Companies Using Reviews.io in London: 102 Active Firms (2026)
London companies running review tools collect and display customer feedback on their websites for ecommerce, services and lead-generation journeys.
Adoption typically sits with growth marketing, ecommerce trading and customer operations rather than core IT. The tool is bought to make trust signals visible at checkout, on category pages and in lead-generation funnels, with post-purchase review requests feeding the public widget. Companies running this stack tend to be transaction-led retailers, marketplaces, consumer services providers and quote-led operators where conversion rate and complaint handling meet. The buying motion is usually a modest web and operations project: marketing owns the commercial case, customer support owns the review workflow, and developers or an agency handle tags, templates and schema markup.

London has 102 active companies running this review-widget stack, a small, commercially focused cohort rather than a broad software category. Reported employment totals 1,152 people, with a median headcount of 8, which points to lean operating teams using reviews as part of web trading rather than large research or product organisations. Sector tags are weighted towards online commerce: e-commerce accounts for 30.4% of the cohort, fashion and retail 13.7%, wholesale and distribution 11.8%, logistics and supply chain 10.8%, and field services and trades 9.8%.
Review widgets sit close to consent, marketing and consumer-protection questions. Review requests often use email or SMS after a purchase, so permissioning, suppression lists and audit trails need to line up with GDPR and ICO expectations. The public display layer adds another risk: moderation policies, incentive disclosures and star-rating presentation can influence purchase decisions, so operators need a defensible process for rejecting abusive content without filtering out legitimate criticism. Procurement is usually lighter than for payments or identity tooling, but website agencies and ecommerce teams still scrutinise uptime, portability of review histories and integration with tagging, analytics and checkout systems.
Adoption appears tied to the pressure on consumer-facing sites to make reassurance visible before checkout or enquiry submission. New users tend to arrive when internal marketing teams formalise lifecycle messaging, or when an agency rebuild exposes gaps in trust signals and structured content. Switching may remain relatively low because review histories, templates and internal moderation habits become embedded over time. Consolidation is more likely to show up through bundled ecommerce, analytics and customer-communications stacks than through wholesale replacement, while privacy scrutiny should keep pushing teams towards clearer consent capture and cleaner separation between review collection, marketing automation and web analytics.

How Reviews.io 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
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.
