Properties purchased since 2007 are required by law to have an energy performance certificate. These certificates are based upon an assessment of the fabric and lighting, heating and hot water systems in place, to establish the efficiency of your property and categorise it into broad bands from A (very efficient) to G (very inefficient). However if you don’t already have a certificate for your property and you are considering renewable technology, Limitless Energy can provide a certificate as part of the assessment and installation process. Alternatively you can commission a green deal domestic energy assessor to provide a certification for you.
