What is a Commercial EPC?
A 'Commercial' or Non-Domestic Energy Performance Certificate is a certificate that sets out an energy rating for a non-domestic building and contains recommendations on measures for energy efficiency improvement.
Commercial EPCs are rated from A+ (most energy efficient) to G (least energy efficient).
When is a Commercial EPC Required?
Similar to Domestic EPCs, a Commercial EPC is required when a building is sold, rented or built (with some exceptions).
A Commercial EPC may also be required when a building is altered in certain ways.
What Rating Must a Non-Domestic Building Achieve to be Rented?
Under the current regulations, a rating of E or higher must be achieved.
To note, from April 2023, this requirement will be extended to existing rentals.
What are the Future Requirements for Non-Domestic Buildings?
As of writing, the Government are reviewing proposals to increase the minimum threshold to a rating of B by 2030.
It is proposed that a phased approach will be undertaken.
April 2025: Landlords must obtain a valid EPC; then follows a 2 year window for compliance.
April 2027: Landlords must obtain another EPC (unless the existing EPC is a rating of C or above) to demonstrate that the building has been improved to a rating of C (or above) or have achieved the best available rating in accordance with a reasonable view as to cost.
