Compare UK Gas Prices and Reduce Your Heating Bills
For most UK households, gas is the primary source of heating and hot water. It’s also one of the biggest contributors to the annual energy bill, and during the colder months, those costs can feel particularly steep.
What many people don’t realise is that a significant number of households are paying more for their gas than they need to. Not because cheaper deals don’t exist, but because switching supplier sounds more complicated than it actually is. Many families stay with the same provider year after year, on tariffs that quietly become less competitive over time.
Comparing gas prices takes a few minutes and can make a real difference. Households that move from an expensive standard tariff to a more competitive deal can save anywhere from £150 to over £600 a year, depending on the size of their property and how much gas they use for heating.
Whether you’re currently with British Gas, Octopus Energy, EDF Energy, E.ON Next, or any other supplier, there may be a better deal available right now. Free Energy Savings lets you compare gas tariffs from trusted UK suppliers quickly and without any obligation.

How Gas Price Comparison Works
The process is more straightforward than most people expect. You provide a few basic details, and the comparison tool searches available gas tariffs across multiple suppliers on your behalf.
To run an accurate comparison, it helps to have the following ready:
- Your postcode
- The name of your current gas supplier
- A recent gas bill, if you have one available
If you don’t have exact usage figures, that’s fine. Most comparison tools can apply standard consumption estimates based on property type and size. You can always update the figures later if you want a more precise result.
Once your details are entered, you’ll see a list of available tariffs ranked by annual cost. You can compare unit rates and standing charges side by side, look at fixed versus variable options, and review any exit fees before making a decision.
If you find a tariff worth switching to, your new supplier handles the rest. They contact your existing supplier and manage the transition on your behalf.
One important point worth knowing: switching gas supplier does not affect your gas supply. Gas still arrives at your home through exactly the same pipes and network. The only change is which company sends you a bill. Switching typically completes within around five days under Ofgem rules.
Why Comparing Gas Prices Matters
Gas is typically used for central heating, hot water, and in many homes, cooking as well. Because of this, it tends to account for the largest share of a household’s energy costs, particularly during autumn and winter when the heating is running regularly.
When a fixed gas tariff ends, many suppliers move customers onto their standard variable rate automatically. It’s a default setting, not necessarily a good deal. Standard variable tariffs are almost always more expensive than the competitive fixed deals available on the open market, and customers on them often don’t realise it until they check.
Gas prices are also influenced by factors outside any individual supplier’s control, including wholesale gas costs, global market conditions, and government price cap decisions. These factors shift over time, which means the tariff that offered reasonable value eighteen months ago might no longer be competitive today.
Comparing gas tariffs regularly means you’re not quietly overpaying for your heating. Even a saving of £30 a month adds up to £360 over a year, which is a meaningful reduction in household costs for most families.
The key reasons households benefit from comparing gas prices include:
- Reducing monthly heating bills by leaving an expensive standard tariff
- Locking in a fixed rate to protect against price rises
- Finding a supplier with better payment plan options
- Accessing green gas tariffs if reducing carbon emissions matters to you
It’s also worth noting that energy suppliers typically offer their most competitive rates to new customers. Comparing puts you in exactly that position.
Types of Gas Tariffs Explained
Before you compare deals, it’s worth understanding what you’re looking at. Gas tariffs come in a few different forms, and each works differently.
Fixed Gas Tariffs
With a fixed tariff, your unit rate and standing charge are set for a defined period. Most fixed deals run for 12 or 24 months, though some suppliers offer shorter or longer terms.
The main advantage is predictability. If wholesale gas prices rise during the winter, your rate stays the same. For households that want to budget accurately for their heating costs, a fixed tariff offers real peace of mind.
Some fixed tariffs include exit fees if you leave before the contract end date. Others don’t. It’s worth checking this before you commit, particularly if you think your circumstances might change.
Variable Gas Tariffs
Variable tariffs move in line with market conditions and are subject to the Ofgem price cap. When gas prices fall, your bills can reduce. When they rise, your costs go up.
These suit households who want flexibility, particularly those who aren’t ready to lock into a fixed deal or who expect prices to drop in the near term. Standard variable tariffs are also the type most people end up on by default when a fixed deal expires.
Green Gas Tariffs
Some suppliers offer tariffs that offset the carbon emissions associated with your gas usage, typically by investing in renewable energy projects or carbon offsetting schemes. These are appealing for households who want to reduce their environmental impact without switching entirely to electric heating.
Green gas tariffs are sometimes slightly higher in price, though the difference varies considerably between suppliers. It’s straightforward to compare green and standard options side by side when you run a comparison.
The Best Gas Suppliers in the UK
There’s no single answer to which gas supplier is best, because it depends on your property, your usage levels, and what you prioritise as a customer. That said, some of the most widely used suppliers in the UK are worth knowing about.
British Gas is the UK’s largest energy supplier, with a broad range of gas tariffs and additional services including boiler cover and home care plans. It’s a familiar name for a reason, though not always the cheapest option.
Octopus Energy has built a strong reputation for customer service and transparency, offering a range of tariffs including options for households interested in greener energy.
EDF Energy is one of the larger players in the UK market, offering both fixed and variable gas tariffs alongside a focus on lower-carbon energy.
Scottish Power is one of the longer-established suppliers, offering standard and green tariffs to customers across the country and consistently competitive pricing on fixed deals.
OVO Energy places sustainability at the heart of its offering, with carbon offsetting built into some plans and a straightforward approach to billing.
Different households weigh these things differently. Some want the lowest unit rate available. Others care more about customer service, smart meter support, or green credentials. Comparing several suppliers before making a decision gives you a much clearer picture of what’s actually out there.

How Much Could You Save by Switching Gas Supplier?
Savings depend on your property, how much gas you use for heating, and the tariff you’re currently on. Homes with older boilers or poor insulation tend to use more gas, which also means more potential to save.
As a rough guide:
- Flats: potential savings of £150 to £250 per year
- Terraced homes: potential savings of £200 to £350 per year
- Semi-detached homes: potential savings of £300 to £450 per year
- Detached homes: potential savings of £400 to £600 or more per year
These estimates assume you’re currently on a standard variable tariff and switching to one of the more competitive fixed deals available at the time of comparison. Actual savings will vary.
The households that tend to benefit most are those who haven’t reviewed their tariff in two or more years. Heating costs are high enough that even a modest reduction in unit rate can produce a meaningful saving over twelve months, particularly through winter.
A typical semi-detached home in Leeds, for example, could save around £350 a year simply by moving off a standard tariff onto a competitive fixed deal. That’s without changing anything about how the household uses energy.

How to Switch Gas Supplier: Step-by-Step
Switching gas supplier is simple. Here’s what the process looks like from start to finish.
Step 1 – Compare gas prices Enter your postcode, current supplier, and usage details. Estimated figures work fine if you don’t have exact numbers. You’ll see a list of available tariffs ranked by annual cost.
Step 2 – Choose a tariff Review your options. Look at unit rates, standing charges, contract length, and whether there are exit fees. Choose the deal that makes sense for your household.
Step 3 – Enter your details You’ll need your name, address, and current account information. The whole process is handled online and typically takes just a few minutes.
Step 4 – Your new supplier takes over Once you’ve confirmed the switch, your new supplier contacts your existing one and manages the changeover. You don’t need to do anything further.
Step 5 – Switch completed Most switches complete within five working days. You’ll receive a final bill from your old supplier, and your new tariff begins from the agreed start date.
No engineer visit is needed. Nothing changes at your meter or pipework. Your gas supply continues without any interruption throughout the process.
What Information Do You Need to Compare Gas Prices?
You don’t need much to get started. The basics are:
- Your postcode
- Your current gas supplier
- Whether you have a single fuel (gas only) or dual fuel account
If you have a recent gas bill available, you can also enter your current unit rate and standing charge. This makes the comparison more precise, since you’ll be able to see exactly how a new tariff compares to what you’re currently paying for heating.
If you don’t have that detail to hand, don’t worry. Comparison tools use average consumption estimates based on property type and size. These won’t be exact, but they’re reliable enough to tell you whether a meaningfully cheaper deal exists.
For heating-heavy households, it’s worth trying to enter actual usage figures if you can find them. The higher your gas usage, the bigger the difference a lower unit rate can make.

Frequently Asked Questions
Under Ofgem rules, most gas switches complete within five working days. Once you’ve confirmed your new tariff, your new supplier contacts your existing one and manages the process. You’ll receive a final bill from your old supplier, and the new tariff begins from the agreed start date. You don’t need to chase anything or make any calls.
No. Your gas supply continues without interruption throughout the switching process. Gas arrives through the national grid and your local distribution network, and none of that changes when you switch supplier. Your heating and hot water will work exactly as normal from start to finish.
Yes, in most cases. Smart meters installed under the SMETS2 standard, which covers the majority of meters fitted in the last few years, continue to work in full smart mode after a switch. Some older SMETS1 meters may temporarily revert to basic mode while the new supplier connects them to their system, though this is usually resolved within a few weeks. If smart functionality is important to you, it’s worth confirming with the new supplier before you switch, but it’s rarely a good reason to stay on an expensive tariff.
It depends on your current tariff. Standard variable tariffs generally have no exit fees, so you can leave at any time. Fixed tariffs sometimes include exit fees if you leave before the contract end date. These are listed in the tariff terms, and a good comparison tool will flag them clearly. If you’re within 49 days of your contract ending, most suppliers allow you to switch without charging a fee, so timing your comparison around that window is worth considering.
Once a year is a reasonable starting point. The best time to compare is around 49 days before your current fixed deal ends, since that’s typically when you can switch without incurring exit fees. If you’re already on a standard variable tariff, there’s no fixed contract to consider, so you can compare and switch at any time. It’s also worth checking when there’s a significant move in wholesale gas prices, as that often shifts the deals available.
There’s no fixed answer, because tariff pricing changes regularly and the cheapest option depends on your location, usage, and the deals available when you compare. A supplier offering the best rate today may not be the most competitive in three months. The most reliable way to find the cheapest gas tariff for your household is to run a comparison using your own details.
In most cases, yes. If the gas account is in your name and you pay the supplier directly, you’re entitled to switch. It’s worth checking your tenancy agreement first, as some contracts mention energy suppliers, though such clauses aren’t always enforceable. If your landlord pays the gas bill and recharges you, the situation is more complicated, and you’d need to discuss it with them before making any changes.
Your direct debit to your old supplier will stop once the switch is complete and your final bill has been settled. If you’re in credit at the time of switching, your old supplier is required to refund that balance. Your new supplier will set up a new direct debit based on your estimated annual gas usage and the tariff you’ve chosen. It’s a good idea to review the amount after the first month or two to make sure it reflects your actual heating usage.
Yes. Prepayment meter customers can switch gas supplier. The process is broadly the same as for credit meter customers, and your new supplier will send a replacement top-up key or card once the switch is complete. Some suppliers also offer to replace a prepayment meter with a standard credit meter at the time of switching, depending on your eligibility. It’s worth asking about this when you compare, particularly if a standard meter would be more convenient for your household.
Your old supplier is notified by your new supplier as part of the switching process. You don’t need to call them or give notice yourself. They’ll issue a final bill based on your closing meter reading, and if you’re in credit, they’re required to refund the balance. The whole handover is managed between the two suppliers, so there’s nothing you need to coordinate directly.
