What is a Business Energy Audit?
A business energy audit is a careful check of organisational energy use. It reviews energy use, highlights wasted energy, and finds energy saving opportunities. Analysis of equipment, systems, and operational behaviours provide a full energy view.

- prioritise and justify investment

Business energy audits form a key part of an energy management strategy or energy efficiency consulting. They can support business energy monitoring and inform your net zero strategy. They help you create real action to achieve net zero emissions.

ESOS (Energy Savings Opportunity Scheme) is run by the Environment Agency. Complying businesses need an external Energy Audit (by a qualified lead assessor) in each 4 year period.
Each compliance period (Phase 4 runs until 5 December 2027 – the compliance date) requires businesses to get an external energy audit and identify energy saving opportunities.
The ‘qualification dates’ for Phase 4 is 31 December 2026. That means if your business meets the criteria on the compliance date, you need to submit an ESOS return to the EA.
Companies that need to comply with ESOS Phase 4 are those who have 250+ employees in the UK, OR an annual turnover over £44 million and a balance sheet over £38 million.
If you have had to comply with ESOS before, but no longer meet the criteria on the compliance date, get in touch to check whether you need to complete a return.
ESOS can offer a huge amount of value to your business and your sustainability strategy. You can complete your Energy Audit at any point in the compliance period. This can be a useful way to make it work for you – you don’t have to wait for 2027! If you’re looking to upgrade your offices or examine your Net Zero action plan, it could support you in the process.
Costs vary depending on the size and complexity of your premises. If you are pursuing compliance with ESOS Phase 4, you will usually save money by completing your audit earlier in the compliance cycle.
The level of Energy Audit will also impact the cost – our Investment Grade audts usually build on an initial Energy Audit.
