Guide to Energy Performance Certificates

A valid Energy Performance Certificate (EPC) is required before a property can be marketed which will be valid for ten years. It is the property owner’s responsibility to arrange the assessment.

EPCs show how energy efficient the property is, and what changes could be made to improve its energy efficiency. The certificates give each property a rating from A (the most efficient) to G (the least efficient). As well as an assessment of the property’s energy use, the certificates also look at the volume of CO2 emissions.

EPC assessments must be carried out by approved assessors, which are listed on the EPC register an assessment and usually costs between £60 and £120.

Saving money by improving the energy efficiency

The EPC may contain a number of recommendations of how the property’s energy efficiency can be improved. Alongside these recommendations is a typical cost of how much the improvement might cost, and the typical annual saving. These calculations are based on a number of assumptions, including typical energy costs, so should be seen as a guide rather than an exact recommendation.

Tax deductible energy saving improvements for landlords

When making energy saving improvements, up to £1,500 of VAT paid on certain products and their installation can be reclaimed when the landlord submits their tax returns, as part of the Government’s energy saving allowance scheme. For more information, visit


The rules around energy performance are different when it comes to house in multiple occupation (HMOs). If your rental property is three or more stories high, and houses five or more tenants from more than two different families, then you should contact the council’s environmental health department to find out about the specific energy performance requirements.
