If you’re working full-time for a company then it is expected that you would work between 35 and 40 hours per week. However, if you’re self-employed then you have the option of working full-time, part-time, seasonal or by contract. In other words, if you work by yourself then you have to come up with the best suitable hours, working arrangements and contracts possible.


The position of commercial energy assessor will require these professionals to have the following skills:

-          Strong communication skills – both verbally and written – to explain to clients

-          Superb observational techniques that can identify all forms of energy waste

-          Impeccable computer acumen in order to produce invoices, insert data, etc.

-          Sublime accounting abilities that can allow you to balance the books and do your taxes

-          Excellent understanding of construction materials, techniques and companies


At the very minimum, every commercial energy assessor needs a Bachelor’s degree in any of the STEM fields as well as additional educational credentials in anything related to the environment, ecology and green technologies. Extra training in accounting, business or marketing would be a prudent step to take.

Once educational qualifications are met, commercial energy assessors need to attain a Level 3 Certificate in Non-Domestic Energy Assessment and be registered with a Department for Communities and Local Government (DCLG) approved accreditation program.

Career Prospects

With governments and regulatory bodies mandating that buildings need to be more environmentally sound, it is projected that there will be a growing need for commercial energy assessors. The outlook for this occupation, and its overall field, is slated to increase globally by 28 percent between the years 2012 and 2022.

Energy efficiency has been the big thing in the developed world today. From governments trying to be green to the private sector attempting to adhere to government standards and entice consumers to use them because of their green initiatives, commercial energy assessors will be in strong demand over the next couple of decades.
