Under 10 employees

SiteGround

29.6% of band

This is the largest band, with 710 companies using a visible Hosting & PaaS system. SiteGround leads with 29.6%, while the rest of the market is spread across low-headcount accountancy practices and smaller specialist firms.

10–50 employees

SiteGround

34.7% of band

The 10–50 employee band contains 285 companies and remains weighted towards SiteGround, which leads with 34.7%. Competition here also includes systems used by somewhat larger practices with more formal web and hosting requirements.

Over 50 employees

WP Engine

27.3% of band

Only 11 companies sit in the over 50 employee band, so shares are sensitive to small count changes. WP Engine leads this band with 27.3%, ahead of a thinner mix of other Hosting & PaaS systems.

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.

What is a Hosting & PaaS?

A Hosting & PaaS system provides the infrastructure used to run websites, web applications and hosted workloads. For UK accounting companies, it supports client-facing sites, internal web services and the hosting layer behind digital accountancy workflows.

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 accounting companies, SiteGround or WP Engine?

SiteGround: 310 detected companies versus 117 for WP Engine, of the 1,006 UK accounting companies with a detectable Hosting & PaaS.

What is the best Hosting & PaaS for UK accounting companies?

Usage shares are published as observations rather than product recommendations, so “best” is treated as market fit by segment rather than a ranked verdict.
