The Energy Savings Opportunity Scheme (ESOS) and Pump System Audits

The Energy Savings Opportunity Scheme (ESOS) Regulations 2014 came into force on 17 July 2014 and are a mandatory energy assessment and energy saving identification scheme for large undertakings (and their corporate groups). The scheme applies throughout the UK. ESOS Energy Audits have the potential to increase businesses profitability and competitiveness by identifying cost-effective savings which, if implemented, will improve energy efficiency.

The scheme is estimated to lead to £1.6bn net benefits to the UK, with the majority of these being directly felt by businesses as a result of energy savings.

ESOS is the UK Government’s approach to transposition of Article 8(4) of the EU Energy Efficiency Directive, which requires all large (non-SME) enterprises to undertake energy audits by 5 December 2015 and every 4 years thereafter. The scheme’s regulations are published on the government’s legislation website More information about the Energy Savings Opportunity Scheme can also be found on the ESOS webpage

Guidance has also been published to help potential participants in the scheme understand their obligations and on page 43 of the full ESOS guidance document you will see that the ISO/14414-Pump System Energy Assessment standard is referenced as an auditing methodology that can be accepted by “Lead Assessors” approved by the Environment Agency. Accordingly it is hoped BPMA CPSA accredited persons (who are trained according to the IS0 14414 standard) will be recommended by Lead Assessors to undertake the pumping system elements of company energy audits.

And bear in mind:-

  • Pumps are the largest consumers of global motive power
  • Pumping System improvements can deliver up to 40% reduction in energy costs – and therefore improve user bottom line P&L account performance
  • The fact that BPMA’s CPSA scheme has been designed to help by equipping people with the skills to conduct a Pumping System Audit in accordance with ISO/14414

So when considering auditing your pumping systems, remember the BPMA Certified Pump System Auditor Scheme ( has established BPMA as THE body to train and certify personnel who undertake “Pumping System Assessments” as referenced in UK Government Energy Strategy documents.


BPMA are now offering the opportunity to attend a four day residential courses culminating in certification and eventual personal ID “Certified Pump System Auditor” status following approved audits.   See website for further details.
