The next tier is narrower: W3 Total Cache has 7.7% (859 companies), WP Super Cache 5.7% (634), Redis Object Cache 4.8% (532), WP-Optimize 4.7% (522), WP Fastest Cache 4.5% (506) and NitroPack 1.9% (215). Four further systems cover 301 companies, so the long tail is present but small beside the two largest systems.
LiteSpeed Cache has the largest share in every employee band: 46.8% among 7,106 companies under 10 employees, 46.2% among 3,599 companies with 10–50 employees, and 38.4% among 479 companies over 50 employees. Its lower share in the over-50 band points to a more mixed larger-employer end, although the segment is much smaller.

Under 10 employees
46.8% of band
The under-10 band contains 7,106 companies and is almost half LiteSpeed Cache, at 46.8%. WP Rocket and the mid-share group, including W3 Total Cache, WP Super Cache, Redis Object Cache, WP-Optimize and WP Fastest Cache, compete for the remainder.
10–50 employees
46.2% of band
The 10–50 employee band contains 3,599 companies, with LiteSpeed Cache on 46.2%. WP Rocket remains the main counterweight by overall share, while W3 Total Cache, WP Super Cache, Redis Object Cache, WP-Optimize and WP Fastest Cache sit in the smaller-cache tier.
Over 50 employees
38.4% of band
The over-50 band is small, with 479 companies, and LiteSpeed Cache has a lower but still largest share at 38.4%. That leaves more room for WP Rocket and the other named systems than in the two smaller employee bands.
How Caching 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.
