How the register formed
This counts companies that are active today, grouped by the year they were incorporated. It is a picture of who survived, not of who started. Incorporations up to 1993 are shown as one bar holding 527 companies.
The oldest incorporation still on the register is from 1895, the newest from 2026, a span of 132 years. 22 per cent of the register is under three years old and 52 per cent is over ten. The weight of the register sits with companies that have been trading for a decade or more.
Where they are
Towns come from the registered office address, cut to the town and the postcode district. A registered office is where the paperwork goes, which is not always where the work happens.
LONDON holds more of the register than anywhere else, 2,697 companies and 33 per cent of the total. The ten largest towns hold 3,588 between them, 44 per cent of the total, spread across 1,089 recorded towns. 516 towns appear once. Every company counted here is registered in the United Kingdom.

Size, as far as filings show it
Companies House sorts filings into categories by threshold. The category says which set of rules a company files under. It is not a measure of quality and it is not a ranking.
- Files full accounts: 2,456, 30 per cent
- Files medium accounts: 152, 1.9 per cent
- Files small accounts: 4,278, 52 per cent
- No accounts filed yet: 1,325, 16 per cent
2,608 companies file above the small company thresholds, 32 per cent of the register. The rest sit within them.
Age and filing threshold move together
Companies filing full accounts have a median age of 19.3 years, against 10.9 years for those filing small accounts, a gap of 8.4 years. The full filers number 2,456, the small filers 4,278, so the comparison is between a small group and a large one. A threshold is crossed by growing, and growing takes time, so the direction is what you would expect; the size of the gap is the part worth citing.
How a company gets on to this register
Three routes, counted separately, because the route decides what the entry is evidence of.
5,330 companies were picked up by code alone, 65 per cent of the register. 2,521 were added from what they filed rather than from the code.
5,330 companies declare 62030, the facilities management code, which is 65 per cent of the register. The other 2,881 appear under a broader description only, 35 per cent of the register. That is the gap a search on the single code would miss. 4,572 companies declare more than one code, 56 per cent of the register.
| Code | Description | Companies | Share |
|---|---|---|---|
| 62030 | Computer facilities management | 5,330 | 65 per cent |
| 62020 | Information technology consultancy | 3,715 | 45 per cent |
| 62090 | Other information technology services | 3,451 | 42 per cent |
| 62012 | Business and domestic software development | 1,487 | 18 per cent |
| 63110 | Code not tracked by name | 736 | 9 per cent |
| 95110 | Repair of computers and peripheral equipment | 255 | 3.1 per cent |
| 63120 | Code not tracked by name | 224 | 2.7 per cent |
| 70229 | Code not tracked by name | 209 | 2.5 per cent |
Websites
822 entries carry a date on which the company's registered number was found on its own website, 10 per cent of the register.
What their own websites say
Companies on the register with a confirmed website have their homepage read against a fixed list of managed service terms. A site that uses terms from two or more different groups reads as a managed provider. This section counts how those providers describe themselves.
893 homepages were readable. 524 of them, 59 per cent, read as managed providers. Of those, 48 per cent mention Cyber Essentials or a virtual CISO, 52 per cent advertise a help desk or service desk, and 34 per cent talk about backup or continuity. 22 per cent offer Microsoft 365 support in so many words. Security operations, a SOC or managed detection and response, appears on 15 per cent.
The median provider homepage uses 3 of the ten groups.
| Mentions | Homepages | Share |
|---|---|---|
| Managed or outsourced IT | 447 | 85 per cent |
| Help desk or service desk | 273 | 52 per cent |
| Cyber Essentials or vCISO | 254 | 48 per cent |
| Backup and continuity | 178 | 34 per cent |
| Endpoint and patching | 147 | 28 per cent |
| 24/7 or remote monitoring | 128 | 24 per cent |
| Microsoft 365 support | 115 | 22 per cent |
| SOC or MDR | 80 | 15 per cent |
| A security vendor by name | 34 | 6.5 per cent |
| An RMM or PSA by name | 20 | 3.8 per cent |
How to read this
The shares are biased upward by construction: a site counts as a provider only because it already used two groups, so every group is likelier to appear here than across the trade as a whole. It is the homepage only, and only these terms; a provider that offers patching and says so on its services page is not counted as saying it. 9 sites returned almost no text and are left out rather than guessed at. Vendors are counted as a group and never by name, so this cannot be read as a table of suppliers.
What this counts, and what it does not
Survivors, not formations
Every figure here is drawn from companies active on the register at the retrieved date. A company incorporated in 2014 and dissolved in 2019 is absent. The year chart therefore shows how many companies from each year are still trading, which is a different number from how many were formed.
SIC codes are self-declared
A company picks its code at incorporation and rarely revisits it. Some managed providers sit under a broader code, and some companies under the managed IT code do something else entirely.
The accounts category is a threshold
It records which filing rules a company met at its last accounts. It is not turnover, headcount, quality or standing, and this page never treats it as any of those.
Coverage is the codes tracked
The pull covers the codes this register tracks, plus companies added on request. It is not every managed IT provider in Britain, and no claim is made that it is.
Town is the registered office
It is the address on the register, cut to the town. A company registered at its accountant's office in one town and working from another is counted in the first.
Exclusions

Using these figures
The numbers on this page may be quoted and the charts reproduced, with a link back. They are recomputed from the register on every build, so a figure cited today may differ from the same figure next month; the retrieved date above says which snapshot you are reading.
