How to complain to Tesco Mobile

Start with Tesco Mobile's customer services, then make a formal complaint if it isn't sorted. Tesco Mobile's complaints process is set out in the complaints code on its website (search for "complaints code"). Keep a note of the date you complained and any reference number.

Ofcom says every provider's complaints code must include a phone number, a UK postal address and an email address or web form for complaints.

Tesco Mobile price rises

Tesco Mobile

When: April each year. How it's set: Clubcard Price deals: price frozen for the minimum term. Other plans: a pounds-and-pence rise shown when you sign up (since 17 December 2024); the amount depends on your plan. Latest: Out-of-contract customers (minimum term ended before 1 February 2026) got a rise from April 2026. Amounts vary by plan: check your contract.

Ofcom's rules mean price rises in contracts taken out from 17 January 2025 must be set out in pounds and pence. If a rise wasn't set out in your contract, or is bigger than it allowed, Ofcom says the provider must give at least 30 days' notice and let you leave within 30 days without exit fees.

Cancelling or leaving Tesco Mobile

If your minimum term has ended, you can usually leave by giving the notice your contract requires. If you're still in contract, early exit charges may apply, so check first.
Mobile: text "PAC" to 65075 to get a code to switch and keep your number, or "STAC" if you don't want to keep it.
Near the end of your contract, Tesco Mobile must send you an end-of-contract notice with your current and future price and its best deals.

If Tesco Mobile doesn't sort it out

Ofcom lists Tesco Mobile as a member of the Communications Ombudsman, one of the two free alternative dispute resolution (ADR) schemes for phone and broadband. You can go to it once at least six weeks have passed since you first complained, or sooner with a deadlock letter, and within 12 months of a deadlock letter. (For complaints made before 8 April 2026 the wait was eight weeks.)
