To sell or rent homes in the UK, it is mandatory to have an Energy Performance Certificate (EPC). How can you make homes more energy efficient and thus save on the energy bills ? There are several steps you can take.

If you’re looking to sell or rent your home in the UK, it needs to have an Energy Performance Certificate – or EPC.

An EPC tells you how energy efficient your home is, giving it a rating from A (very efficient) to G (inefficient), as well as recommendations on how to improve it. An EPC includes information on what the energy efficiency rating could be if you made the recommended improvements and highlights cost effective ways to achieve a better rating.


Why should you improve the Energy Performance Certificate (EPC) rating of your home ?

Properties with higher EPC ratings are generally more attractive to potential home buyers or renters ; the more energy efficient a home is, the less it will cost to heat and light.

If you have some money to invest in improving the energy efficiency of your home, the best place to start is by looking at the recommendations on its Energy Performance Certificate. Even if you rent, you could still implement some improvements noted on the EPC, such as switching to more energy efficient light bulbs.

In this guide, we run through the top EPC recommendations to help you understand how much you could save on your energy bills by making changes to your home.


Internal or external wall insulation

One of the most common recommendations on an EPC is to install wall insulation. Given that around one third of all the heat lost in an uninsulated home escapes through the walls, it’s a good place to start.

Most homes in the UK have cavity walls, and the gap can be filled with insulation. We estimate that insulating your cavity walls could save you around £285 a year on your energy bills. If you have solid walls, these can be insulated from the inside or outside of your home. While costs and savings vary, we estimate a semi-detached house could save around £390 a year after installing solid wall insulation.


Floor insulation

Insulating your ground floor if you live in a house, bungalow or ground floor flat is another great way to save money on your heating bills and improve your EPC rating.

Insulating under the floorboards could save you around £75 a year in an average property, or up to £130 if you live in a detached house. If you’re looking for a quick fix, you can seal the gaps between floors and skirting boards to reduce draughts yourself, using a tube of sealant bought from any DIY store.


Loft insulation

Unless you live in a mid-floor flat, heat will escape from your home through the roof. While most homes have at least some loft insulation, often it’s not enough. Topping up from 120mm to at least 270mm of insulation will help – and it’ll save you around £25 each year on your bills. What’s more, if your loft is easy to access and has no damp or condensation problems, it should be easy to insulate – and in many cases, it’s possible to do it yourself.


Low energy lighting

Upgrading the lighting in your home is a quick win for every property’s EPC, if you haven’t already done so. If an average house replaced traditional and halogen lightbulbs with energy efficient LEDs, it would cost around £90 and should save £55 a year.
