Marketing Agency Companies Using Amazon S3 in the UK: 150 Active Firms (2026)
Marketing agencies using cloud object storage run campaign assets, analytics feeds and web delivery workflows for UK clients.
For marketing agencies, this object-storage stack usually sits behind campaign asset libraries, landing-page media, analytics exports and client content-delivery workflows rather than acting as a client-facing product. Adoption tends to signal a team with developers or technically literate marketing operations staff, not just designers and account handlers. Buyers are normally business clients with paid-media, creative production, performance marketing or marketing-operations requirements, and engagements are often retainer-led with project work around launches. The stack suits agencies handling enough web traffic, media variation and measurement plumbing to need cloud-hosted storage rather than ad hoc file sharing.

Across the UK, 150 marketing agencies are actively trading while running this object-storage stack on public web properties. The agencies account for 1,637 reported employees across the cohort. Within detected CDN and delivery technologies used by marketing agencies, the stack ranks second at 6.2% of a 2,435-company sector denominator, behind an edge-networking option at 94.2% and ahead of a cloud-delivery layer at 3.0%. Registered-office skew is concentrated but not exclusively London-based: London accounts for 34.0% of these adopters, followed by the South East at 18.0% and the East of England at 9.3%.
Marketing agencies using cloud storage do not sit under a sector-wide licence, but campaign delivery brings them into several rulebooks. The ICO is central where audience data, tracking identifiers, email lists or client customer files move through storage and analytics workflows, with PECR especially relevant to direct marketing. ASA enforcement of the CAP Code also reaches agencies and media owners, not just advertisers. Unfair-trading oversight by the CMA and trading standards, plus Ofcom’s role around misuse of public electronic communications networks, creates a fragmented compliance perimeter. Procurement therefore tends to ask where assets are hosted, who can access them, and how client data is separated.
Adoption appears more likely among agencies with in-house technical staff and repeatable digital-delivery workflows than among creative boutiques built around account service and outsourced production. The stack tends to be chosen when campaign assets, analytics exports and landing-page media need a more durable storage layer, although many smaller agencies may continue to rely on bundled website hosting, collaboration suites or managed partners. Procurement pressure around privacy, access control and client separation should favour clearer governance over novelty. Over time, usage may become less visible as storage is bundled behind web hosting, analytics and content-delivery services, making direct detection a partial view of actual reliance.
Adoption by company size
Adoption of Amazon S3 rises with company size across the trading UK marketing agency companies in this cohort. 0.2% of the 54,246 companies with under 10 employees run Amazon S3 (102 detected). 2.2% of the 1,903 companies with 10–50 employees run Amazon S3 (42 detected). 5.5% of the 146 companies with over 50 employees run Amazon S3 (8 detected). That is a 5.3% gap between the over 50 employees and under 10 employees bands.

Key facts
About 8% of the trading cohort reports turnover above £5M (12 of 150 firms) — the rest sits below that revenue band.
4% of the cohort was incorporated since 2022 (7 firms), so a sizeable share is in its first few filing cycles.
The selected cloud-object-storage system has a 6.2% detected CDN share among 2,435 marketing agencies with a detectable system.
London accounts for 34.0% of detected users, followed by the South East at 18.0% and the East of England at 9.3%.
An adjacent cloud-platform service is detected alongside the storage setup in 100.0% of the cohort; analytics, edge-network and content-management tools follow at 61.3%, 56.7% and 56.0%.
UK ad spend reached £42.6 billion in 2024, up 10.4%, with online formats up 13.2% and £4 in every £5 of ad budgets spent online.
Direct-marketing work sits under ICO data-protection and PECR rules, while Ofcom, the CMA, trading standards and the ASA’s CAP Code can also apply depending on channel and claim.

How Amazon S3 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. marketing agency companies are identified using Firmbase's semantic classification of company activity, built from filings, websites and registered SIC codes rather than SIC codes alone. The detected counts and share figures on this page are computed within that sector cohort, so "share" always means share of marketing agency companies with a detectable system — not of all UK companies.
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.
