Lawyers handling commercial property deals are seeing the ESG setting shift from a checklist item to a core part of risk assessment and investment strategy, especially as new rules on building performance take shape.
Government reforms push EPC data forward
In March 2026 the UK Government released a partial response to its consultation on Energy Performance of Buildings reform. The document says the upcoming rules will require a new generation of certificates that give clearer insight into how buildings use energy. The aim is to line up measurement standards with the country’s Net Zero goals.
One practical outcome is the plan to make certificate information available earlier in the marketing cycle. Prospective buyers, tenants and investors will see key performance data before they sign any agreements. This early access could cut the time spent uncovering hidden issues later on.
Climate due diligence moves into the mainstream
Research within the sector shows climate risk data is now treated as equally important as traditional financial checks. Professionals are looking at both physical threats—like flooding, heat stress, wildfires and subsidence—and transition risks tied to policy changes.

Investors are demanding proof that assets can withstand a changing climate, and they see poor performance as a potential liability. Buildings that lag on energy efficiency may face higher vacancy rates, larger capital outlays and lower resale values.
Because of that, many firms are shifting from a one‑off due‑diligence model to continuous monitoring. Energy use, exposure to climate events and decarbonisation pathways are being tracked across whole portfolios, not just at the point of sale.
In practice, this means lawyers must advise clients on ongoing reporting obligations and on how to embed sustainability metrics into lease terms and financing covenants.
While the shift brings new responsibilities, it also offers opportunities for advisers who can handle the growing data requirements and help clients meet investor expectations.

One observation: the move toward earlier data disclosure could pressure sellers to upgrade assets sooner, potentially reshaping market trends in ways that are still hard to predict.
From a broader perspective, the integration of climate considerations into everyday legal work mirrors the increasing financial materiality of sustainability. As regulators tighten standards, the line between legal advice and strategic business planning blurs, demanding a more interdisciplinary skill set from property lawyers.
Clients are also looking for clear governance frameworks that outline who is responsible for gathering and verifying data. Robust processes can reduce the risk of disputes over undisclosed issues and support smoother transactions.
The upcoming EPC reforms, combined with heightened investor scrutiny, suggest that the era of late‑stage environmental surprise is ending. Lawyers who stay ahead of these changes will be better positioned to guide their clients through the evolving risk setting.
