Since 2020, Ofcom has required UK mobile providers to separate the cost of your device from your airtime plan. This was designed to stop you overpaying once your phone is paid off — but the reality is more nuanced. Many consumers still don't understand the split, and some contract structures make it harder than it should be to benefit from the change. Before you sign a new phone contract, understanding how the device plan and airtime plan interact, when each ends, and what happens next can save you hundreds of pounds.
What is a Device and Airtime Plan Separation?
A separated device plan is a credit agreement for the phone itself (regulated by the FCA as a consumer credit agreement), while the airtime plan is a separate contract for calls, texts, and data. Ofcom's Fairness Framework, implemented from February 2020, required this separation to ensure consumers see exactly what they're paying for the device versus the service. When the device plan ends (typically after 24-36 months), your monthly payment should drop to just the airtime cost. The device plan is a form of consumer credit, meaning it's regulated under the Consumer Credit Act 1974.
Red flags to watch for
If you can't see exactly how much you're paying for the device versus airtime, you can't verify when the device cost ends and your bill should drop.
Some providers don't automatically reduce your bill when the device is paid off. You continue paying the device cost as pure profit to the provider unless you actively switch or complain.
If you leave early, you should owe the remaining device cost (that's fair) plus any notice period on the airtime plan. But some contracts add penalties on top.
Because the device plan is a credit agreement, the provider must disclose the APR. Some plans advertise '0% interest' but inflate the device price above retail, effectively charging hidden interest.
If the airtime contract is locked for 36 months because that's how long the device plan runs, you can't switch to a cheaper airtime deal even after 12-18 months when better deals are available.
Your legal rights
Ofcom's Fairness Framework and General Conditions of Entitlement require providers to separate device and airtime charges, notify customers when their minimum term ends, and provide clear information about what happens next. The Consumer Credit Act 1974 regulates the device plan as a credit agreement — you have a 14-day withdrawal right from the credit agreement. Ofcom's end-of-contract notification rules (effective since February 2020) require providers to notify you when your contract is ending and tell you the best available tariff. If you're unhappy with your provider's handling, you can complain to Ofcom or the relevant Alternative Dispute Resolution scheme (CISAS or the Communications Ombudsman).
