What's in This Guide to Business Gas?

Business Gas Prices

Lots of different costs make up your business gas bill, and it can be difficult to grasp what they all mean and why you are charged them. When comparing business gas prices, however, there are only 2 costs that you should pay close attention to: the unit cost and the standing charge.

But what are these?

  • The unit cost refers to the price you pay for each unit of gas (measured in kWh) that your business uses
  • The standing charge is a fixed daily amount that you pay to your energy supplier for delivering gas to your business. It is charged regardless of whether you use gas on a given day

By choosing an energy supplier that offers low unit costs and standing charges, you’ll be well on your way to making significant savings on your business’ gas bills.

The table below shows you business gas prices from some of the most popular energy supplies in the UK.

Gas Supplier

Unit Cost (p/kWh)

Standing Charge (p/day)

British Gas
Corona Energy
EDF Energy
Gazprom Energy
Hudson Energy
Opus Energy
Scottish Power

*Costs are based on deemed rates and so are likely to be the highest prices you’ll be quoted. Deemed rates are charged to businesses who have no formal contract with an energy supplier.

Some energy suppliers have now started to offer gas tariffs without a standing charge. This means that you are only paying for the gas you use. So if your business doesn’t use gas for long periods of time, you won’t be charged a penny from your energy supplier.

While this can seem like an attractive option, these tariffs tend to have a much higher unit cost. So while you’re saving on daily charges, the more expensive unit costs can mean that you’ll actually end up paying more for your gas, particularly if your business has medium-to-high consumption.

But How Much Should Your Annual Gas Bill Be?

We’ve put together the table below to to give you an idea of how much you should be paying based on the amount of gas your company uses.

Business Size

Annual Gas Usage (kWh)

Annual Gas Bill

5,000 to 10,000
£241 to £391
15,000 to 25,000
£541 to £841
30,000 to 50,000
£991 to £1,591

*Calculations based on a unit cost of 3p and a standing charge of 25p.

What Affects Business Gas Prices?

  • Gas consumption. The more gas you use, the more your bill will be. Nevertheless, the unit cost you’ll be charged will generally fall as your business gas usage increases
  • The type of tariff you opt for. Gas prices can vary wildly depending on whether you choose a fixed or flexible tariff. You often get cheaper prices if you sign up to a fixed tariff. See below for more information
  • Gas flow availability. When there is more gas available than meets demand, prices will fall. Yet when demand for gas outstrips its supply, gas prices will start to creep up. Supply tends to outweigh demand in the summer, when businesses are using less gas for heating, for example
  • Business location. Sometimes referred to as the “postcode lottery”, gas prices vary depending on where in the UK your business is located. This is for several reasons, including how much gas a supplier distributes in your area. Prices in the south of England tend to be the cheapest. For example, energy supplier Bulb currently charges businesses in South East England 3.3p per day for gas, while businesses in the North East England are only charged 3.15p

Business Gas Tariffs

A tariff is the pricing structure an energy supplier charges you for using gas. Each one is different, so it's important to take a look at all of them and choose one that best suits your company’s needs.

For UK businesses, there are 4 main types of gas tariffs available:

  • Fixed tariffs
  • Flexible tariffs
  • Green tariffs
  • Dual fuel tariffs

Fixed Tariffs

A fixed tariff offers you a guaranteed unit cost, usually until a defined end date. This simply means that the cost per kWh of gas that your business uses will stay the same for the duration of your contract, regardless of changes in the market price. Fixed tariffs are usually available over 1 and 5 years.


  • Often the cheapest type of tariff
  • Provides you with protection from price hikes in the cost of gas
  • You know exactly what you are paying for (so no nasty surprises)

X Cons:

  • You’re locked into a contract and will have to pay exit fees if you decide to leave it early
  • You’ll miss out on cheaper gas prices if market prices suddenly fall

Flexible Tariffs

Also known as a ‘standard’ or ‘variable' tariff, a flexible tariff offers you variable prices for your gas. This means that the unit cost of gas changes depending on fluctuations in the market price. So on Friday your business could be paying just 3.4p per kWh of gas, while on Monday your business could be paying a huge 6.2p per kWh of gas. Unlike fixed tariffs, flexible tariffs often don’t have a contract end date.


  • Your business can secure better rates than with a fixed tariff
  • Allows flexibility since there is no contract end date
  • You won’t be charged any exit fees when you leave

X Cons:

  • You’re at risk of paying high unit prices for your gas if market prices suddenly increase
  • Flexible tariffs are often a more expensive option than fixed tariffs

Green Tariffs

A green tariff supports renewable energy production and can mean one of two things: that some or all of the gas that you buy from your energy supplier is produced by renewable sources such as biomethane. Or, that your energy supplier will make a contribution towards a renewable energy project with the money you used to purchase gas from them. Green tariffs can be fixed or flexible in nature.


  • Boost your company image
  • Take advantage of a more sustainable supply of gas
  • Fixed green energy tariffs are often cheaper than flexible tariffs

X Cons:

  • The green gas market is still in its infancy, so you might struggle to find a tariff that suits your business needs

Dual Fuel Tariffs

A dual fuel tariff is one which combines your gas and electricity supply into one contract. In other words, you get all your business energy from one supplier instead of getting your gas and electricity from different suppliers. Dual fuel tariffs can be fixed, flexible or green.


  • Easier for you to manage your energy account if both your gas and electricity are from the same supplier
  • Some suppliers offer discounts to businesses who choose dual fuel tariffs

X Cons:

  • Most energy suppliers do not offer dual fuel tariffs to businesses, so it might be difficult for you to find one

Which Tariff Is Right for Your Business?

There is no right or wrong answer when it comes to deciding what gas tariff your business should go for – it’s all about determining what is best for your business needs. Some factors that you should consider when making your choice include:

  • How much gas you use and whether this varies wildly from month-to-month
  • How long your business will be in its current premises
  • Whether you want a supply of gas and electricity
  • If you want to power your business using a renewable supply of gas
  • Whether you want to benefit from potential reductions in gas prices in the future

How to Choose a Business Gas Supplier

Don’t just choose the first business gas supplier you find. Always compare like-for-like quotes from as many suppliers as possible. This will ensure that you get the best deal and are not wasting hundreds (or even thousands) of pounds on a service that is not right for your business. When comparing business gas suppliers, there are a number of questions you should ask yourself to help you make your decision:

  • Do they provide the type of tariff you want? Is it a length that suits your business needs?
  • What price have they quoted you? Could you find a cheaper price elsewhere?
  • Do they provide online account management or paperless billing?
  • What are their reviews like? Is their customer support team easy to get hold of?
  • Do they offer any additional services such as smart meter installation or repairs?
