Working out how much you’re paying for your business energy can be complex but scrutinising your bills and invoices is vital to make sure you aren’t being overcharged.
The energy advisers we work with can help you with your calculations and pinpoint where savings can be made, but on this page, you will find a handy business energy calculator you can use as a starting point for estimating your gas and electricity costs.
Calculate your business energy costs
You can use our business energy calculator below to work out how much your company’s gas and electricity costs are, regardless of whether you have an energy bill to hand.
If you have your bill, this tool can offer precise data showing how much you’re paying per month and annually, based on exact usage, unit rate, and standing charge.
Our calculator can also provide a benchmark estimate of your business gas and electricity costs based on your company size and energy type, if you don’t have a bill to hand.
Give it a try below and feel free to reach out if you need some advice about your bill.
How this calculator works
The calculator can help businesses work out how much they are paying for their gas and electricity each month and annually. The way it works depends on whether you have a commercial energy bill you can refer to for precise data to input into the tool…
-
With an energy bill: Select whether you want to calculate your electricity or gas costs, then input your usage, unit rate, standing charge and VAT rate.
-
Without an energy bill: Choose either electricity or gas calculations then select your business size and sector from the dropdown menus as well as a VAT rate.
Once you have entered this information, our calculator will then provide a breakdown of your business energy costs per month and annually. You can also apply the energy efficiency discount you can claim if you reduced your usage by 10% to see how your bill changes.
Why use our business energy calculator?
Getting clarity on your energy costs is essential for budgeting as a business, managing your finances and identifying where money can potentially be saved.
If you have received an energy bill for the month and have it to refer to, this calculator is useful for cross-checking the amount against your contract and meter readings to ensure it is correct, and get an idea of what it will work out as across the whole year.
Our business energy calculator is also handy if you are shopping around for a new gas or electricity deal. You can use it to estimate what you are currently paying and compare it against average rates that appear on comparison sites and broker portals, and any deals suppliers might offer you directly to get a feel for how much you would be saving.
After using our calculator, you can get advice about your energy bill - including bill validation and guidance on whether you should switch providers - by booking a free, no-obligation consultation with one of our independent commercial energy consultants below.

FAQs
Several variables influence the final figure on your bill, which is why business energy is often more complex than domestic energy. Key factors include:
-
Business Size and Sector: Larger companies typically have higher consumption, but may access lower unit rates due to their high volume.
-
Usage (kWh): The total amount of gas or electricity you consume is the largest driver of your costs.
-
Unit Rate: The price you pay for every kilowatt-hour (kWh) of energy used.
-
Standing Charge: A fixed daily cost that covers the maintenance of the energy network and the supply to your premises.
-
Location: Costs can vary depending on which regional network your business is connected to.
-
VAT and Levies: Most businesses pay 20% VAT, though some may qualify for a 5% reduced rate. You may also be subject to the Climate Change Levy (CCL).
