UK Scraps New Payments Architecture: What the Rebrand to Interbank Infrastructure Renewal Means for Faster Payments and BACS

The UK government has cancelled the New Payments Architecture procurement and renamed the programme to Interbank Infrastructure Renewal (IIR), marking the most significant strategic pivot in UK retail payment infrastructure since the NPA was first conceived in 2017.

The Payment Systems Regulator has revoked Specific Direction 2 and Specific Direction 2a, which had mandated the NPA programme, and is reconsidering the implications for the SD3 compliance deadline of 1 July 2026. Pay.UK remains responsible for delivering the renewed programme.

Nine Years of the NPA

The NPA was conceived as a wholesale replacement for the UK's ageing interbank clearing infrastructure, consolidating Faster Payments, BACS, and potentially other payment schemes onto a single modern platform. The programme was intended to deliver a new central infrastructure layer with ISO 20022 messaging, enhanced data capabilities, and a more competitive supplier model.

Progress stalled repeatedly. The initial procurement process, managed by Pay.UK, drew criticism for its complexity and pace. Multiple delays pushed timelines further out, and industry confidence in the programme's delivery diminished as costs escalated and scope expanded.

What the Rename Signals

The shift from NPA to IIR is more than cosmetic. The government's conclusion that the programme requires a "more agile and flexible approach" signals a move away from the big-bang replacement model toward incremental modernisation. This aligns with lessons learned from other large-scale infrastructure programmes globally, including the Eurosystem's phased TARGET consolidation.

The revocation of the PSR's Specific Directions removes the regulatory mandate that had compelled industry participation in the NPA. Future delivery under the IIR banner will likely operate under a different governance and procurement framework, though details remain to be defined.

Implications for Faster Payments and BACS

Faster Payments continues to operate on VocaLink infrastructure under existing contracts, while BACS remains the backbone for UK direct debits and bulk credit transfers. Neither system faces an immediate operational risk from the NPA cancellation, but both were slated for eventual replacement under the original programme.

The SD3 compliance deadline of 1 July 2026, which relates to confirmation of payee requirements, is now under review. The PSR has indicated it will consider whether adjustments are needed given the changed programme structure.

For UK payment service providers, the immediate practical impact is limited - existing systems continue to function. The longer-term question is when and how the UK will modernise infrastructure that, in the case of BACS, dates back to the 1960s.
