Energy efficiency remains firmly on the agenda for the property sector, and whilst the pace of reform has shifted in recent years, the direction of travel is clear. Landlords, developers and investors are facing increasing pressure to understand how future energy efficiency requirements could affect their properties and portfolios.
Current Minimum Energy Efficiency Standards (MEES) prevent landlords from letting most commercial properties with an EPC rating below E unless an exemption applies. Whilst proposals to increase minimum standards have not yet been implemented, many in the market expect energy performance requirements to remain a key area of focus for future regulation.
Why should property owners be paying attention?
For many years, EPCs were largely viewed as a compliance issue. Today, they are becoming increasingly important from both a legal and commercial perspective.
A property’s energy performance can affect:
Increasingly, investors, lenders and occupiers are looking beyond current compliance and considering how assets may perform against future standards.
Key legal considerations for landlords
Do your leases allow improvement works?
One of the most common issues landlords face is ensuring they have sufficient rights to carry out works aimed at improving energy efficiency.
Questions worth considering include:
Older leases often contain limited access rights and may not have been drafted with sustainability upgrades in mind.
Can improvement costs be recovered?
Many landlords assume the cost of energy efficiency improvements can be passed through the service charge. However, this is not always the case.
Careful consideration should be given to:
The position will vary from lease to lease.
Are tenant alterations adequately controlled?
Alterations carried out by tenants can affect a building’s energy performance.
Landlords may wish to review whether existing lease provisions provide sufficient control over alterations which could negatively impact EPC ratings or future compliance requirements.
What should developers and investors be considering?
For investors and developers, energy efficiency should form part of the wider due diligence process.
Before acquiring or developing an asset, key considerations may include:
For older building stock in particular, any future tightening of energy efficiency requirements could have cost and asset management implications.
What should property owners do now?
Whilst future regulatory changes remain uncertain, practical steps can be taken now:
Conclusion
The detail of future EPC reform may still be evolving, but energy performance is becoming an increasingly important legal and commercial consideration.
For property owners, the priority should be ensuring that portfolios, lease structures and asset management strategies are capable of responding to future change. Taking stock now is likely to put landlords and investors in a far stronger position if and when further reforms are introduced.
