The ISO Show: Episode 12 – How to comply with ESOS
Last week we covered what ESOS is, who qualifies and a brief
explanation of methods of compliance. In this week’s episode we’ll go into more
detail on the methods for compliance, namely ESOS Energy Audits and ISO 50001.
Which sites are in scope of ESOS?
What energy consuming activities are undertaken at each site?
Calculate the % of total energy consumption for each site and activity
Plan where to focus the ESOS audits in order for the organisation to gain the most benefit
Note: Flexibility to
exclude up to 10% of your identified energy consumption under the de minimis
rule. Any exclusions must be clearly detailed within your Evidence Pack
together with the rationale for exclusion.
Conducting the audit (competence, sampling)
The audit plan and methodology should be developed before
the audits begin and should be retained in your Evidence Pack.
When reviewing your ESOS scope, you might identify that you have a range of similar operations i.e. you may have small satellite offices or similar retail units, so you can simply take a sample of these.
A registered Lead Assessor must oversee your ESOS assessment, but individual audits can be carried out by suitably skilled people who are not Lead Assessors.
Note: Blackmores can provide qualified personnel to do these audits.
collection and analysis
Where to find your data?
Facilities managers – for meter readings and
Your travel team – for information on journeys
undertaken and distances travelled
A maintenance team – for meter readings and
Vehicle fleet managers – for information on
vehicles, fuel purchased and distance travelled
opportunities for improvement
The approach taken will need to be tailored to the business
but could include:
financial savings offered by the improvement
measures and the necessary investment required;
return on investment (or other agreed economic
The comparison in terms of both cost and energy
consumption between alternative energy efficiency improvement measures;
The scope and boundaries of the audit

compliance to the EA
Once the ESOS report has been reviewed and signed off by the
ESOS Lead Assessor and either one or two Directors, the business can then
register their compliance with the environment Agency.
Notification is made via an online notification system.
The most effective route to ESOS compliance if to implement an energy management system compliant to ISO 50001.
ISO 50001 is a best practice framework to help organisations
to improve their energy performance and energy efficiency, thus, reducing their
energy consumption and carbon footprint.
