December 2015 every large enterprise in the UK
will, by law, have to undertake an energy audit, an ESOS
audit. This ESOS audit will then have to be repeated
every four years. The law itself is the UK bringing
into force Article 8 of the EU Energy Efficiency Directive,
itself part of the EPBD.
The intention is that every
audit will recommend cost-effective measures that will save
Organisations energy and money. Saving money on escalating
energy bills will make business operations more efficient.
The ESOS scheme and Greenhouse Gas Regulations will also
contribute to meeting greenhouse gas reduction targets.
Only businesses with more than 250 employees or
an annual turnover of more than €50 million will be captured
by the ESOS scheme. There may also be exemptions
put in place for businesses that can demonstrate that they
already have a robust approach to reducing energy use, for
example if they have achieved the Carbon Trust Standard, but
that will only be confirmed as ESOS is launched fully in

8 of the EU Energy Efficiency Directive (‘the Directive’)
requires all Member States to introduce a programme of
regular energy audits for ‘large enterprises’. This is the
Audits must be undertaken by 5 December
2015, and then at least every four years from the date of
the previous audit.
The ‘Energy Savings Opportunity
Scheme’ (ESOS) is the Government’s proposed approach to
implementing this requirement. Under the scheme, approved
Assessors such as those trained by ACI Reports will
carry out Article 8 compliant ESOS assessments to identify
energy saving recommendations.
Importantly, the ESOS
Audit will need to be undertaken by a qualified ESOS
Assessor, and as at April 2014 the National Occupation
Standard (NOS) for training has not been set, neither has
the Governing Body; ACI Reports urge Clients to hold back
and not rush into ESOS without professional advice, a
standard Energy Audit is unlikely to pass the ESOS test.
What is an ESOS assessment?
Energy Efficiency Directive sets out ‘minimum criteria’ for
‘energy audits’. To meet these criteria, the Government
considers that ESOS assessments must provide the following
information at a minimum:
A review of the total
energy use and energy efficiency of the organisation. This
would include the organisation identifying and measuring an
energy intensity ratio (e.g. energy use per employee) and,
as appropriate, considering the variation in energy
use over time within key buildings, key industrial
operations, and key transport activities. The review would
need to be proportionate and sufficiently representative ‘to
permit the drawing of a reliable picture of overall energy
performance’ of the organisation;
on potential savings, which identify and quantify
cost-effective energy savings opportunities. These should
be, wherever practical, based on life cycle assessment (LCA)
instead of simple payback periods (SPP).
ESOS assessments are intended to recommend cost-effective
measures to save organisations energy and money. These might
include, for example, advice on updating lighting systems,
taking steps to encourage staff to adopt more energy
efficient behaviour, or (if cost-effective) replacing
elements of a transport fleet.
within the scheme would need to identify an approved ESOS
assessor (either an in-house expert or an external
consultant) to conduct the ESOS assessment, gather data on
energy usage at an appropriate level of detail, and
undertake an ESOS assessment by December 2015, renewing the
assessment at least every four years thereafter.
The current Government consultation includes a number of
options on compliance reporting of ESOS assessments. A
scheme administrator will be established to ensure
compliance with the scheme to conduct ESOS assessments, but
one has not been appointed yet. Depending on the compliance
route chosen, Organisations may need to notify the scheme
administrator that they have conducted an energy audit, and
potentially disclose any key action taken in their annual
The Government is developing a route to
accredit/qualify individuals as fit to carry out ESOS
assessments. This is where ACI Reports Ltd ESOS Qualified
Assessors will come in, who are completely independent and
not tied to an organisation selling products.
Reports are currently awaiting the outcome of the ESOS
consultation which will be published in Spring 2014;
training ESOS Assessors will commence as soon as possible.
Beware of Organisations claiming to offer ESOS
It has become apparent that
some companies in the market place are advertising that they
have the accreditations required to comply with ESOS and are
able to provide energy efficiency audits that meet ESOS
requirements, however this is seriously misleading
information and fundamentally inaccurate.
initiative has only recently been triggered. The Government
intends to bring forward secondary legislation in spring
2014 setting out the legal framework for the operation of
the scheme, so that the UK can meet the 5 June 2014 EU
deadline for transposition of the Energy Efficiency
Therefore, at this moment in time, there
can be no guarantee of an energy efficiency audit fulfilling
ESOS requirements or meeting ESOS guidelines. There is also
no confirmation of exactly what organisations fall within
the requirement or any exemptions.
Although a company
may be able to provide an energy audit, details of ESOS are
not complete and it would therefore be wrong to claim any
sort of accreditation to the scheme.
It would be sensible for
organisations that anticipate being effected by ESOS to
speak with us now in preparation, as time will be short when
ESOS commences in mid 2014.
