ESOS Phase 4: Stay Ahead of New Requirements

One of the most significant updates for ESOS Phase 4 is the postponement of mandatory net zero requirements to Phase 5 (2027-2031). However, you can voluntarily include net zero planning in your Phase 4 assessment, giving your business a head start on future regulations.

Additionally, ESOS now requires you to track progress on your action plans and report whether energy-saving measures have been implemented.

The qualification date remains 31 December 2026, with compliance reports due by 5 December 2027. If your business qualifies for Phase 3, you’ll still be eligible under Phase 4, as the thresholds remain unchanged.

Avoid last-minute compliance stress, maximise energy-saving opportunities, and take control of your energy efficiency strategy now. Acting early gives you the time to implement meaningful changes before audits begin—putting you ahead of the curve.

Our specialists provide expert guidance on ESOS Phase 4 requirements, handle energy audits and reporting, and create tailored action plans to improve sustainability while reducing costs.

Benefits of Conducting Energy Audits

Cost Savings and Efficiency


Conducting commercial energy audits helps businesses uncover areas of energy wastage, allowing them to cut costs by improving energy efficiency based on audit recommendations.

Environmental Impact


Commercial energy audits help businesses reduce their carbon footprint by identifying ways to decrease energy consumption, supporting corporate sustainability objectives, and ensuring compliance with environmental regulations.

Improved Operational Performance


Energy audits for businesses frequently reveal operational inefficiencies, which, when addressed, can enhance productivity and operational performance by ensuring optimal equipment and system functionality.

Types of Commercial Energy Audits

Key Focus Areas in Energy Audits

Lighting Systems

Upgrading energy-efficient lighting systems like LEDs can significantly reduce energy consumption and costs.

HVAC Systems

Optimising heating, ventilation, and air conditioning (HVAC) systems can save energy.

Industrial Processes

Improving the efficiency of processes and machinery in manufacturing and industrial settings can lead to significant energy savings.

Building Envelope

Enhancing building insulation and sealing helps maintain optimal temperatures, reducing the need for excessive heating or cooling.

Steps Involved in an Energy Audit

Our energy assessors will evaluate the building's envelope, including windows, doors, and other openings, to determine if energy is lost through these points. They will also review operational and management practices.

1. Initial Meeting

The process begins with an initial meeting to understand the client's objectives, operations, and energy usage patterns. This step is essential for defining the scope of the audit.

2. Data Collection

Data collection involves gathering historical energy consumption data, equipment specifications, and operational schedules. This information is crucial for analysing energy usage.

3. On-Site Inspection

An on-site inspection is conducted to observe and measure the energy performance of equipment and systems. This step includes using specialised tools to gather accurate data.

4. Data Analysis

The collected data is analysed to identify energy-saving opportunities. This involves comparing current energy usage with industry benchmarks and best practices.

5. Reporting

A detailed report summarises the findings and provides recommendations for energy efficiency improvements. This report includes a cost-benefit analysis and an implementation plan.

6. Implementation

Businesses may require support to implement the recommended changes after the audit. This could involve project management, training, and ongoing monitoring.
