Every four years, large companies are required to prove their compliance with the Energy Savings Opportunities Scheme (ESOS). This provides an excellent opportunity for energy assessors working in the non-domestic sector to train as ESOS Lead Assessors.
Practical day included!
Our ESOS course is one of the only courses that includes a practical day; providing you with both theoretical knowledge and the practical skills to confidently carry out an ESOS assessment.
The first three days will be spent in the classroom where you will learn all the technical skills and knowledge required to become and ESOS Lead Assessor. The final day will be spent ‘out in the field’ where you will conduct an audit for buildings and transport.
Our professional and friendly training is delivered at a pace to suit all individuals and ensures those who attend leave feeling confident about putting what they’ve learned into practice.
Please note: The ESOS application form will be emailed across to you once payment for this course has been processed. Please ensure the AP95 application form is completed and returned to as soon as possible, before the training starts. In the event this is not filled in and accepted before the course takes place, Elmhurst is not liable for any cost incurred.
Course Breakdown
This four day course covers all relevant information needed to qualify as an ESOS Lead Assessor. At the end of the Training course there is a paper based assessment paper consisting of 20 multiple choice questions and the pass mark is 75%. If the candidate fails the paper based assessment they will be offered one further attempt to pass. In the event that a candidate fails the exam twice, they will have to wait a minimum period of three months before any further attempts can be made. We reserve the right to charge for any further exam attempts. Once you have successfully completed the course you can join Elmhurst’s ESOS Lead Assessor Scheme and start conducting audits.
