Commercial Energy Audits

Cut costs, improve efficiency and stay compliant with affordable, expert-led energy assessments

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 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.

How much does an energy audit cost?

Costs depend on the size and complexity of your site, as well as the scope of the assessment required. We are one of the most affordable providers in the UK and guarantee to beat any like-for-like quote, even if you have already received one.

Benefits of conducting energy audits

Cost savings and efficiency


Conducting commercial energy audits helps businesses identify areas of energy waste, allowing them to cut costs by improving energy efficiency in line with 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.

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 consultation

The process begins with an initial consultation 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.

Matthew from Focus Green played a significant role in helping us, a small charity, secure a significant grant that will potentially save us thousands of pounds annually, whilst significantly reducing our carbon emissions. He offered advice and support when we struggled with detailed information regarding energy and energy use. Always on hand and quick to respond, we could not have asked for more.

KDYT Wyre Forest

Our local charity was successful in getting an energy survey completed by Focus Green Ltd. From the outset, they have been ultimately professional and produced a report that will allow us to hopefully improve the efficiency of the hall. Following the excellent strategy call, which was very informative, we have just started the process of obtaining quotes for the recommendations made in the survey. So far, so good and I hope that Focus Green will continue to provide us advice and assist us from the tenure of our energy improvements.

Charlton Hall

We made contact with Focus Green to enquire about different avenues for environmental best practise/compliance.
Matt was very helpful and knowledgeable on everything we asked. If FG couldn't do it themselves, they have trusted partners they work with which could be handy.
Overall, very happy with the interaction :)
