Energy Performance Certificates for your business premises.​ An Energy Performance Certificate (EPC) rates how energy efficient your building is using grades from A to G (with ‘A’ the most efficient grade).​ You must have an EPC if:

you rent out or sell the premises

a building under construction is finished

there are changes to the number of parts used for separate occupation and these changes involve providing or extending fixed heating, air conditioning or mechanical ventilation systems

​You must display an EPC by fixing it to your commercial building if all these apply:

the total useful floor area is over 500 square meters

the building is frequently visited by the public

an EPC has already been produced for the building’s sale, rental or construction

 All EPCs are valid for 10 years.
