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 IT services companies?
Amazon Web Services is the most-detected Hosting & PaaS among UK IT services companies, with 15.9% share (281 of 1,765 companies with a detectable system), ahead of SiteGround (14.8%) and WP Engine (13.1%).
How many UK IT services companies have a detectable Hosting & PaaS?
1,765 of 121,886 actively-trading UK IT services companies (1.4%) 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 hosted infrastructure, platform layer or managed environment used to run websites, applications and related services. For UK IT services companies, it typically supports client delivery, internal tools, web hosting, application deployment or storage rather than acting as a back-office finance or CRM system.
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 IT services companies, Amazon Web Services or SiteGround?
Amazon Web Services: 281 detected companies versus 261 for SiteGround, of the 1,765 UK IT services companies with a detectable Hosting & PaaS.
What is the best Hosting & PaaS for UK IT services companies?
This page reports observed usage rather than recommendations, so there is no single “best” Hosting & PaaS system implied. Amazon Web Services has the largest detected share overall at 15.9% (281) and also leads Under 10 employees at 15.1% and Over 50 employees at 31.3%, while SiteGround leads 10–50 employees at 17.5%. Overall detected usage spans 33 systems across 1,765 companies, with 25 further systems covering 489 companies.
