Contact Form 7 leads every size band, although its share falls as headcount rises: 62.3% in Under 10 employees, 57.5% in 10–50 employees and 51.3% in Over 50 employees. That pattern points to heavier fragmentation among larger B2B companies rather than a different outright leader.
The next tier is much smaller. Ninja Forms has 4.4% (1,317), WPForms 4.0% (1,209), Jotform 2.7% (802), Fluent Forms 2.1% (637), Typeform 2.0% (615) and Google Forms 1.1% (343), while 15 further systems cover 1,152 companies.

Under 10 employees
62.3% of band
The largest band contains 19,734 companies, and Contact Form 7 leads with 62.3%. The rest is split across WordPress form plug-ins and hosted form tools rather than a single close rival.
10–50 employees
57.5% of band
This band has 9,195 companies, with Contact Form 7 still ahead on 57.5%. Competition below that level is spread across smaller-share systems serving B2B sites with enquiry, quote and content-download forms.
Over 50 employees
51.3% of band
The over-50 band is smaller at 1,255 companies, and Contact Form 7 leads with 51.3%. Its lower share leaves more room for Gravity Forms, Typeform, Google Forms and other systems among larger B2B organisations.
How Form builder usage is detected
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.
