Best Card Issuing Platforms in the UK (2026): Issuers, BaaS Providers and Programme Managers Compared

You want to launch cards in the UK. Then you open the vendor list and see issuer processors, BIN sponsors, EMIs, BaaS platforms and programme managers, all claiming to do card issuing. They do different jobs. Picking the wrong one can cost you months. This guide sorts 13 UK card issuing platforms by what they actually do.

How does card issuing work in the UK?

A UK card programme needs four roles: a BIN sponsor, an issuer processor, a programme manager and the brand that owns the customer. Some card issuing companies cover one role. Others bundle all of them.

Here is who does what.

• BIN sponsor (principal member). The regulated entity that holds the issuing licence with Visa or Mastercard and carries ultimate liability. It usually owns the settlement accounts and needs a reserve to cover the daily settlement position. In the UK, this is typically an FCA-authorised e-money institution (EMI) or a bank.
• Issuer processor. The technology that authorises transactions, manages card lifecycles and connects to the card schemes.
• Programme manager. The company that runs the card programme day to day: onboarding, compliance oversight, scheme relationships and vendor management. Sometimes this is you. Often it is a BaaS provider.
• Card brand. Your company. You own the product, the customer and the experience.

A common UK setup looks like this: an FCA-authorised EMI with scheme membership sponsors a programme manager, which runs on an issuer processor.

The card issuing process, step by step

The card issuing process takes a UK programme from idea to live cards in six stages. Most of the time goes into due diligence and integration.

1. Choose your model. Decide between an all-in-one card issuing platform and a separate issuer processor plus BIN sponsor.
2. Pass due diligence. Your BIN sponsor reviews your business, ownership, compliance setup and financial position before it signs.
3. Design the programme. Define card types (debit, prepaid, credit, virtual), limits, fees and card artwork. The card scheme approves the programme and the design.
4. Integrate. Connect your app to the card issuing API for card creation, authorisations and webhooks. Add customer onboarding, your ledger and tokenisation for Apple Pay and Google Pay.
5. Test and certify. Run end-to-end tests in the provider’s sandbox and complete any certification your processor requires.
6. Launch in stages. Start with a pilot group, watch authorisation rates and disputes, then open to everyone.

What changed for UK card issuers in 2026?

The biggest change is safeguarding. The FCA’s new safeguarding rules for payments and e-money firms (CASS 15) came into force on 7 May 2026 (FCA PS25/12).

For e-money card programmes, that means daily reconciliations, a monthly safeguarding return and, above a funds threshold, an annual safeguarding audit. Your BIN sponsor carries this obligation. Your platform and your data still need to support it.

Two more things to keep on your radar:

• Consumer Duty. The FCA’s review of 23 payments and e-money firms found just under half had only partially implemented the Duty. Weak oversight of agents and distributors was one of the issues (FCA). That matters directly for programme manager models.
• PSR moving into the FCA. HM Treasury confirmed in April 2026 that the Payment Systems Regulator will be abolished and its functions moved to the FCA. No date is set yet (GOV.UK).

On the scheme side, Visa launched its Flexible Credential in the UK on Zilch cards in May 2026, with Thredd handling processing. One card, several ways to pay. Expect more UK issuers to ask their processors about it.

Best issuer processors in the UK

Issuer processors give you the most control and the most work. You will still need a BIN sponsor and someone to manage the programme.

1. Thredd

Thredd (formerly GPS) is an issuer processor with UK operations in London. It powers card programmes for 130+ clients in more than 50 countries. It supports credit, debit, prepaid and virtual cards, Apple Pay, Google Pay and Samsung Pay, on Visa, Mastercard and Discover.

Recent UK work includes processing for Zilch’s launch of Visa Flexible Credential in May 2026 and Vault’s UK and Australia expansion. For the integration model, see our Thredd issuer processing guide.

Choose Thredd if you want deep control over authorisation logic and you already have, or plan to get, a BIN sponsor.

2. Marqeta

Marqeta is a modern card issuing platform known for its open APIs, Just-in-Time (JIT) funding and dynamic spend controls. With JIT funding, your own system approves or declines each authorisation, and Marqeta gives you 3 seconds to respond.

In August 2025 Marqeta completed its acquisition of TransactPay, an EMI licensed in the UK and EEA. That lets Marqeta offer programme management and BIN sponsorship in Europe, along with processing. In the UK, OakNorth uses Marqeta for commercial cards. If you are comparing Marqeta alternatives in the UK, Thredd and Paymentology are the closest like-for-like options.

Choose Marqeta if you need real-time funding logic and want one vendor for processing plus programme management.

3. Paymentology

Paymentology is a London-based issuer processor that raised $175 million in May 2026 to expand into credit, tokenisation and stablecoin services (Fintech Futures).

Choose Paymentology if you plan a programme across several markets and want a processor with global reach.

Choose Edenred Payment Solutions if you want an established issuer with a long UK track record and in-house processing.

Modulr is a UK embedded payments platform with an FCA-authorised EMI and an EU EMI in the Netherlands. It became a principal issuing member of Mastercard in 2020. It issues single-use and multi-currency virtual cards and physical cards, with Apple Pay and Google Pay, and serves 6,000+ businesses.

Choose Modulr if you run a B2B product such as expense management, travel or payroll and need cards next to accounts and payments.

7. Equals (formerly Railsr)

Equals is the combined business of Railsr and Equals Money. The two merged in 2025 and moved to a single Equals brand in June 2026 (Liquidity Finder). It holds FCA EMI and PI authorisations and supports Visa and Mastercard issuing for consumer and corporate cards.

Choose Equals if you need embedded accounts and cards from one UK provider. Check the post-merger roadmap during due diligence.

Best all-in-one card issuing platforms with a card issuing API

All-in-one providers bundle BIN sponsorship, processing and a virtual card issuing API. You launch faster. You give up some control.

Choose Wallester if you want a quick white-label launch and are comfortable with a newer UK licence holder.

Which card issuing providers did we leave out, and why?

• Solaris: discontinued its e-money business in 2024, and its UK subsidiary Contis went into special administration in 2025 (Business Sale).
• Griffin: a UK bank with BaaS, but cards were planned for 2026 and not live when we checked.
• Swan: preparing to enter the UK, not live yet.
• Galileo and Highnote: no UK presence found.

How do you choose the best card issuing platform for your startup?

Start with one question: how much of the card stack do you want to own? The more you own, the more control you get. You also need more people, more compliance work and more time.

Then check these points with every vendor on your shortlist.

1. Who is the BIN sponsor? Know which legal entity holds the scheme membership and the FCA authorisation.
2. How does safeguarding work under CASS 15? Ask how reconciliation data reaches you and in what format.
3. What is the authorisation model? Ask about JIT funding, stand-in processing and response time limits.
4. Which card types are live in the UK today? Many features are live in the US or EU first. Stripe’s consumer issuing, for example, is US-only.
5. What does migration look like? Ask how card tokens and BINs move if you switch provider later. The Railsr and Solaris stories show why this matters.
6. What does it cost? Most UK vendors do not publish pricing. Ask for setup fees, per-card fees, monthly minimums and the interchange share in writing.

Design your integration layer so the processor can be swapped. A thin abstraction between your app and the card provider costs a few extra weeks up front and can save you a painful rebuild if your provider changes ownership.

FAQ

What is a card issuer? A card issuer is the regulated bank or e-money institution that provides a payment card to the cardholder and is responsible for the card account. In fintech programmes, the issuer is usually the BIN sponsor, while the fintech owns the brand and the customer.

What is the difference between an issuer processor and a BIN sponsor? A BIN sponsor is the regulated entity that holds the Visa or Mastercard membership and carries liability. An issuer processor is the technology that authorises transactions and manages cards. Many UK programmes use both.

What is the difference between card issuing and card acquiring? Card issuing serves the cardholder: it provides the card and approves or declines payments. Card acquiring serves the merchant: it accepts card payments and settles the money to the merchant’s account.

Do I need an EMI licence to issue cards in the UK? Not always. Many fintechs launch under a BIN sponsor’s EMI licence as its agent or partner, and apply for their own EMI licence later as they scale. Your sponsor will still expect you to meet Consumer Duty and its own compliance standards.

What are the new safeguarding rules for card issuers in 2026? The FCA’s CASS 15 safeguarding rules for payments and e-money firms came into force on 7 May 2026. They add daily reconciliations, monthly safeguarding returns and, above a threshold, annual audits.

Is Stripe Issuing available in the UK? Yes, for commercial cards. Consumer card issuing on Stripe is available in the US only.

What happened to Railsr? Railsr merged with Equals Money in 2025, and the combined company now operates under the Equals brand.

Conclusion

The best UK card issuing platform depends on how much of the stack you want to own. All-in-one providers get you live fastest. Issuer processors plus a BIN sponsor give you the most control. Programme managers sit in between.
