Energy Savings Opportunity Scheme (ESOS)

What is ESOS?

The Government introduced the Energy Savings Opportunity Scheme (ESOS) to incentivise large businesses to implement energy-saving measures and help to cut UK carbon emissions. Businesses must carry out an audit of their energy-consuming activities and identify cost-effective energy-saving measures once every four years.

Who needs to comply?

Companies need to comply with ESOS if, on the 31st December 2018, they have:

How can ENGIE help?

ENGIE has extensive experience of helping businesses to comply with ESOS. Our dedicated team is fully qualified to guide your company through the compliance process from start to finish. We will save you time and resources in managing the data collection, analysis and report production required for ESOS compliance. You will have the peace of mind that, with our support, your business will comply fully with all ESOS obligations.

To comply with ESOS, your business needs to measure its total energy and fuel consumption across all buildings, transport and industrial activity for a 12 month period inclusive of the ESOS qualification date, which is 31 December 2018. You must then conduct energy audits covering at least 90% of your total energy consumption to identify cost-effective energy-efficiency measures.

Another, more comprehensive, route to compliance is ISO 50001; by operating to the internationally recognised energy management standard, your organisation fulfills the requirements of ESOS and is exempt from conducting further audits. You only have to complete the online EA ESOS submission.
ENGIE has trained ISO 50001 implementers and internal auditors so can facilitate your ISO 50001 goals.

Our specialists will help you collect, quantify and analyse your data, and carry out the energy audits. Based on the audit, we will identify suitable energy-saving measures and give you an indication of the potential cost and energy savings you can achieve.

Your ESOS assessment must be reviewed by a board-level director and approved by an ESOS Lead Assessor.
Our assessment will be signed off by one of our Lead Assessors.

Your compliance must also be reported to the Environment Agency. In Scotland the compliance is submitted to the Environmental Agency but enforced by the Scottish Environment Protection Agency (SEPA).

We will produce a report on your company’s current energy consumption and potential for savings, and report your compliance to the Environment Agency.

There is no mandatory requirement for businesses to implement the energy-saving opportunities identified by the ESOS audits. However, they do offer a valuable opportunity for you to reduce your energy use and costs. The measures identified could range from simple ‘quick-fix, fast-return’ solutions, such as installing LED lighting, through to longer-term investment programmes. 
Implementing such measures will ensure you see a positive, and potentially significant, return on your investment in ESOS compliance.
