UK AEMI vs API in 2026: Permissions, Safeguarding and Post-Brexit Market Access
Published:
October 7, 2026
Choosing between AEMI and API starts with what customers will do with their money. This UK AEMI vs API comparison explains how that choice affects the launch budget, customer protection and the markets a business can serve.
Quick Answer: UK AEMI vs API
AEMI allows a UK-regulated firm to issue electronic money and provide payment services. API can supply authorised payment services but cannot issue electronic money. Both are FCA-regulated and subject to safeguarding requirements, while the funds, permissions and business-model requirements differ.

For a UK AEMI vs API decision, start by tracing what happens to the customer’s money. Does the customer buy stored value, or ask you to carry out a payment? The answer shapes the application, the funding needed at launch and the way customer balances must be protected.
A comparison of the United Kingdom’s EMI and PI finds them to be identical. AEMI represents an electronic money issuer whose business actions might also cover payments. API status is of a payment service provider, which in its authorized activities can move money but never create electronic money as part of such permission. This could create a situation where two similar products might need different authorizations.
AEMI licence UK: issuing and redeeming e-money
The AEMI requirements concern events both before and after a balance is spent by a customer. For a prepaid product or wallet, it is necessary to identify whether that balance is legally constituted as e-money. After that, an explanation would be given on its creation and redemption, telling who organizes its emission and how the customers’ money is said to be safe.
API License UK: operation of payments business
The API requirements UK applicants face follow the intended activity.A remittance business, an acquirer and a payment-initiation provider will not submit identical operating plans. Map a transaction from receipt to completion, name the people responsible at each stage and explain the checks they use.
For the UK EMI vs payment institution decision, look behind the screen design and product name. Briefly holding a customer’s money while completing a transfer is not enough, on its own, to turn a payments business into an e-money issuer.
How do the AEMI and API capital requirements compare?
Budget €350,000 to meet the initial AEMI capital requirements. The API capital requirements have three entry bands: €20,000 for transfer alone, €50,000 for payment initiation, and €125,000 for activities listed in Schedule 1(a)–(e). That last band covers, among other activities, obtaining and executing payments. The figures are set out below:
Authorisation

AEMI
E-money issuance
€350,000
API
Money remittance
€20,000
API
Payment initiation
€50,000
API
Schedule 1(a)–(e) remittance favors
€125,000
If the proposed API combines activities across these bands, use the highest relevant entry figure. After authorisation, the ongoing own-funds calculation may call for more. Keep that reserve separate in the budget from the money needed to prepare an application, pay staff and run the business.
Unlike the small SPI and SEMI regimes, AEMIs and APIs do not have the same size-based eligibility ceilings. This gives an authorised business room to grow, but its capital and controls must continue to support the scale of its activities.
When choosing a UK payment institution licence, check that every planned activity fits its scope. Saving on the entry capital achieves little if the resulting permission cannot support the product you intend to launch.
How do AEMI safeguarding and API safeguarding work in 2026?
Guarding protects covered client funds from use by the firm for its own purposes. Additional FCA rules have applied since 7 May 2026. Records, balance checks and reports underpin the protection method. Enterprises also need current info for handling a failure and an independent safeguarding audit when required.
For AEMI safeguarding and API safeguarding, the practical question is how the covered money remains protected. Segregation is one route; qualifying insurance or a comparable guarantee is another. Records need to show what each customer is owed and allow the firm to check that its chosen configuration covers those amounts.
UK AEMI licence 2026: post-Brexit market access
Neither option gives the business an EU passport. An application for a UK AEMI licence 2026, like an request for API status, deals with permit to operate in the UK. A group wishing to serve EEA markets also needs to consider the local regulatory position and may require a separately authorised entity there. For jurisdiction planning, our Best EMI License Jurisdictions in 2026 guide offers further points for evaluation.
Holding a UK payment institution license does not unlock the EEA market. List the countries you plan to serve, then establish what each part of the group may do there. Build the corporate structure around that estimation.
FAQ
What is the difference between AEMI and API in the UK?
An AEMI can issue e-money; an API cannot. Both routes can support a payments operation, within the scope the FCA has approved. An API license UK businesses obtain does not also make them e-money issuers. Two apps may look alike to a customer while the underlying actions place them in different adjustment categories. Electronic Money Regulations 2011; Payment Services Regulations 2017.
Can an API issue electronic money in the UK?
No. A firm cannot rely on API status to act as an e-money issuer. Calling a product a wallet does not settle its regulatory category. Examine the balance that customers receive: if the arrangement amounts to e-money issuance, a payments-only authorization will not cover that part of the enterprise. FCA PERG 3A.2, guidance on payment institutions wishing to issue e-money.
Can an AEMI provide payment services?
Yes, supplied the payment activities fall within the AEMI’s permissions. The AEMI license UK firms obtain can cover a product that combines stored value with payments. If a separate part of the business handles payments unrelated to that value, assess the PSRs duties for that activity as well. FCA guidance for electronic money establishments and on safeguarding demands.
How much funds is required for a UK AEMI in 2026?
An AEMI needs at least €350,000 in initial capital. Meeting that threshold is part of the application, not the end of the capital obligation. The firm must continue to hold sufficient own fund as its business operates and develops. Electronic Money Regulations 2011, Schedule 2.
What is the minimum capital for a UK API?
An API starts in one of three capital bands: €20,000, €50,000 or €125,000. A remittance-only applicant needs the first amount; a provider initiating payments needs the second. The third applies to the activities listed under Schedule 1(a)–(e). A mixed model must satisfy whichever relevant band is highest. Payment Services Regulations 2017, Schedule 3.
Are AEMIs and APIs required to safeguard customer funds in 2026?
Yes, when they receive or hold relevant funds covered by the safeguarding rules. Safeguarding is intended to protect customer money if the provider becomes insolvent. The firm needs a compliant protection method and records that support the identification and return of customers’ balances. EMRs regulation 20; PSRs regulation 23; FCA CASS 15.
What changed in UK safeguarding rules on 7 May 2026?
The change introduced the FCA’s Supplementary Regime, with more detailed duties for protecting relevant funds. The additional obligations cover reconciliation checks and the records behind them. Monthly returns report the firm’s guarding position, while a resolution pack brings together info needed if the business fails. An independent audit is also needed where the relevant audit provisions apply. FCA PS25/12; CASS 10A and CASS 15; SUP 3A and SUP 16.
UK EMI licence 2026: choosing the right route
An issuer of electronic money needs the AEMI route; a payments-only model points towards API. Test that choice against what customers can actually do with the product. Include the capital reserve, protection of consumer money and geographical reach in the launch budget.
UK EMI requirements 2026 also concern the people and arrangements behind the product. The FCA examines the plan and how it will be run, alongside the funding. For a payments-only business, work through the UK payment licence requirements against each intended action and the controls supporting it.

Make the final choice against a workable operating plan: what will be offered, who will run it and how the business will keep meeting its obligations after launch.
