Energy Savings Opportunity Scheme (ESOS)

How we help

At Swan Energy, we help clients gain the most out of the Energy Savings Opportunity Scheme (ESOS), which is a mandatory energy audit scheme for all non-SME (small and medium enterprises) - that is organisations with 250 or more employees (in the UK or abroad) and either an annual turnover of €50m (£38,937,777) or more, or an annual balance sheet of €43m (£33,486,489) or more.

We see ESOS not as more red tape, but as a real opportunity to get energy efficiency on the boardroom agenda and reduce the amount of money spent on energy, freeing it up for investment in your core business and ultimately improve your bottom line.

Swan Energy has over 55 years' experience in providing energy management services to industry, commerce and the public sector, including a wealth of experience in energy auditing. We also have an accredited ESOS Lead Assessor in our team and so can take your organisation through ESOS from beginning to end.
