What are you doing about ESOS Phase 2?

The Energy Savings Opportunities Scheme (ESOS) was introduced by the Government in 2014. This will require large companies to periodically (every four years) complete energy audits which cover 90% of energy usage within the company to help reduce UK carbon emission. The energy assessments and overall compliance must be signed off by a qualified Lead Assessor who is registered by an approved professional body.

How Boxfish can help

We have highly qualified and experienced ESOS Lead Assessors / Auditors who are ready to help. Not only will you comply with the ESOS Phase 2 deadline but you could save money on your energy costs.

Qualifying organisations that do not submit confirmation of their compliance to The Environment Agency by the deadline of 5th December 2019 are in breach of the regulation and at risk of enforcement action and penalties. It should be noted that The Environment Agency has recently investigated 2,400 organisations and commenced civil penalty proceedings against some non-compliant organisations.

Qualifying companies

Companies need to comply with ESOS if at least one UK group member falls into one of the below categories:

  • Have more than 250 employees (including overseas companies with a UK registered establishment which are paying tax in the UK)


  • Have an annual turnover of more than €50m (£39m) & an annual balance sheet total of more than €43m (£33m).

To comply, companies must:

  • measure their total energy consumption;
  • conduct audits to identify cost-effective energy efficiency opportunities; and
  • report compliance to their national scheme administrator – the Environment Agency in England, SEPA in Scotland, NIEA in Northern Ireland and NRW in Wales.

Other routes to compliance are available, such as ISO 50001.

Get ahead of the deadline

The deadline for ESOS Phase 2 is 5th December 2019.

Qualifying organisations that do not complete and notify by this date are in breach of the regulation and at risk of enforcement action and penalties.

Our experienced team can guide you through the compliance process, from the early stages to the final submission. Our support includes managing data collection, analysis and report production required for ESOS compliance.

The ESOS energy assessment will be reviewed and signed off by our highly qualified ESOS Lead Assessors. We will also compile the evidence pack that is required following final submission.

For the December 2015 deadline (Phase One) we audited more than 80 sites for ESOS assessment and identified opportunities to reduce energy by over 9,500 MWh per annum, which is equivalent to energy cost savings of over £700,000 and over 4,000 tonnes in carbon dioxide emission per annum.
