Thursday 28th May 2026, Bletchley – Quantum Mortgages, the specialist buy‑to‑let lender, 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.
Reflecting exceptional investor confidence, this latest transaction, Bletchley Park Funding 2026‑1, 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.
The deal attracted strong interest from a broad base of institutional investors, highlighting continued demand for high‑quality UK buy‑to‑let mortgage assets and specialist lending platforms. The senior Class A notes achieved final book coverage of 1.6x and priced at SONIA +80bps. Strong appetite from credit funds and banks drove heavy oversubscription across the mezzanine tranches, with Class C and D notes up to 4.5x covered.
This latest transaction builds on Quantum’s established track record in the capital markets, following its inaugural transaction in 2024 and its second securitisation in 2025. The deal was arranged by HSBC as Lead Arranger, alongside Citi and Lloyds Bank as Joint Lead Managers. The transaction was sponsored by global alternative investment manager AB CarVal, Quantum Mortgages’ primary funding partner.
Bletchley Park Funding 2026‑1 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, Chief Executive Officer 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.”
