If you have ever been stung by a surprise price increase on your pay monthly phone contract, there is good news. Ofcom has confirmed that its new rules banning inflation-linked mid-contract price hikes will come into force from 17 January 2026, following a consultation that began back in 2024.
What is changing
Under the new rules, mobile and broadband providers will no longer be allowed to tie mid-contract price rises to inflation measures such as CPI + 3.9%. Instead, any price increase must be stated clearly in pounds and pence at the point of sale, and customers must be told exactly when and by how much their bill will go up.
Providers can still raise prices during a contract, but they must do so in a way that is predictable and transparent. If they do not, customers will have the right to exit their contract penalty-free.
Why this matters
Mobile networks have relied on CPI-linked price rises for years, and with inflation peaking above 11% in late 2022, some customers saw their monthly bills jump by more than 14% in a single year. Ofcom said its research found that most consumers did not understand how inflation-linked hikes were calculated, and some did not realise their bill could go up at all.
What the networks are saying
- EE: Already moved to pounds-and-pence rises in April 2024 and has welcomed the new rules.
- O2: Was one of the few networks not to apply CPI-linked hikes and will continue its existing policy.
- VodafoneThree: Has confirmed it will comply but warned that "headline prices may need to rise" to compensate.
- Sky Mobile, iD Mobile, Tesco Mobile: All confirmed they will comply from the deadline.
Should you wait until January to sign?
It is a reasonable question. Any contract signed before 17 January 2026 will still be subject to the old rules for its full minimum term. If you are happy with your current handset, waiting a few weeks could save you hundreds of pounds over a two-year contract. However, if your phone is on its last legs or you spot a genuinely excellent Black Friday deal, the immediate savings may outweigh the long-term benefit.
Either way, this is one of the most significant consumer protection wins for UK mobile users in over a decade.
