What does gas-only mean?

In the context of energy deals, "gas-only" means that you're only comparing your gas service - not your electricity service or a combination of your gas and electricity service (normally called a dual fuel energy deal). Some homes get their electricity and gas from two different suppliers, which can sometimes work out cheaper. If you want to do this, you'll need to make sure you only compare gas-only deals when you're looking to switch.

Most energy suppliers offer gas-only deals. Enter your postcode above to see the gas tariffs that are currently available.

How to find and compare the cheapest gas suppliers

How to compare gas prices

The price of your gas bill can depend on your usage, your area and the type of tariff you’re on – and it’s likely you could cut your heating bills by shopping around for a cheaper deal. The only way to find out which supplier has the best deal for you is to compare gas prices on a site like Uswitch.

  • Run energy comparisons regularly, we recommend at least once a year to ensure you’re on the best deal available at the time

  • To run the most accurate gas comparison, try to get an annual statement from your current supplier

  • Enter your annual energy consumption in kWh so we can tell you exactly how much you can save by switching. If you don’t have an annual statement, we can still give you an accurate quote based on how much you’re spending now.

When you compare gas plans with Uswitch we'll show you different types of plans so you can look beyond only gas prices. If you’re looking for peace of mind, for instance, then a fixed plan, which guarantees your rates at a certain price for a certain period of time, might be a good option.

Gas prices per kWh explained

When you compare gas prices with Uswitch, you’ll see your projected annual spend. This is how much we think you’ll spend over the next 12 months based on your usage and the price the supplier is charging per unit of gas – which is measured in kilowatt hours or kWh.

When you see different gas prices from different suppliers that’s because each supplier and tariff charges a different rate per kWh. Your gas bill will also include a standing charge, which is charged per day regardless of how much gas you use.

What is the average cost of gas per kWh?

The cost of gas per kWh will depend on how much the supplier is charging for your particular gas tariff. If you're on a fixed tariff, your gas unit rates will be fixed for the duration of your contract.

However, with the vast majority of UK households on standard variable tariffs, their unit rates are capped under the energy price cap. The price cap level changes every three months but, under the current level which is valid until 31 March 2024, the average price for gas is 7.42p per kWh.

How do gas providers set prices?

Gas prices depend on a wide array of factors. These range from global production levels and changing supply chain costs to unexpected weather conditions, such as a particularly long winter. Each of these elements and many more can affect individual gas companies in different ways. In addition, gas suppliers often purchase gas months or even years in advance to mitigate potential gas price rises.

For consumers, the simplest way to ensure fair rates from a gas supplier is to frequently compare gas prices from different suppliers. The only thing that keeps the gas market competitive is the prospect of customers switching gas suppliers.

Tips for getting the cheapest gas tariff for your home

  • Make sure you’re not on your supplier’s standard variable tariff – this is the default tariff you’ll be placed on if you haven’t switched for a while and is typically the most expensive type of plan

  • When you compare gas plans, try to give accurate usage details. You can find these on your gas bill or annual statement

  • If you’re on a gas-only plan but also use electricity, consider switching to a dual fuel tariff as they can be more cost effective

  • Switch gas regularly. You might not even need to change your gas supplier to save money – compare gas prices from your current supplier to see if they have a better deal.

The best way to ensure you’re not overpaying for your gas is to compare gas prices with a trusted energy price comparison site like Uswitch.

Will switching to a new gas supply affect my current supply?

No. Should you choose to switch you won’t have to endure a gas outage so don’t let this put you off your search for the cheapest gas suppliers.

When you switch your gas supplier the actual gas that is piped to your home remains the same. The only difference is how that gas is paid for, and how it’s charged.

Switching gas supply is simply a case of changing who is billing you and the rate they charge per kWh of gas used. It’s as simple as that.

In addition, gas providers sometimes offer exclusive plans and deals through Uswitch, which you can find whenever you compare the cheapest gas prices.

When is the best time of year to switch energy supplier?

To make sure you’re on the cheapest gas deal, you should make a habit of switching every 12-18 months whenever your fixed energy plan is coming to an end. If you don’t switch before your fixed plan ends you’ll be rolled onto your supplier’s standard variable or default tariff, which are typically the most expensive type of plan.

In terms of the calendar year, it’s best to compare gas deals and switch around autumn, before the winter months. This can help you ensure you’re not overpaying in winter when your gas and electricity usage is likely to be higher.
