Did you know that only 11 energy price comparison sites in the UK are Ofgem-accredited for electricity & gas tariff switches? Learn more about each site here including how much they promise you can save on your energy bills and which one is best.
Please note the sites listed below are ranked based on estimated traffic levels from Ahrefs with the most popular websites listed first. Data for accredited sites comes from Ofgem. Finally we currently have affiliate relationships with Energyhelpline, USwitch and Energylinx.
1. USwitch
Claimed Savings*: Up To £479
Founded: 1998
Estimated Visitors To Site Per Month: 220,000 per month (energy only)
Power Compare Rating: 9.1 out of 10
Summary: USwitch is a free, independent price comparison service that helps consumers compare gas and electricity prices and switch energy suppliers to save money.
Since 2006 USwitch has been fully accredited by the Ofgem Confidence Code. With many energy comparison sites to choose from, USwitch has been one of the longest standing signatories to the Ofgem code, and a primary contributor to achieving gas and electricity pricing transparency.
USwitch makes money based on commercial agreements with some energy suppliers. They charge suppliers a fee when they switch customers to them, which means they can provide consumers with a free service. Their commercial relationships help make the switching process as simple as possible for customers and in some cases allow them to negotiate exclusive deals that are not available directly from the supplier.
USwitch tries to include as many suppliers and products on the market in their comparisons as possible. However there are circumstances where a supplier or a product cannot be included in their search – for example, they may not be able to show a supplier’s products because they do not have an agreement with them or because they do not wish to be included in a comparison.
The data they use to calculate your results for their energy switching services is provided directly by suppliers. They monitor all suppliers continually and update their site regularly to ensure their results are comprehensive and accurate.

Here are a few common questions and answers about energy switching & comparison sites:
Which is the best energy price comparison site?
The simple answer is that there is no single best energy price comparison site. USwitch is by far the most popular and has an aggregate review score of 9.1 out of 10 and promises savings of up to £477.
Only Simply Switch (9.3 out of 10) & Energylinx (9.2 out of 10) have higher aggregate review scores. And only the Energy Helpline claims it can save you more (up to £537), although the claim is made with older data.
If you want to get the absolute best deal, you’re best bet is to try out a few comparison sites since they’re all free to use. Just make sure you look at price per kWh and standing charges when comparing tariffs, since claimed savings may differ from site to site.
How do energy comparison sites make money?
They usually work on a commission basis with those companies they have a deal with. However they are obliged to offer the whole of the market to their customers. So this means that you should see every available tariff – not just those ones that the comparison site makes money from.
You are free to choose whichever one suits your needs.
Do energy switching sites show all tariffs & deals?
In theory, all of the sites above should show all tariffs. However, the data they use to make their calculations generally comes from energy suppliers themselves, so will only be as good as the data provided.
Moreover, comparison sites can only help you actually make the switch if they have a commercial agreement with the supplier (see above).
This may mean that some comparison sites highlight certain suppliers since they can offer a full switching service but there should be a way to filter to show all results.
Is Power Compare Accredited By Ofgem?
No, we are an energy information website and not a full comparison site, supplier or broker. Therefore, we work with USwitch and Energy Helpline to provide comparisons for homes and Love Energy Savings for comparisons related to businesses.
What is an ‘Ofgem Confidence Code’ energy price comparison site?
The Confidence Code is a code of practice to govern independent energy price comparison sites. We accredit sites to the Code.
The Code insists that the sites we accredit follow key principles for how they must operate their service. Using a site with the Confidence Code logo means that the process of switching energy supplier should be easier, more reliable and reassuring for you.
We regularly review the code to make sure it provides the right protections for consumers. You can find further information on the rules Ofgem-accredited sites must stick to in the Confidence Code code of practice.
Why choose an energy price comparison site covered by the Ofgem Confidence Code?
Again Ofgem states that:
The sites covered by the Confidence Code act independently of suppliers, so you can be sure that when you are presented with options and prices, they have been calculated and are displayed in a fair and unbiased way.
Comparison sites bearing the Confidence Code logo:
- help you find the best deal for you in your local area
- provide a free and easy-to-use switching service
- give detailed information on each tariff, including gas and electricity unit prices
- detail any discounts available.
What can I do if I have a complaint about an Ofgem-accredited energy price comparison website?
If you have a complaint about one of the 11 sites above, Ofgem recommends you first try and resolve it with them directly.
If it is not resolved after that you can then contact Ofgem directly so that they can raise the issue with the comparison site. You can do so by:
