An energy performance certificate (EPC) shows how energy efficient your home is. It also shows you its environmental impact (EIR), and recommends ways you can save energy.

Your home gets an overall rating, using a traffic light system like this one:

A is the most efficient, and G is the least. You probably guessed that already. The average score in England and Wales is 60 (D).

Use your EPC to save money

An EPC gives you practical, personalised recommendations for making your home more efficient – things like energy lights, wall insulation, or double glazing. Home improvements like these can drive down your monthly energy bills and increase the value of your home.

Your EPC gives you an idea of how much each improvement might cost, and the amount of energy and money it could save you. That way, you can make an informed decision about what’s right for you.

Use your EPC to save the planet

The energy we use to heat, light and power our homes makes up around a fifth of the UK’s carbon dioxide emissions. Understanding your EPC doesn’t just help you save money on bills – it can help you do your part for the planet.

How to get an EPC

If you’re buying, it’s always worth checking the property’s EPC. If you’re selling or renting, you need to have an EPC for your home, but your estate or letting agent should sort that for you.
