We support ESOS Phase 3 and ESOS Phase 4 compliance through structured energy audits, including ESOS reporting, Action Plans, and Progress Reports, helping your organisation reduce costs, strengthen compliance, and improve long-term operational efficiency.

What is a business energy audit?

An energy audit delivers a structured overview of how your organisation uses energy across sites and operations. By identifying inefficiencies and waste, businesses can reduce consumption, lower costs, and improve environmental performance.

Is a business energy audit a legal requirement?

For larger organisations, regulations require an energy audit if you employ 250 or more people, or exceed £44 million turnover and £38 million balance sheet. Acting early protects compliance and avoids last-minute pressure.

What types of energy audits are available?

Energy audits can be tailored to your organisation, from focused single-site reviews to comprehensive multi-site assessments. They also support ESOS Phase 3 and ESOS Phase 4 compliance, including structured Progress Reports and detailed Action Plans.

What’s included in a business energy audit?

A business energy audit includes key actions such as managing compliance, mapping overall energy consumption, pinpointing high-usage areas, and identifying practical opportunities to improve efficiency and reduce operational costs.

How does an energy audit work?

An energy audit helps meet regulatory requirements while identifying savings opportunities. It involves appointing an assessor, reviewing electricity, gas and fleet usage, identifying improvements, gaining director sign-off, and notifying the Environment Agency of compliance.

Who is qualified to conduct an energy audit?

Energy audits must be completed by accredited professionals with recognised expertise in energy efficiency and management. With extensive commercial energy experience, our specialists provide tailored advice and practical, results-driven solutions for your business.

What can I expect from my energy audit?

Your audit will identify practical ways to reduce energy costs, cut carbon emissions, and maintain compliance. It can also highlight renewable energy options and longer-term strategies to improve operational efficiency and strengthen sustainability performance.

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.
