SAP Assessment & EPCs

SAP is the Government's Standard Assessment Procedure for Energy Rating of Dwellings. SAP is adopted by government as part of the UK national methodology for calculation of the energy performance of buildings.

New dwellings need to have a SAP Assessment to demonstrate compliance with the Building Regulations. It measures the energy efficiency of the dwelling and the amount of carbon produced.

In England and Wales new homes must meet a minimum level of energy efficiency. The new SAP assessment considers the thermal performance of the fabric of the building, air leakage, heating and hotwater installations and ventilation.

It is important to consider the energy efficiency of the dwelling early in the design process to avoid having to make costly changes later. The new methodology means that simply checking minimum U-Values for walls, floors and roofs does not guarantee compliance. DJD Construction Consultants can carry out design stage SAP assessments and provide advice on achieving compliance.

SAP assesments have to be carried out by a Registered Person, our Lead SAP Assessor, Kevin Davis, is registered to produce SAP assessments and Energy Performance Certificates (EPCs) for new building dwellings.
