ESOS Energy Savings Opportunity Scheme


What Is It?

The ESOS Energy Savings Opportunity Scheme is a brand new mandatory energy assessment and energy saving identification scheme for businesses in the UK.

The ESOS Energy Savings Opportunity Scheme aims to save the UK at least £1.6bn in energy costs by the year 2030.



When is it happening?

The ESOS Energy Savings Opportunity Scheme will mandate energy audits for around 9,000 UK businesses.

You are likely to be in the ESOS Energy Savings Opportunity Scheme if, on the qualification date of 31st December 2018 for the second phase of ESOS) you are:

-An Undertaking which has 250 or more employees in the UK.
-An Undertaking which has fewer than 250 employees, but has:
-An Annual turnover exceeding €50m and,
A balance sheet exceeding €43m

Part of a corporate group which includes an undertaking which meets criteria 1 or 2 above.


ESOS Opportunities Include

-Lead assessors will manage teams which could include Non Domestic Energy Assessors.

-An ESOS Report will measure the energy consumption for buildings, transport or processes.

-Only a registered lead assessor can sign off on an ESOS audit.

-Over 10,000 UK companies will require an ESOS report before December 2018

-A great opportunity for DEC Assessors to take advantage of this new industry.


How do I benefit from ESOS as an energy assessor?

Large companies have to comply with ESOS until 5th December 2015. As every ESOS report has to be signed off by a Lead Assessor, there will be a big demand for experienced commercial assessors who meet the competencies set out in the PAS 51215:2014 document.

Please note that you have to meet the above mentioned competencies and become part of an Approved Register to be able to work as a Lead Assessor. However that does not mean that DEC and Commercial assessors cannot be involved in the ESOS scheme. Lead Assessors can work with as many assessors as necessary to be able to gather the required data for an ESOS report.

Whether you are an energy assessor looking to work for a Lead Assessor or a company looking for a Lead Assessor for an ESOS report, you can get in touch with our Approved Lead Assessors whose details will be listed on our website shortly under ‘Approved Lead Assessors’.
