Companies Using ShareThis in London: 311 Active Firms (2026)
Website operators using social sharing widgets embed third-party scripts for content sharing and audience engagement across London.
Marketing, ecommerce and audience-development teams are the usual owners, with compliance and web-ops involved once tags, consent and page performance become material. Adoption usually signals a public-facing site with measurable acquisition targets: online retailers, publishers, property marketplaces, training providers and services firms that want content distribution tracked alongside search, display and analytics activity. For most companies running this kind of social-sharing script, the commitment is less a large software procurement than an operating choice inside the website stack, owned by teams with recurring campaign, conversion and consent responsibilities.

London has 311 actively trading companies running this social-sharing technology, so adoption is visible but still a relatively selective signal across the capital’s public-web economy. Reported employment totals 1,635 people, pointing to a cohort weighted towards small operators rather than large enterprise web estates. The sector mix is skewed towards commercial and content-led sites: real estate and property, construction, media and publishing, field services and trades, and education and training all appear among the more common adopter categories.
PECR and UK GDPR matter more than the sharing button itself. The ICO treats cookies, tracking pixels, device fingerprinting, web storage, scripts and tags as part of the same consent and transparency problem where they store or access information on a user’s device. Non-essential cookies used for advertising or analytics need prior consent, clear explanation and no pre-ticked boxes; legitimate interests cannot be used as a fallback for marketing and advertising cookies. For buyers, procurement tends to centre on consent flows, tag governance, contractual controls and evidence that site performance is not being quietly degraded.
Adoption appears likely to become more selective rather than simply broader. Cookie and tag scrutiny has been pushing website owners to rationalise scripts, shorten tag chains and move more measurement into governed analytics environments. Smaller firms may keep simple social buttons where referral traffic is visible, while mid-market operators tend to ask whether each script justifies its consent burden and page-weight cost. The result is a cohort that may change through substitution and bundling as much as through new uptake, with compliance and marketing operations setting the pace.

Key facts
About 5% of the trading cohort reports turnover above £5M (17 of 311 firms) — the rest sits below that revenue band.
7% of the cohort was incorporated since 2022 (22 firms), so a sizeable share is in its first few filing cycles.
UK organisations using third-party scripts, tags, cookies, tracking pixels or similar storage/access technologies sit under PECR and UK GDPR oversight by the ICO.
ICO guidance finalised on 29 April 2026 covers cookies, tracking pixels, device fingerprinting, web storage and scripts or tags.
PECR requires consent for non-essential cookies; they must not be set before consent, pre-ticked boxes cannot be used, and marketing or advertising cookies cannot rely on legitimate interests.
A content-management platform appears alongside the sharing widget on 57.9% of London cohort websites (180 firms), while a web-analytics tag appears on 45.3% (141).
IAB UK reported UK digital ad spend of £35.5 billion in 2024, up 13%, with search at £16.6 billion and video display at £8.3 billion.

How ShareThis 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
