Why Is My Business Energy Bill So High? 10 Things to Check

If your business energy bill has suddenly increased, you're not alone. Energy costs remain a significant overhead for businesses across the UK, and even a relatively small increase in electricity or gas prices can have a noticeable impact on profitability.

But a higher energy bill doesn't always mean your business is simply using more energy.

Changes in consumption, contract rates, standing charges, billing errors and seasonal demand can all affect what you pay.

The good news is that there are several things you can check before accepting a higher bill as unavoidable.

1. Has your energy consumption increased?

The first thing to check is whether your business is actually using more energy.

Compare your latest electricity and gas consumption with the same period last year. Looking at the number of kilowatt-hours (kWh) used can be more useful than simply comparing the total cost.

Energy consumption can increase because of:

• Longer opening hours
• Business expansion
• Additional equipment
• Increased staffing or customer numbers
• Colder weather
• Changes to heating or cooling
• New machinery
• Seasonal activity

If your consumption has increased significantly, investigate why before focusing solely on the price you're paying.

2. Has your energy contract changed?

If your business energy contract has recently expired or been renewed, check the terms carefully.

Your new contract may have different:

• Electricity unit rates
• Gas unit rates
• Standing charges
• Contract terms
• Additional charges

Even a small increase in the price per kWh can make a substantial difference to a business with high energy consumption.

If your contract is approaching renewal, it's worth reviewing your options early rather than waiting until the existing agreement ends.

3. Check your electricity and gas unit rates

Your unit rate is the price you pay for each kWh of energy.

Check your latest bill against the rates stated in your contract.

If the rate being charged doesn't appear to match the agreed rate, contact your supplier and ask for an explanation.

It's also worth checking whether different rates apply at different times or whether your contract includes charges that aren't immediately obvious from the headline price.

4. Check your standing charges

Standing charges are applied regardless of how much energy your business uses.

For businesses with multiple meters or premises, these charges can add up quickly.

When reviewing your bill, check:

• The daily standing charge
• Whether it matches your contract
• Whether you have multiple meters
• Whether any additional fixed charges have been applied

A business can have relatively stable energy consumption but still see its total bill increase because of changes to fixed charges.

5. Could there be a billing error?

Energy bills aren't always straightforward, particularly for businesses with multiple meters or complex contracts.

Errors can include:

• Incorrect meter details
• Incorrect unit rates
• Estimated meter readings
• Duplicate charges
• Incorrect standing charges
• Incorrect contract information
• Consumption being allocated to the wrong period

If something doesn't look right, don't simply assume the bill is correct.

Energy bill validation can provide an additional check that your invoices match your agreed contract terms and actual energy usage.

6. Are your meter readings accurate?

Where appropriate, compare the meter reading on your bill with the actual reading from your meter.

If your supplier has estimated your consumption, the bill may not accurately reflect how much energy you've actually used.

Regular meter readings can help provide more accurate billing and make it easier to identify unusual changes in consumption.

For larger businesses, smart meters and half-hourly consumption data can provide much greater visibility of energy usage.

7. Is your business using more energy than it needs?

Sometimes the simplest explanation for a higher bill is that energy is being wasted.

Look at the biggest energy users across your premises.

Depending on your business, these could include:

• Heating
• Air conditioning
• Lighting
• Refrigeration
• Commercial kitchens
• Machinery
• Hot-water systems
• Ventilation
• IT equipment

Consider whether equipment is being left running outside operating hours or whether heating and cooling systems are operating when areas are unoccupied.

Small inefficiencies can become significant when repeated every day.

8. Has seasonal demand affected your bill?

Energy consumption naturally changes throughout the year.

Gas consumption can increase substantially during colder months as businesses use more heating and hot water.

Electricity consumption can also change depending on the time of year, particularly where businesses use air conditioning, refrigeration or extended lighting.

Rather than comparing one month's bill with the previous month, look at 12 months of consumption data to identify seasonal patterns.

9. When does your energy contract expire?

If your business energy contract is approaching its end date, now is the time to review it.

Don't wait until the final few weeks.

Starting the procurement process early gives you more time to:

• Review your current contract
• Analyse your energy consumption
• Monitor the energy market
• Compare suppliers
• Consider fixed or flexible options
• Understand your future energy requirements

The best approach will depend on your business and market conditions, but leaving procurement until the last minute can reduce your options.

10. Are you paying a competitive price for your energy?

Finally, ask a straightforward question:

Is your business paying a competitive price for electricity and gas?

Your business may be using energy efficiently but still paying more than necessary because of an uncompetitive contract.

Energy procurement involves more than simply finding the cheapest headline tariff. You need to consider the full cost of the contract, including unit rates, standing charges, contract terms and other applicable charges.

This is particularly important for businesses with significant energy consumption, where even a small difference in the price per kWh can have a substantial effect on annual costs.

How to reduce your business energy bill

Once you've identified why your energy costs have increased, you can start looking at potential solutions.

Improve energy efficiency

Reducing unnecessary consumption can lower your overall energy costs.

Depending on your business, this could involve:

• Switching to LED lighting
• Improving heating controls
• Upgrading inefficient equipment
• Improving insulation
• Optimising refrigeration
• Installing solar PV
• Monitoring energy consumption

The best opportunities will vary from one business to another.

Review your energy contract

If your current contract is coming to an end, compare your options rather than automatically accepting a renewal offer.

Consider whether a fixed or flexible energy contract is appropriate and look at the total cost rather than just the headline unit rate.

Validate your energy bills

Regular bill checks can help identify discrepancies and ensure that you're being charged in accordance with your contract.

This can be particularly valuable for businesses with multiple sites, meters or complex energy requirements.

Monitor your energy consumption

You can't effectively manage energy costs without understanding how much energy your business is using.

Regular monitoring can highlight unusual consumption and help you measure the impact of efficiency improvements.

What if your business energy bill keeps increasing?

If your energy bill continues to rise despite stable consumption, it may be time to investigate your contract and billing in more detail.

Start by comparing:

Current kWh consumption, Previous consumption, Unit rates, Standing charges, Contract terms, Total cost

This should help establish whether the increase is being caused by higher consumption, higher prices or another factor.

For larger businesses, a detailed review of historical consumption and billing data can provide a much clearer picture.

How Energy Costs Managed can help

Managing business energy costs involves more than simply switching suppliers.

At Energy Costs Managed, we help UK businesses take a more strategic approach to energy costs through energy procurement, wholesale price monitoring and energy bill validation.

If your business energy bill has increased, reviewing both your consumption and your contract can help establish where the additional cost is coming from.

You may find that the solution isn't simply to use less energy. It could be that your contract needs reviewing, your bills need checking or your procurement strategy needs changing.

Final thoughts

A higher business energy bill doesn't automatically mean your business is using too much energy.

Before accepting increased costs, check your consumption, unit rates, standing charges, contract terms, meter readings and bills.

Once you understand what's driving the increase, you can make informed decisions about energy efficiency and procurement.

If your business energy costs are rising, don't just pay the bill and move on. Find out why.
