What do On Construction Domestic Energy Assessors do?
An OCDEA performs energy calculations for new build homes to make sure they comply with national building regulations. This happens at both a design stage and after the property is built. The OCDEA will issue the necessary compliance report and EPC for building control to sign off.
As part of an assessment the OCDEA will work from specifications provided by builders, and use approved government software to calculate the energy efficiency score of the property. This involves analyzing the various construction details of the property.
The process is very consultative, often working with clients to ensure a building meets compliance, and if required, selecting appropriate energy saving measures. The role is completely desk based, with no visits to site.

The OCDEA training takes 3-5 days depending on previous experience. To gain the qualification you will need to complete a portfolio of 5 assessments. Our advice is that these are completed within three months of completing the course but it may take longer (or quicker) depending on the amount of time you are able to devote to it.
On completion of the OCDEA Training, many OCDEAS work independently or for specialist energy/environmental consultancies. Others are employed by builders, architects, local authorities and manufacturers.
Calculating basic compliance with Building Regulations does not require an OCDEA to be accredited, however to issue EPCs and generate building regulation compliance reports the OCDEA will need to join an accreditation scheme.
