What are gas-only tariffs?

Gas-only tariffs are aimed at customers who aren’t interested in dual-fuel tariffs for whatever reason. You may be happy with your current electricity deal or prefer to perform separate searches for cheap gas and electric prices. Gas-only tariffs cover your gas supply, which is primarily used to run gas appliances and heat your home. 

Gas price comparison considerations

The obvious driver for using a gas comparison site is price – most people are looking for the cheapest gas supplier to save money. But you may have other priorities to consider – for example, you may want a supplier with a good customer service record, or one with strong green credentials. The marketplace is increasingly crowded, with smaller suppliers looking to gain a foothold over the big six energy companies, giving you more choice than ever before.

How to choose the right gas supplier

The quickest and simplest way to find the best gas supplier for your individual needs is through a price comparison website. After entering the relevant information about your current supplier and usage, you can use the site’s filters to show only those plans with all the features you’re looking for. You then click on each deal to get the details you need to make an informed choice about which supplier and plan meets your needs best. From here just select your chosen tariff and step through the guided process to confirm your switch.

Average gas price per kWh

When you compare gas prices using a price comparison website, the results are usually generated from your ‘personal projection’, which estimates your likely bill over the next year based on your energy consumption and current plan.

The first key metric used when calculating gas prices is what your current supplier charges you for each unit of gas you use – measured in kilowatt hours (kWh). The second is the standing charge, which is a fixed amount charged per day regardless of your gas usage. Both are used to calculate your personal projection.

According to the Energy Saving Trust, the average gas price per kWh is 4.17p and the average annual gas standing charge is £93.39 (as of April 2020).

Are gas-only tariffs more expensive than dual fuel tariffs?

There’s no hard and fast rule that says separate electric and gas-only tariffs work out more expensive than dual-fuel tariffs. The relative costs will be determined by your unique circumstances, such as location, property size and insulation, and the number of occupants living in your property. Just make sure to keep a note of your energy usage, supplier and current plan or tariff to provide your gas comparison site with accurate information to find the best plan for you.

How to compare gas-only tariffs and switch to a new supplier 

When you’re ready to perform your gas comparison and potentially switch gas supplier, start with a general energy comparison site, filtering your results to show gas-only plans. Remember to provide accurate information to deliver the best results – in addition to consumption, supplier, and current tariff you may need to include additional information like the type of meter you’re using. 

The savings you’ll see are based on your personal projection, which reveals how much you can expect to pay over the following 12 months if you stick with your current plan. From here you should have a clear picture to help you compare gas plans and see which one best matches your current circumstances, requirements and – of course – budget. Once you confirm your switch, it should be completed within 21 days under the Energy Switch Guarantee (check your new supplier has signed up to it before switching).

How can I get a cheap gas-only deal?

The answer is simple: run a gas comparison on an energy comparison website to see what deals are available in your area, then compare them with your current deal. Use the filters to narrow your options, focusing on targeting the cheapest gas supplier over other considerations. Remember, you may find you’re already on the cheapest deal, which means there’s nothing else you need to do; otherwise, follow the site’s instructions to select your chosen tariff and perform the switch.
