If you are involved with any significant planning application, there is a good chance you will need to provide an energy statement. An Energy statement demonstrates how improved energy performance will be achieved. This is over and above that required by the building regulations. When submitting an application it must show consideration of fabric performance, renewable technologies, and efficient and clean building services. If you are ever required to produce an Energy Statement, this will need to be submitted with your planning application. This should sit alongside any other supporting documents.
