Learning to understand key terms and charges contained in your business energy bills can help you gain greater insight into the best ways to power your business.

Business energy bills contain a lot of information which can initially seem confusing, but learning how to interpret these details can be helpful in understanding exactly how much your business pays across energy.

Domestic versus business energy bills

The power that runs through your sockets at home comes from the same power supply that turns on your computer at work, but you’ll find differences in pricing structure and contract details for domestic and non-domestic premises in the way your business is billed.

All energy bills include many separate charges, particularly for electricity. While domestic customers will often see only a fixed cost per kilo-watt hour on their bills, businesses will usually receive a more detailed breakdown of charges from their supplier.

What’s included on your business energy bill?

The layout of your utility bill and the terminology varies between energy suppliers, but key account information remains the same. The following items commonly appear on business electricity and gas bills:

Invoice type & period

This shows whether your utility bill is for gas or electricity and the period for which you are being charged.

Payment due date

The date you need to have paid your latest bill.

Contract details

This section contains your contract end date.

Account number & VAT number

If your business is VAT registered, you’ll usually pay 20% as a business owner while domestic customers incur 5%.

Your Standing Charge

What charges are included in business energy bills?

The two main costs that make up your energy bill are the unit cost (the amount you pay per unit of gas or electricity measured in kWh) and the Standing Charge. However, there are a number of other costs that contribute the amount you pay overall. These include:

Business energy wholesale costs

The wholesale cost refers to the amount the supplier pays to buy the energy in bulk from power stations before selling it to customers. You won’t see the wholesale cost on your bill, but it contributes to your unit rate.

Unless you’re on a fixed rate tariff (where you pay an agreed rate for each unit of energy over a set term), your energy bills will usually rise along with wholesale costs.

Transmission Use of System charges (TNUoS)

This is charged to cover maintaining and upgrading the National Grid. It is usually included in the standing charge.

Paying for Distribution Use of System (DUoS)

Distribution Network Operators (DNO) are licensed by Ofgem to distribute electricity in your area. The DUoS charge covers the costs incurred by your DNO and varies according to the contract and meter type have, along with your location and time of use.

Climate Change Levy

The Climate Change Levy (CCL) is an environmental tax which was introduced by the government to encourage businesses to become more energy efficient and reduce carbon emissions.

This cost is charged per unit of energy and will be factored into your overall energy bill.

How can I pay my business energy bill?

Direct Debit

Many suppliers offer a discount if you choose to pay your energy bills by monthly or quarterly direct debit. You’re likely to consume more energy during the winter months, so any credit accumulated across the summer could help to cover increased usage.

BACS or Bank Transfer

This option enables you to make your payment by BACS or online bank transfer on receipt of your bill. This means you know exactly how much you’re paying, but you’ll need to remember to make the payment.

Cheque or Giro

Some suppliers still allow customers to pay for energy by posting a cheque, but you need to allow time for your cheque to arrive to avoid paying late fee penalties. Alternatively, your energy bill may have a giro bank slip attached which you can take to your local Post Office to make the payment.

Frequently asked questions

How are energy bills estimated?

The previous meter reading will be taken from your last bill and subtracted from your current reading. This figure is then multiplied by 2.83 to obtain the volume used in cubic metres. The result is multiplied by the energy contained in the gas or electricity used (the calorific value), which is divided by 3.6 to obtain the number of kilowatt-hours (kWh). Finally, the number of kWh used is multiplied by the pence per kWh rate to obtain the approximate consumption cost.

What affects the price of business energy?

Several factors can affect the wholesale price of business energy, including the weather, storage, regulatory pressures, crude oil prices, flow and availability, and wind generation.

How can I reduce my energy costs?
