Specialist buy‑to‑let lender, Quantum Mortgages, has completed its third public securitisation as it marks its fourth anniversary since launching, taking funds raised via its Bletchley Park Funding programme beyond £800 million.
The latest transaction was upsized from an initial target of £286 million to a final placement of £297 million. The portfolio is backed by buy-to-let loans originated by Quantum Mortgages, secured against residential properties across England, Wales, and Northern Ireland.
It follows Quantum’s inaugural transaction in 2024 and its second securitisation in 2025.
The securitisation also represents the first UK buy-to-let RMBS to successfully close following the implementation of the Renters’ Rights Act on 1st May 2026.
Jason Neale (pictured), CEO at Quantum Mortgages, said: “This is another important step forward for us. Three securitisations in under two years show we are no longer a new entrant. We are now an established issuer in the capital markets, meaning we can confidently continue providing our intermediary partners with more flexible mortgage options for their clients.
“Investors know and appreciate what they’re getting with Quantum: Consistent origination, disciplined underwriting and assets that perform. The level of demand we’ve seen again underlines confidence in both our platform and the wider UK buy-to-let sector.”
