Energy Performance Certificate (EPC)

An Energy Performance Certificate (EPC) rates how energy efficient a building is using grades from A to G (with ‘A’ the most efficient grade). A qualified surveyor calculates the energy usage and waste with respect to the space available, which is benchmarked to identify the grade.

Non- domestic buildings must have an EPC if:

  • sold or have space available for rent or is a building under construction and newly completed

  • utilised by the public

  • the total useful floor area is over 500 square meters

EPC Costs:

The cost of an EPC will depend on the size and complexity of the building being assessed. All EPCs are valid for 10 years. ESOS Energy are qualified to carry out EPC surveys and will advise on any remedial or enhancement works to attain energy efficiency.
