on websites
A company must also show its registered number, registered office address and the part of the UK in which it is registered on its websites (Trading Disclosures Regulations 2015, reg. 25). This is what links a website to a Companies House number.
Companies House
Limited companies are on the register with up to four SIC codes, which the company chooses itself; the free snapshot holds no phone numbers, emails or websites. Freelancers trading as sole traders are not registered at Companies House.

Not in the export

  • technology stack, partner status and certifications
  • number of developers and turnover
  • names of directors and IT leads
  • clients and reference projects
  • job vacancies and hiring plans

These 15 columns are included.

Development, consulting or operations: what you are after

Classes 62.01 and 62.02 overlap heavily in practice. A systems integrator that writes code and advises is filed under its main focus, and at Companies House the SIC code is the company’s own choice. For a broad target group, the whole of division 62 is the better choice.

If you only want firms with offices and staff, make the website a required field and, for records already matched with Companies House, check the legal form. That helps to separate software houses and MSPs from one-person contractor companies.

An email address on an IT firm’s website meets an information duty; it is not consent. A B2B email to a limited company is still allowed without prior consent if you identify yourself and give a valid opt-out address (PECR reg. 23); to a sole-trader freelancer only with consent or under the soft opt-in.

Questions

IT and software: frequently asked questions

Yes, if they appear in a source with a business address. A contractor’s limited company is on the Companies House register; a sole-trader freelancer is not. If you only want firms with offices, filter by website and legal form.

No. Publishing of ready-made software is 58.29, telecommunications is division 61; neither is part of this industry. Both can be added to a request.

The published address is not consent. For a limited company or LLP you do not need consent under PECR, but you must identify yourself and offer an opt-out; for a sole trader you need consent or a soft opt-in. If the address names a person, UK GDPR applies too. Details: PECR rules for B2B email and calls.
