Companies Using JetEngine in London: 219 Active Firms (2026)
London companies running detected web technology use configurable content, listing and search features on their public websites.
Adoption usually sits with marketing, operations and web teams rather than central IT. Companies running this detected content technology tend to need editable listings, searchable directories, staff or course pages, property-style catalogues, location pages, or service hubs that non-technical teams can maintain. That points to a website doing more than brochure work: it is part of lead capture, recruitment, customer information or service delivery. Buying often runs through an agency or retained web partner, with internal ownership shared between marketing, compliance and service teams. The fit is usually a budget-conscious operating business, not a firm selling the underlying software.

London has 219 companies running this detected technology on public websites. Reported employment across the cohort totals 2,021 people, which points to an adoption base made up mainly of small operating businesses rather than large enterprise estates. The sector mix is fairly broad: Education & Training and Construction each account for 11.0% of detected users, with Management Consulting at 10.0%, Real Estate & Property at 9.6%, and Wholesale & Distribution at 9.1%. Turnover scale is uneven, with 14 companies reporting more than £5M and 22 incorporated since 2022.
UK website operators are not licensed merely for running this kind of web stack, but public-facing use brings familiar cross-sector obligations. ICO guidance under PECR requires operators to tell visitors when cookies are set, explain what they do and why, and obtain consent that is actively and clearly given unless an exemption applies. Non-anonymous cookie information can also bring the Data Protection Act and UK GDPR into scope, while strictly necessary cookies may be exempt. For buyers, the practical market structure is agency-led and plug-in-dependent, so procurement tends to focus on consent controls, update responsibility, hosting arrangements and evidence that form or tracking choices match stated privacy notices.
Adoption appears likely to remain concentrated among organisations that want editable, search-led content without commissioning a fully bespoke platform. The trade-off is maintenance: plug-in-heavy websites can meet operational needs cheaply at first, but responsibility for updates, consent controls and performance often becomes less clear as sites accumulate features. Mid-market users with larger content operations may keep the pattern if agencies provide reliable governance; others may migrate towards bundled website platforms or narrower vertical systems. The scarcer group is businesses that treat this stack as a long-term operating layer rather than a tactical build for marketing pages.

Key facts
About 6% of the trading cohort reports turnover above £5M (14 of 219 firms) — the rest sits below that revenue band.
10% of the cohort was incorporated since 2022 (22 firms), so a sizeable share is in its first few filing cycles.
100.0% of the cohort also run the underlying content management system, and 96.3% also run a visual page-building layer.
Measurement and form-protection tooling is common: 52.1% run analytics, 50.7% run anti-spam checks and 39.7% run tag management.
The sector mix is dispersed, with Education & Training and Construction each at 11.0%, followed by Management Consulting at 10.0%.
The ICO’s PECR guidance requires website operators to explain cookies and obtain consent that is “actively and clearly given”; non-anonymous cookie data can also trigger Data Protection Act and UK GDPR duties.
The UK Digital Sector accounted for 6.8% of total UK GVA in 2024, or £177.2 billion in current prices, with digital GVA up 3.3% between 2023 and 2024 after inflation.

How JetEngine 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.
