We (CompareDial Ltd) are an independent company. We are not owned by, nor have we received investment from, a provider, network or retailer. Our algorithm is unbiased and does not favour providers, networks or retailers.
We may earn a commission whenever you click on a link listed through our website and continue to make a purchase. Our algorithm for fetching and showing results is not influenced by the amount of commission we receive, nor is our editorial content.
For more information about CompareDial, please see our about page.
An explanation on how we calculate costs can be found here.
Prices shown can change at any time and may be different elsewhere, such as on external websites and competing comparison tools.
For information about our sorting algorithm, click the 'i' (information) button next to the sort options on this page.
All stated monthly costs assume you will pay by direct debit. A provider may charge more if you choose an alternative payment method.
Missed monthly payments may incur a penalty from your provider. Your credit score may also be affected.
If you go over your stated allowance or use a service not included within your allowance, your provider may charge you at an additional out of plan rate.
We aim to show most costs associated with a contract, however we may not show more granular costs, such as international rates, roaming rates and some out of plan rates.
Cashback is shown whenever it is available. Cashback is paid by the provider. Redemption cashback must be manually claimed, usually in installments.
All prices shown include VAT.
If you spot a mistake on our website, or think something is inaccurate, please contact us so we can fix it as soon as possible.
If you have a complaint about us (CompareDial), please see our complaints page for contact information.
Contracts may be subject to fair usage policies and traffic management policies. Where possible, we will provide links to the provider’s terms and conditions for acceptable use.
We do not show legacy tariffs, deals exclusively for existing customers, upgrade deals or deals included with other bundles. We only show contract deals that are available for all customers.
For phone and SIM only deals, we only show contracts that are 30 days / 1 month or longer.
Prices shown can change at any time, and may differ on a provider’s own website or app.
Providers can increase the cost of your contract in line with RPI (inflation). If you believe an increase is either excessive, unfair or wasn't stated clearly in your contract, you may be able to exit your contract without penalty. For more information, see Ofcom’s guide on unexpected mid-contract price rises. You can also make a complaint through Ofcom.
We try to include as many deals as possible, however our results do not represent a complete overview of the market. If you’re a retailer or network and you wish to be included in our results, please contact us.
For more advice related to consumer phones and contracts, please visit Ofcom consumer guides.
Ofcom runs a voluntary accreditation scheme for digital comparison tools (DCTs) for telephone, broadband and pay-TV, and has confirmed that this DCT meets the criteria for accreditation. For further details about the scheme, including the criteria that DCTs must meet, visit the price comparison page on the Ofcom website.
