What do you need to do to compile Phase 3 data?

To make sure you process your Phase 3 data on time, you need to:

  1. Compile your energy consumption covering 12 months, including the qualification date of 31st December 2022 and summarise audit reports and energy data.
  2. Complete necessary audits.
  3. Finalise the report, obtain senior management or board level sign-off, register relevant consumption data and report findings with the Environment Agency before the 5th December 2023 deadline.

And to help you track and submit your data on time, we’ve created this handy 5-step guide:

Step 1: Allocate a Lead Process to the project

You should do this by December 2022. You cannot file an ESOS report without an accredited Lead Assessor.

Step 2: Evaluate and measure energy consumption

Measure your total energy consumption, including business travel and processes. Ensure your data is accurate to justify your strategy and demonstrate how much your energy consumption is reducing.

Step 3: Audit all areas of significant consumption

When reporting, you can leave out 10% of your consumption by categorising it as ‘de minimis’, but you must audit the rest to be compliant. Note: This may change to 5% as a result of the latest government consultation.

ESOS Energy Audits are the most common choice for completing this. However, depending on how many sites your business owns or operates, you may not have to complete surveys for them all.

Other options include ISO 50001 and Display Energy Certificates (DEC), although these may be removed from future phases.

The most effective audits should assess HVAC systems, controls, lighting, and building fabric and use the latest equipment, like thermal imaging and air leakage.

Step 4: Identify how to reduce energy consumption

While there is no obligation under ESOS to act on any audit recommendations, it makes sense to do so with energy prices soaring. Savings of between 5% and 15%  can be made by monitoring data and implementing simple maintenance or activity changes.

LED lighting can bring an ROI in less than 12 months, while projects with a higher upfront cost are recommended, including solar/EV heat pumps.

Step 5: Notify the environment agency in good time

For maximum benefit, we recommend you promote recommendations throughout your business as a part of an internal energy management programme.
