Energy Saving Opportunity Scheme Compliance Services
ESOS compliance through ISO 50001 or ISO 50002
Ensure ESOS compliance by implementation of ISO 50001 or conducting an energy audit.
Energy Saving Opportunity Scheme (ESOS) is a crucial UK legislation that applies to large organisations with more than 250 employees or a turnover exceeding £44.1m. Non-compliance can result in significant fines, with penalties reaching up to £100,000 (for more details, visit GOV.UK). To meet ESOS requirements, qualifying organisations, including buildings, facilities, transport, and industrial processes, must follow one of two routes:
A. ISO 50001 Implementation
Implement an Energy Management System in alignment with ISO 50001, certified by a UKAS-accredited Certification Body. With a certified ISO 50001 system in place, there is no need for an additional assessment or a qualified lead assessor to review your activities.
- Contribute to the organisation’s continual improvement.
- Improve overall performance, reducing energy consumption and costs.
- Identify and manage risks associated with energy performance.
- Measure and monitor energy-related data to make informed decisions and prioritise energy conservation opportunities.
