Buy-side brief
The UK Small PI in one paragraph
The UK Small Payment Institution sits one step below the Authorised Payment Institution. It is registered, not authorised, by the Financial Conduct Authority under regulations 13 to 15 of the Payment Services Regulations 2017, and it carries a hard eligibility ceiling: the firm’s monthly average payment-transaction volumes over the previous twelve months must remain under EUR 3 million (PSRs 2017 reg. 14(2)). In return for the lighter regulatory load, the registration carves out account information services and payment initiation services. Cadena Brokers represents acquirers, exclusively, pairing them with vetted UK small-PI registrants whose FCA standing, AML programme and banking lines have already cleared diligence.
Why the UK
Why the UK Small PI route
The Financial Conduct Authority registers small payment institutions under regulations 13, 14 and 15 of the Payment Services Regulations 2017. The category exists to give smaller payments operators a proportionate path: applicants whose monthly average payment-transaction volumes over the preceding twelve months stay under EUR 3 million qualify for registration rather than full authorisation. The FCA still tests the fitness and propriety of qualifying-holding shareholders (reg. 14(6)), the programme of operations, the AML controls and the management governance, but it does not impose the prudential and safeguarding burden that sits on authorised firms.
The UK is no longer an EU passport jurisdiction, and small PIs were never passportable in any case. What the registration buys you is direct access to the second-largest payments economy in Europe, with retail acceptance rails, BACS and Faster Payments connectivity through indirect access providers, and a deep pool of EMI and PI clearing partners. Acquirers typically use a UK small PI as a remittance corridor, a B2B treasury vehicle, or a holding pattern for a later upgrade to full authorisation when transaction volumes approach the ceiling.
Permitted scope
What a Small PI registration permits
Permitted services map to paragraphs 1 to 6 of Schedule 1 of the PSRs 2017: cash placement and withdrawal, execution of direct debits and credit transfers, issuance and acquiring of payment instruments, money remittance. Account information services (AIS) and payment initiation services (PIS) are carved out by regulation 14(4) and reserved to authorised firms. If the buy-side thesis depends on offering open-banking AIS or PIS overlays, the small PI is the wrong wrapper, and the API regime is the right one. Treat small PI as a money-movement registration, not an open-banking licence.
One piece of recent regulatory colour matters here. The FCA’s Supplementary Safeguarding Regime, set out in Policy Statement PS25/12 and in force from 7 May 2026, introduces daily reconciliation, resolution-pack and annual-audit obligations on authorised PIs, AEMIs, SEMIs and credit unions issuing e-money. Small PIs sit outside that perimeter. For an acquirer who wants the FCA badge without the safeguarding overhead, the divergence has commercial weight. The trade-off is the EUR 3 million monthly-volume ceiling and the AIS/PIS exclusion, both of which need to be priced into the acquisition thesis at the term-sheet stage rather than discovered later.
The book
What we broker here
Cadena’s UK small-PI book is described generically at the public-page level. Each entity carries a clean FCA register record (no enforcement, no skilled-persons review under section 166 of FSMA), a verifiable AML/CFT programme aligned with the Money Laundering Regulations 2017 and JMLSG guidance, and at least one functional GBP banking relationship that has survived the bank’s most recent periodic review. We pre-vet ultimate beneficial owners, sanctions exposure, source-of-wealth narratives and litigation history before an entity reaches an acquirer’s desk. Profile-level detail is shared on first contact; full data rooms open after a non-disclosure agreement and a buy-side mandate letter are in place.
The diligence gates that matter for a UK small-PI acquisition reduce to three. FCA register continuity, meaning no lapses, no pending variations of permission, no live supervisory correspondence that the acquirer would inherit. Banking continuity, meaning either the acquirer’s KYC pack satisfies the incumbent bank or a replacement bank is lined up before close. AML programme transferability, meaning policies, training records, MLRO arrangements and transaction-monitoring rule sets hold up after change of control. Cost overruns at close almost always trace back to one of these three. We screen for them before we put an entity in front of you.
Acquisition
Acquisition process
The Cadena process for a UK small-PI deal follows the standard four-step path described on the homepage: acquirer brief, profile shortlist under NDA, full diligence supported by our compliance counsel, and signing-to-close coordination. See /#process for the procedural detail. Expedited closings are the norm for entities that pass the three diligence gates without remediation. Where remediation is needed (for instance, an outdated AML risk assessment or an MLRO transition that the bank wants visibility on), we identify it before signing rather than at close, and price it into the term sheet.
Why us
Why work with Cadena Brokers
- Single-side mandate. We act for the acquirer only. There is no split fee, no dual-agency conflict, and no temptation on our side to push a marginal seller across the line. Our fee is paid by you and is tied to the deal closing on terms you accept.
- Pre-vetted compliance and banking. Every UK small PI in our book has been through FCA register review, AML programme review and banking-relationship review before we offer it. You inherit that work rather than repeating it from scratch.
- Acquirer-focused diligence. Our compliance counsel walks you through the qualifying-holding notification under PSRs 2017 reg. 14(6), the AML controlled-function transition, and the bank’s internal change-of-control review. Where the bank wants more, we surface it before signing.
FAQ
Frequently asked questions
What is a UK Small Payment Institution (SPI)?
A UK Small Payment Institution is a payment-services firm registered (not authorised) by the Financial Conduct Authority under regulations 13 to 15 of the Payment Services Regulations 2017. Eligibility is gated by a turnover test: the monthly average of the firm’s payment-transaction volumes over the previous twelve months must not exceed EUR 3 million. A small PI may carry on most payment-services activities listed in Schedule 1 of the PSRs, with the AIS and PIS carve-outs noted below. The category exists to give smaller payments operators a proportionate path that does not require the full prudential and safeguarding load of authorised PI status.
Is an SPI registration the same as an Authorised Payment Institution licence?
No. An Authorised Payment Institution is fully authorised, can serve the entire range of payment services including AIS and PIS, has no turnover ceiling, and faces the FCA’s full safeguarding regime including the new Supplementary Safeguarding rules from 7 May 2026. A Small PI is registered, capped at EUR 3 million in monthly volumes, prohibited from AIS and PIS, and outside the scope of the FCA’s daily-reconciliation safeguarding obligations. Acquirers usually choose between the two on the basis of intended transaction volumes, the open-banking question, and tolerance for ongoing prudential reporting. Both badges sit on the FCA register; the difference is regulatory weight.
Can a UK Small PI provide account information or payment initiation services?
No. Regulation 14(4) of the PSRs 2017 explicitly bars small payment institutions from providing AIS or PIS. Those services are reserved to authorised firms. If the acquisition thesis depends on open-banking propositions (bank-data aggregation, payment initiation overlays, account-to-account checkout), the acquirer should be looking at the Authorised Payment Institution route, not the small-PI route. We broker both.
Do small payment institutions have to safeguard customer funds?
The PSRs 2017 do not impose the statutory safeguarding obligation on small PIs that they impose on authorised PIs (that obligation lives in regulation 23 and applies to authorised firms). The FCA’s new Supplementary Safeguarding Regime, in force from 7 May 2026 under PS25/12, likewise applies to authorised PIs, AEMIs, SEMIs and credit unions issuing e-money rather than to small PIs. That said, well-run small PIs in our book voluntarily segregate client funds in line with FCA expectations, and bank counterparties increasingly require it as a matter of contract.
Can a UK Small Payment Institution passport into the EU?
No. Small PIs were never passportable under PSD2, even before Brexit, and after the UK’s withdrawal from the single market no UK payments licence (small PI, API, AEMI or SEMI) confers EU passporting rights. Acquirers seeking pan-EU coverage should pair a UK small PI with a separate EU-licensed entity. We broker both sides; see our coverage page and the UK API and UK AEMI pages for adjacent routes.
