Marketing Agency Companies Using Squarespace in the UK: 453 Active Firms (2026)
Marketing agencies using hosted site builders create campaigns, content and ecommerce-ready websites for UK clients.
For a marketing agency, a hosted site-builder stack is usually the agency’s own demand-generation layer rather than the whole delivery model. It lets account and content teams publish service pages, sector proof points, campaign landing pages, lead forms and lighter ecommerce offers without depending on a dedicated engineering function. Adoption tends to signal a services-led agency with a direct-channel posture: enough budget for paid acquisition, analytics and conversion tracking, but an operating model that still values quick edits and repeatable templates over bespoke platform work. Client engagements are likely to range from retained campaign support to project-based website and content packages.

Some 453 UK marketing agencies are running this hosted site-builder stack. Within the marketing-agency CMS set, it ranks second at 9.4% of 4,808 detected sites, behind a higher-share incumbent and just ahead of adjacent hosted-builder and visual-development tools. Reported headcount totals 1,349, which fits a cohort weighted towards lean service teams rather than national agency networks. The registered-address skew is London-heavy: London accounts for 39.5% of the cohort, followed by the South East at 16.3%, the South West at 9.5%, the North West at 6.8% and the East of England at 6.4%.
Marketing agencies are not subject to a single sector licence, but the work attached to this stack often touches regulated communications. The ICO regulates data protection and PECR for direct marketing, including consent, cookies and prospecting practices. Ofcom covers misuse of public electronic communications networks, while the CMA and trading standards sit behind unfair-trading enforcement. The ASA enforces the CAP Code, whose rules apply to advertisers, agencies and media, so a hosted landing page can still carry advertising-standards risk. DMA members also face the DMA code as a trade-body obligation, particularly where campaigns use email, telephone or other direct channels.
Adoption appears likely to remain concentrated among agencies that sell packaged website, content and performance-marketing work rather than custom engineering. The stack suits firms where consultants, designers and marketers need to amend pages themselves, while more technically complex clients may still pull agencies towards open-source CMS, commerce platforms or headless builds. Consent management, analytics governance and client handover terms should matter more over time, because the agency’s own site often doubles as a proof point for its delivery method. Migration pressure may come from bundled marketing suites and from clients asking for cleaner ownership of templates, domains and conversion tracking.
Adoption by company size
Adoption of Squarespace rises with company size across the trading UK marketing agency companies in this cohort. 0.6% of the 54,246 companies with under 10 employees run Squarespace (311 detected). 7.1% of the 1,903 companies with 10–50 employees run Squarespace (135 detected). 3.4% of the 146 companies with over 50 employees run Squarespace (5 detected). That is a 2.8% gap between the over 50 employees and under 10 employees bands.

Key facts
About 3% of the trading cohort reports turnover above £5M (14 of 453 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (28 firms), so a sizeable share is in its first few filing cycles.
Among 4,808 UK marketing agencies with a detectable CMS, this hosted website-builder system has 9.4% detected share (453), behind the largest CMS at 67.7% (3,254).
London accounts for 39.5% (179) of the detected cohort, followed by the South East at 16.3% (74) and the South West at 9.5% (43).
Stack instrumentation is uneven: 45.7% (207) also run analytics tooling, while 17.7% (80) also run tag-management tooling.
UK ad spend reached £42.6 billion in 2024, up 10.4%, with online formats growing 13.2% and £4 in every £5 of ad budgets spent online.
Campaign work is not licensed through a single sector regulator; direct marketing can involve the ICO and PECR, while the ASA applies the CAP Code to advertisers, agencies and media.

How Squarespace 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.
