Climate change in the property sector: A cross-market update

Climate change is no longer a distant threat for the UK property sector, it’s a present-day reality, influencing everything from buyer behaviour to professional advice.

Landmark’s latest cross-market research draws on the perspectives of 150 senior property professionals, including 50 estate agents, 50 residential conveyancers, and 50 mortgage lenders, to reveal how the industry is adapting to this new landscape, where climate risk is now a central part of the conversation.

Climate risk moves to the forefront

Over the past year, concern about climate change has become nearly universal among property buyers and professionals. The sector is seeing this shift first-hand. The days when climate risk was a niche topic are over; it’s now a mainstream consideration that can make or break a transaction.

This heightened awareness is having tangible effects. Conveyancers report that buyers are increasingly willing to walk away from deals if climate risk reports raise red flags. The financial implications are significant, with concerns about mortgage approvals and insurance coverage now tied directly to climate-related findings.

What’s driving this change?

The research points to a shift from general uncertainty about climate change to more practical, property-specific concerns. Energy performance remains a top priority, but more regular heatwaves have pushed heat stress up the agenda. Buyers and professionals alike are asking tougher questions about how homes will cope with rising temperatures, and what features, such as, ventilation, insulation, and EV charging points will help future-proof their investments.

Flooding, once the dominant concern, has slipped down the list, replaced by worries about heat, subsidence, and even coastal erosion. This suggests a more nuanced understanding of climate risk, with buyers looking for homes that are resilient to a wider range of environmental challenges.

Professional advice is evolving

As climate events become more frequent and severe, property professionals are adapting their approach. The majority now recommend further due diligence, such as, climate risk reports earlier in the buying process. There’s also a growing trend towards upfront disclosure, with estate agents increasingly confident in discussing climate risks with clients from the outset.

However, the question of who should take responsibility for advising on climate risk remains open. While environmental specialists are still seen as key, more estate agents and conveyancers are stepping up, supported by new best practice guidelines and internal policies. The Law Society’s recent practice note has provided some clarity, but many professionals are still navigating how to put this guidance into practice.

Barriers and opportunities

Despite this progress, the sector faces real challenges. Uncertainty around regulation and a lack of clear client demand are slowing the pace of change. Data gaps, limited training, and the cost of new tools are also barriers that need to be addressed. Yet, there are signs of optimism: more firms are developing and publishing net zero strategies, and consumer demand for sustainable features is rising fast.

The road ahead

Landmark’s latest research makes it clear that the property sector is at a turning point. Climate risk is now a core part of property decisions, and the industry is responding with greater transparency, better advice, and a stronger focus on resilience. The journey isn’t over, there’s still work to do to embed best practice, clarify responsibilities, and support buyers in making informed, future-ready choices.

But as extreme weather becomes the new normal, one thing is certain: the property sector can’t afford to stand still. Those who adapt will be best placed to thrive in a climate-conscious market.
