DEA Certification

DOMESTIC ENERGY ASSESSMENT CERTIFICATION (DEA)




Stroma Certification’s DCLG authorised DEA Certification Scheme is the largest certification scheme in the UK for Domestic Energy Assessors. DEA Certification allows an energy assessor to lodge Energy Performance Certificates (EPCs) for existing domestic properties in England, Northern Ireland, Scotland or Wales. By undergoing DEA Certification you can demonstrate to a homeowner that you are able to carry out work competently and to a high standard, and in accordance with the National Occupational Standards (NOS).

Stroma Certification has been the market leader in DEA Certification for a number of years with more than half of UK energy assessors making lodgements using our RdSAP approved software.

Annual Certification £0. EPC & EPR Lodgement Fee £4.51.
Landmark Fee £2.07 (E&W and NI registers) EST Register Fee £1.15 (Scotland ONLY)

Lodgement fees are charged per lodgement. Your total lodgement fee will be the EPC/EPR fee plus the Landmark/EST fee. Fees depend on volume – please enquire to secure the best rates for your business. Landmark and EST Register fees are set by Government and are subject to change. All prices exclude VAT.


What is the DEA Certification Scheme?

Stroma Certification’s DEA Certification scheme is approved by the Department for Communities and Local Government (DCLG). It provides certification for Domestic Energy Assessors to carry out energy assessments for existing domestic buildings. It is the responsibility of the DEA to collect data on aspects of the property such as construction, heating and hot water using the Reduced Data Standard Assessment Procedure (RdSAP). This allows for an EPC to be produced.


Why join our DEA Certification Scheme?

We don’t charge an annual certification fee to DEAs and pledge to keep our lodgement fees extremely competitive. Our RdSAP software is produced in-house and is informed by our expertise in the energy and construction industries to ensure our DEA members have the right tools and information to perform their jobs to the highest standard for homeowners.

Stroma Certification is one of the only certification bodies to offer TrustMark membership for our DEA Certification scheme. You can add TrustMark for only £50+VAT.



RdSAP approved lodgement software

Stroma-certified DEAs receive a free download of our RdSAP software which is available to lodge EPCs on desktop and mobile. RdSAP is the standard assessment system which is approved by the Government to enable an energy survey to be completed before a domestic property is bought, sold or rented. All our DEA software is produced in-house (by our sister division – Stroma Software) and it is compliant with the requirements of RdSAP 9.92.
