DECC has published the Government Response to the Energy Savings Opportunity Scheme (ESOS) consultation and laid regulations in Parliament to give legal effect to the scheme, and published guidance for potential scheme participants.

A copy of the Government Response and DECC Guidance can be found at:

ESOS is an energy assessment scheme that is mandatory for organisations in the UK that meet the qualification criteria. The Environment Agency is the UK scheme administrator.  Organisations that qualify for ESOS must carry out ESOS assessments every 4 years. These assessments are audits of the energy used by their buildings, industrial processes and transport to identify cost-effective energy saving measures.

Organisations must then notify the Environment Agency by a set deadline that they have complied with their ESOS obligations.  By 5 December 2015, qualifying organisations must carry out their ESOS assessment and notify the Environment Agency.  Participants must then carry out an ESOS assessment in each 4-year compliance period, ending on 5 December 2019, 2023 and so on.  By the end of 2014, the Environment Agency will provide information about the online notification system and when this will be available.  ESOS applies to large UK undertakings and their corporate groups. It mainly affects businesses but can also apply to not-for-profit bodies and any other non public sector undertakings that are large enough to meet the qualification criteria.

The Energy Savings Opportunity Scheme Regulations 2014 are published on

The Environment Agency, who have been appointed the scheme administrator for ESOS have also opened a help-desk to provide advice to potential participants on how to comply with the scheme. If you have any queries after reading the guidance, you can email the help-desk on:

The Environment Agency will also be publishing a summary of the scheme online

[EXTRACT] Case study 4: Camfil – ISO 50001 Energy Management System Implementation

Camfil develop air filters and clean air solutions, and operate globally. Already certified to the ISO 14001 environmental management standard, EN 16001 and the BSI Kitemark in Energy Reduction Verification, in 2011 Camfil decided to certify to ISO 50001.  Camfil has put energy management at the heart of its business model. It has initiated an energy reduction programme, the Camfil Energy Awareness Saves Environment (CEASE), and its key objective is to educate property and building managers about the financial and energy saving opportunities that can be made by replacing existing air filters with low energy air filters.

The introduction of ISO 50001, alongside its existing energy management processes, led to Camfil looking at its energy use in more detail and a focus on continual improvement of energy performance. This meant that previously unmonitored areas of energy use were identified and energy savings achieved that would otherwise have been overlooked.


As a result of the energy management steps that Camfil has taken, significant reductions in energy usage and improvements in energy efficiency have been achieved. These improvements resulted in Camfil saving over £200,000 on energy bills through minimal cost, self-funding opportunities.
