Commercial EPC Requirements
Understanding when a Commercial EPC is legally required can help avoid delays, compliance issues and unnecessary costs. Whether you're selling a commercial property, granting a new lease, renewing an existing tenancy or preparing a vacant building for the market, these are the most common questions we receive from landlords, property owners, solicitors and commercial agents.

Commercial EPC Rules, Sales, Lettings and Legal Obligations


What are the Current Commercial EPC Requirements?
Most commercial properties in England and Wales require a valid Commercial Energy Performance Certificate (EPC) when they are sold, let, newly constructed or subject to certain lease transactions. The EPC provides an energy efficiency rating from A (most efficient) to G (least efficient) and remains valid for 10 years. Commercial landlords must also consider Minimum Energy Efficiency Standards (MEES). Under current regulations, most commercial properties must achieve a minimum EPC rating of E before they can be legally let, unless a recognised exemption applies. Requirements can vary depending on building type, occupancy status and whether any exemptions apply. If you're unsure whether your building requires an EPC, it is always worth checking before marketing the property or entering into lease negotiations.

When is a Commercial EPC Legally Required?
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 rather than after terms have been agreed. In most cases, the EPC should be commissioned before the property is advertised on the market. Landlords, property owners and commercial agents all have responsibilities to ensure compliance with EPC regulations. While some exemptions exist, most offices, retail units, warehouses, industrial premises and commercial buildings will require a valid EPC during a transaction.

Do I Need a Commercial EPC Before Selling a Commercial Building?
Yes. In most cases, a valid Commercial EPC is required before a commercial building can be marketed for sale. The EPC provides prospective purchasers with information about the building's energy efficiency and forms part of the due diligence process during the transaction. Many solicitors and commercial agents will request confirmation that a valid EPC exists before progressing a sale. If a valid EPC already exists and is less than 10 years old, it can usually be reused provided no significant alterations have been made to the property. Checking the EPC register before commissioning a new assessment may save time and unnecessary expense.

Do I Need a Commercial EPC When Letting Commercial Property?
Yes. A valid Commercial EPC is generally required before a commercial property can be let to a new tenant. The certificate should be made available to prospective tenants and will often form part of the marketing information provided by agents and landlords. In addition to obtaining an EPC, landlords should ensure the property complies with current Minimum Energy Efficiency Standards (MEES). Most commercial properties must achieve an EPC rating of E or above before they can be legally let, unless a valid exemption has been registered. Obtaining an EPC early in the process can help avoid delays once a tenant has been found.

Do I Need a Commercial EPC for a Lease Renewal?
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 as part of the transaction. This is particularly important where the existing certificate has expired or where the property's EPC rating could affect compliance with current MEES regulations. Many landlords only discover that an EPC has expired once lease negotiations are already underway. Checking the status of the certificate early can help prevent delays and ensure the renewal process runs smoothly.

Do Vacant Commercial Properties Require an EPC?
Often, yes. A commercial property does not become automatically exempt from EPC requirements simply because it is vacant. If the building is being marketed for sale or lease, a valid Commercial EPC will usually still be required. The EPC relates to the building itself rather than whether it is currently occupied. Empty offices, warehouses, retail units and industrial premises frequently require an EPC before they can be advertised to prospective buyers or tenants. However, certain exemptions may apply depending on the condition, intended use or future redevelopment plans for the property.

What Happens If I Don't Have a Commercial EPC?
If a Commercial EPC is legally required and one is not provided, the property owner may face enforcement action and financial penalties. Failure to obtain an EPC can also delay sales, lettings and lease transactions. Solicitors, surveyors, lenders and commercial agents often request confirmation that a valid certificate exists before progressing a transaction. In addition to potential penalties, a missing EPC can create unnecessary complications during legal due diligence and may discourage buyers or tenants from proceeding. Obtaining an EPC before marketing a property is usually the simplest and most cost-effective approach.

What is the Penalty for not Having a Commercial EPC?
Where a Commercial EPC is required but has not been obtained, enforcement authorities can issue financial penalties. For commercial properties, penalties are generally linked to the property's rateable value and can range from hundreds to several thousand pounds depending on the circumstances. Importantly, paying a fine does not remove the obligation to obtain the EPC. The certificate will still be required to achieve compliance with the regulations and complete most property transactions. For this reason, arranging an EPC before marketing a commercial property is almost always the simplest solution.
