Energy Savings Opportunity Scheme (ESOS)

As we come from an industrial background, we can offer energy audits of industrial equipment and processes, as well as the buildings that house them.

The intention of ESOS is to assist businesses in understanding the potential for undertaking energy saving programs. There is no obligation to implement any of the recommendations but experience shows that cost reduction is a benefit.

The scheme applies to large undertakings and groups containing large undertakings in the UK. An undertaking, as defined in the Companies Act 2006, is:

  • a corporate body or partnership
  • an unincorporated association carrying on a trade or business, with or without a view to profit
A large undertaking is any UK undertaking that meets either one or both of the conditions below on 31st December 2014:
  • it employs 250 or more people
  • it has an annual turnover in excess of £38,937,777 (50 million euro); and an annual balance sheet total in excess of £33,486,489 (43 million euro)
You also must take part in ESOS if your undertaking is part of a corporate group which includes another UK undertaking that meets either of these two conditions.

Where a corporate group participates in ESOS, normally the highest UK parent will take on responsibility for ensuring the group as a whole complies.

The UK registered establishment of an overseas company will also need to take part in ESOS, regardless of its size, if any other part of its global corporate group activities in the UK meets the ESOS qualifying criteria.
