12 month phone contracts are the rarest commitment length on the UK market in 2026, but they do exist and they're a smart choice for anyone who wants a new handset without locking in for two or three years. This page rounds up every 12-month handset contract from across the UK networks and resellers, updated daily, so you can compare upfront costs, monthly prices and data allowances at a glance.
12-month handset contracts are uncommon because the phone's cost has to be amortised over half (or a third) of a normal contract, which pushes monthly prices significantly higher. Tesco Mobile is the exception: almost every phone in its range, flagships included, is sold on a 12-month Anytime Upgrade Flex term alongside 18, 24, 30 and 36 months (a few budget and basic phones are 24-month only). iD Mobile occasionally runs 12-month handset deals, and resellers have offered short-term contracts on selected handsets, but the headline networks (EE, Vodafone, O2, Three) almost exclusively sell 24 and 36 month plans for new phones.
If a 12-month contract isn't available on the handset you want, the standard workaround is a split contract: buy the phone outright (or on 0% interest finance over 24 months from Apple, Currys or Argos), then add a separate 12-month SIM-only plan. You get the same flexibility, often at a lower total cost.
Should you choose a 12 month phone contract?
12-month phone contracts trade lower commitment for higher monthly cost, and whether that trade-off makes sense depends on your circumstances. Most UK handset contracts run for 24 months because that's the period the network uses to spread the cost of the phone, with some flagship deals stretching to 36 months to bring the headline monthly price down further. Cutting that period in half (or to a third) means each monthly payment has to cover more of the handset, so the price goes up.
How much more? On a £999 flagship like the iPhone 17 or Galaxy S26, a 12-month contract typically costs £25 to £40 more per month than the 24-month equivalent with the same data allowance and upfront fee. Over the full term you may pay slightly less total because you stop paying after a year, but the monthly bill is uncomfortably high for most households.
The flexibility benefit is real though. After 12 months you can switch network, upgrade to a newer phone, drop to SIM-only or cancel entirely with no early termination fee. If your job, location or budget might change within two years, that flexibility can be worth the premium. It's also useful if you're buying for a child or student where 24 months feels too long.
Tesco Mobile is the UK network with the widest 12-month range: its Anytime Upgrade Flex plans pair a 12-month 0% credit agreement for the phone with a rolling monthly airtime contract, and the 12-month term is offered on nearly every handset it sells, from the Galaxy A17 to the iPhone 18 Pro Max (a few budget and basic phones are 24-month only). iD Mobile has run 12-month deals on selected Samsung A-series and Motorola phones, and resellers like Affordable Mobiles and Mobile Phones Direct occasionally surface short-term contracts on grade-A refurbs.
Split contracts are the workaround most savvy buyers use in 2026. You finance the handset over 24 months at 0% APR through Apple, Samsung, Currys or Argos, then pair it with a 12-month SIM-only plan from Smarty, iD Mobile, Lebara or Voxi for £6 to £15 per month. Total monthly cost is usually lower than a 12-month bundled contract, and you can still switch SIM plans every year. Vodafone Evo is Vodafone's own version of this idea: a flexible handset finance term (typically 3, 12, 24 or 36 months) paired with a separate airtime plan you can change monthly.
Refurbished phones also change the maths. A grade-A refurbished iPhone 15 or Galaxy S24 costs roughly half the price of the latest model, so a 12-month contract becomes much more affordable. Merchants like Reboxed and 4Gadgets surface 12-month deals on certified refurbs that compete well with new 24-month plans on the same handset.
