What is the average business energy bill?

UK businesses have faced a challenging few years. Just as they reopened their doors following the coronavirus crisis, businesses were slammed by historically high energy prices. While energy markets have stabilised somewhat, they remain elevated in 2025.

Average business energy bill totals are hard to arrive at, given the huge range of energy consumption patterns across industries and company sizes. The energy demand of a small shop or hairdresser will radically differ from that of a chemical manufacturer. More pertinent are the average per-unit rates and standing charges businesses are currently paying for their gas and electricity, which are detailed below.

What is included in business energy bills?

You may quickly bin your business energy bill when it arrives, especially if your company has a direct debit set up to pay the charges. But if you study your monthly bill, you’ll find out important information that will help you stay on top of your energy contract and potentially save you money.

Every business energy bill will contain the following:

  1. 1

    Bill date and number

    At the top of the page you’ll find the date the bill was issued and a number that helps the supplier identify the specific bill if you raise a query about it.

  2. 2

    Your business’s account number and VAT number

    You’ll need to quote your account number if you contact the supplier. You may also use the account number to log into your supplier’s online portal or mobile app to manage your account. The bill will also state the registered VAT number the supplier has on record for your business. If it's incorrect, you may be paying too much or too little in VAT.

  3. 3

    Contact information for the supplier

    So you can raise any questions you might have about the bill.

  4. 4

    Information about your contract

    Including the type of tariff (fixed, variable, flexible, etc.) and the date it will expire or auto-renew. This supplier should also include information about how to contact them to discuss your contract.

  5. 5

    The billing period

    The period of consumption the bill covers. This is usually a month but may be three months if your business is billed quarterly.

  6. 6

    Whether your charges are actual or estimated

    Actual charges are based on meter readings you’ve supplied or the supplier has taken. Estimated bills are extrapolated from your previous use. However, the estimates may not be correct and you could be either overpaying or underpaying, meaning you could be hit with a larger bill down the line.

  7. 7

    Balance from your last bill

    The supplier will state your charges from your last billing period, any payments received, and any amount you still owe or credit in your account.

  8. 8

    Charges for this billing period

    Usually this will be broken down into charges for use and total standing charges for the period. On the reverse or second page of the bill, you’ll find details of these charges, including meter readings you’ve submitted or have been estimated, the total number of units of gas or electricity used, and your per unit rate.

  9. 9

    VAT charges

    This is usually a 20% tax but is 5% for some organisations.

  10. 10

    Total amount owed

    This is the amount you must pay, including any outstanding balance from your previous bill, charges for this period, and VAT. The bill will also state the date your payment is due. If you don’t pay by this date, your supplier may levy late charges.

  11. 11

    MPAN or MPRN number

    The MPAN is a 21-digit number used to identify your electricity supply point. The MPRN is an 11-digit number used to identify your gas supply point. You may occasionally need these numbers when speaking with your supplier about your account. On rare occasions, these numbers are incorrect, which may lead to you paying for the energy consumption of another property. If your bills seem inaccurate for your usage, speak to your supplier to ensure your MPAN or MPRN match your address and meter.

What makes up the cost of my business energy bills?

The amount you owe your energy company will include:

Charges for your use

This is calculated by multiplying your usage by your per-unit rate. Multiple energy supplier costs go into per-unit rates, as we’ll discuss below.

Standing charges

These are flat charges, levied daily, to cover the maintenance and repair of the electricity or gas grid, the servicing of your account, and government social and environmental schemes.

If you’re facing a spike in energy bills, as many businesses have recently, you might be wondering how suppliers set their per-unit rates and standing charges. Many energy company costs feed into the prices you pay, including:

  • £

    Wholesale energy costs (33% of your energy bill)

    The cost of generating or procuring the electricity and gas you use on the wholesale markets.

  • £

    Network costs (25%)

    These costs cover the operation, maintenance, and upgrading of the electricity grid and gas pipes that bring energy across the country and into your business. Network companies charge energy suppliers a regulator-set price to use this energy network, a cost that is then passed onto energy consumers including your business.

  • £

    Social and environmental obligation costs (25%)

    Large energy suppliers are required to contribute to government schemes, including those that fund energy efficiency upgrades in homes and businesses, assist vulnerable households with their heating bills, and support the uptake of renewable energy and technologies.

  • £

    Operating and margin costs (16%)

    Energy suppliers have their own costs, including for customer service and billing. They also set their prices with a margin for profit.

  • £

    Other costs

    These include costs for installing and reading meters, including the £13.5 billion rollout of smart meters.

What is the average business gas bill in the UK?

Natural gas prices have stabilised recently, although they remain elevated compared to before 2021, reflecting ongoing tensions with Russia, formerly a major supplier of gas to Europe.

The rates businesses pay for natural gas vary widely, depending on their usage, size, contract type, and supplier. Typically smaller businesses with lower consumption pay higher per-unit rates but in return have lower standing charges. Large businesses benefit from lower per-unit rates, reflecting their bulk usage, but have higher standing charges. Standing charges also vary by region, as they’re linked to maintenance of local gas infrastructure.

Typical rates and bills for natural gas, as of the summer of 2024, are as follows:

Business type

What is the average business electricity bill in the UK?

With a third of Britain’s electricity generated by natural gas, electricity prices have had the same wild ride as natural gas prices recently: spiking to unprecedented levels in 2022 and then stabilising a lower, but still elevated, level.

The rates businesses pay for electricity and their overall bills vary greatly, depending on their consumption, size, contract type, supplier, and region.

How to reduce your business energy bill

Your business’s energy bill will likely form a significant part of your annual expenditure. While you can find savings by switching business energy suppliers and locking in cheaper rates with a fixed tariff, you’ll make the biggest dent in your bills by reducing your consumption. Greater energy efficiency will also insulate your business from future turbulence in the energy market and reduce your carbon footprint, a big pull for environmentally-conscious consumers and clients.

  1. 1

    Conduct an energy audit

    An energy audit will identify where and at what times you’re using energy and help you home in on potential changes. A smart meter, displaying your energy usage in real-time, can assist with this audit.

  2. 2

    Don’t leave electrical equipment on standby

    A sleeping computer still uses electricity. Turning it off entirely at night and over the weekend can reduce its annual energy use by 75%, according to the Carbon Trust.

  3. 3

    Use energy efficient appliances

    Although more efficient energy appliances are often more expensive upfront, the energy bill savings will pay for themselves. If you don’t have the budget to replace ageing appliances, having them regularly serviced can ensure they’re operating as efficiently as possible.

  4. 4

    Make your lighting efficient

    Lighting your office space could account for 40% of your business’s energy bill, EDF says. To reduce this usage, switch to LED and lower-wattage bulbs and energy-efficient lighting fixtures. Remind your staff to turn off lights when they leave the rooms and overnight. Motion sensors can correct human error and ensure you’re not lighting empty rooms.

  5. 5

    Watch your thermostat

    You’re likely overheating or over-cooling your premises, inflating your energy bills. Turning down your heating by just 1 degree Celsius could reduce your energy bill by 10%. A programmable thermostat can guarantee you’re only heating the spaces you need when you need them. For instance, the thermostat could be set to turn on the heat an hour before your employees arrive and turn it off after they depart.

  6. 6

    Go paperless

    Printers and copiers are electricity-hungry. A photocopier left on standby all year, even on nights and weekends, could use £63 of electricity a year. Keeping those emails digital saves not just paper but also electricity.
