How to Reduce UK Business Energy Costs
If your business, like many others in today’s market, has been impacted by rising energy costs, you are not alone. With various geopolitical and economic factors at play, costs surrounding energy consumption are a significant portion of a business’s running costs.
When looking to reduce UK business energy costs, businesses often look at their energy contract as first priority. However, the price paid per unit is only part of the equation.
Businesses need to understand why, when, and where their energy is being consumed before deciding what needs to be changed. A commercial energy audit provides this starting point, offering practical, prioritised actions for reduction.
What Is a Commercial Energy Audit?
A commercial energy audit is a structured review of how your business uses and pays for energy. It is designed to look deeper into all aspects of your energy, including consumption, equipment, operating patterns and costs to identify where energy may be wasted and where improvements can be made.
An energy audit allows your business to:
- Measure your current standing
- Identify areas for improvement
- Prioritise what is commercially viable
- Implement certain changes based on your findings
- Monitor consumption for future improvements
An audit can examine:
- Electricity and gas consumption
- Energy bills and costs
- Operating hours
- Heating and cooling
- Lighting
- Machinery and equipment
- Building performance
- Metering and energy data
- Existing onsite generation

How Does an Energy Audit Help Reduce Costs?
1. Understanding Where Your Energy Is Being Used
An audit undertaken by an energy consultancy gives you a comprehensive understanding of where your energy is going. By establishing your current position, you can identify where you are able to improve, using both low-hanging fruit and longer-term solutions to your business’s energy cost reduction strategy.
As Energy Consultancy of the Year, Advantage Utilities puts it, “you can’t manage what you can’t measure”.
To put it simply, an audit determines:
- How much energy is being consumed
- When it is being used
- Which buildings, processes or sites consume the most
- Any unnecessary out-of-hours usage
- Unexpected changes or patterns
For multi-site businesses, this can also involve comparing similar sites to identify unusually high consumption.
2. Identifying Energy Waste and Opportunities for Savings
Using the information from the audit, an energy consultancy can identify some realistic areas for improvement, for example:
- Heating and cooling
- Lighting
- Machinery and equipment
- Out-of-hours consumption
- Building controls
- Inefficient equipment
- Onsite generation opportunities
Overall, an energy audit will uncover opportunities for energy consumption reduction, lowering your carbon footprint, and ensuring compliance. It may also suggest renewable energy solutions and long-term strategies to enhance operational efficiency and sustainability.
