Energy Performance Certificates (EPCs) give information on how to make your home more energy efficient and reduce your energy costs. All homes bought, sold or rented require an EPC.
EPCs carry ratings that compare the current energy efficiency and estimated costs of energy use with potential figures that your home could achieve. Potential figures are calculated by estimating what the energy efficiency and energy costs could be if energy saving measures were put in place.
The rating measures the energy efficiency of your home using a grade from ‘A’ to ‘G’. An ‘A’ rating is the most efficient, while ‘G’ is the least efficient. The average efficiency grade to date is 'D', and your home will need to acheive this to be eligible for the Feed In Tariff. All homes are measured using the same calculations, so you can compare the energy efficiency of different properties.
EPCs also provide a detailed recommendation report showing how you could reduce the amount of energy you use and your carbon dioxide emissions. The report lists:
· suggested improvements, like fitting loft insulation
· possible cost savings per year, if the improvements are made
· how the recommendations would change the energy efficiency rating of the property
· which improvements may be eligible for funding through the Green Deal (for more information, see ‘The Green Deal’ section further down this page
You don’t have to act on the recommendations in the recommendation report. However, if you decide to do so, it could make your property more attractive for sale or rent by making it more energy efficient.
An EPC is required when a building is built, rented or sold.
A building is defined as a structure with a roof and walls which uses energy to ‘condition an indoor climate’. This means it has heating, air conditioning or mechanical ventilation.
The building can either be a whole building or part of a building that has been designed or altered to be used separately. If a building is made up of separate units, each with its own heating system, each unit will need an EPC.
