What is the value of improving your homes EPC rating?

An Energy Performance Certificate (EPC) gives your home a rating (or score) from G to A, with G being the worst and A being the best. Every property must have one of these if it is sold or rented as they are a legal requirement and give potential buyers and tenants a guide on how energy efficient a property is.

Does a better EPC rating increase the value of your home?

According to research by Moneysupermarket.com, homeowners can boost the price of their property by as much as £24,000 by increasing their EPC rating. Going into more detail, the research suggested that moving from G to F could improve your property value by 6% and going from G to A could increase it by 14%:

What are the most efficient ways to improve your EPC rating?

Below are common methods undertaken by homeowners to improve the energy efficiency of their home. If you want specific advice about your home, you can start by reviewing your existing EPC if you have one. This will list methods to improve your rating.

  1. Insulate your home
    There are many different types of insulation, from loft through to cavity wall insulation. It’s best to speak to an expert who will advice you at no cost. We offer this service, as do many others. If you’d like our opinion, please call us on 01482 588591.
  2. Use energy efficient light bulbs
    You can purchase LED bulbs for under £3-5 each and they can dramatically reduce your energy bill and make your home more efficient. This is one of the cheapest ways to improve the efficiency of your home.
  3. Upgrade your boiler
    This is one the most expensive item on the list, but sometimes it is necessary if you want to make a big improvement to your energy rating. When factoring in the potential increase in house value, replacing your boiler could be a very sensible investment.
  4. Draught proofing
    Controlling the ventilation of your home is important and so is keeping out draughts. Draughts let out the warm air in your home, which makes your heating source work harder. Draught-proofing isn’t an overly expensive job, but it is recommended you seek professional help as you do not want to unsettle your controlled ventilation, as it could lead to damp issues.

There are many more ways you can improve the energy efficiency of your home, especially if you are not particularly interested in improving the EPC rating. Read our handy guide on the easiest ways to heat your home for more information.

How is an EPC rating calculated?

Every house that is listed for sale or to rent will have one of the following charts for you to review. ‘Current’ is self-explanatory, but ‘potential’ is what the assessor believes the house could achieve with work, which could be draught proofing, heat insulation or a new boiler.
