The O2 price rise that got Ofcom to speak up
Most mid-contract price rises pass without much fuss. The O2 price rise announced for April 2026 didn’t. O2 increased its yearly mid-contract rise from £1.80 to £2.50 a month, an increase customers hadn’t been told to expect when the previous year’s rise was set, and it drew public criticism from campaigners, MPs and Ofcom itself.
None of that means O2 broke the rules. It didn’t. What it exposed is a gap in the rules that’s now under formal review, and that gap matters for every mobile customer, not just O2’s.
What did Ofcom actually say about the O2 price rise?
Ofcom said it was “disappointed” by O2’s decision, adding that the move “goes against the spirit of our rules which are designed to ensure greater certainty and transparency for customers when they sign up.” That’s unusually direct language for a regulator commenting on a single supplier’s pricing decision.
The government got involved too. The technology secretary wrote to Ofcom asking for a rapid review, and the Chancellor called telecoms bosses in for a meeting about customer fairness. For a routine annual price adjustment, that’s a lot of attention.
How did the O2 price rise stay within the rules?
Since January 2025, Ofcom has required providers to show planned mid-contract price rises in pounds and pence at the point of sale, rather than burying them in a vague inflation-linked formula. O2 did disclose a rise. It just set next year’s figure higher than the year before, and there’s currently no cap stopping a provider doing exactly that. The O2 price rise followed the letter of the rule while stretching what most people assumed the rule was for.
That’s the gap the O2 price rise exposed: pounds-and-pence disclosure tells you a number is coming, but nothing stops that number climbing sharply from one year to the next.
What are your rights if your provider raises prices mid-contract?
If a price rise counts as “materially detrimental” under Ofcom’s rules, you can usually leave penalty-free, even mid-contract. The catch is that this generally only applies to specific circumstances set out in your terms, not simply because you’re unhappy about the size of an increase.
Check your own contract’s terms for how it defines a rise as fair or unfair, and read the notice you were sent when you signed up. Full details on exit rights, deadlines and how the pounds-and-pence rule works are in our mid-contract price rises guide. If a formal complaint is heading nowhere, our guide to mobile network complaints covers how to escalate it properly. Several networks have also signed the voluntary Telecoms Consumer Charter, which commits to phasing out these rises for existing contracts, though it’s voluntary rather than a hard rule.
Where does the regulatory review stand now?
Ofcom’s interim review of the pounds-and-pence rule was due in spring 2026, with options on the table including a cap on how much prices can rise or stronger exit rights for customers. A fuller review is expected to follow. Nothing has changed the underlying rule yet, so pounds-and-pence disclosure without a cap remains how the market works for now. The O2 price rise is the case study that pushed the review onto the agenda in the first place.
Worth keeping an eye on if you’re locked into a long contract: any changes coming out of the review are likely to affect new contracts first, not necessarily rewrite the terms you’ve already signed.
Key takeaways
- O2’s mid-contract rise (£1.80 to £2.50 a month) complied with the rules but drew an unusually direct rebuke from Ofcom.
- The pounds-and-pence rule requires disclosure of a rise, not a limit on how much it can be.
- Ofcom’s review of the rule was due in spring 2026, with a cap or stronger exit rights among the options.
- You can usually exit penalty-free only if a rise counts as “materially detrimental” under your specific terms.
- Any rule changes from the review will most likely affect new contracts before existing ones.
Frequently asked questions about the O2 price rise and your rights
- Can I leave my O2 contract early because of the price rise?
- Only if the rise meets the “materially detrimental” threshold in your specific contract terms. A rise disclosed in pounds and pence at sign-up, even a larger one, doesn’t automatically qualify.
- Did Ofcom fine O2 over the price rise?
- No. Ofcom criticised the decision publicly but confirmed O2 stayed within the current rules, so no fine or formal enforcement action followed.
- Will Ofcom cap mid-contract price rises in future?
- Possibly. A cap is one option under review following the O2 case, alongside stronger exit rights, but no final decision had been confirmed by September 2026.
- Does the Telecoms Consumer Charter stop rises like O2’s?
- Only for providers that signed it, and only as a voluntary commitment covering legacy contracts. It isn’t a binding rule enforced across the whole market.
- How do I check if my own contract has a similar price rise built in?
- Look at the pounds-and-pence figure you were shown when you signed up, usually in your contract summary or welcome email, and compare it to what’s actually been applied.
Whatever the review decides, the O2 price rise is a decent reminder that comparing what else is out there costs nothing and takes a minute.
