EPC Residential

What's an EPC?An image of a lightbulb

An Energy Performance Certificate is part of a Home Information Pack.

The requirement for an Energy Performance Certificate has been set by a European Directive which all member states have to implement. The EU found that a significant proportion of energy was being used by commercial and residential properties. Small increases to the energy efficiency in the millions of properties across Europe will result in a significant overall reduction in energy usage.
The Energy Performance Certificate is part of these new measures to improve property efficiency. It will include suggestions to enable homeowners to improve the energy efficiency of the building. This can mean lower energy bills for the occupiers, and could make homes more attractive to potential purchasers.

The Purpose of an EPC

The Energy Performance Certificate is similar to the certificates now provided with domestic appliances such as refrigerators and washing machines.

Its purpose is to record how energy-efficient a property is as a building.

The certificates are commissioned by the seller (or their agent) from an accredited Energy Assessor, who visits the property to collect the relevant data and creates the certificate.
This data includes the date, construction and location of the house and relevant fittings (heating systems, insulation or double glazing, for example).

Energy Performance Certificates tell you how energy efficient a home is on a scale of A-G. The most efficient homes - which should have the lowest fuel bills - are in band A.
The Certificate also tells you on a scale of A-G, about the impact the home has on the environment. Better-rated homes should have less impact through carbon dioxide (CO2) emissions.

The average property in the UK is in bands D-E for both ratings. The Certificate includes recommendations on ways to improve the home's energy efficiency to save you money and help the environment

Most sellers of newly built homes will have to provide a predicted assessment of the energy efficiency of the property, but a full Energy Performance Certificate should be provided to the buyer when the home is completed.

The certificate will also provide contact details for the Energy Savings Trust who can help you find out whether you could be eligible for grants or discounts to help carry out these improvements to your home. It will also list simple ways that changes in behaviour can save you energy and money - without the need for any works.

How long will the assessment take?

The DEA will typically spend about 1 hour at the property, depending on size, and will collect data relating to the energy usage of the house.

What will be inspected?

The inspection is only visual with no drilling or panel removal and no disturbance to the fabric of your home.

The inspection and data collected will typically include the following;
  • The year of property construction
  • Walls and roof construction
  • Signs of wall-cavity insulation
  • Energy-saving "green" devices (such as solar panels, for instance)
  • Number of double glazed windows and when installed
  • Number of open or closed fireplaces
  • Make and model of boiler and the type of flue and fuel used
  • Number of low energy light-bulbs
  • Type of heating system used and controls (wall thermostat etc...)
  • Roof insulation and thickness.
  • Measure the thickness of the hot water cylinder jacket or foam.
  • Check for excessive window area in larger houses and take measurements of conservatories and extensions.
  • Note the number of habitable rooms that are heated.
  • Measure the internal or external areas of the home.
  • Sketch and make notes relating to home and room layout
Do I need to provide any information?
  • At this time it would be helpful to have available any information you may have about your home's heating, double glazing system and any refurbishment works that have added extra insulation because this can be used to help establish your property's energy rating
What is the data used for?

The data collected will be used to produce the EPC and recommendations for improvement. This Certificate will be registered and published on the Landmark website at

Who can access the report?

Only authorised people, such as the seller, will have access to the report which will have a unique identification number for access on the secure website.

This website can also be used to find a Domestic Energy Assessor in your area or to check the credentials and accreditation details of a DEA.
