An EPC (Energy Performance Certificate) is an official document which indicates the overall energy efficiency of your property. It follows a similar method to a domestic appliance such as a fridge or television set. The EPC’s job is to show a potential buyer how efficient your property is at heating itself to a comfortable temperature and to provide adequate light.
The result of the EPC will be an overall rating for your property. ‘A’ is outstanding whilst ‘G’ suggests there are some significant weaknesses.
The EPC is calculated by taking a series of measurements from your property and evaluating the equipment used to light and heat your rooms/water. Here is some of the information that’s taken into account:
- Age and efficiency of your water boiler
- Type of room heating and controls used e.g. room thermostat
- Type of windows and doors
- Loft and wall insulation
- Building construction
- Floor space and ceiling height
- Types of lighting in place
All this information is entered into software called RDSAP which automatically calculates an overall rating, based on a series of calculations it makes.
The EPC will also provide a series of recommendations on how your can make your property more energy efficient, such as floor insulation, solar panels or replacing lighting with modern LED/Flourescent units.
It is a LEGAL REQUIREMENT to have an accurate EPC in place before you can put your property on the market.
An EPC lasts for 10 years, so you will need to renew your EPC if it was done over 10 years ago
