ESOS

ESOS

Requires that large (undertakings) organisations in the UK undertake comprehensive

assessments of energy use and energy efficiency opportunities at least once every four years.

The criteria for inclusion to ESOS applies to any large undertaking that carries out a trade or

a business (most commonly a Company), and any corporate group where at least one member

of the UK group meets the ESOS criteria.

  • A large undertaking is one that employs at least 250 people,
  • Or has an annual turnover in excess of €50 million and a balance sheet in excess of €43 million.
  • Most public sector bodies are excluded, but other organisations that receive some public funding, such as universities, may qualify.

We are now in Phase 3 of the ESOS compliance scheme. The regulations require large UK

organisations to take three important steps before the compliance date of 5 December 2023:

  1. Measure total energy consumption for buildings, industrial processes and transport
  2. Conduct audits to identify cost-effective energy efficiency recommendations for areas of significant energy consumption; and
  3. Report compliance to their national scheme administrator – the Environment Agency in England, SEPA in Scotland, NIEA in Northern Ireland and NRW in Wales.

To comply with the regulations, a Lead Energy Assessor will need to conduct the ESOS Assessment. If an organisation has ISO 50001, they are already compliant through ISO 50001 and just need a lead assessor to submit the evidence via a lead assessor.
