Companies Using Flywheel in London: 203 Active Firms (2026)
Companies using managed website hosting run public sites on outsourced infrastructure, with registered offices across London boroughs.
Flywheel users tend to be organisations for which the website is an operating asset rather than a brochure. The platform handles managed hosting, routine administration and performance and security upkeep, so buying centres usually sit between marketing, operations and outsourced web agencies rather than central IT alone. Adoption points to regular content publishing, paid or organic lead generation, and a need for predictable site management without building a large infrastructure function. Engagements are usually modest in enterprise-software terms: retainers, hosting support, content workflow and monitoring, often overseen by a small internal digital owner.

London has 203 active companies running Flywheel, making this a fairly small adoption cohort rather than a mass-market signal across registered businesses. Reported headcount totals 1,818 employees, so the footprint looks concentrated in SMEs with maintained web operations rather than large infrastructure departments. The buyer profile fits London’s service-heavy economy: marketing agencies, property firms, construction businesses, healthcare providers and trades businesses all need public sites that can support enquiry capture, content updates and basic customer trust. The common thread is website dependence, not software publishing.
Procurement is usually less about formal software selection and more about accountability for a public-facing site. Companies running Flywheel still need contracts that cover uptime expectations, backups, incident handling, administrator access and exit arrangements, particularly where an external agency controls the environment. Sites that collect enquiries, appointment requests or newsletter sign-ups also carry data-protection and cookie-consent obligations; analytics and tagging choices can widen the compliance surface. For regulated customer sectors, the practical concern is often auditability: who changed the site, who can see submitted customer details, and how content is approved before publication.
Adoption appears likely to track the wider shift from one-off website builds towards retained site operations. Migration pressure tends to come from ageing self-managed hosting, security maintenance and the need to connect websites with marketing systems. At the same time, bundling by agencies may keep the stack relatively sticky: many clients experience the platform through a service relationship rather than a direct infrastructure choice. Consolidation risk sits more in the surrounding agency and tooling layer than among the end users themselves.

Key facts
About 3% of the trading cohort reports turnover above £5M (8 of 203 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (13 firms), so a sizeable share is in its first few filing cycles.
Co-detection is universal with the underlying content-management system: 100.0% of sites in the cohort show that pairing.
Search-optimisation tooling appears on 62.1% of these sites, ahead of analytics tags at 47.3% and tag-management scripts at 41.4%.
Verification and edge-network components are present on 38.9% and 32.0% of the cohort respectively, so site security and delivery services often sit alongside managed hosting.
Marketing agencies form the largest sector tag at 12.3%, ahead of real estate and property at 8.9%, construction at 8.4%, healthcare providers at 7.9%, and field services and trades at 7.4%.
The credit view is mixed: 24.6% of the cohort is classified as stable, while 19.7% is weak, 5.9% distressed, and 4.4% has insufficient history.

How Flywheel 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
