IT Services Companies Using Squarespace in the UK: 165 Active Firms (2026)
IT services running hosted web platforms deliver consultancy, support and integration while presenting commerce-ready websites in the UK.
For IT services providers, a hosted website builder usually does a narrower job than the systems they implement for clients: brochure publishing, lead capture, service packaging and light commerce around audits, retainers or support bundles. Companies running the platform tend to look sales-led rather than product-led, with small marketing or operations teams favouring managed templates over bespoke web engineering. Adoption also signals a direct-channel posture: the public site is expected to explain consultancy, managed services and integration work clearly enough for inbound buyers, without making the website itself a technical showcase.

UK adoption in this narrowed IT services cohort covers 165 actively trading companies. Among 4,319 detected CMS instances across the broader sector, the hosted builder ranks fourth with a 3.8% share, behind more widely used open-source and hosted alternatives. Registered-office skew is concentrated in southern England: London accounts for 29.1%, the South East 22.4%, the East of England 10.9%, the South West 8.5% and the North West 6.1%. Reported employment across these adopters totals 1,544 people, giving the cohort a visible but mostly small-team footprint.
Regulatory exposure for these adopters sits around the services being sold rather than the website builder itself. Managed services, cyber-adjacent consultancy and telecoms support often involve client credentials, monitoring telemetry, contact forms and support requests, so GDPR, ICO expectations and clear processor language matter even when the public site is templated. Procurement teams may also read the web stack as a signal of operating depth. A simple hosted presence can be adequate for lead capture, but firms selling assurance-heavy work tend to need visible policies, certifications and service boundaries to avoid friction in supplier checks.
Adoption appears likely to remain most common among lean providers that want a low-maintenance marketing site while keeping engineering time on client delivery. Migration pressure tends to rise once firms need deeper analytics, gated content, multilingual pages, partner portals or more controlled security workflows. At the same time, the hosted-builder model still suits consultancies with repeatable service packages and modest publishing needs. The cohort therefore looks less like a frontier of web engineering than a set of commercially active operators choosing convenience, predictable upkeep and enough polish for direct sales.
Adoption by company size
Adoption of Squarespace rises with company size across the trading UK IT services companies in this cohort. 0.1% of the 119,548 companies with under 10 employees run Squarespace (108 detected). 2.5% of the 2,157 companies with 10–50 employees run Squarespace (55 detected). 2.2% of the 181 companies with over 50 employees run Squarespace (4 detected). That is a 2.1% gap between the over 50 employees and under 10 employees bands.

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. IT services 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 IT services 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.
