energy rating chart 201

EPC stands for Energy performance Certificate which must be prepared by a registered assessor only. Energy Performance Certificates (EPCs) are needed whenever a property is:





Your property’s performance is rated in terms of the energy use per square metre of floor area and the energy efficiency based on fuel costs and the environmental impact based on carbon dioxide ( CO2 ) emissions ( your carbon footprint.)

An EPC shows two things. It shows the energy efficiency (i.e. the running costs for the property) and it shows the environmental impact of the property (i.e. carbon dioxide emissions). Each of these is rated A to G with A being the most energy efficient. The A to G Scale is similar to that which is attached to refrigerators. The average rating is likely to be D or E.

The EPC will show the top actions which can be taken to save money/make the property more efficient.

So far as energy efficiency/running costs are concerned there is a standardised way in which these are calculated based on the standard consumption of energy and also it is based on the cost of energy at the time the certificate is issued. It is important to remember this when comparing EPCs for different properties prepared at different dates.
Accompanying the EPC will be a recommendations report with suggested works to be carried out.


  1. Individual house/dwelling (i.e. a self contained property with its own kitchen/bathroom facilities) – one EPC for the dwelling.
  2. Self contained flats (i.e. each behind its own front door with its own kitchen/bathroom facilities) – one EPC per flat.
  3. Shared flats/houses (e.g. a letting of a whole flat or house to students/young professionals etc on a single tenancy agreement) – one EPC for the whole house.
  4. Mixed self contained and non self contained accommodation – one EPC for each self contained flat/unit but no EPC for the remainder of the property.

Property advertisements must contain the asset rating i.e. the EPC rating for the property and the SAP rating were an EPC is available.The requirement for Property Particulars to be accompanied by a copy of the first page of the EPC has been scrapped. However, these must show the EPC rating and the SAP rating for the property if an EPC is available. It is intended that listed buildings and ancient monuments should be excluded from the need for an EPC but it is doubtful that the wording of the relevant exemption achieves this


Once issued the EPC is valid for 10 years (current legislation). It can be used time and time again during this period. You do not have to have a new EPC even if you have work carried out to the property. You can of course obtain a new one after work has been done, if you so wish.

There are fixed penalties for failing to provide an EPC/make one available when required. There is a six month time limit for any enforcement action to be enforced
