Does your organisation need to comply?

ESOS generally applies to larger organisations. You will need to comply with ESOS if you have:

  • >250 employees

  • Turnover in excess of €50,000,000 and a balance sheet greater than €43,000,000


If your organisation need to comply, then Enica can help. Here’s our approach to compliance:

STEP 1: Understand your organisation’s company structure. We can usually help by exploring public Companies House records for this. ESOS usually applies at UK highest parent company level, so we need to understand and subsidiary companies in the group.

STEP 2: Understand how many UK sites your organisation has and whether transport activities need to be included.

STEP 3: Collect your energy consumption and transport data. This may include electricity, gas and other energy sources that your organisation uses. The objective is to understand 100% of your energy consumption.

STEP 4: Determine what assets/sites would need to be audited to cover at least 90% of your energy consumption. This could also include assessment of a sampling approach if it can be confirmed that assets/sites are similar in activity.

STEP 5: Undertake energy audits in accordance with BS EN 16247 (Energy Audits).

STEP 6: Compile your ESOS evidence pack. This must be signed off by a qualified ESOS Lead Assessor and a senior director of your organisation.

STEP 7: Notify the Environment Agency of your compliance.

Enica can deliver all of the steps needed for compliance.
