How do I compare gas prices?

Comparing gas prices with MoneySuperMarket is quick and easy. All we need is a few details about yourself, your home and your approximate energy usage. The more accurate you can be, the more accurate your quote will be.

Once that's done, we’ll show you a list of quotes from the UK’s leading energy providers, including the Big Six as well as smaller companies. You’ll be able to compare tariffs by the rate you’ll be on, an estimate of your monthly and yearly costs, and anything else you can expect. 

When you’ve found the deal you want, just click through to the provider to finalise your purchase. If you chose to fast track your switch, you should be switched to your new tariff within five working days with no hassle thanks to the energy switch guarantee.

What information do I need to compare gas suppliers?

You’ll need: 

  • Your address

  • Whether you want just gas, or electricity as well

  • Your current supplier 

  • Any information you can provide on your current bills – such as you current tariff, and how you prefer to pay

  • The current state of your energy usage, such as how much gas you use – we can show you tariffs without this information, but the more you can provide us, the more accurate your quotes will be

What types of gas tariff can I get?

When you compare gas tariffs you’ll see several different types available, including:

  • 1


    fixed-rate tariff means the cost-per-unit of gas will stay the same for the duration of your contract. This doesn’t necessarily mean your bills will be the same each month – the amount you pay will depend on the actual amount of gas you use. The main benefit of fixed-rate gas tariffs is that you’ll be protected against price rises – but equally you won’t be able to take advantage if prices drop

  • 2


    Sometimes known as standard variable tariffs, these are generally the most common option – they’re also what you’ll be moved over to if your existing fixed-rate tariff ends

  • 3


    Prepaid gas tariffs let you pay in advance for gas – you top up your prepayment meter using a card, key, token or your supplier’s online facility (if they have one). If you’re on a prepayment tariff you might find gas is more expensive per unit, however they can be a good way to manage your gas usage if you’re on a budget

What is a dual fuel tariff?

dual fuel tariff gives you both gas and electricity from the same provider, which can be more convenient as you’ll only have one point of contact for both suppliers. Additionally if you’re using a smart meter, you’ll only need the one for both gas and electricity if you’re on a dual fuel tariff. You can take out both fixed and variable dual fuel tariffs.

Are dual fuel energy tariffs cheaper?

Dual fuel tariffs can be a cheaper option as some providers offer discounts if you get both gas and electricity with them. However this won’t always be the case, so it’s best to compare all your options so you can find the best price for what you need.

How do gas providers set prices?

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.

How can I reduce my gas bill?

As you're probably aware, unprecedented market conditions mean low cost deals are hard to come by and many of us are facing hefty energy bill increases. 

Until the market returns to something approaching normality, though, you can also make a few changes here and there to improve the overall efficiency of your home’s gas usage:

  • Prevent heat loss: A significant portion of energy used by UK homes goes towards space heating, understandable for this cold and rainy island we inhabit. Installing insulation, draft excluders and double-glazing help keep the heat where it should be

  • Replace your equipment: Newer boiler models are generally much more efficient at heating your home, though it can be expensive to replace an old boiler – it’s worth working out the costs to see if you could save. You might also consider a smart meter and smart thermostat if you’re eligible, as these let you keep a closer eye on your energy consumption so you can see where you need to change your habits 

  • Take advantage of government schemes: Certain government schemes, including the winter fuel payment and the affordable warmth obligation, give eligible people help with their energy bills and the overall energy efficiency of their homes

Find everything you need to know about energy 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. 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

  • SSE

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, however 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.

The energy price cap is calculated and set by Ofgem, and is usually reviewed quarterly. The cap currently stands at £1,971 for customers on standard variable tariffs (SVTs) and £2,017 for customers on pre-payment tariffs. 

Amid ongoing supply constraints in the energy market and the war in Ukraine, this was due to rise to £3,549 from October 2022, putting unprecedented strain on household budgets. 

However in response to the cost-of-living crisis, the government intervened and announced the Energy Price Guarantee scheme in September 2022. 

This temporarily supersedes the price cap and effectively caps prices at £2,500 for the average household from 1st October 2022. 

The Energy Price Guarantee will remain in place for the next two years, until Ist October 2024. 

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. However you won’t need to sign a contract for standard variable tariffs, and there are usually no exit fees.

Finding an energy tariff for your business is slightly different to 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.

At the time of writing (August 2022), gas prices are much, much higher than they have been in recent years. There are a few reasons for this, but it all essentially comes back to the global supply chain. 

Some factors hitting gas supplies include: 

  • The war in Ukraine that has reduced the availability of Russian gas 

  • A cold winter last year in Europe that put pressure on supplies

  • A relatively windless summer in 2021, which made it difficult to replenish gas supplies 

  • Increased demand for resources as countries recovered from Covid-19 lockdowns

  • Increased demand for natural gas from elsewhere in the world, in particular China

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 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.  

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.  

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.
