Energy Savings Opportunity Scheme (ESOS)




ESOS and the RIBA Plan of Work

What is ESOS?

The Energy Savings Opportunity Scheme (ESOS) applies to all UK organisations who meet the ESOS qualification criteria. Qualifying organisations are required to undertake ESOS audits in order to review their energy consumption and improve efficiency. Non-compliance could result in a fixed fine of up to £50,000, with a potential further £500 a day until rectified

Every four years, organisations must carry out energy audits for notification to the Environment Agency. Stroma Built Environment can act as your ESOS Lead Assessor to complete your ESOS compliance activity.

ESOS Energy Audits will consider:

Although ESOS is a mandatory requirement, the scheme can also be used to improve profitability and competitiveness by implementing lucrative energy efficiency improvements.
