New Build Certification

Our specialist team of assessors can provide you with your EPC.

To comply with the EU Energy Performance of Building Directive (EPBD) all new builds (domestic and commercial) are required to have an Energy Performance Certificate on completion.

An EPC is produced from an energy rating calculation using SAP or SBEM software, it demonstrates the energy efficiency of a dwelling upon completion stage and includes recommendations if appropriate, for increasing performance.

Our assessment team has great expertise and will produce an accurate EPC for your new build property and advise on how to achieve Building Regulation Compliance.  All we require from you is a set of scaled plans to start the process.

National Energy Rating are the energy rating industry’s leading supplier of EPCs, when you send us your plans, we can guarantee an accurate prompt service.

Our Energy Rating Process 
Our energy assessor will need to understand the internal layout of the building and for what purposes it is designed to be used. Even if detailed drawings of the building exist it is still likely that a site inspection will be required to confirm the building services and construction details. It is important to understand not only the specific dimensions of the building but also; the actual usage of the space (as this dictates the relative energy usage of each part of the building) and the building services including types of lighting, heating, cooling and ventilation in use in the different areas of a building. All of this information is applied to the modelling software.

The Calculation Procedure
The Government approved software used to model a building and calculate an EPC is provided by the Building Research Establishment and is called iSBEM, the Simplified Building Energy Model. More complex buildings will almost certainly require other dynamic simulation modelling solutions (DSMs) to be used as SBEM cannot currently model complex building elements such as atria, night cooling etc. The SBEM tool has been available for almost two years and complies with Government regulations. Data is entered into SBEM using the iSBEM software interface, this subsequently produces your EPC, recommendations report or Part L compliance calculations.
