B2B Companies Using Smush in the UK: 1,254 Active Firms (2026)
UK B2B companies running image-optimisation technology compress website media and improve page performance for business audiences.
For business-to-business suppliers, the plugin usually sits inside a website estate used for lead capture, technical proof and post-sale support, rather than consumer checkout. Adoption tends to signal an internal or retained web team, a public content-management workflow and enough search dependence for page weight to matter. Buying centres are usually marketing, digital operations and IT, with finance involved where site maintenance is wrapped into a wider agency or managed-service retainer. The fit is clearest among mid-market and larger suppliers whose product pages, case-study libraries and support assets carry commercial credibility for procurement teams.

1,254 actively trading UK business-to-business firms run the image-optimisation plugin. Reported employment totals 4,381 people across the firms that disclose headcount, which points to adoption among operating companies rather than only web-only micro-businesses. Within the detected site-plugin set for this sector, the system ranks third at 12.5% in a comparison set of 10,046 detected site-plugin uses. The registered-office skew is weighted towards London at 16.2%, followed by the North West at 12.7%, the South East at 12.2%, the East of England at 12.1% and the West Midlands at 10.7%.
Business-to-business selling is not governed by a dedicated UK licence regime; obligations follow the underlying activity, such as financial services, telecoms, data processing or professional services. For firms using performance, forms and analytics tooling in acquisition journeys, the practical centre of gravity is often direct-marketing compliance. The ICO says PECR covers live and automated calls, electronic mail and fax. Its guidance treats corporate subscribers differently for electronic mail, but senders still need to identify themselves and provide a valid opt-out address. UK GDPR continues to apply where business-contact data is processed, and live marketing calls require screening against the relevant telephone preference lists, including existing objections.
Adoption appears tied less to discretionary web design than to the routine upkeep of commercial websites. Suppliers with lean marketing teams tend to prefer tools that sit inside familiar publishing workflows, while firms with larger digital estates often push image handling closer to hosting, content delivery and deployment processes. That leaves a mixed trajectory: continued use where the plugin is part of retained site maintenance, and gradual displacement where performance work is absorbed into infrastructure, consent-management and security stacks. The cohort may therefore become more selective over time, with visible adoption concentrated among firms that keep public content libraries active.
Adoption by company size
Adoption of Smush rises with company size across the trading UK B2B companies in this cohort. 1% of the 76,784 companies with under 10 employees run Smush (783 detected). 1.3% of the 31,788 companies with 10–50 employees run Smush (424 detected). 1.1% of the 3,773 companies with over 50 employees run Smush (42 detected). That is a 0.1% gap between the over 50 employees and under 10 employees bands.

Key facts
About 7% of the trading cohort reports turnover above £5M (98 of 1,254 firms) — the rest sits below that revenue band.
5% of the cohort was incorporated since 2022 (67 firms), so a sizeable share is in its first few filing cycles.
Among 10,046 B2B firms with a detectable plugin system, the image-optimisation tool has a 12.5% (1,254) detected share, third behind two larger plugin cohorts at 19.3% (1,940) and 16.1% (1,615).
A content-management platform appears across 100.0% (1,254) of the cohort; search-optimisation, analytics and bot-checking tools appear in 63.3% (794), 58.0% (727) and 52.6% (660), respectively.
London accounts for 16.2% (203) of the cohort, followed by the North West at 12.7% (159), the South East at 12.2% (153), the East of England at 12.1% (152) and the West Midlands at 10.7% (134).
Construction (17.5%, 219), Field Services & Trades (15.6%, 195), Advanced Manufacturing (14.0%, 175) and Wholesale & Distribution (12.4%, 156) are the largest overlapping tags among B2B firms running the image-optimisation tool.
For B2B marketing, ICO guidance says PECR covers direct marketing by live or automated calls, electronic mail and fax; UK GDPR still applies where personal data is processed, including business-contact data.

How Smush 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. B2B 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 B2B 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.
Smush is a trademark of its respective owner. Firmbase is not affiliated with, sponsored by, or endorsed by the trademark owner.
