Best UK mobile deals in 2026
The best mobile deal is the cheapest plan with enough data for how you actually use your phone, and head-term comparison is owned by sites like Uswitch and MoneySavingExpert. What we add is the sign-up saving: the VOXI referral code is a voucher worth up to £40 (doubled until October 2026; normally up to £20) and the giffgaff referral code is £5 in credit. Neither uses checkout codes. Affordable Mobiles is a reseller whose refer-a-friend scheme is currently paused; its savings are built into the contract price.

What are the best UK mobile deals in 2026?
For the networks we cover, the sign-up saving is a refer-a-friend reward rather than a discount code: VOXI gives a voucher worth up to £40 (double rewards until 7 October 2026; normally up to £20) and giffgaff gives £5 in credit. Neither runs public voucher codes. Affordable Mobiles' refer-a-friend cashback is currently paused; its deals are priced into the contract rather than a code you paste at checkout.
