Quantum Development Finance has secured a long-term facility of up to £500 million from Goldman Sachs, increasing its total funding capacity from £200 million to £700 million.
The additional funding will allow the SME housebuilding lender to provide larger loans and finance a broader range of property schemes, while retaining its focus on smaller housebuilders.
Quantum said the facility would support lending across the property lifecycle, spanning site acquisition and development through to post-completion stabilisation and investment finance.
WIDER FUNDING RANGE
The lender has expanded into operational real estate over the past 12 months, including Build-to-Rent, purpose-built student accommodation and co-living.
This includes longer-term facilities that allow existing borrowers to move from development finance into stabilisation and investment lending following practical completion.
Quantum, which was founded in London in 2023, provides loans of up to £35 million and has financed the development of 4,000 homes. It passed £1 billion of funding during summer 2026 and currently has 125 live projects.
The lender’s 16-strong team is based in Bermondsey, with its current lending ranging from acquisition facilities to five-year operational real estate loans.
Funds managed by AB CarVal have backed Quantum since its launch. AB CarVal, part of AllianceBernstein’s Private Alternatives business, is both a shareholder and primary funding partner.
Rob Sinclair, principal at AB CarVal, says: “We’ve supported Quantum Development Finance since day one, and this expanded facility represents an important next step in the platform’s growth. Quantum has built a differentiated lending model around deep borrower relationships, disciplined underwriting and the ability to flexibly support clients with agility across the lifecycle of projects.
“The quality of Quantum’s existing loan book is high and the fact that 80% of their borrowers are repeat or direct clients stands out. The expanded funding and product set should allow the team to build on that model and even better serve the needs of UK property developers and investors.”
FUNDING CAPACITY
Oliver Thompson, co-founder and chief executive of Quantum Development Finance, says: “Goldman Sachs’ approval of this facility is a positive signal for the Quantum team as we focus on building an alternative credit platform with bank-level operational rigour.
“It’s also a huge endorsement of the team we’ve built and the discipline we bring to every deal and operational running of the business.
“For our clients and partners, these large and long-term commitments from established funding partners, Goldman Sachs and AB CarVal, are a clear signal that Quantum has the appetite and readiness to keep backing high-quality developers and property investors, at every stage of their journey – whether that is their first scheme with us, or their fifth.”
Quantum was established by Thompson alongside Rebecca Murphy, chief operating officer, and Chris Proud, chief financial officer. The three founders have more than 50 years of property development finance experience between them.
The senior team also includes Richard Hemmings, managing director, who previously spent 19 years at Close Brothers; Chris Dunton, credit director, formerly of UTB; and Sam Hudson, head of portfolio management, who joined from Pluto.
Thompson says: “Broadening our product range to accommodate customers from acquisition to post-completion has always been a key part of our growth strategy and one that complements the deep relationships we have built with our clients over several years.
“At Quantum we’re focused on designing a lending business with our borrowers in mind. The foundations are now in place for the next phase of our fast and sustainable growth plan.”
