Non-Domestic Energy Assessor Training 

Commercial Buildings in the UK require Energy Performance Certificates (EPCs) before being sold or let. As an Elmhurst trained Non-Domestic Energy Assessor (NDEA) you will be well equipped to undertake energy calculations on these commercial buildings, using approved Simplified Building Energy Model (SBEM).

Please Note: Given the ongoing situation with COVID-19, Elmhurst is currently unable to deliver this face to face training. An online version of the Non-Domestic APEL course is however, available to purchase via our training calendar. 


Established in 1993 and operating across the UK, Elmhurst Energy are recognised for driving standards of excellence in energy assessment. This starts with the high quality training and CPD that we provide.

A commercial/non-domestic building is typically more complex then your average run of the mill residential property, however Elmhurst's professional Non-Domestic Training focuses on making the complex, simple, though clarity of communication and support from our expert trainers. 

Elmhurst's Non-Domestic Energy Assessor Training covers everything from processing data into SBEM software to understanding of Building Regulations/Standards and Building Services. We also provide a number of training options depending on the level of service you wish to provide and your previous industry experience.

Training Options

Elmhurst’s NDEA training options include the Level 3 and Level 4 qualification. The level 3 qualification allows assessors to complete EPCs on all existing commercial buildings with frequently occurring characteristics- this covers a large proportion of the non-domestic market.
