Companies Using ActiveCampaign in London: 1,778 Active Firms (2026)
London companies running marketing automation on their websites use email, CRM and lead-nurture workflows to convert and retain customers across the capital.
Usage tends to cluster around commercial teams that already own audience capture, campaign cadence and contact governance: marketing operations, revenue operations, ecommerce trading, membership engagement and service-led customer success. Companies running this stack usually sell through business-to-business, retail, education, media or professional-services models where repeat contact has value. Adoption signals more than a newsletter habit. It usually means the organisation has enough budget and operating process for configured journeys, CRM hand-offs, suppression lists and attribution, though not always a dedicated marketing-technology function. Engagements are often departmental at first, with sales, marketing and operations sharing ownership.

London has 1,778 actively trading companies running this marketing-automation stack. The reported employment footprint totals 1,777 people, pointing to an adoption base with many small operating teams rather than a market made up only of large enterprise estates. The sector mix is not purely software-led: Field Services & Trades accounts for 20.9% of the cohort, Construction 11.3%, Beauty & Personal Care 9.7%, Fashion & Retail 9.1% and Travel & Hospitality 9.0%. That spread fits a tool used for bookings, quotes, repeat purchase and membership-style contact, not just subscription software.
Email and customer-journey tooling brings the usual PECR, UK GDPR and Data Protection Act questions into day-to-day marketing operations. The ICO treats direct marketing as advertising or marketing material directed at particular individuals, and PECR is stricter for people than for corporate subscribers. For corporate email and text marketing, consent under PECR is not normally required, but senders still need to identify themselves and offer a valid opt-out route. Sole traders and some partnerships sit closer to individual-subscriber treatment, so consent or the soft opt-in matters. UK GDPR continues to apply where named business contacts are processed.
Adoption appears likely to remain tied to practical migration choices rather than a clean break between categories. Smaller London operators tend to add automation when newsletters, enquiries and repeat purchases outgrow manual handling, while more mature users tend to reassess overlap between email, CRM, analytics and customer-service systems. Vendor bundling may put pressure on standalone workflows, but contact governance and consent management keep the category relevant. Consolidation should therefore look uneven: some firms will absorb automation into broader commercial platforms, while others will keep a dedicated tool because campaign ownership sits outside central IT.

Key facts
About 3% of the trading cohort reports turnover above £5M (64 of 1,778 firms) — the rest sits below that revenue band.
11% of the cohort was incorporated since 2022 (202 firms), so a sizeable share is in its first few filing cycles.
The co-occurrence pattern is clustered: three other detected technologies appear alongside this automation tool in 70.8%, 70.8% and 70.6% of the London cohort.
Sector tags overlap, but field services and trades account for 20.9% of the London cohort, construction 11.3%, beauty and personal care 9.7%, fashion and retail 9.1%, and travel and hospitality 9.0%.
PECR, UK GDPR and the Data Protection Act apply where marketing automation processes named business contacts, with the ICO treating sole traders and some partnerships as individual subscribers.
For B2B email and text marketing, the ICO says PECR consent is not needed for messages to corporate bodies, but senders must identify themselves and provide a valid opt-out address.

How ActiveCampaign 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.
