Sebastian Gray Leads Seminar on ESOS

Sebastian Delivers Seminar at Facilities Show

As one of the first CIBSE Registered ESOS Lead Assessors and a Director of 2EA®, Sebastian Gray was recently invited, with CIBSE, to lead a seminar at the Facilities Show at the Excel Centre in London.

During his presentation Sebastian was given the opportunity to share his knowledge and experience in the latest government energy initiative; the Energy Saving Opportunity Scheme (ESOS).

Sebastian covered the requirements of the participants undertaking ESOS assessments, explaining the steps that are needed to meet requirements, from planning to completion including topics such as; who must comply, what is expected of them and what fines and penalties apply to those that fail to comply or miss compliance deadlines. He then went on to break the process down into three simple steps.

Who must comply and what is expected?

You must comply with ESOS if you meet any of the following criteria:

  • You have 250 or more staff.
  • You have
  • You are part of a corporate group which includes a large undertaking as defined in either of the above.

As a participant of the Energy Savings Opportunity Scheme you are expected to:

  • Measure all your energy use for a continuous 12 month period.
  • Undertake audits covering all your main areas of energy consumption*.
  • Report your compliance to the environment agency by the compliance date.

*De-minimis of 10% allowed

Three simple steps

Sebastian broke the auditing and compliance process into three simple steps:


The first step is to gather relevant data and engage management and directors before assigning a Lead Assessor to complete a scope and audit plan.

ESOS Audit

The second step is to undertake auditing of the specified areas classified in the scope and audit plan and identify any energy saving recommendations.

A report can then be compiled, which includes an identification of savings opportunities. This must be signed off by a specified Director and an ESOS Lead Assessor. The participant can then register their compliance with the Environment Agency.

Evidence Pack & Compliance

An evidence pack is produced that includes the following data:

  • ESOS qualification
  • Scope of participation
  • Corporate groupings and responsibilities for compliance
  • Calculation of total energy consumption/use of de-minimis
  • Selection of site auditors/lead assessors
  • Audit methodology/audit plan/audit reports
  • Evidence of sign off
  • Compliance checklist/voluntary disclosure questions
  • Record of compliance/record of communications

Key Takeaways

At the end of his talk Sebastian provided his audience with some key takeaways to help them on their route to compliance and avoid costly fines and penalties:

  • You must act soon to meet deadlines and avoid penalties
  • Board level engagement is a necessity
  • Staff engagement and training can provide easy wins
  • Consider this as an opportunity to save money in your business and not just as a “sign off” exercise
  • Look at it as a reputational driver
  • Choose your Lead Assessor carefully to match your business
  • Finally, plan for the future – this is only the first phase of ESOS
