ESOS Phase 2 Audits: Must-Have For All Large Companies

27th August 2019

Over 250 employees? Or £45m turnover? You need to do an ESOS energy audit.

The UK Government requires you to commission an energy audit of your assets under its ESOS (Energy Savings Opportunity Scheme) programme. We’re going to tell you what it is and how it’s done.

The idea is that ‘large undertakings’ assess their energy consuming assets and determine where energy efficiencies can made, the energy saving measures that we establish are not mandatory but the energy audit is, it needs to be completed and the Environment Agency informed by 5th December.

The process involves our energy specialists undertaking a Level 1 energy audit; we visit the site, look at all plant and equipment and have a walkthrough the occupied areas to gather information on the building. We will also have a brief interview with 1 or 2 of the building personnel to understand how the building is being used. The whole site visit typically takes no more than half a day, with the rest of the analysis being completed by us at our offices.

Through the site visit and subsequent analysis we can identify areas of energy waste or inefficiency. We will provide a report which analyses where the energy is being used and detailing low-cost/no-cost measures to save energy and potential capital improvements that can save more energy. We tend to only consider energy savings that payback in less than 7 years or within the duration of the lease, whichever is lowest. Our audit will uncover any major problem areas and provide corrective measures with estimates of implementation costs and potential cost savings.

We undertook an energy audit for a large office with multiple different heating and cooling systems. The energy saving opportunities identified were:

  • Reduced ventilation hours to match essential occupancy.
  • Relaxing of cooling set point by 1 degree Celsius.
  • Re-lamping of halogen bulbs throughout the offices.
  • Installation of PIRs in hallways.
  • Optimisation of BMS schedules.
  • Switching of energy supplier.

All of the measures above resulted in a year 1 saving of over £30,000. No opportunities were chosen if they had a payback of greater than 5 years.

It should be noted that all ‘large undertakings’ must have the energy audit completed by the 5th December and the UK government has the power to fine companies up to £90,000, in fact last year eBay UK Ltd was fined £12,150 for non-compliance, so it’s best to make a start on this now to avoid time and money next year. It doesn’t have to be a burden; we endeavour to make the process as pain-free as possible and do our upmost to match the consultancy cost to the potential energy saving so not to leave the client out-of-pocket.

Come and speak to us, we can take you through the process and start making cost savings on your organisation’s energy bills within the year. Feel free to contact Eduard or Chris directly.
