Legislation behind ESOS
The government originally established ESOS to implement Article 8 (4-6) of the EU Energy Efficiency Directive 2012/27/EU.
ESOS came into force in July 2014 under the Energy Savings Opportunity Scheme Regulations 2014 – referred to in this guidance as ‘the 2014 ESOS Regulations’.
The regulations were amended in 2018 and 2020 to address inconsistencies arising from the UK’s exit from the EU, including setting the financial thresholds in £ Stirling instead of Euros and to amend references to the ISO 50001 energy management standard to include the 2018 revision of the standard.
Following the UK’s exit from the EU, replacement primary powers were established in the Energy Act 2023.
ESOS regulations were amended to include new requirements in 2023 through The Energy Savings Opportunity Scheme (Amendment) Regulations 2023 – referred to as ‘the 2023 amended ESOS Regulations’.
