Business electricity can be a significant operating expense, particularly for businesses that rely heavily on lighting, refrigeration, heating, machinery, computers or other electrical equipment.
The good news is that reducing your electricity costs does not always require major investment. Businesses can often make meaningful savings by combining better energy efficiency, smarter electricity usage and regular contract reviews.
Your electricity bill is influenced by more than simply how many kilowatt-hours (kWh) you consume. Business energy costs can include wholesale costs, network costs, environmental costs, taxes, standing charges and supplier-related costs.
This means there are two broad ways to reduce your costs:
- Use less electricity
- Pay less for the electricity you use
The most effective strategy is usually to work on both.
In this guide, we’ll explain practical ways to reduce business electricity costs, from improving energy efficiency and changing business habits to reviewing your tariff and comparing suppliers.
What Are Business Electricity Costs?
Business electricity costs are the total costs associated with supplying and using electricity at your premises.
Your electricity bill can include:
- Electricity unit charges
- Standing charges
- Network costs
- Government schemes and levies
- Taxes
- Supplier costs
- Metering-related charges
- Other applicable charges
The exact details depend on your business, meter, supplier and contract. Ofgem notes that business energy bills can contain different costs depending on the type of contract and meter being used.
This is why simply reducing your electricity consumption isn’t the only way to lower your overall energy bill.
1. Review Your Current Business Electricity Tariff
One of the first things you should do is check the electricity contract you’re currently paying for.
Look at:
- Unit rate
- Standing charge
- Contract end date
- Contract length
- Exit fees
- Payment terms
- Additional charges
- Renewal terms
A business could have relatively efficient premises but still pay more than necessary because it is on an unsuitable or expensive tariff.
Ofgem advises businesses to understand their energy contract and compare their options when making commercial energy decisions.
Don’t assume that staying with your existing supplier automatically gives you the best price.
2. Compare Business Electricity Prices
Comparing electricity deals can help identify whether a different supplier or tariff could reduce your overall costs.
When comparing quotations, don’t look only at the advertised unit rate.
Compare:
Unit rate + standing charge + other applicable costs
For example, imagine two hypothetical tariffs:
Tariff A
- 24p/kWh
- 70p daily standing charge
Tariff B
- 25p/kWh
- 40p daily standing charge
Tariff A has the lower unit rate, but Tariff B has the lower standing charge.
Which one is cheaper depends on how much electricity your business consumes.
This is why your annual business electricity consumption is important when comparing contracts.
3. Understand Your Electricity Consumption
Before trying to reduce electricity costs, understand where your electricity is actually going.
Review your consumption over the previous 12 months if possible.
Look for:
- Seasonal changes
- Peak consumption periods
- Unusually high bills
- Weekend usage
- Overnight usage
- Equipment with high electricity demand
- Changes after opening hours
For businesses with suitable metering, more detailed consumption data can help identify when electricity is being used.
Ofgem notes that some businesses have half-hourly electricity readings, allowing suppliers to determine when energy is being consumed rather than relying on estimates.
The more accurately you understand your consumption, the easier it becomes to identify opportunities for savings.
4. Switch Off Equipment When It Isn’t Needed
One of the simplest ways to reduce electricity consumption is to stop using equipment when it isn’t required.
This includes:
- Computers
- Monitors
- Printers
- Kitchen equipment
- Machinery
- Display screens
- Office lighting
- Chargers
- Air conditioning
- Extractor systems
Leaving equipment running overnight or during weekends can create unnecessary electricity consumption.
For example, if equipment does not need to operate outside business hours, establish a clear shutdown routine.
A simple end-of-day checklist can prevent electricity from being wasted repeatedly.
5. Improve Your Business Lighting
Lighting can represent a significant electricity load, particularly in retail stores, warehouses, offices and other large premises.
Consider:
- Replacing inefficient lighting
- Installing LED lighting
- Using occupancy sensors
- Using daylight where possible
- Switching off lights in unused areas
- Creating lighting schedules
LED lighting can use substantially less electricity than older lighting technologies and can also have a longer operating life.
Instead of illuminating an entire building continuously, consider whether different areas can be controlled independently.
6. Use Smart Controls and Timers
Automated controls can reduce the amount of time equipment operates unnecessarily.
Depending on your premises, you could use:
- Timers
- Occupancy sensors
- Motion sensors
- Programmable thermostats
- Smart lighting controls
- Automated heating controls
For example, a storage area may not need full lighting when nobody is present.
Likewise, heating or cooling equipment may not need to operate at the same level outside business hours.
Automation can make energy-saving behaviour more consistent because the system doesn’t rely entirely on employees remembering to switch equipment off.
7. Review Heating and Cooling
Heating and cooling can be major electricity users, particularly in offices, shops and commercial buildings.
Review your:
- Thermostat settings
- Heating schedules
- Air-conditioning settings
- Building insulation
- Doors and windows
- Heating zones
- Cooling requirements
Avoid heating or cooling empty areas unnecessarily.
If your business has multiple rooms or zones, consider whether each area needs to be conditioned to the same level.
Small changes in operating schedules can reduce unnecessary consumption without affecting normal business operations.
8. Maintain Electrical Equipment
Poorly maintained equipment can become less efficient and may consume more energy than necessary.
Regular maintenance can help businesses identify problems with:
- Refrigeration
- HVAC systems
- Motors
- Compressors
- Machinery
- Ventilation systems
- Electrical equipment
For energy-intensive businesses, maintenance can be particularly important.
A refrigeration system, for example, may need to work harder if filters, seals or other components are not properly maintained.
Energy efficiency isn’t only about buying new equipment. Keeping existing equipment operating properly can also help control consumption.
9. Replace Inefficient Equipment
Sometimes the cheapest long-term solution is to replace equipment that consumes excessive electricity.
Potential examples include:
- Old refrigeration units
- Inefficient lighting
- Outdated heating systems
- Older air-conditioning equipment
- Inefficient motors
- Outdated machinery
Before investing, calculate the potential payback.
For example:
Annual electricity savings × expected equipment life
can help you estimate the potential financial benefit.
Don’t replace equipment purely because it is old. Compare the purchase cost with expected energy savings and maintenance costs.
10. Reduce Electricity Consumption During Peak Periods
Some businesses can reduce costs by changing when they use electricity, depending on their tariff and metering arrangement.
For example, certain commercial contracts may have pricing structures that make electricity more expensive at particular times.
If your business has flexible operations, you could potentially move some energy-intensive activities to cheaper periods.
This could apply to:
- Manufacturing
- Laundry operations
- Commercial kitchens
- EV charging
- Water heating
- Industrial machinery
However, don’t assume that off-peak electricity is always cheaper.
Check your actual tariff before changing operating schedules.
11. Consider On-Site Solar Power
Businesses with suitable premises may be able to reduce their reliance on electricity purchased from the grid by generating some electricity themselves.
Solar panels can be particularly interesting for businesses with:
- Large roofs
- Warehouses
- Factories
- Retail premises
- Offices
- Daytime electricity consumption
The economics depend on factors such as:
- Installation cost
- Roof orientation
- Available roof area
- Electricity consumption
- Electricity prices
- Solar generation
- Maintenance
- Financing arrangements
Solar should therefore be evaluated as a business investment rather than assumed to be an automatic saving.
12. Consider Battery Storage Where Appropriate
Battery storage can allow businesses to store electricity and use it later.
It can potentially work alongside solar generation or certain electricity tariffs.
For example, a business could generate electricity during the day and store excess generation for later use.
Battery storage can also be relevant for businesses with particular electricity demand patterns.
However, batteries involve significant upfront costs, so businesses should assess:
- Installation costs
- Battery capacity
- Expected lifespan
- Electricity consumption
- Solar generation
- Tariff structure
- Maintenance
- Financing
A professional assessment can help determine whether the economics make sense.
13. Check Whether Your Electricity Meter Is Suitable
Your meter can influence how your electricity consumption and charges are recorded.
Businesses may have different types of meters, including:
- Smart meters
- Non-half-hourly meters
- Half-hourly meters
- Other commercial metering arrangements
Ofgem notes that the information shown on business energy bills depends partly on the type of meter installed.
If you don’t understand your meter or the information being used to calculate your bills, ask your supplier for clarification.
Better consumption data can help you identify where and when electricity is being used.
14. Prevent Electricity Waste Outside Business Hours
One of the easiest savings opportunities can be hidden outside normal operating hours.
Check whether electricity is being consumed:
- Overnight
- During weekends
- During holidays
- Before opening
- After closing
For example, a business that closes at 6pm but leaves unnecessary lighting and equipment operating until 7am could be consuming electricity for more than 13 hours when the premises isn’t operating.
Create a shutdown procedure covering all major equipment.
For larger businesses, automated controls can make this process easier.
15. Train Employees to Save Energy
Energy efficiency isn’t only a management responsibility.
Employees can influence electricity consumption every day.
Create simple policies such as:
- Switch off lights when leaving rooms
- Shut down computers at the end of the day
- Don’t leave unnecessary equipment running
- Keep doors closed when heating or cooling is operating
- Report faulty equipment
- Avoid unnecessary printing and equipment use
You don’t need a complicated energy programme.
A few simple rules consistently followed across the business can make a difference.
How Much Can a Business Save on Electricity?
There is no universal figure because savings depend heavily on the size and type of business.
A small office with relatively low electricity consumption has a different savings opportunity from a factory operating energy-intensive machinery.
Your potential savings depend on:
- Current consumption
- Electricity tariff
- Business size
- Operating hours
- Equipment efficiency
- Building characteristics
- Employee behaviour
- Existing energy-saving measures
Instead of relying on generic claims such as “save 30%,” calculate potential savings using your own electricity data.

Should You Switch Business Electricity Supplier to Save Money?
Potentially.
Switching supplier can reduce costs if another supplier offers a more competitive overall deal.
However, businesses should check their current contract before switching.
Ofgem says most suppliers will not allow businesses to switch supplier before the end of their contract.
Check:
- Contract end date
- Notice period
- Exit fees
- Current unit rate
- Current standing charge
- New unit rate
- New standing charge
- Contract length
Don’t switch based on a headline rate alone.
Should You Use a Business Energy Broker?
An energy broker can help businesses obtain and compare commercial energy quotations.
This can save time, particularly for businesses that don’t want to contact multiple suppliers themselves.
However, brokers may charge a fee or receive commission.
Ofgem specifically advises businesses to check broker fees and understand the relationship between the broker and energy suppliers.
If you’re considering a broker, ask:
- How are you paid?
- Is there a commission?
- Is there a separate fee?
- Which suppliers do you work with?
- Are all available suppliers included?
- What happens if I don’t accept the quotation?
Transparency is important when comparing business energy deals.
What Is the Best Way to Reduce Business Electricity Costs?
For most businesses, there isn’t one single solution.
The strongest approach is to combine several strategies:
Step 1: Understand Your Consumption
Find out how much electricity you’re using and when you’re using it.
Step 2: Review Your Current Contract
Check your unit rate, standing charge and contract terms.
Step 3: Reduce Unnecessary Consumption
Switch off equipment and improve operating practices.
Step 4: Improve Efficiency
Consider LEDs, controls, efficient equipment and building improvements.
Step 5: Compare Electricity Deals
Check whether another tariff or supplier could provide a lower overall cost.
Step 6: Monitor Results
Continue tracking your electricity consumption after making changes.
This creates a continuous cycle:
Measure → Reduce → Compare → Monitor → Improve
Common Mistakes Businesses Make When Trying to Save on Electricity
Only Looking for a Cheaper Supplier
Changing suppliers won’t solve unnecessary electricity consumption.
If you’re wasting energy, you’ll continue paying for that waste under the new contract.
Only Focusing on the Unit Rate
A lower unit rate can still come with a higher standing charge or other costs.
Buying Expensive Equipment Without Calculating Payback
Energy-efficient equipment can save money, but the initial investment matters.
Ignoring Out-of-Hours Consumption
Electricity used when your business isn’t operating can be an easy area to overlook.
Making One-Off Changes
Energy efficiency works best when businesses monitor consumption continuously.
Assuming Every Energy-Saving Technology Is Worth Installing
Solar panels, batteries and smart systems can be valuable, but the economics differ from business to business.

Business Electricity Cost FAQs
How can I reduce my business electricity costs?
You can reduce business electricity costs by using less electricity, improving equipment efficiency, reducing unnecessary consumption, reviewing your tariff and comparing alternative electricity contracts.
What is the fastest way to reduce business electricity costs?
Start by reviewing your current tariff and identifying unnecessary electricity consumption. Switching off unused equipment, improving lighting controls and reviewing your electricity contract can provide practical starting points.
Does switching business electricity supplier save money?
It can, if another supplier offers a more competitive overall deal. However, businesses should check their current contract, exit terms and the complete cost of the new tariff before switching.
Should I reduce electricity consumption or change supplier?
Ideally, consider both. Reducing consumption lowers the amount of electricity you need to buy, while finding a competitive tariff can reduce the price you pay for that electricity.
Can LED lights reduce business electricity costs?
LED lighting generally uses less electricity than many older lighting technologies, so replacing inefficient lighting can potentially reduce electricity consumption and operating costs.
Can solar panels reduce business electricity costs?
Solar panels can potentially reduce the amount of electricity a business needs to purchase from the grid. Whether installation is financially worthwhile depends on the property’s characteristics, consumption and project costs.
Can an energy broker help reduce business electricity costs?
An energy broker or consultant can help businesses compare commercial electricity quotations, although businesses should understand how the broker is paid and whether fees or commissions apply.
How often should a business review its electricity contract?
Businesses should monitor their contract end date and review their options before renewal. It is also sensible to monitor consumption and costs throughout the contract rather than waiting until renewal.
Final Thoughts
Reducing business electricity costs isn’t simply about finding the cheapest electricity supplier.
The most effective strategy is to look at the whole picture.
Understand how much electricity your business uses, identify where energy is being wasted, improve efficiency and then compare your electricity contract to make sure you’re not paying more than necessary.
For some businesses, the biggest opportunity may be switching to a more competitive tariff. For others, reducing consumption through better lighting, equipment, heating, cooling or operating practices could have a greater impact.
And for businesses with suitable premises and sufficient energy demand, technologies such as solar generation and battery storage may offer additional opportunities.
Start with the basics:
Measure your consumption → reduce waste → improve efficiency → review your tariff → compare your options.
That approach can help turn business electricity from an unavoidable expense into a cost that can be actively managed.
Ofgem’s business energy guidance is a useful reference when reviewing your contract, energy costs and available efficiency support.
Could You Be Paying Too Much for Business Electricity?
Reducing electricity consumption is only part of the equation. Your current tariff could also be affecting your overall energy costs. Compare your current business electricity deal with alternative options and see whether you could find a more competitive rate.
