Compare energy deals to find the best gas prices

Run an energy comparison using Utility Saving Expert’s free, impartial, Ofgem regulated comparison tool to find the best deal for you.

When comparing gas deals, reference your annual gas statement so you can input precise data. This helps you create a detailed picture to accurately judge whether you are on the best plan for your energy usage or whether there’s a better tariff available.

Review this every year to check whether you’re on the best gas plan.

Understanding your gas usage in kWh

Gas statements will include important household data like your gas consumption, displayed in a measure of energy called kilowatt hour (kWh).

You are billed in kWh by your utility company because this measures how much energy your appliances use, and for how long. A kilowatt (kW) is the power required for an appliance to work, and a kilowatt hour (kWh) is the energy used each hour that appliance is operating.

Even with kWh as the global measurement for energy, there is no single, consistent price for gas. It varies depending on who you are buying it from and what is written in your contract, so the cost of each kWh could be different for each gas supplier or energy tariff. According to National Statistics, the average cost of gas is 4.17p per kWh.

Most contracts will also include a daily standing charge, which remains the same no matter how much gas you use. The average price of standing charges is £84.62 per year.

How to compare gas providers set prices

Energy companies decide what to charge for gas based on a range of factors including regulations and energy price caps, global production and supply chain costs. Price changes can even be caused by the weather.

Gas suppliers often purchase gas well in advance, sometimes even years ahead of time. This strategic move helps protect the energy companies from gas price rises. Just like suppliers protect themselves from prices hikes, you can too. Choose a fixed-rate tariff to know exactly what you’ll be paying for gas for an agreed period of time, regardless of whether the global price of gas changes.

Customers also have the power to influence the price of energy. Suppliers must price energy competitively in order to keep customers happy long term, or risk losing them to cheaper alternatives. The best thing you can do as a customer is to shop around.


Switching tip: Look up gas deals regularly to check you are purchasing energy at fair rates. Comparing and switching supplier keeps the gas market competitive and ensures you make the most of your money.

Your personal energy projections

If you choose a fixed rate tariff, you can agree the price you will pay for each unit of gas for the duration of your contract. This protects you from unexpected price rises, but your bill could still vary depending on how much energy you use.

For an indication of what you’ll be charged, your supplier will prepare a personal projection for you. This is a type of financial forecasting that is calculated using your history of energy usage and the price you pay for gas. It’s an estimate based on your data.


Switching tip: You can use this same data to enter your annual consumption in kWh when comparing energy deals with Utility Saving Expert. With this information, we can tell you exactly how much you can save by switching.

What to do if you don’t have your annual energy statement

Inputting your annual energy consumption when comparing gas deals ensures accurate quotes tailored to your household needs are generated in the comparison results.

If you don’t have a physical copy of your bill, check to see if you have access to your energy usage in emails from your provider, or using their website or app.

Even if you can’t access your gas bill, it’s still possible to find quotes. As long as you have knowledge of how much you’re spending and can answer some questions about your household and energy usage, you’ll be able to compare energy deals to find a cheaper gas supplier.

Another way to review whether you are overpaying on your utility bills is by familiarising yourself with the types of tariffs and plans that are available. With a better understanding of the deals on offer, you’ll get an idea of where your current tariff and supplier sit in relation to competitors.


How to compare gas prices and suppliers online

Every home will have different requirements, so it’s no surprise that the best supplier will not be the same for everyone. However, some tips for achieving cheaper bills apply to most households. Here are our suggestions for how you can find the best gas tariff:


1. Avoid standard variable energy tariffs

These are default tariffs that are typically very expensive. You might be automatically shifted to this type of tariff after a fixed rate contract ends, so it’s important you always compare your options when your contract end date is approaching.


2. Input accurate details of how you use energy

If you compare energy tariffs using information that is inaccurate, you might not end up finding the optimal deal for you. It’s best to be completely transparent about your energy usage and reference correct data from your gas bills and annual statement.


3. Look out for cheap dual fuel deals

Energy suppliers may offer you a discount for choosing to purchase both gas and electricity from them. Dual fuel options reduce the administrative costs for the company supplying the energy and they will often reward customers with better deals.


4. Compare gas suppliers and don’t be afraid to shop around

Regularly compare gas tariffs to find out whether there’s a cheaper deal. You might even find that your current supplier has a more cost-effective option that you could switch to. Don’t put off comparing gas prices because you think it will be time consuming or confusing, that’s a common misconception. It’s quick, easy and could save you hundreds of pounds.


5. Switch suppliers and gas tariff regularly

Don’t just compare, switch! When you find a better gas tariff, all you need to do is confirm you want to switch. The suppliers will handle all of the processes for you. There’s no need to worry about being left without gas, your supply won’t be interrupted.
