You'll need the Level 3 Certificate in Non-Domestic Energy Assessment.
You'll study towards this qualification if you have no experience of working in a relevant setting and are new to energy assessing. If you have experience in a related field like property surveying or construction you might not have to do as much training.
You'll usually need:
- 5 GCSEs at grades 9 to 4 (A* to C) including English, maths and science
