UK Mobile Consumer Rights: Your Complete Plain-English Guide

UK mobile customers have meaningful, enforceable rights. Many people don’t realise this because the rules are spread across several Acts of Parliament and Ofcom rulebooks. This guide puts them all in one place, in plain English, with the exact references you can cite in a complaint.

The Two Bodies of Law That Apply to Your Mobile Contract

Your rights come from two overlapping sets of rules:

1. The Consumer Rights Act 2015 (CRA 2015) — the general statute that applies to every service provided to a UK consumer. It requires services to be provided with “reasonable care and skill” (s.49), in a reasonable time (s.52), and at a reasonable price where no price was agreed (s.51). It also protects you against misleading pre-contract information.
2. Ofcom’s General Conditions of Entitlement — the mobile-specific rulebook that every licensed UK telecoms provider (mobile, broadband, fixed-line) must follow. Covered in depth in our Ofcom General Conditions guide.

If you have a dispute, the strongest complaints cite both.

Your Rights Before You Sign a Contract

Right to clear, accurate pre-contract information

Under Ofcom General Condition C1 and the Consumer Rights Act 2015, before you sign up the provider must clearly disclose:

• The monthly price — in pounds and pence, including the exact amount of any future mid-contract price rise (this rule strengthened in January 2025)
• The minimum contract term and any early termination charge
• The data/minutes/texts allowance and any fair-use limits
• Whether your phone will be locked to the network
• The complaints process and the Ofcom-approved ADR scheme

If the provider failed to disclose any of this, or disclosed it in a misleading way, that is a breach. You may have grounds to exit without paying an early termination fee.

Right to a 14-day cooling-off period

If you signed up by phone, online, or at a location that isn’t a physical store (a “distance” or “off-premises” sale), the Consumer Contracts Regulations 2013 give you 14 days from receiving your SIM or phone to cancel for any reason. The provider must not charge a fee, though they may charge pro-rata for any usage during those 14 days.

Crucially: if the provider failed to tell you about this 14-day right at the point of sale, the period is extended to 12 months.

Your Rights During the Contract

Right to an accurate bill

Your bill must reflect what you actually used and what the contract says you should pay. Billing errors — charges you didn’t authorise, a Device Plan still charging after the contract ended, promised discounts that never appeared — entitle you to a refund. The refund route is: (a) raise a formal complaint in writing, (b) give the provider up to 8 weeks, (c) escalate to ADR. See our O2 billing dispute guide.

Right to a reasonable level of service

Under CRA 2015 s.49, services must be performed “with reasonable care and skill”. If the signal at your home address is consistently unusable, or if the provider fails to deliver a service the contract promised, you may have grounds to exit the contract without an early termination fee. The evidence you need: (a) the provider’s own coverage map showing poor coverage at your address, and (b) a documented complaint log showing you reported the issue and they failed to resolve it.

Right not to receive unexpected mid-contract price rises

Since January 2025 (a major Ofcom rule change), any mid-contract price rise must have been disclosed in pounds and pence at the point you signed up. Not “RPI + 3.9%”, not an index formula — the actual amount. If your provider is trying to impose a rise that wasn’t disclosed that way, you have the right to exit the contract without an early termination fee.

Right to roaming transparency

Since Brexit, UK mobile providers can reintroduce roaming charges in the EU and elsewhere. They must disclose the charges clearly before you roam, and they must send you an SMS with the applicable charges when you first connect to a foreign network. Providers must also have a reasonable-use or bill-cap mechanism for data to prevent bill shock. If charges weren’t properly disclosed, you can dispute them.

Your Rights to Leave

Text-to-Switch (Ofcom GC C4)

Since 1 July 2019, every UK mobile provider must support Text-to-Switch. To leave, you text:

• PAC to 65075 — if you want to keep your mobile number
• STAC to 75075 — if you don’t want to keep it
• INFO to 85075 — to get your contract end date and any early termination charge

The provider must send the code within one minute. The code is valid for 30 days. You do not have to speak to a retention team, and you do not need to give a reason. See our detailed PAC code guide.

Right to end-of-term cancellation

At the end of the minimum term, you can leave with 30 days’ notice and no early termination fee. Before the end of the term, you’ll normally pay an ETC covering the remaining months (often at 90–95% of the remaining monthly costs). Our O2 cancellation guide has the specifics.

Your Rights When Things Go Wrong: The 8-Week Rule

Every UK mobile provider must operate a clear complaints process (Ofcom GC C5). The framework is standardised:

1. Raise a formal complaint — ideally in writing. Give the provider a reasonable deadline (14 days).
2. If unresolved, ask for internal escalation.
3. After 8 weeks of an unresolved complaint, or on receipt of a written deadlock letter, you have an automatic right to take the dispute to the provider’s Ofcom-approved ADR (Alternative Dispute Resolution) scheme.
4. ADR is completely free to you. The ADR scheme’s decision is binding on the provider if you accept it.

We have free complaint letter templates (formal complaint, deadlock request, ADR submission) ready to use.

Which ADR scheme handles your provider?

• Ombudsman Services: Communications (OSC) — O2, EE, BT, Three, Sky, Plusnet
• CISAS — Vodafone, TalkTalk, Giffgaff, iD Mobile

When You Can Exit a Contract Without an Early Termination Fee

The headline circumstances where you may exit without paying ETC:

• The provider materially changes the terms to your detriment (Ofcom GC requires the provider to notify you and give you a one-month exit window).
• The provider imposes a mid-contract price rise that was not properly disclosed at sign-up (January 2025 rule).
• The provider breaches a material term, e.g. fails to provide a reasonable level of service at your address.
• The provider fails to resolve a complaint through ADR and the ADR awards contract release as a remedy.
• You’re within the 14-day cooling-off period of a distance/off-premises sale.

Rights Specific to Billing and Money

Right to challenge third-party charges

Premium-rate numbers, subscription services, and charges from third parties billed through your mobile account are regulated by the Phone-paid Services Authority. If you didn’t authorise a charge, your provider must investigate and, where appropriate, refund it and dispute it with the third party.

Automatic compensation

Ofcom’s Automatic Compensation scheme (GC C7) applies primarily to broadband and landline: £8.40 per day for total loss of service after 2 working days, £5.20 per missed engineer appointment, and so on. Several mobile providers have voluntarily adopted similar principles but it is not yet universally required for mobile.

Your Rights Around Your Personal Data

Under the UK General Data Protection Regulation and the Data Protection Act 2018 you have the right to:

• Access a copy of the personal data your provider holds about you (Subject Access Request — must be fulfilled within one month, free for most requests)
• Rectification of inaccurate data
• Erasure (“right to be forgotten”) in certain circumstances
• Restriction of processing while a dispute is being resolved
• Data portability
• Object to direct marketing

If the provider handles your personal data wrongly and won’t put it right, you can complain to the Information Commissioner’s Office at ico.org.uk.
