IT companies registered in Belfast, not yet checked
Registered under SIC 62030, computer facilities management, the closest code the UK has to managed IT, with the facts the register holds. Not checked means we have not yet confirmed a website for the company that shows its number and describes managed services: it is not a judgement about the business. Larger filing categories first, then the longest-established: a filing order, not a ranking.

What this page is, and is not
Who is on it
Checked companies come first: the registered number is displayed on the company's own website, confirmed on a date we publish, and that website describes managed services in two or more independent ways. Then every other company registered here under SIC 62030, computer facilities management, the closest code the UK has to managed IT, unless we read its website and it described something else. All of it is facts from the register or about a public page on a date, not a judgement about any business.
Who is not, and why
17 companies are on the register in Belfast but left off this page: larger firms listed by filing size under the broad IT codes, with no evidence from their own site that they provide managed services, and companies whose own website, read on a recorded date, describes something else. They stay on the register. See every company registered in Belfast.
No score, and no stars
The register carries no ratings and no rankings. A Featured entry is a paid position and says so on the row. Otherwise, if two companies appear in a different order it is because one has confirmed its entry and the other has not, or because of the alphabet.
The location is approximate
Registered office town and postcode district only. A company can be registered in one town and work from another, and many are registered at a director's home.
