ESOS phase 2: Why start now?


In this sponsored post, Inspired Energy outlines why organisations should not delay in starting compliance work for the second phase of the government’s ESOS energy efficiency scheme.

What is ESOS?

The Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment and energy saving identification scheme. ESOS is in four-yearly phases and requires the organisation to measure its total energy consumption, including within buildings and transport usage, conduct energy audits to identify cost-effective energy saving recommendations, and report compliance to the Environment Agency.

Non-compliances, such as failure to submit the compliance assessments on time, can incur a variety of penalties from the EA for the non-compliant company. These can range from publication of non-compliance on the EA’s website, to a £50,000 fixed penalty plus £500 per day.

Phase 2

ESOS Phase 2 offers a number of benefits including a fresh look at site energy demands and the continuation of an energy reduction strategy.

The reference period for the Phase 2 window began January 2018, so it’s time to act now.

Compliance with the second phase of the scheme must be completed and reported to the EA by 5 December 2019.

Inspired Energy are now actively managing ESOS Phase 2 auditing, reporting and implementation. 

Does my organisation qualify for ESOS?

ESOS applies to UK organisations and their corporate groups that are large enough to meet the qualification criteria. The qualification thresholds are:

  • any UK company that either:
  • employs 250 or more people, or
  • has an annual turnover in excess of 50 million euro (£38,937,777), and an annual balance sheet total in excess of 43 million euro (£33,486,489)
  • an overseas company with a UK registered establishment which has 250 or more UK employees (paying income tax in the UK)

How can Inspired Energy help?

Inspired Energy provide a compliance service that encompasses all required aspects of the ESOS Assessment. These include:

  • Provision of a qualified ESOS Lead Assessor to complete, oversee or review any Energy Audits, to ensure they meet the requirements of ESOS, and to sign off on the overall ESOS compliance submission.
  • Collation of annual energy consumption, ensuring that this overlaps with the qualification date as required by ESOS.
  • The identification of the ‘areas of significant energy consumption’, ensuring that these cover the minimum of 90% of total energy consumption.
  • Advice on the best compliance method for each area of significant consumption.
  • Site visits as required to conduct ESOS Compliant Energy Audits.
  • Provision of full Site Energy Reports detailing all energy efficiency improvements available, and where they would be applicable to a larger portfolio, if required.
  • Full energy consumption profiling, made available in a variety of formats and reports from Inspired’s advanced energy reporting system.
  • Creation and maintenance of a comprehensive Evidence Pack to store all relevant documents and information relevant to the organisation’s compliance activities.
