Mobile operator Three UK (VodafoneThree) recently began notifying some of their existing customers that, from 1st April 2026, they will be updating their annual price increase terms to a “more transparent approach“, which moves away from % based price rises and uses amounts shown in pounds and pence. But it won’t impact everybody, yet.
The change, which is in line with Ofcom’s new policy (here), was first technically introduced by Three UK (and Vodafone) back in early November 2025 (here). But at the time that only applied to new customers, while the latest change extends the policy to some existing customer. The exact increase customers see will be dependent on when your current contract started (this may be when you joined Three or last upgraded your account) – details.
However, customers who joined or upgraded their phone, SIM Only, Mobile Broadband or Home Broadband plan between 1st November 2022 and 7th September 2024, and are still within the minimum term of your contract on 31st March 2026, will still be subject to an increase each April by the preceding December CPI rate of 3.4% + 3.9% (total increase of 7.3%). Otherwise, it’ll be the pounds and pence method.
Three UK Statement
“From 1st April 2026, we’re updating your annual price increase terms to a more transparent approach, which moves away from % based price rises and uses amounts shown in pounds and pence, so that you can see more clearly what the change to your monthly charge will be from April each year.
…
Similar to many other mobile providers, our Pay Monthly plans are subject to an annual price change. The increases reflect inflationary pressures we are facing as a business including energy prices, supplier increases, and increased staffing costs. Despite this change, our prices remain some of the most competitive in the market and we have a range of support, including a social tariff via SMARTY, available for customers struggling with their finances.”
Three UK’s new mid-contract price rises (extra monthly charge):
Low (4GB and below): £1.80
Mid (5GB and above, below 100GB): £1.90
High (100GB+): £2.30
Home Broadband: £3.50
Smartwatch Pairing Plans: £1.80
