Can you integrate Stripe / Worldpay / Adyen / GoCardless / SagePay-Opayo on Magento?

Yes, all five are London-HQ'd or London-EMEA-HQ'd, we've integrated every one of them. Stripe: UK HQ in London, easiest for DTC, Stripe Elements + Apple Pay + 3DS2. Worldpay (London HQ, ex-RBS): legacy enterprise rail, strong for UK BFSI / high-AOV luxury, supports CNP and POS unification. Adyen: London office in EMEA HQ, best for multi-currency + Boxing-Day tokenisation, unified platform for online + retail. GoCardless (founded in London): BACS Direct Debit specialist, under £0.20 per transaction, perfect for subscriptions (Gousto / Pact-style F&B) and B2B Net-30. SagePay / Opayo (London since 2001, now Elavon-owned): legacy but still huge install base in UK SMB, we migrate stores away or maintain in-place. We typically wire Stripe + Adyen as primary, GoCardless for BACS B2B, and Klarna UK + Clearpay for BNPL.
