Up to 15.6 million O2 mobile customers are finding out their bills will rise by 40% more than they were told.
The original £1.80 a month rise will now be 40% more at £2.50 a month (so £30 a year). As it’s a flat rise for all contracts, those who are on less expensive plans will be disproportionately impacted. Some will see their calls, texts and data (airtime) plan costs increase by nearly 30%.
Even those on O2’s most expensive airtime plan, which currently costs £34 a month, will see a rise of 7.4% – far above the current 3.8% Consumer Prices Index (CPI) rate of inflation.
Almost all O2 customers on both mobile and Sim-only contracts will therefore see their bills rise by £2.50 a month from April 2026, regardless of whether they’re mid-contract or out of contract at the time.
