Marketing Agency Companies Using SiteGround in the UK: 310 Active Firms (2026)
Marketing agencies using managed hosting build, host and optimise campaign websites for UK clients under data-protection and marketing rules.
Within agency operations, the platform sits closest to production and performance teams rather than media-buying desks. Use tends to signal a direct-channel agency with in-house website delivery, search specialists and analytics staff, but not necessarily an infrastructure team large enough to manage servers itself. Engagements are likely to be recurring retainers or campaign-site builds where uptime, publishing workflow and tag governance matter to client service. The buyer is usually an operations, digital delivery or marketing-technology lead balancing client deadlines with outsourced hosting, rather than a central IT procurement function.

The UK adoption picture is modest: 310 actively trading marketing agencies run this managed-hosting stack on their public websites. Reported employment across agencies with headcount filings totals 1,938, while 121 of 121 agencies with coverage report some employment. Within detected hosting use among UK marketing agencies, the stack sits second in the hosting ranking, with a 29.6% share within 1,049 detected hosting deployments across the sector. Registered offices skew towards London at 31.6% and the South East at 17.4%, followed by the North West at 9.7%, South West at 8.1% and East of England at 5.5%.
UK agencies using third-party hosting are not licensed as a sector, but their campaign work crosses several rulebooks. The ICO is the main reference point for data protection and PECR in direct marketing, especially where hosted landing pages collect leads, set cookies or trigger email and SMS follow-up. Ofcom, the CMA, trading standards and the ASA can also be relevant, depending on the channel and claim being made; the CAP Code applies to advertisers, agencies and media. Procurement therefore tends to focus on processor terms, access controls, incident handling and evidence that consent choices can be honoured across client campaigns. The DMA code adds a trade-body layer for members.
Adoption appears tied to agencies’ direct-channel posture rather than to hosting as a standalone procurement exercise. The cohort tends to sit at the owner-managed and small-agency end, so buyers are likely to value predictable maintenance, familiar publishing workflows and fewer internal infrastructure tasks. Over time, managed hosting may be judged less on raw hosting capability and more on how well it fits consent management, analytics hygiene and client-reporting routines. Bundling by larger website platforms could narrow choice, while privacy expectations push agencies towards cleaner governance of tags, forms and access rights.
Adoption by company size
Adoption of SiteGround rises with company size across the trading UK marketing agency companies in this cohort. 0.4% of the 54,246 companies with under 10 employees run SiteGround (211 detected). 4.8% of the 1,903 companies with 10–50 employees run SiteGround (91 detected). 4.1% of the 146 companies with over 50 employees run SiteGround (6 detected). That is a 3.7% gap between the over 50 employees and under 10 employees bands.

How SiteGround 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.
