Companies Using HighLevel in London: 134 Active Firms (2026)
Companies using CRM in London manage online lead capture, sales follow-up and customer communications from websites serving the capital.
Adoption of this CRM and marketing automation stack tends to sit with commercial operators rather than central IT teams. The buying centre is usually sales, marketing or operations, with agencies often involved in landing pages, booking flows and follow-up sequences. Companies running it are signalling a practical go-to-market setup: inbound enquiry capture, scheduled consultations, automated reminders and client onboarding managed from a common system. Typical engagements look like departmental software subscriptions, agency-managed builds and operational handovers, rather than long enterprise procurement programmes.

London has 134 actively trading companies running this CRM and marketing automation stack on public websites. Reported employment totals 1,692 people, which points to an adoption base made up mainly of small operating teams rather than large corporate estates. Only 4 companies report turnover above £5M, so the capital’s adoption picture is weighted towards owner-managed services firms, local operators and specialist commercial teams that need repeatable lead handling without building a larger internal systems function.
GDPR and ICO guidance sit close to the operating model because these sites collect contact details, booking information and customer communications through web forms and automation workflows. Sector mix also matters: education and training accounts for 18.7% of the cohort, field services and trades 17.9%, construction 14.9%, healthcare providers 11.9%, and marketing agencies 8.2%. Healthcare and education use cases tend to raise the bar for consent, retention and role-based access, while agency-run implementations can blur accountability between the website operator and the external team configuring campaigns.
Adoption appears likely to remain concentrated in smaller service businesses that need lead capture, booking and follow-up without a dedicated enterprise systems team. Bundled CRM, website and payments stacks tend to suit agencies and owner-managed operators, but they also make switching harder once workflows, forms and customer histories sit in one place. Privacy governance may become a more visible selection factor, especially where healthcare, education or paid acquisition are involved. The scarcity of larger adopters suggests gradual deepening within existing users rather than a broad move into enterprise procurement.

Key facts
About 2% of the trading cohort reports turnover above £5M (4 of 134 firms) — the rest sits below that revenue band.
12% of the cohort was incorporated since 2022 (17 firms), so a sizeable share is in its first few filing cycles.
94.0% of these users also show a closely related CRM detection label, which suggests overlapping website tags rather than isolated single-tool sightings.
57.5% also run a publishing platform and 53.0% show web-analytics instrumentation, pointing to sites where acquisition activity is being measured rather than left as brochure traffic.
Traffic and tag-management layers are common in the stack: 50.7% show a network or security layer and 47.8% show tag management.
Sector tags skew towards Education & Training at 18.7%, Field Services & Trades at 17.9%, Construction at 14.9% and Healthcare Provider at 11.9%; tags can overlap, so these shares should not be summed.
224 verified directors are attached to the London cohort, giving researchers a practical route into marketing, sales and customer-operations roles.
What else do HighLevel users run?

How HighLevel 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.
