What is an Energy Performance Certificate (EPC)

Energy Performance Certificates (EPCs) offer information on how to make a residential home more energy efficient and reduce carbon dioxide emissions. By law all homes bought, sold or rented require an EPC.

How long does an EPC Last?

The Energy performance certificate (EPC) is currently valid for 10 years for properties. However, it is worth noting that 10 years is a long time and the accuracy of the EPC will diminish over time as the avergae fuel costs change. It has been suggested that the validity period ought to be lowered but currently the EPC is valid for 10 years.

How long does an EPC assessment take?

An EPC takes approximately 30 to 45 minutes for a typical 3 bed house. Complex properties with one or more extensions can take longer and smaller less complex properties may take less time. We allow an hour for any EPC appointment and in most cases this will prove to be sufficient. However, larger properties may require slightly longer.

Is an EPC assessment invasive?

The EPC assessment is a non-invasive survey and therefore there is generally no need to remove or move fixtures. Usually the most intrusive action that the assessor will need to carry out is to access the loft space if applicable to the property.
