No, that's virtually impossible, but we do the best we can. We currently cover 62 mobile providers, including all the major networks and retailers such as Amazon, Carphone Warehouse and John Lewis.
If we don't include a specific retailer in the tool, it's usually because they're so new/small that we're not sure how they perform in terms of customer service.
By default, we also don't show deals that require you to claim cashback at strict intervals throughout the contract, as most people don't bother or simply forget to claim these. They are referred to as 'multiple redemption' in the tool. Of course, if you do want to jump through these hoops to save even more, you can choose to show these using the filters in the results page.
We're always happy to hear about deals we might have missed, let us know by emailing the details to email@example.com. We'll take a look to see if it's good enough to include.
If a link has an * by it, it is an affiliated link that helps MoneySavingExpert stay free to use, as it is tracked to us. If you go through it, it can sometimes result in a payment or benefit to the site. It's worth noting this means the third party used may be named on any credit agreements.
You shouldn't notice any difference and the link will never negatively impact the product. Plus the editorial line (the things we write) is NEVER impacted by these links. We aim to look at all available products. If it isn't possible to get an affiliate link for the top deal, it is still included in exactly the same way, just with a non-paying link. For more details, read How This Site Is Financed.
The tool relies on providers/retailers telling us about their latest tariffs and products. We'll ask it for this twice a day as prices don't tend to update much throughout the day. During busier periods, such as Black Friday and Christmas, prices can change multiple times a day, so we'll ramp up the amount of times we ask providers for pricing information.
Our small editorial team will try to ensure we display deals as soon as they come to market, including deals we've blagged as and when they become available.
We don't factor in deals from cashback sites as this cash is never guaranteed, and tracking problems occur for many people using cashback sites. If you do go via a cashback site, it's best to view any cashback as an added bonus. See our Top Cashback Sites guide for more.
The resellers we list are big, and generally have good feedback. The contract is still with the main network, so you get the same service, just via a cheaper source.
In the unlikely event a reseller went bust, don't worry - your contract will continue as normal as it's with the network (so there would be no change to your price or allowance of minutes, texts and data). The reseller is responsible for consumer rights on the handset though, so if there's a fault you'd need to rely on the manufacturer's warranty, or consumer rights via the payment card used.
We'll include special social tariffs in your results that are offered to those on certain benefits - do check eligibility criteria with the provider as it varies by firm.
