ESOS Compliance
We’re here to help you on your journey to compliance with the Energy Savings Opportunity Scheme (ESOS).
What is ESOS?
The Energy Savings Opportunity Scheme (ESOS) is a mandatory compliance scheme in the UK, derived from Article 8 of the EU Energy Efficiency Directive. ESOS aims to reduce EU energy consumption by 20% by 2020. ESOS occurs in four-yearly phases and introduces regular energy audits that highlight energy savings for large businesses.
These audits must cover 90% of your organisational energy and require sign-off from a qualified ESOS Lead Assessor. Routes to compliance include ESOS audits, Display Energy Certificates (DECs), Green Deal energy assessments and ISO 50001 certification.
Who needs to comply with ESOS?
Public bodies are not affected. Large organisations that must comply are classified as those with:
- More than 250 employees or
- A turnover of more than €50,000,000 and an annual balance sheet total of more than €43,000,000
Why comply with ESOS?
Avoid penalties
Regulating bodies – such as the Environment Agency (EA) in England and Wales – have the authority to apply civil penalties against those mandated companies not participating in ESOS or found to be non-compliant with its requirements. Fines are administered on a case-by-case basis but can be:
- An immediate fine of between £5,000 to £50,000
- Plus up to £500 per day for up to 80 working days
- Plus you could be ‘named and shamed
You’re at a greater risk of fines if you ignore an Enforcement Notice. The Phase 1 ESOS compliance deadline was back in 2015 – the EA were still issuing Enforcement Notices to bring companies into compliance long after that deadline.
Seize opportunities
ESOS is a real chance to improve the efficiency of your business and make significant cost savings. With the right partner, initial compliance activities can be effectively the very first investment on the path to energy savings and cost reduction. We can help you implement solutions identified in your ESOS recommendations report.
