How to improve your EPC rating

An EPC or Energy Performance Certificate is like the multicoloured stickers you find on new appliances. It lets you know how energy efficient a home is.

Find out more about the benefits of making changes to your home and which improvements could help improve an EPC rating.

 

Where to start

You can do things to improve the energy efficiency rating of your home. Your EPC will give recommendations on how to do this.

You can also watch our video to find out more about how to improve your EPC rating (1 min 42 secs).

You could also think about getting a heat pump which is an energy efficient way of heating your home.​

 

A quick guide on the improvements you can make

There are various changes you can make to your home to keep it warm and energy efficient.
 

Benefits to improving your EPC rating

  • Cheaper energy bills. The more energy efficient your home is, the less you should need to spend to keep your home warm.
  • Increased property value. If you’re selling your home, people may be more inclined to pay more for an energy-efficient home.
  • Earn cashback. Up to £2,000 with our Green Living Reward for eligible customers.

Energy-efficient lighting

Replacing standard light bulbs with energy-efficient ones could be a quick and easy way to improve the energy efficiency of your home. The cost to replace all your lightbulbs will depend on how many you have and the brand you pick.

Hot water cylinder jacket

A hot water cylinder jacket is one of the cheapest ways to improve the energy rating of your home. Ideally, you want a jacket that’s at least 80mm thick. These are available from most DIY stores.

Keep the heat in


Insulating your home is a great way to reduce heat loss and therefore how much money you spend on heating.

There are four key areas of your home you can add insulation to.
 

Floor insulation

Adding insulation below the ground floor of your property helps prevent heat escaping into the ground below. 

Roof or loft insulation

Fairly easy and inexpensive to install, loft installation could make a difference to your bills. 

Wall insulation

Insulating the walls of your home is one of the most common EPC recommendations. 

Updating your windows

Updating single-glazed windows to double glazing could affect your energy rating.

Take control of your home


These simple changes could help you reduce the amount you spend on heating.
 

Heating controls

Having better control over your central heating makes it easier to keep a lid on its use and limit how much it costs you.

Smart meters

Much like improving your heating controls, installing smart meters makes it easier to see how much energy you’re using and how much it’s costing you.

Thermostatic radiator valves

If your boiler is fitted with a flow meter – that detects when all your radiator valves are closed, you can install thermostatic radiator valves (TRVs) on every radiator. This means you can control the temperature of each radiator separately. Helping save energy by only heating the rooms you need.
