ESOS (Energy Savings Opportunity Scheme)

Energy assessments create opportunities

The Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment and savings identification scheme for large undertakings in the UK.

Organisations that qualify for ESOS must;

  • Have over 250 employees or turnover of over £44.1m or an annual balance sheet of over £37.9m, or is part of a larger organisation, which falls into any of the above
  • Audit the energy used by their buildings, industrial processes and transport to identify cost-effective energy saving measures.
  • Carry out energy surveys by an accredited ESOS engineer
  • Notify the Environment Agency (EA) by a set deadline that they have complied with their ESOS obligations. Otherwise face fines of up to £90,000

Even though the ESOS Phase 2 deadline has passed, it’s not too late to act. Our ESOS experts can help you mitigate any fines by starting the compliance process as soon as possible.

Our engineers have been working with ESOS since it's inception, being involved on the initial 100 compliances in 2015. We have helped over 80 companies comply with ESOS and identified thousands of pounds in energy saving opportunities. We can help you prepare and prosper in the next phase.
