On Construction Domestic Energy Assessor (OCDEA) Training

Every newly built domestic dwelling in the UK requires an Energy Performance Certificate (EPC) before being sold or let. As an On Construction Domestic Energy Assessor (OCDEA), you will have the skills and knowledge to complete energy calculations using Standard Assessment Procedure (SAP) software to produce a new build EPC.

The new build market is currently seeing sustained growth reinforced by the government's promise to build a large amount of new homes. 

As a trained and qualified assessor with Elmhurst Energy you will be given the appropriate tools and preparation to go out and produce accurate energy assessments for these new build properties; fully supported by a professional accreditation body.

Success Stories

"First experience of Elmhurst Training. Found it very useful, good trainer at the right pace. I am not familiar with the software, but will look at the trial which has been sent to me. Perhaps a further session on just the software would be useful (for potential newbies!)"
