Under 10 employees

SiteGround

19.9% of band

Under 10 employees is the largest band, with 18,060 companies and SiteGround leading at 19.9%. Small B2B firms dominate here, with general hosting, managed WordPress, storage, and control-panel systems all present.

10–50 employees

SiteGround

23.4% of band

10–50 employees covers 8,073 companies, where SiteGround has the highest share at 23.4%. The band is still SME-weighted, but cloud platforms and managed hosting systems sit closer to mainstream business infrastructure needs.

How Hosting & PaaS usage is detected

Methodology

Company data

Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.

Detection

Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.

Freshness

Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.

Frequently asked questions

What is the most-used Hosting & PaaS among UK B2B companies?
SiteGround is the most-detected Hosting & PaaS among UK B2B companies, with 21% share (5,725 of 27,290 companies with a detectable system), ahead of Amazon Web Services (13.8%) and WP Engine (12.8%).
How many UK B2B companies have a detectable Hosting & PaaS?
27,290 of 112,345 actively-trading UK B2B companies (24.3%) have a Hosting & PaaS detectable from their public website. The remainder either run systems with no public web footprint or none at all, so detected share figures are a conservative floor.
What is a Hosting & PaaS?
A Hosting & PaaS system provides the infrastructure layer used to serve websites, applications, storage, databases, or managed web environments for UK B2B companies. It gives internal teams and external agencies a place to deploy and operate digital services without owning the underlying servers.
How is Hosting & PaaS usage detected?
Firmbase crawls the public website of every actively-trading company in this scope and fingerprints the technologies present — scripts, widgets, booking and checkout flows. A company is attributed to a system when that system's signatures are found; systems with no public web footprint are not attributable, which is why every share figure on this page means share of companies with a detectable system.
Which has more UK B2B companies, SiteGround or Amazon Web Services?
SiteGround: 5,725 detected companies versus 3,756 for Amazon Web Services, of the 27,290 UK B2B companies with a detectable Hosting & PaaS.
