On Construction Domestic Energy Assessor (OCDEA) Training

✅ Play a critical role in the drive towards net zero
✅ Work for yourself- control your work/life balance
✅ Complete new build assessment work from your home or office – no site visits required

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.

General numeracy, literacy and computer skills are useful in this role. It also helps to have some background knowledge or experience of construction/building techniques although this is not essential.

Pricing starts at around £90-100 for a small simple dwelling/flat and can generally go up to around £250+ for a large/complex dwelling.

OCDEAs will just need a laptop/pc in order to carry out their assessment work. Specialist software can be used online or installed locally.

Building plans are typically sent electronically so dimensions can be taken in a PDF or CAD reader.

However should you receive paper plans then you will likely need a scale ruler.

For newbuild dwellings, work comes mainly from builders and architects, while for extension calculations the requests often come from homeowners. Work is driven by the requirement to produce EPCs and comply with Part L of the building regulations.

The 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.

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.
