DEA Certification

Non-Domestic Energy Assessment Certification (NDEA)




Non-Domestic Energy Assessment Certification (NDEA) is provided by Stroma Certification for the energy assessment of non-domestic buildings. Our certification scheme is authorised by the Ministry of Housing, Communities and Local Government (MHCLG) and allows NDEA members to lodge Energy Performance Certificates (EPCs) for commercial buildings.

Annual Certification £0. LODGEMEMT FEE – £19.64 – £24.64*. LANDMARK FEE - £12.82
All quoted prices exclude VAT. Your total lodgement fee will be the fee per lodgement, plus the Landmark fee. Our lodgement fees are priced on a sliding scale based on the number of lodgements made per annum.


What is the NDEA Certification Scheme?

EPCs are mandatory upon construction, sale or rental of any non-domestic building, whether new or existing. An assessment must be carried out by an accredited assessor and an EPC generated, which gives the building a rating of A–G (A being the most energy efficient).

An EPC is also accompanied by an Advisory Report (AR), which outlines ways in which energy can be saved and provides recommendations that include the short, medium and long-term paybacks of various green technologies. The implementation of these recommendations would reduce the building's CO2 emissions, as well as fuel costs.

By joining our NDEA Certification scheme you will be able to provide these non-domestic energy assessment services to commercial customers.

Why join our NDEA Certification Scheme?

Stroma Certification ensures a great package for our assessor members with highly competitive lodgement fees. We don’t charge you for joining and you won’t be charged membership fees in the first year or thereafter.

We offer regular CPD and training events to help you fulfil your annual CPD obligations (10 hours per year). Non-domestic technical support is also available to members via phone and email.


DEA Certification


Minimum Energy Efficiency Standards (MEES)

In 2017, the Government implemented Minimum Energy Efficiency Standards for domestic and non-domestic properties. Under the MEES regulations a commercial property may not be let unless it meets a minimum EPC rating of ‘E’. Stroma-certified NDEAs can advise landlords and other commercial property stakeholders about which properties are at risk of non-compliance under MEES. By undertaking our MEES training course you can help your customers to avoid costly fines which can be levied for MEES non-compliance and advise on the measures which can be taken to make a non-domestic property more energy efficient.
