The Intermediary Mortgage Lenders Association (IMLA) is forecasting continued growth in the UK housing and mortgage markets through 2026 and 2027, with rising lending volumes supported by falling interest rates, improving affordability and easing mortgage regulations.
In its latest report, The new ‘normal’—prospects for 2026 and 2027, IMLA forecasts that gross mortgage lending will increase to £320bn in 2026, rising a further 9% to £350bn in 2027, up from an estimated £288bn in 2025.
House purchase lending is expected to be the main driver of growth, reaching £205bn in 2026 and £225bn in 2027, while remortgaging is forecast to rise to £103bn and £110bn respectively as interest rates fall and affordability improves.
IMLA also expects the recovery in the buy-to-let market to continue. Gross buy-to-let lending is forecast to rise from an estimated £39bn in 2025 to £44bn in 2026 and £48bn in 2027, supported by rising rental yields and increased market churn exacerbated by the Renters Rights Act. Buy-to-let house purchase lending is projected to grow to £12bn in 2026 and £14bn in 2027, as more amateur landlords exit the market, often to be replaced with more professional operators.
The housing market is expected to remain one of the strongest-performing areas of the UK economy, with average house prices forecast to rise by 3.0% in 2026 and 3.1% in 2027, alongside an increase in transactions to 1.25 million and 1.32 million respectively. Mortgage arrears are projected to continue falling over the period, reflecting improved affordability and the completion of the upward repricing of existing mortgage books1.
Despite ongoing market and regulatory change, intermediaries are expected to remain at the heart of mortgage distribution. IMLA forecasts that around 87% of regulated mortgage lending will continue to be conducted via the broker channel across 2026 and 2027.
Kate Davies, executive director of IMLA, said:
“The housing and mortgage markets continue to play a vital role in supporting the wider UK economy, and our forecasts show that they are set to remain a source of resilience and growth through 2026 and 2027. Falling interest rates, rising transaction levels and a recovering buy-to-let market all point to a more positive outlook for lending activity.
“As the market grows and becomes more complex, the importance of intermediary advice is greater than ever. Intermediaries play a crucial role in helping borrowers and landlords navigate affordability, regulation and product choice, while supporting good outcomes across both the owner-occupied and buy-to-let sectors.”
1 Mortgage arrears tend to rise during periods of rapid rate increases, when borrowers are still absorbing higher payments. Once the repricing of existing mortgages is largely complete, payments stabilise, households adjust their finances and lenders’ support measures take effect. That’s why arrears often fall even though interest rates remain higher than before.
