Energy Assessors in England & Wales and N. Ireland can only lodge EPCs within their accreditation banding, which can be at one or several levels depending on their experience on the different calculation tools:
Level 3 can undertake energy inspections of existing simple non-dwellings with frequently occurring characteristics using the SBEM method.
Level 4 can undertake energy inspections of new-build and existing simple non-dwellings using the SBEM method.
Level 5 can undertake energy inspections of any new-build and existing non-dwellings using the DSM method.
If you are qualified at Level 4 you are automatically qualified at Level 3. However, being competent at Level 5 does not make you competent at Levels 3 and 4.
