New rules on preparing Energy Performance Certificates, or EPCs, have just come into operation. Here's what you need to know about EPCs going forward.
What is an EPC?
An EPC is an Energy Performance Certificate.
EPCs show you how energy efficient a property is using a rating from A (most efficient, lower energy costs) to G (least efficient, higher energy running costs).
EPCs take into account factors such as how well your property is insulated, double glazing, the type of heating and even whether your lighting is energy efficient.
The idea is to help buyers and tenants choose an energy efficient home.
When you need an EPC
By law you need a valid EPC when marketing your home for sale, and also if letting it.
EPCs are valid for 10 years. If yours has expired (or your home never had one), you will need one when you market your home for sale or let.
What are the new rules?
The new rules surround the methodology used by domestic energy assessors – the people who assess homes and prepare EPCs. They came into effect earlier this month.
They involve something called the Reduced Data Standard Assessment Procedure or RdSAP 10.
While these changes are very technical, they mean that, instead of making assumptions, energy assessors will need to make more detailed checks and ask for supporting documents where necessary.
The changes cover assessing your home's insulation, ventilation, double glazing and heating and hot water system, among other things.
The possible impact of the new EPC rules
Some experts believe that the new rules could see some homes put into a different EPC band than previously – either a higher one or a lower one in some cases.
The new rules also involve more work for energy assessors when they prepare an EPC. This could push up the cost of ordering an EPC.
What should I do now?
If you have a current, valid EPC you will not be affected until you need a new one.
If you need a new EPC in order to market your home for sale there will be some changes. But there is nothing to worry about. Your energy assessor will do all the work when they assess your home. Just be ready to help them by providing any information and documents they ask for.
