If you own or manage a business property in London, a Commercial Energy Performance Certificate (EPC) is a legal requirement before you can sell, lease, or advertise the building in 2026.

Whether it’s an office, shop, warehouse, or mixed-use unit, an EPC helps assess how energy efficient the building is and is required under UK property regulations.

 What Is a Commercial EPC?

A Commercial EPC rates a non-domestic building’s energy efficiency on a scale from:

  • A (most efficient)
    to
  • G (least efficient)

It is based on a technical assessment of:

  • Heating and cooling systems
  • Building insulation
  • Lighting efficiency
  • Air conditioning and ventilation
  • Overall energy consumption

👉 It also provides recommendations to reduce energy usage and running costs.

 Are Commercial EPCs Mandatory in the UK?

Yes. In the United Kingdom, a Commercial EPC is required when:

  • Selling a commercial property
  • Renting or leasing business premises
  • Constructing a new non-domestic building
  • Advertising a property for sale or rent

Without a valid EPC:

  • You may not legally market the property
  • You could face fines or enforcement action
