Companies Using Ninja Forms in London: 373 Active Firms (2026)
Companies using website form tools collect enquiries, registrations and customer data through public web forms, across London boroughs.
At the website layer, Ninja Forms users tend to rely on embedded form tooling that lets non-technical teams build and maintain structured forms inside the public site: contact routes, registrations, applications, bookings, newsletter sign-ups and support intake. Running it tends to signal a company that is already invested in its web presence, but not necessarily buying enterprise workflow software. The buyer is often a marketing, operations or office-administration function that wants configurable fields, notifications and consent capture without a separate application build. Typical engagements are modest and departmental, although the same setup can sit inside more formal customer-acquisition or stakeholder-management processes.

London has 373 actively trading companies running Ninja Forms on public websites. The adoption picture is skewed towards practical inbound capture rather than large software programmes: enquiries, applications, bookings, registrations and support requests sit close to marketing, operations and customer-service teams. Reported headcount totals 2,564 employees, which points to a mostly small-employer base with a thinner mid-market layer. The sector mix also looks operationally grounded, with healthcare, construction, field services, wholesale and property businesses using forms to move routine offline interactions into structured digital workflows.
UK GDPR and the Data Protection Act apply when these forms collect personal information, so ownership does not end with the web team. ICO expectations reach into privacy notices, retention, access controls and supplier oversight, while PECR adds a separate layer for electronic marketing and cookies or similar tracking. Consent for non-exempt cookies and some marketing activity has to meet the UK GDPR standard, rather than a looser website preference. Enforcement can include prosecution, non-criminal enforcement, audit and monetary penalties, which makes form design, tagging and consent logging part of ordinary governance rather than a cosmetic website decision.
Adoption appears likely to stay connected to the economics of the wider web stack. Many users value the low-admin route from website enquiry to inbox, case list or mailing workflow, but migration pressure tends to build when consent management, spam controls or back-office integration become harder to maintain. Smaller operators may keep familiar form setups for long periods because replacement rarely has board-level urgency. Larger or more regulated organisations are more likely to rationalise forms into central customer platforms, especially where audit trails, accessibility and data-retention policies need a clear owner.

Key facts
About 6% of the trading cohort reports turnover above £5M (26 of 373 firms) — the rest sits below that revenue band.
12% of the cohort was incorporated since 2022 (45 firms), so a sizeable share is in its first few filing cycles.
Every firm in the London cohort also runs the same underlying CMS, making this form-tool list part of a wider CMS-dependent website stack rather than a standalone software market.
SEO tooling appears on 62.2% of these sites, while analytics tagging appears on 45.0%, suggesting ordinary acquisition and measurement use cases around public web forms.
Cookie and consent tooling appears on 21.4% of sites, while bot-check tooling appears on 30.3%, reflecting privacy and spam-control requirements around form submissions.
Healthcare providers and construction firms each account for 12.3% of the London cohort, followed by field services and trades at 11.3%.
UK organisations collecting personal data through web forms are in scope of UK GDPR and the Data Protection Act, with PECR also relevant where forms connect to electronic marketing or non-exempt cookies.

How Ninja Forms 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.
