Reduce business energy bills: simple ways for SMEs to cut costs

If you’re looking to reduce business energy bills, you’re not alone. Energy remains one of the biggest overheads for SMEs, and with prices continuing to fluctuate, many businesses are under pressure to stay in control of costs. 

Some of the most recent UK data shows that small businesses pay on average around £2,889 a year for electricity and nearly £950 for gas. And it is not just about cost. According to new research from British Chambers of Commerce, 27% of businesses say they still struggle to pay energy bills, highlighting how important it is to take action. 

The good news is that reducing your energy use does not have to be complicated or disruptive. With a few simple, practical changes, you can start saving money while building a more efficient and sustainable business. 

Why it matters to reduce business energy bills 

Energy is essential to how your business runs. But it is also an area where small improvements can make a real difference. 

Reducing energy consumption can help you: 

• Lower operating costs and protect margins 
• Improve resilience against future price rises 
• Support your journey towards net zero 
• Strengthen your reputation with customers 

It is about being positively pragmatic. Small steps today can build meaningful change over time. 

Quick wins to reduce business energy bills 

Turn off what you are not using 

It sounds simple, but it is often overlooked. Nearly half of business electricity usage can happen outside normal working hours.  

Start with: 

• Turning off lights in unused areas 
• Switching off equipment at the socket 
• Setting clear end-of-day shutdown routines 

These are low effort actions that can deliver immediate savings. 

Switch to energy-efficient lighting 

Lighting is one of the easiest places to cut energy use. 

• LED bulbs use up to around 80-90% less energy than traditional lighting
• Motion sensors can reduce unnecessary usage in low-traffic areas 

This is a quick upgrade with a clear return, especially for offices, retail and hospitality spaces. 

Adjust your heating and cooling 

Heating and cooling often account for a large share of energy use. 

Simple changes include: 

• Setting heating to around 19°C in offices 
• Turning systems on only when needed 
• Reducing temperature by just 1°C, which can cut heating costs by up to 10% 

Comfort matters, but efficiency does too. Finding the right balance is key. 

Smarter ways to manage your energy 

Understand your energy usage 

You cannot improve what you cannot see. 

Tracking your energy use in kilowatt hours (kWh) helps you: 

• Spot unusual spikes 
• Identify waste 
• Make more informed decisions 

Smart meters and regular bill reviews can give you clearer visibility and more control. 

Carry out an energy audit 

An energy audit helps you understand where your business is using energy and where it is being wasted. 

This could highlight: 

• Inefficient equipment 
• Poor insulation 
• Opportunities for quick savings 

Many businesses find that even basic audits reveal simple fixes that quickly reduce costs. 

Upgrade equipment over time 

Older equipment often uses more energy than necessary. 

As you replace or upgrade, look for energy-efficient options such as: 

• Modern HVAC systems 
• Energy-rated appliances 
• Efficient IT equipment 

While there can be upfront costs, these upgrades often pay back over time through lower bills. 

Longer-term ways to reduce business energy bills 

Improve your building efficiency 

Your business premises play a big role in how much energy you use. 

Consider: 

• Improving insulation 
• Sealing drafts 
• Installing energy-efficient windows 

These changes help maintain temperature and reduce the need for heating and cooling. 

Explore renewable energy options 

For some SMEs, generating your own energy can be a longer-term solution. 

Options include: 

• Solar panels 
• Battery storage 
• Green energy tariffs 

This can help protect your business from price volatility while supporting a more sustainable future. Our range of renewable energy products gives you the option to power your business with 100% renewable electricity from sources like wind, solar and hydro, with flexible contracts designed to suit how your business uses energy.

• You are on the right tariff for your usage

Working with a supplier that offers flexible, transparent solutions can make this process much easier.

Build an energy-aware culture 

Technology and processes are important. But people are at the heart of every business. 

Encourage your team to: 

• Be mindful of energy use 
• Follow simple energy-saving habits 
• Share ideas for improvement 

When everyone is involved, small actions quickly add up.
