How much does business energy cost?

When energy suppliers calculate how much you pay for your gas and electricity, several conditions are taken into account, including:

  • Your business address/location
  • The size of your business premises
  • Your current supplier
  • Your current expenditure on business energy
  • Your current consumption of energy (kWhs)
  • Your type of energy meter

Based on the information that you provide us, we will scour the business energy market for you and provide a list of quotes. When comparing quotes and overall prices, have a look at the following:

  • Unit rate (kWh)
  • Standing charges
  • Duration of contract
  • Estimated monthly/annual bill

Business energy deal types

To make sure you’re not being overcharged for your business gas and electricity, it’s important to know the differences between the types of business energy contracts on offer. The five main types of business energy deal are:

Fixed Term

Fixed Term

These deals charge a pre-determined price per unit (kWh) of energy used, which is fixed for the entirety of the contract. However, this doesn’t mean your energy bills will stay the same each month. This will depend on your usage.

Variable Rate

Variable Rate

The price per unit on variable rate energy deals fluctuates depending on wholesale prices. So, if the market price of energy goes up, so will your bills, and vice versa.

Deemed Rate

Deemed Rate

These deals will typically be the supplier’s most expensive tariff, which you will be put on if you don’t negotiate a new deal once your agreed contract ends. To avoid deemed rate tariffs, make sure you compare business energy deals and switch before your current deal expires.



Similar to deemed rate tariffs, rollover energy deals can be implemented if you fail to agree a new deal when your current tariff ends. Your supplier will automatically roll you over to this expensive deal for another year if you don’t switch.

28 day

28 day

Another variable rate contract with typically expensive rates. If your business hasn’t switched energy supplier since the market was deregulated in the 1990s, you may still be on a 28-day contract.

Frequently asked questions about business energy comparison

Switching business energy suppliers usually takes up to six weeks. Once you have requested to switch, your new supplier will inform you of the exact date. You should take a final meter reading once the switch is complete and send it your old supplier so any outstanding credit can be settled.

Your energy will not be cut off at any time during the switch. You also won’t need to schedule an engineer visit, as all your gas and electricity is supplied through the same pipes, no matter your supplier.

Other than switching your energy supply to a cheaper tariff, there are many ways you could keep your business’s gas and electricity usage down in order to get cheaper bills.

More on business energy suppliers

The Big Six energy suppliers – British Gas, EDF Energy, E.ON, Npower, Scottish Power and SSE – are well known in the UK, and still hold a collective majority market share. They are typically seen as a safe option when comparing business energy deals, but it’s likely you could find cheaper tariffs elsewhere. Smaller suppliers also tend to have better customer service as they have more time to focus on individual customer needs, although this isn’t always the case so do your research.

Since the energy market was deregulated over two decades ago, dozens of small, independent energy suppliers have entered the UK market. If you’re looking for an energy supplier that can cater specifically for your businesses’ needs, you may have better luck looking at these smaller energy suppliers. However, make sure your supplier is reliable, as you want any issues with your energy supply to be resolved quickly and efficiently.

If your company prides itself on being eco-friendly, or your just want to do your bit to help the environment, you should choose a green energy supplier when comparing business energy deals. These tariffs offer energy sourced from 100% renewable sources, such as solar or wind power.
