Energy Saving Opportunity Scheme (ESOS)

What is ESOS?

The Energy Savings Opportunity Scheme (ESOS) was introduced to incentivise large UK based businesses to implement energy-saving measures and help to cut UK carbon emissions. The scheme requires affected businesses to carry out energy surveys accompanied by cost-effective recommendations to reduce energy demand and improve energy efficiency. It’s a mandatory requirement for organisations that must comply to produce an audit over a 12-month period once every four years.
