Most landlords ‘unaware they’re legally required to have an EPC’
September 8th 2025A new report by The Mortgage Works reveals a striking lack of awareness among UK landlords about energy efficiency rules – with 62% unaware that having an Energy Performance Certificate (EPC) is a legal requirement for rental properties.
Laura Murphy, Paralegal in our Dispute Resolution team provides an update.
This widespread knowledge gap could undermine the government’s ambition to make the rental sector greener, with new minimum energy standards due to take effect in the coming years.
An EPC is a document that rates the energy efficiency of a property from A (most efficient) to G (least efficient) and includes recommendations for improvements.
Under current rules, landlords in England and Wales must ensure their properties meet at least an EPC-E rating, and proposals under government consultation could raise that to EPC-C for all rentals by 2030.
However, The Mortgage Works’ survey of 1,000 landlords shows that only 33% knew about the proposed EPC-C requirement, and 73% were unaware of when the changes are due. Many may take no action until it’s too late.
This lack of understanding is already shaping landlord behaviour. While 45% of landlords with poorly rated properties say they plan to improve them, 28% plan to sell instead. Over half say they won’t act until the regulations become law.
The research also highlights the need for clearer guidance and support:
- 55% would value help in identifying cost-effective energy upgrades.
- 50% want clearer signposting to grants and finance options.
- 63% don’t know how much upgrades might cost.
The Mortgage Works is urging the government to introduce changes gradually and to support landlords with more time, better guidance, and a more flexible approach to improvement costs.
Dan Clinton, Head of Buy to Let at The Mortgage Works, said: “Our research shows limited landlord awareness with some looking to exit the market. Improving energy efficiency is important, but the significant logistical and financial challenges of upgrading 2.5 million properties must be acknowledged.
“Landlords need clear guidance, adequate support, and sufficient time to make their properties greener.”
