    Turning ESOS compliance into a significant opportunity for energy cost savings.
    ESOS is a mandatory energy assessment scheme for organisations in the UK that meet the qualification criteria. The scheme requires the recording and reporting of energy data for buildings, transportation, and industrial processes. Furthermore, energy surveys are required, which must be accompanied by cost-effective recommendations to reduce energy demand and improve energy efficiency. All evidence must be signed off by an accredited ESOS Lead Assessor.

    You must participate in ESOS if your company qualifies as a large undertaking in the UK, which means you must meet one or both of the following conditions:

    • Employs 250 or more people
    • An annual turnover in excess of £44 million, and an annual balance sheet total in excess of £38 million.

    We would like to inform you that The Department of Energy Security and Net Zero, formerly known as BEIS, will be extending the deadline for ESOS Phase 3. The new deadline for compliance is deferred to June 5, 2024, which replaces the previous deadline of December 5, 2023. This extension is in response to recent changes requiring businesses to provide additional data to ensure compliance with ESOS regulations. We hope that this update is helpful and enables businesses to comply with the regulations effectively. Organisations that fail to comply with the requirements set out by ESOS could be liable to compliance and enforcement activities and substantial financial penalties, an initial penalty of up to £5,000, plus £500 for each working day the organisation is in violation.

    Our in-house ESOS Lead Assessors have assisted numerous businesses across several sectors to comply with their obligations for Phase 2. We will work alongside you through the entire process, advising you on the best route to compliance, helping you gather corporate, data and site information, conduct site surveys, identify your significant energy consumption, compile evidence and the directors the report required for compliance, and summarising all opportunities with future action suggestions.
