Who can produce a Commercial EPC?

Only an accredited Non-Domestic Energy Assessor (NDEA) can produce a valid Commercial Energy Performance Certificate (EPC). These assessors are trained and approved through government recognised accreditation schemes such as Elmhurst, ECMK or Quidos. Each assessor holds a qualification level that matches the complexity of the building they can assess.

Level 3 assessors handle smaller, simpler buildings with standard heating and ventilation systems. Level 4 assessors work on larger or more complex sites that need detailed modelling, while Level 5 assessors specialise in properties that require advanced dynamic simulation. You need to use an assessor with the right level of qualifications for your building to make sure your Commercial EPC Certificate is accurate and compliant.

Accredited assessors follow strict quality assurance procedures and are insured to carry out the work. Their accreditation number appears on the certificate, so you can check credentials at any time. Working with a qualified professional gives you peace of mind that your EPC meets all legal standards and reflects the true performance of your building.
