What you need to know about ESOS

The EU Energy Efficiency Directive is a piece of legislation aimed at improving energy efficiency within businesses and, as of December 2015, requires that most organisations carry out an energy audit every four years. To set this in motion, the UK Government has implemented the Energy Savings Opportunity Scheme (ESOS). The scheme's purpose is to audit participating organisations' energy consumption over twelve months to highlight savings opportunities, assisting firms with reducing their carbon footprint and, subsequently, their operating costs. Once identified, participating firms receive recommendations for more energy efficient and cost-effective measures, as well as details of predicted costs. Registration to take part in ESOS started in December 2014.

The EU legislation states that medium-sized organisations and bigger must undertake energy audits every four years. If your UK-based fleet meets one of the following criteria, you are required to conduct an audit and may be eligible to participate in ESOS:

  • You are part of a broader organisation that satisfies either of the
The UK-leg of an overseas company can also partake, assuming their UK activities meet the above qualifying criteria. 

Does all energy consumption fall within the scope of an audit?

An energy audit takes into account all energy bought and consumed by an organisation across all assets and activities. This includes the energy used in transportation, which is why reducing your fleet’s carbon footprint should be a priority. 

That said, the benefits of taking part are huge; not only will it help you comply with European standards, but the resulting recommendations could help your organisation make valuable savings and reduce consumption.
