Companies Using Klarna in the UK: 597 Active Firms (2026)
Pay-later adopters in the UK run deferred-payment checkout options on public websites for consumer-facing online sales.
Adoption usually sits with ecommerce, trading and payments teams rather than with engineering alone. Deferred-payment checkout is used where conversion, average order value and returns handling are live commercial questions, especially among direct-to-consumer retailers, travel sellers, marketplaces and specialist online merchants. Running this type of checkout option tends to signal a company with a measurable online sales operation, enough payment volume to justify third-party payment integrations, and a customer base that expects choice at the point of purchase. Engagements are typically operational rather than experimental: checkout configuration, risk settings, refunds, customer-service scripts and finance reconciliation all have to work together.

The UK adoption picture contains 597 active companies running deferred-payment checkout. Reported employment across the cohort is 3,097 people, with headcount disclosed by 122 firms. The base skews towards consumer commerce: ecommerce accounts for 55.9% of the cohort, fashion and retail for 33.2%, and wholesale and distribution for 21.6%, with categories overlapping where firms both sell directly and distribute to trade customers. Median reported headcount is 7, while median turnover is about £750k, so many adopters look like specialist operators rather than large retail groups. A further 77 companies report turnover above £5M.
Deferred-payment checkout sits between retail merchandising and consumer-credit governance. For merchants, the practical burden is less about owning the finance product and more about controlling how it is presented: checkout copy, eligibility prompts, refund flows, complaints routing and customer-service training all matter. Procurement also cuts across teams. Ecommerce owners may sponsor the integration, but finance teams care about settlement timing and reconciliation, while privacy and marketing teams need to align tracking, consent and abandoned-basket activity. Co-occurrence with analytics, tag-management, fraud-checking and wallet-style payment tools points to a checkout stack managed as part of the wider conversion infrastructure, not as a standalone payment button.
Adoption appears to be moving from novelty into checkout plumbing. Consumer sellers that already manage several payment routes tend to treat deferred payment as another configurable option, while smaller merchants may keep it only where it can be maintained without extra operational work. Scrutiny of credit presentation should keep pressure on plain-language disclosures, refunds and complaint handling. The more mature adopters are likely to rationalise payment and analytics stacks around fewer operational dependencies, rather than adding every available checkout option. Consolidation in the wider payments ecosystem may also make pay-later functionality feel less like a separate decision over time.

Key facts
About 12% of the trading cohort reports turnover above £5M (77 of 597 firms) — the rest sits below that revenue band.
5% of the cohort was incorporated since 2022 (33 firms), so a sizeable share is in its first few filing cycles.
E-commerce is attached to 55.9% (334) of the pay-later checkout cohort; sector tags overlap.
Fashion and retail appears on 33.2% (198) of profiles, second only to e-commerce among the listed sector tags.
Wholesale and distribution appears on 21.6% (129), indicating adoption among trade-facing merchants as well as consumer retailers.
60.5% (361) also run traffic-protection and content-delivery tooling, while 58.6% (350) also run tag-management tooling.
49.4% (295) also run wallet or payment-button technology, so pay-later checkout often sits beside alternative payment routes.

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