Understanding ESOS Requirements for London Businesses

The Energy Savings Opportunity Scheme (ESOS) is mandatory for UK organizations that meet qualifying criteria: 250+ employees OR annual turnover exceeding £44 million OR balance sheet total above £38 million. Many London-based companies, particularly in financial services, professional services, and corporate headquarters operations, exceed these thresholds.

ESOS requires comprehensive assessment every four years, with the next compliance deadline (Phase 4) in June 2027. The assessment must cover at least 90% of your organization's total energy consumption and include:

  • 12 months of energy consumption data.
  • Site visits to representative London facilities.
  • Analysis by an ESOS Lead Assessor.
  • Identification of all energy saving opportunities.
  • Board-level sign-off and Environmental Agency notification.
  • Organizations with ISO 50001 certification covering 90%+ of energy use can achieve ESOS compliance through this alternative route.
