- An Energy Performance Certificate (EPC) is a guide that would-be buyers or tenants get when they look at a property. It shows how efficiently a home uses energy, the cost of running a home and recommendations of how to improve the energy efficiency of the property.
As a general rule, an EPC is required every time a home is put up for sale or rent. So, a newly constructed home will have one, a landlord will need one to show potential tenants, and a seller must have one to show to potential buyers.
Places of worship
Temporary buildings that will be used for less than 2 years
Stand-alone buildings with total useful floor space of less than 50 square meters
Industrial sites, workshops and non-residential agricultural buildings that don’t use a lot of energy
Some buildings that are due to be demolished
Holiday accommodation that’s rented out for less than 4 months a year or is let under a license to occupy
Listed buildings – you should get advice from your local authority conservation officer if the work would alter the building’s character
Residential buildings intended to be used less than 4 months a year
Recommendations on an EPC are the ways to improve energy efficiency and in turn to reduce the energy bills. You are not legally obliged to do the recommendations before you sell a property. But it is advisable to read how it affects while renting a property. And as a landlord from 2020 April 1st, you are legally obliged to make sure that the property has a valid EPC that is rated “E” or above.
If you don’t understand something on your certificate or you disagree with it, the first place to go is the energy assessor that carried out the EPC – their details should be available in the ‘About this document’ section.
But if they can’t resolve your issue, you can contact their accreditation scheme, and the details will also be listed in the same section of the certificate.
An EPC survey is called a “non-invasive survey”. This means our assessors have to follow some conventions and guidelines and have to depend on the evidence that they could only collect from the property.
We depend on the building regulations of the built year of the property and it is the software that implies the term “assumed” on the certificate (based on built year) if we cant find evidence from the property.
The term assumed states that the assessor was not able to find the evidence of insulation and the representation on the certificate is based on the built year regulations.
For loft conversions, we need to have planning permission or completion documents to enter the date of conversion to the EPC. In cases where we are not provided with such documents by the clients, we try to find those documents from the local planning permission web sites. But in cases, we end up with no result. in such cases as per the conventions, we have to date the loft conversion to the built year of the property and built year regulations are applied by the software on the certificate. That is why it comes up uninsulated assumed based on the built year of the property.
For loft insulations, we need to visually identify the insulation thickness to enter it on to the EPC. If the loft is boarded and if the assessor cant visually identifies a minimum of 75% area, an assessor will have to mark the insulation thickness is unknown. And the software will date the loft insulation to the built year of the property and built year regulations are applied by the software on the certificate. That is why it comes up uninsulated assumed based on the built year of the property.
The floor area displayed on the EPC is only the habitable area. For example, unheated porch, garage, separated conservatory, etc won’t be counted in the EPC calculations.
