Around 60% of large UK firms completed an audit under the mandatory Energy Savings Opportunities Scheme (ESOS) ahead of the 29 January deadline, according to the Environment Agency (EA).
The regulator previously revealed that around 4,000 firms had completed assessments by December, with 2,500 notifying their intent to comply by the 29 January cut-off point.
Major waste firm and ESOS auditor Veolia had said there were just under 10,000 eligible firms, a figure verified by the EA.
ESOS is a mandatory energy audit of the energy used by a company’s buildings, industrial processes and transport to identify cost-effective energy saving measures.
Now the deadline has passed, the EA has had 5,948 notifications of compliance and exactly 1,000 notifications of intent to comply.
This amounts to approximately 70% overall of organisations the agency believes qualify for ESOS.
Those who did not comply in time risk a fine.
An EA spokesperson said: “It will take some time to match all the notifications to the expected participant groups and verify whether the remaining organisations do in fact qualify.
“Our focus is on bringing organisations into compliance with ESOS and we will start contacting those organisations that have not yet complied this month.
“We will normally use enforcement notices to bring organisations into compliance and only issue civil penalties in the most serious cases.”
There was a late surge in compliance, with 1,015 notifications submitted in the last two days before the deadline.
