SAP Calculations (Domestic New Build Part 1LA)

An EPC is created by an accredited assessor by firstly visiting the site to collect information on the age, structure, fabric, type of use, size and the energy using components such as heating, cooling, lighting etc.

The certificates are valid for 10 years and are accompanied by a recommendation report outlying areas of improvement.

The purpose of the certificate and report is to bring to the attention of the new owner or tenant the likely running costs of the premises and the estimated carbon impact.
There are exceptions to Non Domestic EPC requirements.
