Companies Using Amazon Web Services in London: 2,383 Active Firms (2026)
Companies using cloud technology run public websites on scalable hosted computing services, across London boroughs.
Web-facing buyers tend to use this cloud infrastructure stack as production plumbing: hosting customer-facing pages, handling traffic spikes, storing site assets and connecting analytics, forms and application services. Adoption usually signals an engineering or operations function with budget for external hosting, security review and uptime management, even where the wider team is lean. The sector mix is cross-industry rather than supplier-led: SaaS accounts for 21.5% of users in this cohort, travel and hospitality for 16.7%, startup-labelled firms for 9.3%, AI and machine learning for 7.8%, and fintech for 7.0%, with category tags often overlapping.

London has 2,383 actively trading companies running this cloud stack on their public websites. Reported employment stands at 4,322 people across 119 firms, giving the adoption picture a mix of lean web businesses and larger employers. Commercial maturity is uneven. There are 185 companies with turnover above £5M, alongside 281 incorporated since 2022, so the list combines established operators with newer firms that have chosen hosted infrastructure early in their web presence.
Website hosting itself is not a licensed activity, but companies running public cloud infrastructure still inherit obligations from the services they put on it. Customer accounts, payment flows, behavioural analytics and support logs can bring UK GDPR and ICO expectations into scope, especially where personal data moves through cookies, forms or authenticated portals. Procurement tends to involve engineering, security and finance: buyers look for data-processing terms, sub-processor visibility, incident procedures and residency assurances. The operating risk is often architectural rather than contractual, because storage, content delivery, identity, monitoring and deployment tooling can become tightly coupled over time.
Adoption appears likely to track the broader shift from self-managed infrastructure towards managed cloud operations, but not every user will deepen its commitment in the same way. Lean teams tend to value managed services because they reduce operational hiring, while larger employers scrutinise resilience, privacy and cost allocation more closely. Bundling may pull more website, storage, security and deployment functions into fewer supplier relationships. At the same time, migration pressure works both ways: firms facing margin pressure may simplify their stack, while regulated or international sellers may keep more specialist controls around data handling and uptime.

Key facts
About 7% of the trading cohort reports turnover above £5M (185 of 2,383 firms) — the rest sits below that revenue band.
11% of the cohort was incorporated since 2022 (281 firms), so a sizeable share is in its first few filing cycles.
A content-delivery layer is detected alongside the public-cloud footprint at 59.7% (1,422 firms), and object storage at 51.9% (1,236).
Tag-management and web-analytics tools are common companion technologies, appearing at 45.8% (1,091) and 36.5% (869), respectively.
SaaS is the largest sector tag at 21.5% (513), followed by Travel & Hospitality at 16.7% (397); tags overlap, so the segments are not mutually exclusive.
Bot-screening tooling appears on 25.3% (604) of sites in the cohort, while 43.6% (1,038) also use an edge security or traffic-management layer.
There are 5,229 verified directors linked to the London public-cloud cohort.

How Amazon Web Services 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.
