Lead Energy Assessor's Energy Savings Opportunity Scheme

Guide to ESOS

The Energy Savings Opportunity Scheme (ESOS) is a policy aimed at increasing the energy efficiency of UK businesses and so mitigating the effects of climate change. 

The scheme requires that all large ‘undertakings’ in the UK to undergo a mandatory assessment of their energy use and opportunities to improve their energy efficiency across their sites by 5th December 2015 and then on-going every four years.

National Energy Services has now been approved by the Environment Agency to be an ESOS Lead Assessor Register. If you are interested in becoming a registered Lead Assessor, we are running ESOS lead assessor training.

 Please note application forms should be submitted at least 5 working days before course date start at the latest due to the time required for technical review and potential queries.

Benefits of an energy efficient audit

Implementing energy efficiency measures identified through these energy efficiency audits can:

  • Reduce energy costs – the Carbon Trust estimate annual energy costs can be reduced by 20% through energy efficiency and improved energy management.
  • Reduce other costs – for example from waste disposal and maintenance.
  • Show the business is playing its part in tackling climate change - saving energy is good for the UK as a whole.
  • Increase employee engagement – studies show that improving comfort in the workplace environment and working for a socially responsible company improves employee engagement and motivation
  • Improve the business profitability and competitiveness.

Whether or not an organisation is subject to ESOS regulations, it makes great business sense to get an energy audit.

Which organisations are subject to ESOS regulations?

The ESOS regulations apply to any large undertaking or enterprise that carries out a trade or a business, which includes any corporate group where one or more members of the UK group meets the ESOS definition of a large undertaking.

This means that the organisation is subject to ESOS regulations if they:

  • Have 250 or more employees, or
  • Have fewer than 250 employees, but have an annual turnover exceeding €50m and a balance sheet exceeding €43m, or
  • Are part of a group that includes at least one entity that that meets any of the criteria above.

It’s not just businesses that are subject to ESOS regulations. The definition means that organisations that traditionally don’t classify themselves as a ‘business’, such as a not-for-profit organisation outside the public sector, may be subject to the regulations. The date for assessing if an organisation fits the qualifying criteria is 31 December 2014, and compliance with ESOS is then expected by 5th December 2015.   

What do they have to do to comply with ESOS?

To comply with ESOS regulations the organisation will need to undertake an ESOS Assessment covering all their UK operations over a 12-month period, including the 31st December 2014. What they need to do:

  • Appoint a ‘Lead Energy Assessor’ to oversee their ESOS Assessment.
  • Measure the total energy consumption for buildings, industrial processes and transport.
  • Identify areas of significant energy consumption that account for at least 90% of total energy consumption.
  • Identify practical energy efficiency recommendations for areas of significant energy consumption and assess and report on the cost-effectiveness of each.
  • Report compliance to the Environment Agency by December 5th 2015, after having had the ESOS Assessment reviewed by a Board-level Director and approved by a Lead Energy Assessor.

ESOS Energy Audits must be carried out or reviewed by a suitably qualified Lead Energy Assessor; as this provides organisations with assurances that the savings identified are real and achievable.
