What are Energy Performance Certificates?

Much like the multi-coloured sticker on new appliances, EPCs tell you how energy efficient a building is and give it a rating from A (very efficient) to G (inefficient). EPCs let the person who will use the building know how costly it will be to heat and light, and what its carbon dioxide emissions are likely to be.

The EPC will also state what the energy-efficiency rating could be if improvements are made, and highlights cost-effective ways to achieve a better rating. Even if you rent your home, some improvements noted on the EPC may be worth implementing, such as switching to more energy-efficient light bulbs.

Why get an Energy Performance Certificate?

Your property's EPC needs to be available to potential buyers as soon as you start to market your property for sale or rent.You must get an approved Domestic Energy Assessor to produce the EPC.

If you implement any of the energy efficiency reccommendations outlined in your EPC, you may wish to get a fresh EPC done to include these improvements.
