Companies Using 20i StackCP in London: 143 Active Firms (2026)
London companies running a managed hosting control panel publish public websites and digital services across the capital.
Adoption here points less to software production than to a maintained web-operations layer: hosted control-panel users need domain management, site deployment, email configuration and routine support in one place. The buyers tend to be owner-managed businesses, local-service operators and mid-market organisations where the website is a live sales or service channel rather than a static brochure. Engagements are usually modest by enterprise-IT standards, but they imply recurring spend on hosting, administration, content updates and enquiry capture. The pattern fits teams without large in-house infrastructure functions, often relying on agencies, freelancers or a small internal marketing-and-operations group to keep public channels available.

London has 143 active companies running this managed hosting stack, a relatively small adoption cohort rather than a city-wide web-technology baseline. Reported employment across the cohort totals 1,955 people, so the footprint is skewed toward small employers with some mid-market outliers. Sector tags are weighted toward Construction and Field Services & Trades, with Education & Training, Healthcare Provider and Real Estate & Property also present among the users. That mix fits a practical use case: public websites that generate enquiries, carry service information and support customer journeys, without requiring a large internal infrastructure team.
Running a hosted control panel does not create a dedicated regulatory category, but it does sit close to several compliance chores. Sites that capture enquiries, bookings or account details need GDPR-aligned notices, cookie controls and clear retention practices, with the ICO as the relevant UK regulator. Education & Training and Healthcare Provider users have a higher bar for handling sensitive submissions, even when the website itself is mostly informational. Procurement risk tends to be operational rather than strategic: domain ownership, administrator access, backup routines, supplier exit terms and agency handover documentation matter because many smaller teams rely on external web managers.
Adoption appears likely to persist among firms that want a managed route to web publishing without building infrastructure capability in-house. Migration pressure tends to come from agency changes, security incidents, performance complaints or wider website rebuild programmes rather than from the control panel itself. The cohort's small-employer skew suggests replacement decisions may be episodic and supplier-led, with hosting bundled into design, maintenance and search work. Over time, more functionality may be absorbed into broader site platforms and security services, but firms with practical, enquiry-led websites are likely to keep favouring managed administration over self-operated server estates.

Key facts
About 6% of the trading cohort reports turnover above £5M (10 of 143 firms) — the rest sits below that revenue band.
2% of the cohort was incorporated since 2022 (3 firms), so a sizeable share is in its first few filing cycles.
WordPress appears on 98.6% of the cohort's sites (141 firms), so the hosting-control-panel footprint is mostly tied to content-managed web estates.
Google Analytics is present on 46.2% of sites (66), while Elementor and Yoast SEO appear at 42.0% (60) and 40.6% (58), pointing to marketing-site administration rather than only bespoke application hosting.
Construction and Field Services & Trades each account for 15.4% of the London cohort (22 firms), ahead of Education & Training at 11.2% (16).
Cloudflare appears on 16.1% of sites (23), so most do not show that additional CDN and DNS layer alongside the hosting control panel.
There are 275 verified directors across the London cohort, which may matter for supplier mapping and account research.

How 20i StackCP 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.
