Qualification is based on the status of your organisation on the relevant qualification date.
If your organisation qualifies, you must participate in ESOS and notify compliance to the Environment Agency by the last date of each compliance period (‘the compliance date’).
The deadline for the first compliance period was 5 December 2015 with the second compliance period ending 5 December 2019. If these deadlines were missed action still needs to be taken.
The next compliance date will be 5 December 2023, with the qualification date of the 31 December 2022.
