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 reduce the UK’s carbon emissions. The scheme requires affected businesses to carry out energy surveys accompanied by cost-effective recommendations to reduce energy demand and improve their energy efficiency. It is a mandatory requirement for organisations that must comply to produce an audit over a 12-month period once every four years.
