What Ofcom changed
Since January 2025, providers offering new contracts with scheduled in-contract rises cannot describe those rises using inflation-linked formulas or percentages. If a contract contains a specified future rise, it must be shown clearly in pounds and pence before you sign up.
Can you leave penalty-free?
It depends on your contract. Ofcom explains that if a provider raises the price beyond what you agreed, it generally must give at least one month’s notice and a right to exit without penalty.
But if the future increase was clearly set out in pounds and pence when you signed up, applying that agreed rise does not automatically create a penalty-free exit. The old MoneySavvyUK article’s universal “30-day escape window” wording has therefore been removed.
If you want to switch
Check whether you are still in your minimum term and whether an early termination charge applies. If keeping your number, you can use the PAC switching process. Compare allowance, coverage, roaming, contract length, handset costs and scheduled increases — not only the headline monthly price.
If affordability is the problem
Check whether you are paying for more data or services than you need and compare SIM-only options. If you’re struggling with household connectivity costs, our broadband price rises and social tariffs guide may also help.
