Energy Performance Certificates Guide

Why your home needs an Energy Performance Certificate

All buildings within the UK that are available to buy or rent must have an Energy Performance Certificate (EPC). This is to disclose the energy efficiency of the building and to highlight to any future owners or tenants the expected costs involved in heating, cooling and lighting.

All new properties must also get an EPC once they have been built.

EPCs are also beneficial to existing homeowners – an energy performance survey would show you how efficient your home is, and how you can improve the comfort of your home while saving money on your energy bills.

What are EPCs?

Similar to the coloured stickers on electric equipment, an EPC shows the energy efficiency rating of a building. Ranging from an A rating (very efficient) through to a G rating (very inefficient) it will let you know how much you can expect to spend on heating, cooling and lighting the building. It will also tell you if the level of carbon dioxide emissions the building is generating.

An EPC will also include what changes could be made to the building to improve the rating. This valuable information could help save you money whether you rent or you own the building.

A building’s EPC is valid for 10 years, however if you implement the recommended changes to improve the energy efficiency, you may want to get a new rating.

How do you get an EPC?

For properties in England, Wales and Northern Ireland, EPCs can only be produced by accredited Domestic Energy Assessors. Estate agents are able to organise for an assessor to come to your property or you can contact them directly.

For properties in Scotland, only organisations approved by the Scottish Government can complete energy assessments. Visit the Scottish Government’s website for more information.

FIT Tariff qualification

If you are planning on installing solar PV panels and want to benefit from the UK Government’s feed-in tariff (FIT), you will need to get an energy rating for your building. An energy rating of D or above is required before you can receive FITS payments at the standard rate.

Learn from your EPC

When you receive an EPC for a building, it will include suggestions on how you can improve the efficiency rating. Simple changes such as switching to energy efficient LED bulbs or checking the seals around the window and door frames can make a dramatic improvement to the energy efficiency.
