Domestic Energy Assessment

Domestic Energy Assessment

Stroma Certification provides the training, software, and certification required to become a Domestic Energy Assessor for existing dwelling.

Domestic Energy Assessment (DEA) Certification Scheme

Become a Stroma-certified Domestic Energy Assessor (DEA) and lodge Energy Performance Certificates (EPCs) for existing domestic properties in England, Northern Ireland, Scotland or Wales.

DEAs collect data about a property, including dimensions, construction and services, in order to generate an EPC using Stroma Certification’s user-friendly RdSAP (Reduced data Standard Assessment Procedure) software.

Stroma Certification’s ABBE approved training can help you become a Domestic Energy Assessor. DEA candidates are required to:

  • Submit a portfolio evidencing their business skills and a minimum of five EPCs
  • Undergo a CRB check
  • Provide details of your Professional Indemnity and Public Liability Insurance
  • Complete a minimum of 10 CPD hours (see the Resource Centre for more details)

Certification scheme membership demonstrates that you are able to carry out work competently and to a high standard, and in accordance with the National Occupational Standards (NOS).

Certification is provided free of charge with Stroma Certification with NO membership renewal fees or advance purchase of lodgement credits. All lodgement fees are competitively priced.

Scottish EPCs

All Stroma-certified DEAs may gain the ability to lodge EPCs in Scotland, by carrying out a free, simple CPD module on the Scottish Building Regulations. Stroma Certification is an Approved Protocol Organisation, approved to operate the DEA certification scheme in Scotland.
