What Is ESOS?

Administered by the Environment Agency, the Energy Saving Opportunity Scheme (ESOS) is a mandatory EU energy assessment scheme for all large UK undertakings.
These audits of the energy used by large companies in their buildings, industrial processes and transport are used to identify cost-effective energy-saving measures. The latest deadline for notifying The Environment Agency that an organisation is ESOS-compliant is 5th December 2015 and then every 4 years thereafter.

ESOS - Do You Need to Comply

Who carries out ESOS assessments?

If you qualify for ESOS and your organisation is not fully covered through ISO 50001 certification, you need to appoint a lead assessor to conduct and/or supervise your energy audits and approve your overall ESOS assessment. Lead assessors can be employees or from external contractors as long as they are registered members of an approved professional body.
As a knowledgeable, experienced and approved assessor, ERIKS can help you carry out and/or review your assessments, compiling the necessary Evidence Pack for submission to The Environment Agency in time for December deadline and avoiding the potential financial penalties that can range between £5,000 and £50,000.
