Compare gas-only tariffs

You’ve got two options for switching timeframes. We suggest you choose the one that best suits you…

Option 1) You can fast track your switch. In which case, you should be up and running with your new supplier in just five working days. You can cancel at any time up to 14 days after clicking ‘confirm’ on our site, under the terms of your cooling-off period. 

Option 2) Alternatively, you can choose a standard switch. That means your switch will only go through after your 14-day cooling-off period and should be completed in around 15 days. 

The aim of the Energy Switch Guarantee is to give consumers more confidence in switching energy suppliers, as well as making the overall process quick and easy. When you change to a new energy deal, the whole switchover of service is taken care of by your new provider, and you won’t be without gas or electricity at any point – and in the unlikely scenario that any problems do occur, your new provider will work to resolve it as soon as they can.

You’ll also be able to cancel the switch at any time within 14 days – if you do, you’ll remain with your old provider. If you have any credit from your previous energy account, this will be refunded within 14 days of your final bill.

If you’re a tenant and you pay the supplier directly, you’ll be able to switch supplier. If your landlord pays the bill out of your rent, you won’t be able to switch without discussing it with them first, and they’ll need to make the switch themselves.

Most of the country’s energy comes from the Big Six, the six biggest energy suppliers in the UK – these are:

• British Gas

• EDF Energy

• E.ON

• Npower

• Scottish Power

• OVO

However there’ve been an increasing number of smaller providers, such as First Utility, Octopus Energy, and Ecotricity. They may not be as well-known as the ‘Big Six’ companies, but they do offer certain advantages:

• Some smaller suppliers specialise in green energy

• Many also come out on top for customer service, compared to the Big Six

You’ll be able to switch from a prepayment meter to a credit meter if you aren’t in debt to your current provider – but you might need to undergo a credit check. Some suppliers might charge a fee to change your meter, but not all will.

Shopping around and comparing deals is the best way to find a better deal.

Between 1 October and 31 December 2025 the energy price cap is set at £1,755 per year for a typical household who are on dual fuel standard-variable tariffs and who pay by direct debit.

If you’re on a fixed-rate tariff it’s likely you’ll need to pay an exit fee when you switch, as most fixed tariffs require you to sign a contract.

On the other hand, you don’t need to sign a contract for standard variable tariffs – as a result, you won't have to pay any exit fees if you switch.

Finding an energy tariff for your business is slightly different from domestic energy. Energy suppliers for businesses will offer the option of auto-renewing your contract, and while this might reduce the hassle of finding a supplier, you may also be on a more expensive tariff than you need to be.

All you need to do is give us at MoneySuperMarket a few details about your business’s energy usage and location, and we'll do our best to find a better deal for your business. You can request a call back from our energy experts, or call them yourself on 0800 088 6986, and discuss your requirements so you can find the right business energy deal for you.

Although gas prices fell during 2023 and 2024, they're still well above their pre-energy crisis levels.

What's more, it's thought unlikely that energy prices will return to pre-pandemic levels before the end of the decade.

Whether gas prices go up or down in the short term will depend on several factors, such as:

• Weather and time of year – recent winters in the UK and Europe have been milder than normal, resulting in lower demand

• A concomitant reduction in usage from households, in response to the warmer weather

• European countries stockpiling supplies, so they're less reliant on Russian gas

It really depends on the tariffs and the suppliers you’re comparing. 

Some are able to offer gas more cheaply on its own, which you can combine with a cheap electricity tariff from another supplier. Conversely, others, meanwhile, give you the best value with a dual fuel service. 

The best way to find out is to compare your options across the board, which we’ll help you do with our comparison tool. 

There are other benefits to choosing a dual fuel service besides cost, of course. For instance, it reduces your household admin and streamlines your finances, as there’s only one bill to deal with. You may find dual fuel simply makes life easier.  

It’s a little confusing, but the short answer is yes. 

Nearly all energy suppliers, including the Big Six, have green tariffs available. The energy you consume on these plans does come from the National Grid, and is therefore all the same – but by choosing a green energy tariff, it means that the energy the supplier purchases to go back into the grid will be green. 

This applies to electricity from most suppliers, but for green gas you may need to look to a smaller supplier that focuses on green initiatives. 

And if you’re wondering how gas can be considered green, we can answer that too! These suppliers help the environment by offsetting the gas they provide, through major carbon reduction projects.  

In normal circumstances, as long as you’re switching gas supplier regularly – every year or two – you should generally be getting a good deal, regardless of when you switch.

If you’re flexible on when you switch, however, the best time to do so is in the autumn before the winter hits. This way, you can make sure you’re not overpaying in the cold months when you’re most likely using more gas to heat your home.

However, due to market conditions in the recent years, switching deals might not always necessarily save you money.

Look out for bills coming through your door from a gas supplier. 

Or, talk to the Meter Point Administration Service who can find out for you. You can use the Find My Supplier tool on their website, or call them on 0870 608 1524. 

This depends on a few factors. But it’s mostly driven by wholesale prices – the costs that energy suppliers are paying for the gas in the first place.

These in turn are driven by factors such as supply chain costs, global production levels, how far in advance the supplier purchased the gas, and so on. Some tariffs are also guided by the price cap, set by Ofgem.
