Completion day continues to be one of the most complicated stages of buying a home, according to the partners involved. Property data, legal checks, and payment flows all need to line up across several parties — and when they don’t, the result can be costly delays, added uncertainty, and deals collapsing entirely.
Mastercard is aiming to smooth out this process through a partnership with Pexa, which operates the UK’s only FCA-regulated digital infrastructure for property completions, bringing fund movement and title lodgement together on a single platform.
The approach relies on programmable account-to-account (A2A) payments, which will securely hold buyer funds in reserve and release them automatically once the agreed completion conditions have been satisfied.
The initiative pairs Pexa’s expertise in digital property completion with Mastercard’s payment orchestration capabilities, and is supported by Vocalink — Mastercard’s subsidiary that runs the UK’s A2A payments infrastructure.
Working with Mastercard and Vocalink allows us to explore how synchronised settlement and programmable payments could support consumers, lenders and conveyancers, while advancing our vision for a digitally connected property market where trusted data, digital completion and next-generation payment capabilities work together.

The model will be trialled in Mastercard’s A2A sandbox, building on Pexa’s involvement in the Bank of England’s Synchronisation Lab and its existing partnership with NatWest, with the aim of giving customers faster, more predictable completion timelines.
