Companies Using PayU in London: 646 Active Firms (2026)
Companies running online payment technology in London accept card and digital payments through public websites across the capital.
Adoption tends to sit inside transactional websites rather than back-office finance projects. Companies running this payment stack usually need an embedded checkout that can take card or wallet payments, pass settlement details into finance workflows, and support refunds without moving buyers into a manual invoice process. The buying centre is often split between commercial owners, finance teams and web agencies, with compliance or operations pulled in where bookings, subscriptions, donations or ticketing create refund and reconciliation work. It tends to signal an organisation with live acquisition through its website, budget for maintained payment infrastructure, and enough internal or agency support to keep checkout, analytics and customer records aligned.

London has 646 actively trading companies with this payment technology detected on public websites, making the adoption picture fairly specialised rather than a generic ecommerce proxy. The employment footprint is modest: headcount-reporting firms account for 1,612 roles, and the median user is a small employer. Sector mix points toward operational services as much as retail checkout, with field services and trades at 44.0% of the cohort, construction at 13.5%, wholesale and distribution at 9.0%, and both FMCG and fashion and retail at 8.5%. That blend suggests payment acceptance is often attached to bookings, deposits, account settlement and repeat orders, not only basket checkout.
Using an embedded payment service does not usually make a merchant a payment-services firm, but it does move checkout into procurement and compliance review. London users still need supplier due diligence around settlement terms, fraud tooling, refund rights, chargebacks and service availability, especially where paid bookings or subscriptions create recurring customer contact. GDPR also matters where payment events are tied to customer accounts, marketing tags or support records. The regulated perimeter normally sits with authorised payment providers, while the merchant is left with contractual controls and operational evidence for disputes.
Adoption appears likely to stay tied to practical checkout maintenance rather than a broad platform shift. Smaller London users tend to keep the stack when it works, because payment migration touches refunds, customer records, finance reconciliation and website templates. The pressure points are likely to come from bundled commerce tools, tighter fraud screening and the need to keep consent, analytics and payment records consistent. Consolidation in the vendor layer may reduce the range of plausible options, but merchants with mixed booking, subscription and account-settlement flows still have reasons to run specialist payment infrastructure alongside their wider website stack.

Key facts
About 1% of the trading cohort reports turnover above £5M (11 of 646 firms) — the rest sits below that revenue band.
10% of the cohort was incorporated since 2022 (65 firms), so a sizeable share is in its first few filing cycles.
Four co-occurring enterprise software services appear across 99.8% (645) of the London payment-gateway cohort, suggesting a repeatable website stack rather than isolated checkout deployment.
Field Services & Trades accounts for 44.0% (284) of the cohort, ahead of Construction at 13.5% (87).
Wholesale & Distribution represents 9.0% (58), while FMCG and Fashion & Retail each account for 8.5% (55).
987 verified directors are attached to these London companies.
The financial-health split is mixed: 23.1% (149) sit in the stable band, 17.8% (115) in the weak band and 6.5% (42) in the distressed band.

How PayU 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.
