68% of landlords said renters are prepared to pay more for greener buildings.
This is down from 92% in the previous report.
Richard Winder, head of sustainability at Handelsbanken, said: “Climate change had already become a mainstream commercial consideration for property investors.
“But further energy price shocks, weather extremes and the tumbling cost of clean technologies have only made the case more compelling and urgent.
“Regulations will continue to tighten towards net zero, but it’s market demand that’s accelerating action today.”
Winder added: “Tenants are placing greater value on buildings that are efficient, comfortable and resilient.
“Investors are modelling how their assets will perform over the next decade or more, with the future cost and availability of insurance added into the mix.
“This is all driving rental and valuation outperformance for more sustainable buildings, and we expect this trend to intensify.”
Winder added: “For many landlords, sustainability investment is no longer just about meeting standards. It is about ensuring properties remain competitive, attractive and fit for the future.”
79% of investors with properties in Wales, 78% in Scotland, 76% in the West Midlands and 75% in London said renters are prepared to pay more for greener properties.
