Non-Domestic Energy Assessor (NDEA) Training

Train to promote non-domestic energy efficiency

Stroma Certification is an approved protocol organisation in Scotland and we offer a CPD course to allow certified NDEAs to lodge EPCs in Scotland. Our NDEA certification scheme also includes an introductory module on the Scottish Building Regulations.

Established NDEAs can benefit from the Energy Savings Opportunity Scheme. Stroma Certification’s ESOS training is a two-day course allowing applicants to be listed on our approved ESOS register and offer energy assessment services to UK businesses.
