ESOS – Are you on track?

The mandatory Energy Savings Opportunity Scheme (ESOS) requires ‘large enterprises’ to have energy audits done every four years by an approved Lead ESOS Assessor & signed off by a board-level director.

It may seem a bit of a pain to do this, but the commercial benefits are clear – save energy, save money, reduce risk and plan for the future.

The deadline is just 12 months away – 5th December 2019 – so you should be starting your ESOS projects now, to beat the rush before the Lead Assessors get booked up again.


I work with loads of organisations to do their ESOS Assessment – what’s Involved?

Measure Energy Consumption – Review energy uses & data for all relevant companies in the group – covering energy in buildings, processes, fuels & transport – to determine Total and Significant Energy Consumption.

Audits – Conduct audits to identify energy savings opportunities. My approach is different from standard assessors as I particularly focus on no cost & low cost opportunities, considering behavioural & operational changes, as well as relevant technologies.

Compliance Reporting – Report to be signed off by a director, before making formal notification of compliance to regulators.


I found in the first phase of ESOS that people didn’t want recommendations that a) are too expensive, b) take too long for payback or c) are difficult to implement. My ESOS Assessments take a wider look at energy management in your business, giving you useful & relevant energy efficiency recommendations.


What you should do now

1) Check if ESOS applies to you – ‘large enterprises’ have >250 staff or turnover >€50m & balance sheet >€43m. Smaller companies part of a larger group may also have to comply.

2) Collect energy data for your reporting period (one year covering 31st Dec 2018). Gas & electricity readings are usually reasonably straight forward, but many had trouble collecting the business travel data.

3) Identify who will take the lead on ESOS project, to liaise with your Lead Assessor & your board level director.

4) Start the audits, so that all the required sites have been covered.


Remember the deadline is 5th December 2019. Let me help you through your ESOS project so that you meet your legal obligations & get the commercial benefits too.
