If you are looking to sell, rent, modify, or build a commercial property in the UK, then you probably need to improve your commercial EPC score.

By law, commercial buildings need an EPC score of “E” or higher. With the government indicating that this low bar will be raised in a few year’s time, and energy efficiency so high on the agenda, many commercial property owners and developers are looking for ways to improve their rating.

What is a Commercial EPC?

A Commercial Energy Performance Certificate (EPC) is a document that provides information about the energy efficiency of a commercial building. It is required by law in the United Kingdom, for certain types of commercial properties when they are constructed, sold, or rented out.

Additionally, a commercial EPC gauges the energy efficiency of a building and gives it a rating from A to G, where A is the most energy-efficient and G is the least. The assessment takes into account factors such as insulation, heating and cooling systems, lighting, and renewable energy sources. The EPC also provides recommendations for improving the energy efficiency of the building, which can help reduce energy costs and environmental impact.

How Can I Improve My Commercial EPC Rating?

Improving your commercial EPC rating involves implementing energy-efficient measures to enhance the energy performance of your building. Here are some steps you can take to improve your commercial EPC rating:

Do all Commercial Buildings Need an EPC?

Not all commercial properties in the UK need an Energy Performance Certificate (EPC). The requirement for a commercial EPC depends upon several factors, including the type of building and its intended use.

In general, the following situations would require a commercial EPC in the UK:

Sale: When a commercial property is being sold, an EPC is required to be provided to potential buyers.

Rent: If a commercial property is being rented out or leased, an EPC must be made available to prospective tenants.

Construction: When a new commercial building is constructed, an EPC is required upon completion.

Modification: If there are significant modifications made to an existing commercial building that would affect its energy performance, an updated EPC might be necessary.

When is an EPC Not Required for Commercial Property?

Specific commercial EPC exemptions include:

Places of worship: Buildings used primarily for worship or religious activities are exempt from the requirement for an EPC.

Temporary buildings: Structures intended to be used for a period of two years or less are exempt from the EPC requirement.

Industrial sites, workshops, and non-residential agricultural buildings: Buildings with low energy demand that are not frequently visited by the public and are primarily used for industrial or agricultural purposes may be exempt from needing an EPC.

Standalone buildings with total useful floor area less than 50 square meters: Small standalone buildings that are not part of a larger complex and have a total useful floor area of less than 50 square meters are exempt.

Buildings scheduled for demolition: Buildings that are due to be demolished within two years of the sale or rental agreement being concluded are exempt from requiring an EPC.

Listed buildings: Buildings officially listed as being of special architectural or historical interest and where compliance with certain energy efficiency requirements would unacceptably alter their character or appearance are exempt from needing an EPC.

It’s important to note that these exemptions may have specific conditions and limitations. We recommend that you review the latest regulations. In addition, you should consult with a qualified professional to determine the applicability of exemptions to a specific commercial building.

What EPC Rating Do I Need to Achieve?

The Minimum Energy Efficiency Standards (MEES) are regulations that set a minimum energy efficiency standard for privately rented non-domestic properties in the United Kingdom. These standards are designed to improve the energy efficiency of buildings and reduce carbon emissions. The MEES regulations apply to both commercial and residential properties that are rented out.

The minimum energy efficiency standard is an EPC rating of “E” or above. This means that properties with an EPC rating of F or G, which are the lowest ratings representing the least energy-efficient buildings, cannot be rented out unless certain exemptions apply. The MEES regulations apply to all privately rented non-domestic properties, including offices, shops, industrial units, and other commercial premises.

MEES Regulation Trigger Points

The MEES regulations for commercial property have different trigger points depending on the circumstances: 

New leases: From April 1, 2018, the MEES regulations applied to new leases, meaning that a property with an EPC rating of F or G could not be leased or re-leased. This, however, is expected to be raised to a C by 2030.

Existing leases: From April 1, 2023, the MEES regulations extended to existing leases as well. This means that properties with an EPC rating of F or G cannot continue to be rented out even if they were leased before April 1, 2018. This is also expected to be raised to a C by 2030.

Exemptions: There are certain exemptions to the MEES regulations, including cases where energy efficiency improvements are not cost-effective, where necessary consents cannot be obtained, or where improvements would result in a devaluation of the property.

Enforcement and Penalties: Local authorities are responsible for enforcing the MEES regulations. Penalties for non-compliance can be substantial, including financial penalties and publication of non-compliant properties.
