ESOS Compliance Made Simple: Expert Support for UK Businesses

Navigate ESOS Phase 4 with confidence. We combine real energy data with specialist expertise to make your compliance audit accurate, efficient, and audit-ready.

What is ESOS?

The Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment scheme for large UK organisations. If your business has 250 or more employees, or meets the financial thresholds (more than £44m annual turnover and more than £38m balance sheet total), you are legally required to carry out an ESOS audit every four years. The next compliance deadline is Phase 4: December 2027.
