A mobile phone contract can make owning a mobile (especially a smartphone) more affordable, by spreading the cost of a handset and airtime over monthly payments. But will you need a credit check? This article explains when a check is likely, what it shows lenders and what options exist if an application is turned down.

The networks named below are examples only, based on information on their own websites when we checked in September 2026. This article doesn't cover the whole market, and other providers may work differently.

Will I need a credit check to get a mobile phone?

Whether or not you need a credit check depends on the type of deal you want and the provider:

• Pay monthly with a handset: networks generally run a credit check. The handset part is often a separate credit agreement regulated under the Consumer Credit Act 1974. For example, O2 (Telefónica UK Limited) and Vodafone (Vodafone Limited) both describe their device plans this way, and both are authorised and regulated by the Financial Conduct Authority for consumer credit.

• SIM-only monthly plans: you'll usually still have a credit check, because you're billed monthly for a service you've already used. Vodafone, for example, says it runs a credit check whenever you apply for a new pay monthly device or plan. Not every provider does: giffgaff says that in most cases it doesn't run credit checks on its plans and SIM-only contracts, and only checks when a phone is bought on a loan.

• Pay as you go: you pay upfront for credit, so there's generally no credit check.

The check for a pay monthly contract is usually a hard search. A hard search leaves a footprint on your credit report that other lenders can see, and it normally stays there for 12 months. A soft search, which may be used for eligibility checks or to confirm your identity, is visible to you on your own report but not to lenders.

What credit score do I need to get a mobile phone contract?

There’s no specific minimum score needed to get a mobile phone contract; networks don't publish a minimum credit score. Instead, providers look at the information on your credit report, such as how you've managed credit and bills in the past, and apply their own lending criteria.

There are three main credit reference agencies (CRAs) in the UK: Experian, Equifax and TransUnion. Each uses its own scale:

• Experian uses 0–1,250, where 861–1,000 is "Good".

• Equifax uses 0–1,000, where 531–670 is "Good".

• TransUnion is moving from a 0–710 scale to a 0–999 scale between late September 2026 and June 2027.

A score from one agency can't be compared directly with a score from another. EE, Vodafone and Three each say they may use data from all three agencies.

Can missed phone bills affect my credit report?

Yes. Networks share information about how you run your account with the CRAs. EE, for example, says:

"A late payment will show when a bill is paid late. If your payment is 2 months late, it will show as ‘2’; 3 months late will show as ‘3’, and so on.

"A default happens if your bill is paid late for 6 months in a row. Your account will have been through the full collections cycle before we add a default. Since we’re not regulated by the Consumer Credit Act, we don’t have to notify you about a default or provide a copy of the original agreement.

"When you pay your account after a default your credit file will show as ‘satisfied’, but the default record will stay on your credit file for 6 years."

Can I check my credit report?

Yes. Checking your own report doesn't affect your score, and it lets you see whether your details are accurate. Because lenders may use any of the three CRAs, you can check your report with each of them. You can check your Equifax credit report and score for free with ClearScore.

Why might a mobile phone contract application be declined?

Common reasons for being declined for a mobile phone contract (that relate to credit history) include:

• Missed payments or defaults: a record of late or missed payments, or of debts that weren't repaid (defaults), can make lenders less willing to offer credit.

• Little or no credit history: if you've never used credit, lenders have less information to assess you with.

• Insolvency or court records: county court judgments (CCJs), individual voluntary arrangements (IVAs) and bankruptcy are recorded on credit reports and can make credit harder to get.

• Identity checks: if you've moved often or aren't on the electoral register, lenders may find it harder to confirm your name and address.

Having one of these on your report doesn't automatically mean an application will be declined. Some networks may ask for an upfront payment or deposit instead.

Eligibility and acceptance are decided by each provider and depend on its own criteria and checks. Checking your eligibility does not guarantee that you'll be accepted.

What happens if I apply again straight away?

Applying for a pay monthly contract usually leads to a hard credit search. Several hard searches in a short period can negatively impact your score for around six months and can suggest to lenders that you're relying heavily on credit.

Before applying again, you can check your credit report to see what lenders are likely to see. Check that your name, date of birth and address are correct. Under data protection law you can ask a credit reference agency to correct information that's inaccurate.

What other options are there?

If you can't get a pay monthly handset contract, other ways to get a phone include:

• A pay-as-you-go SIM in a phone you already own or buy outright. Since 17 December 2021, UK mobile companies haven't been allowed to sell locked handsets. An older phone may still be locked to its original network, which can unlock it.

• A SIM-only monthly plan. These usually still involve a credit check, but there's no handset cost included.

• A contract with a lower-cost handset, which means a smaller amount of credit, although a credit check will still normally apply.
