Question 1

What is a Commercial EPC?

Accepted Answer

A Commercial Energy Performance Certificate (EPC) is an official document that measures the energy efficiency of a non-domestic building, rated from A (most efficient) to G (least efficient). It is required when most commercial properties are sold, rented or newly constructed, and remains valid for 10 years.

Question 2

Who needs a Commercial EPC?

Accepted Answer

Most commercial property owners and landlords need a Commercial EPC when selling, renting or constructing a commercial building. This includes offices, shops, warehouses, industrial units, restaurants, medical facilities and mixed-use developments. Some exemptions apply for specific building types.

Question 3

How long is a Commercial EPC valid for?

Accepted Answer

A Commercial EPC remains valid for 10 years from the date it is lodged on the national register. It can be reused for sales, lettings and lease renewals during this period, provided no significant alterations have been made to the building.

Question 4

How much does a Commercial EPC cost?

Accepted Answer

The cost of a Commercial EPC depends on the size, complexity and use of the building. At Certus Commercial, prices start from £185 with fixed quotations and no hidden fees. Providing floor plans can often reduce both cost and survey time.

Question 5

How long does a Commercial EPC survey take?

Accepted Answer

A small office or retail unit may take as little as 30 to 60 minutes to inspect. Larger offices, warehouses and multi-storey commercial buildings can take several hours depending on their layout and installed services.

Question 6

How quickly can I receive my Commercial EPC certificate?

Accepted Answer

In most cases a Commercial EPC can be produced and issued within 2 working days of the site survey. Urgent assessments can often be prioritised where a transaction deadline applies.

Question 7

When is a Commercial EPC legally required?

Accepted Answer

A Commercial EPC is legally required whenever a commercial property is sold, rented, newly built or marketed for sale or lease. The certificate should be available to prospective buyers or tenants at the earliest opportunity, before terms are agreed.

Question 8

Do I need a Commercial EPC before selling a commercial building?

Accepted Answer

Yes. In most cases a valid Commercial EPC is required before a commercial building can be marketed for sale. Many solicitors and commercial agents will request confirmation that a valid EPC exists before progressing a sale.

Question 9

Do I need a Commercial EPC when letting commercial property?

Accepted Answer

Yes. A valid Commercial EPC is generally required before a commercial property can be let to a new tenant. Landlords must also ensure the property meets current Minimum Energy Efficiency Standards (MEES), requiring a minimum EPC rating of E.

Question 10

Do I need a Commercial EPC for a lease renewal?

Accepted Answer

In many cases yes. A lease renewal is often treated similarly to the granting of a new tenancy, meaning a valid Commercial EPC may be required, particularly where the existing certificate has expired or where MEES compliance is relevant.

Question 11

What is the penalty for not having a Commercial EPC?

Accepted Answer

Where a Commercial EPC is required but not obtained, enforcement authorities can issue financial penalties linked to the property's rateable value, potentially ranging from hundreds to several thousand pounds. Paying a fine does not remove the obligation to obtain the EPC.

Question 12

What is the minimum EPC rating for commercial property?

Accepted Answer

Under current MEES regulations, most commercial properties must achieve a minimum EPC rating of E before they can be legally let. Properties rated F or G are generally sub-standard and may not be legally lettable unless a valid exemption has been registered.

Question 13

What is MEES for commercial property?

Accepted Answer

MEES stands for Minimum Energy Efficiency Standards. These regulations set the minimum EPC rating that most rented commercial properties must achieve before they can be legally let. The current minimum standard is an EPC rating of E.

Question 14

What are the proposed EPC C and EPC B requirements for commercial property?

Accepted Answer

The government has previously consulted on proposals requiring many commercial properties to achieve EPC C by 2027 and EPC B by 2030. While not yet fully implemented, these proposals indicate the direction of future energy efficiency regulations and many landlords are already reviewing their portfolios.

Question 15

What is the difference between a Level 3 and Level 4 Commercial EPC?

Accepted Answer

A Level 3 Commercial EPC covers simpler buildings such as small offices, retail units and basic warehouses. A Level 4 Commercial EPC is required for more complex buildings with air conditioning, multiple heating zones or advanced ventilation systems, such as banks, medical centres and larger offices.

Question 16

Can floor plans reduce the cost of a Commercial EPC?

Accepted Answer

Yes. Providing accurate floor plans can reduce both the cost and turnaround time of a Commercial EPC assessment. The assessor can review the building layout before attending site, reducing time spent measuring during the survey.

Question 17

Which commercial buildings are exempt from EPC requirements?

Accepted Answer

Some buildings may be exempt, including places of worship, temporary buildings intended for use of less than two years, certain agricultural buildings with very low energy demand, and buildings scheduled for demolition where specific conditions are met. Exemptions are more limited than many property owners assume.

Question 18

Are listed commercial buildings exempt from EPC regulations?

Accepted Answer

Not automatically. Listing status alone does not remove the requirement for a Commercial EPC. Many listed offices, retail premises and commercial properties still require an EPC when sold or let. Whether an exemption applies depends on the specific circumstances of the property.

Question 19

How do I find a Commercial EPC on the register?

Accepted Answer

Commercial EPCs are stored on the government's national EPC register. You can search by address or postcode at find-energy-certificate.service.gov.uk to check whether a valid certificate exists, view the rating, and download the Recommendation Report.

Question 20

Who can carry out a Commercial EPC assessment?

Accepted Answer

Only an accredited Non-Domestic Energy Assessor (NDEA) can produce and lodge a valid Commercial EPC. The assessor must belong to an approved accreditation scheme such as Elmhurst Energy and use government-approved software to calculate the building's energy performance rating.
