B2B Companies Using BlockMark Technologies in the UK: 648 Active Firms (2026)
B2B web-technology adopters in the UK sell products or services to other organisations while running specialist website tooling.
Adoption tends to sit with marketing, revenue operations and web teams rather than with pure engineering buyers. For business-to-business firms, a page-building layer supports campaign pages, gated content, enquiry capture and service documentation, often sitting beside analytics, tag-management and content governance tools. Running it usually signals a maintained public web estate, an identifiable owner for conversion journeys, and enough budget to use specialist agencies or in-house digital staff. The customer base is skewed towards suppliers selling to other organisations, including managed services, software, cyber, agencies and consulting, where the website has to support procurement research before sales contact.

UK adoption is relatively concentrated: 648 active trading companies are running this page-building technology, and their reported headcount totals 4,453 people. Within the page-builder category for B2B adopters, the system accounts for 2.0% of the category, placing it sixth in the ranking. Registered addresses skew south: London represents 18.8% of the cohort, the South East 16.4%, the South West 13.4%, the East of England 9.3% and the North West 9.1%. The commercial profile also leans established, with 68 companies above £5M turnover and 32 incorporated since 2022.
Business-to-business adopters sit across several regulated and unregulated markets, so obligations follow the underlying activity rather than the web stack itself. For marketing operations, the ICO position is more specific: PECR covers direct marketing through live calls, automated calls, electronic mail and fax, while the electronic-mail consent rule does not apply to corporate subscribers. That does not remove the need to identify the sender, offer a valid opt-out route, and handle business-contact data under UK GDPR. Firms using web forms, analytics and retargeting also need procurement checks around cookies, consent records, hosting locations and supplier access to personal data.
Adoption appears likely to be shaped less by pure design preference than by maintenance burden, consent management and the need to connect web journeys to sales systems. Companies running older page-building stacks tend to face pressure from accessibility work, security patching and agency dependency, while more mature operators have been standardising templates, governance and measurement across their web estates. The category therefore looks prone to gradual replacement and consolidation, especially where marketing teams want fewer plug-ins and clearer accountability for data capture. For smaller adopters, inertia may remain high because migration disrupts content, search visibility and live campaign workflows.
What’s in the file
One row per company, 50+ columns — everything below plus each company’s verified directors, from Companies House filings.
Company data
Verified directors — included
Active director count is the full Companies House board, so it can be higher than the number of names listed — we leave out nominee and formation-agent directors, who aren’t worth contacting. It’s blank for the small number of companies whose officers we haven’t fetched yet.
You’re charged per business, not per row. Where a business trades through several registered companies you get every one, and the Group Primary column marks one row per business — filter to those and the count matches your invoice. Rows sharing a website are not automatically one business: franchises and multi-site operators each count separately, and where names don’t prove a relationship we count them apart rather than guess.
Adoption by company size
Adoption of BlockMark Technologies rises with company size across the trading UK B2B companies in this cohort. 0.4% of the 76,784 companies with under 10 employees run BlockMark Technologies (313 detected). 0.9% of the 31,788 companies with 10–50 employees run BlockMark Technologies (281 detected). 1.1% of the 3,773 companies with over 50 employees run BlockMark Technologies (42 detected). That is a 0.7% gap between the over 50 employees and under 10 employees bands.

Key facts
About 10% of the trading cohort reports turnover above £5M (68 of 648 firms) — the rest sits below that revenue band.
4% of the cohort was incorporated since 2022 (32 firms), so a sizeable share is in its first few filing cycles.
Among B2B firms with a detectable page builder, this technology accounts for 2.0% (648) of 32,987 companies, behind five larger detected systems.
B2B firms running this page builder skew towards London (18.8%, 122), the South East (16.4%, 106) and the South West (13.4%, 87).
The most common co-detected website platform appears on 65.1% (422) of sites, while analytics and tag-management tools appear on 56.8% (368) and 47.5% (308), respectively.
IT Services & Managed Services accounts for 30.9% (200) of the cohort, followed by SaaS at 15.9% (103) and Cybersecurity at 13.7% (89).
For B2B marketing, the ICO says PECR electronic-mail consent rules do not apply to corporate subscribers, but senders must identify themselves and provide a valid opt-out address; UK GDPR still applies to business-contact data.

How BlockMark Technologies 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.
