What is an Energy Performance Certificate (EPC)?

An EPC provides two key pieces of information:

1) The energy efficiency of a property on a scale from A – G (The most efficient being A and G the least efficient)

2) The environmental impact of a property.

It also provides recommendations and cost effective ways to improve the energy efficiency of a property. The benefit is that, if acted upon, this can mean lower energy bills due to lower energy consumption, and in turn lower carbon emissions.


When is an EPC Required?

By 2009, as part of the Energy Performance of Buildings Directive (EPBD), all buildings in the UK that are constructed, sold, or rented out will be required to have an EPC.

• Landlords must provide an EPC to prospective tenants, the first time the property is let after October 2008. The EPC is valid for 10 years.

Why is an EPC Important?

All EPCs on existing homes are produced using the same methodology. This means that all home owners and occupiers can compare the energy efficiency of different properties – in a similar way to comparing the fuel consumption of different cars.


Asset Rating

The performance of the property is rated in terms of the energy used per square metre of floor area, energy efficiency based on fuel costs and environmental impact based on carbon (CO2) emissions.

The numbered arrows in the Asset Rating display shows the current rating based on the existing energy performance of the property and a potential rating based on the suggested improvements being implemented.

Estimated Energy Use

The estimated energy section shows the estimated energy use, carbon dioxide (CO2) emissions and fuel costs of the dwelling as shown below:

The figures in the table are based on standardised assumptions about occupancy, heating patterns and geographical location. This means that the figures displayed will be different to the actual fuel cost.


Summary of Energy Performance Related Features

The table is broken down into the different elements of the property and displays its current energy efficiency and environmental performance. The descriptions are based on the data that has been collected specific to the property’s thermal and heating elements, which are Very Poor, Poor, Average, Good and Very Good.



The recommendations section lists measures that can improve the asset rating of the property. These are separated into:

The measures are assessed cumulatively in a predetermined order, and are only included if they make a measurable change to the energy efficiency of the building.

This section also displays typical savings per year, and shows the Energy Efficiency and Environmental Impact rating as a result of these improvements.

Finally, there is a description of each recommendation, as well as how it can be used to improve the energy efficiency of the home. It also gives advice as to the application/installation of the recommendation.
