B2B Companies Using ThemeIsle in the UK: 145 Active Firms (2026)
B2B firms running a packaged website stack sell products or services to other organisations across the UK.
For business-to-business suppliers, this theme-led stack usually belongs to the marketing and sales operations layer rather than core product delivery. Running it tends to signal an owned inbound channel, a modest website budget and a lean team that needs brochure pages, enquiry capture and proof points to work without a large digital department. Engagements are more often agency builds, maintenance retainers or incremental site upgrades than enterprise re-platforming. The fit is clearest among service-led SMEs and mid-market suppliers, where the website supports procurement checks, partner reassurance and repeat lead generation.

UK adoption is a small, visibly business-facing slice: 145 actively trading companies in this list run the detected theme stack. Employment is not just a micro-company proxy, with 1,931 reported roles across the cohort and a median headcount of 6. The stack accounts for 3.8% of 3,851 detected theme instances in this business-to-business segment, below higher-share theme families ranging from 5.0% to 16.4%. Sector tags skew towards Field Services & Trades at 23.4%, Construction at 20.7% and Advanced Manufacturing at 17.2%. Registered-office geography is dispersed: London accounts for 13.8%, while Yorkshire and The Humber, the South East and the North West each account for 11.0%.
Regulation attaches to what the adopting company does with the website, not to the theme itself. Business-to-business lead capture still brings UK GDPR into scope when named contacts, email addresses or call notes are processed. The ICO's PECR guidance treats corporate subscribers differently from sole traders and individual subscribers: marketing emails to corporate bodies may not need prior PECR consent, but the sender must identify itself and offer a valid opt-out address. Live marketing calls need suppression screening against CTPS and TPS, and sector-specific rules may sit on top where the underlying activity involves finance, telecoms, professional advice or data processing.
Adoption appears likely to remain concentrated among practical commercial teams rather than software-heavy operators. These firms tend to value a maintainable site, familiar content editing and a low-friction route from search or referral traffic into an enquiry. Migration pressure may come from security maintenance, hosting changes, accessibility expectations and the bundling of forms, search optimisation and consent tooling into broader site-management workflows. The cohort also looks exposed to supplier consolidation: when agencies standardise on fewer theme and plugin combinations, smaller business-to-business suppliers often follow the stack their web partner can support cheaply and reliably.
Adoption by company size
Adoption of ThemeIsle varies by company size across the trading UK B2B companies in this cohort. 0.1% of the 76,784 companies with under 10 employees run ThemeIsle (100 detected). 0.1% of the 31,788 companies with 10–50 employees run ThemeIsle (41 detected). 0.1% of the 3,773 companies with over 50 employees run ThemeIsle (4 detected).

Key facts
About 4% of the trading cohort reports turnover above £5M (7 of 145 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (10 firms), so a sizeable share is in its first few filing cycles.
ThemeIsle accounts for 3.8% (145) of 3,851 B2B firms with a detectable website-theme system, ninth among the listed theme cohorts.
Registered addresses are dispersed: London has 13.8% (20), while Yorkshire and The Humber, the South East and the North West each have 11.0% (16).
Field Services & Trades (23.4%, 34), Construction (20.7%, 30) and Advanced Manufacturing (17.2%, 25) are the largest overlapping sector tags in the cohort.
Common co-detections point to anti-spam, block-building and search-optimisation tooling, with shares of 31.7% (46), 30.3% (44) and 30.3% (44).
ICO guidance treats B2B marketing by activity: PECR covers live or automated calls, electronic mail and fax, while UK GDPR still applies to business-contact personal data.

How ThemeIsle 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. B2B companies are identified using Firmbase's semantic classification of company activity, built from filings, websites and registered SIC codes rather than SIC codes alone. The detected counts and share figures on this page are computed within that sector cohort, so "share" always means share of B2B companies with a detectable system — not of all UK companies.
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.
