The UK’s residential mortgage market, totalling approximately £1.7 trillion in outstanding lending, is one of Europe’s largest, but it is under growing pressure. Since 1982, average first-time buyer incomes have increased sevenfold, while property prices have jumped sixteenfold, contributing to a 22% drop in first-time buyer numbers. Record-high house prices in early 2025 have only added to affordability challenges. First-time buyers are driving market demand, yet legacy systems are struggling to deliver the seamless, mobile-first experiences these borrowers now expect.
This report explores how UK lenders are responding to these shifts by rethinking their core technology. Drawing on industry insight and real-world examples, it shows how cloud-native, composable platforms are enabling mortgage providers to move faster, reduce operational friction and stay compliant, while creating better experiences for borrowers in a changing market.
