An energy audit is a detailed assessment of energy use across buildings, transport, and processes, identifying inefficiencies and recommending improvements. It uncovers opportunities to reduce costs, optimise efficiency, and minimise carbon footprints, supporting compliance and net-zero goals with actionable strategies.

The Energy Savings Opportunity Scheme (ESOS) is a mandatory UK programme requiring large organisations to conduct energy audits every four years, covering buildings, processes, and transport. These audits identify energy-saving opportunities, enhance efficiency, and ensure compliance. Non-compliance may result in substantial fines.

Qualification Criteria:

1. 250 employees or more or
2. Annual turnover exceeding £44 million (€50 million ) and
   Balance sheet total over €43 million (£38 million)

A Net Zero Pathway (NZP) is a plan to achieve net-zero emissions by reducing energy use, adopting renewables, and offsetting remaining emissions. It aligns organisations with the UK’s 2050 targets, enhances sustainability, and reduces costs. Energy audits support NZPs by identifying inefficiencies and opportunities to cut emissions effectively.

A Heat Decarbonisation Plan (HDP) is a strategy to transition heating systems from fossil fuels to low-carbon options like heat pumps or district heating. It helps organisations reduce emissions, lower energy costs, and meet net-zero targets. Energy audits support HDPs by assessing current systems, identifying low-carbon opportunities, and providing insights for effective implementation.
