Right now, the minimum energy efficiency standard for most privately rented homes in England and Wales is EPC E, unless a valid exemption applies.

The government has confirmed its intention to introduce a higher standard from 1 October 2030. Under the currently planned rules, qualifying privately rented homes will need to reach C on a new fabric performance metric, and C on either a heating system or smart readiness metric, again unless an exemption applies. Full details of the reform have not yet been published.

As things stand, the planned maximum landlord investment requirement will be £10,000 per property, although the government's impact assessment estimates the average spend for properties requiring improvement at around £5,400.

There is also an important opportunity for landlords who act early. A property achieving EPC Energy Efficiency Rating C or above before 1 October 2029 can be treated as meeting the new standard until that EPC expires or is replaced.

So, should landlords panic?

Not yet.

But 2030 is close enough that understanding your properties now could save a great deal of rushed decision making later.

No.

This is one of the most important points to understand, because headlines around “EPC C by 2030” can make it sound as though EPC C is already the legal minimum.

It isn't.

As of August 2026, privately rented homes in England and Wales that fall within the Minimum Energy Efficiency Standards — usually shortened to MEES — generally need to have either an EPC rating of E or above, or a valid registered exemption.

Since 1 April 2020, landlords have generally been unable to continue letting qualifying properties rated F or G unless the property is improved or an exemption applies.

Under the existing system, landlords are not required to spend more than £3,500 including VAT on relevant improvements to reach EPC E. New rules will apply under the planned 2030 standard.
