What to do when your mobile contract’s price rises

If your mobile bill has gone up while you're mid-contract, you're not alone.

Most mobile providers increase their prices by a small amount each year to combat upgrades and costs. But it's never great news when you have less money in your pocket.

The Retail Prices Index (RPI) rate of inflation announced in February 2024 was 4.9%, and the Consumer Prices Index (CPI) was 4%. This determined the price rise amount for the majority of mobile networks in 2024, many of which regularly add their own amount to this figure, too.

However, for any new customer joining a mobile provider from the start of 2025, Ofcom has banned price rises from being linked to the inflation rate. Instead, you'll likely be notified a fixed yearly price increase when you're signing up to the new deal.

Unfortunately, price rises are often built into the terms and conditions of the contract you sign with your provider. So what can you do when your bill rises unexpectedly? And what rights do you have when it does? Read on and we’ll explain how contract rises work and how you can learn to navigate them.

How often do networks increase prices?

Price rises tend to only happen once a year, with the major UK phone networks historically attaching their increases to the RPI or CPI rate, plus a regular amount that they will set themselves of around 3-4%.

But as previously mentioned - this will change to a fixed increase for new customers from January 2025, and it has already been implemented for new customers by some mobile networks.

In previous years, inflation-linked price rises used to mean a hike of anywhere between 4% and 5%. But after the UK inflation rate skyrocketed in 2022, 2024 still saw increases of at least 6% across the board, with some reaching over 8%.

On a typical £30 per month phone-and-SIM contract, an 8% rise would work out at about £2.40 more per month.

Price rises tend to be confirmed in January and February, before taking effect in March and April.

What should I do if I'm hit by a price rise?

You might be able to leave your contract free of charge, but it depends on the terms and conditions of your current contract.

Most networks are allowed to increase your monthly price because they mention it in your contract terms when you sign up. This usually means that you can’t simply cancel your contract without paying an early exit fee.

However, if your contract is at an end, you will be completely free to switch providers or ask for a better offer from your current network or to compare deals and switch to another network.

Some providers, such as Tesco Mobile, only increase prices after your initial contract term has ended. So you'll be free to switch by the time you see your bill go up anyway.

Do I have rights if I think I’m being ripped off?

Yes. Under Ofcom rules, you can quit without paying a penny if you can prove “material detriment.”

Ofcom says it is, “Likely to treat in-term increases to the core subscription price agreed at the point of sale as meeting this material detriment requirement and giving rise to the right of withdrawal". This is a very convoluted way of saying that having your price increased may mean you can switch to another deal without having to buy out the rest of your contract.

However, the bad news is that these yearly price rises are hard to prove as causing material detriment. So it's a bit of a tricky one. Your best bet would be to contact your mobile phone network to see if you can reach an agreement.

Do price rises affect SIM only deals as well as phone-and-tariff contracts?

Yes. Any stated annual price hike covers all kinds of monthly mobile contracts, whether they’re for a handset and line rental or a simple calls, data and texts only package.

The good news is that 30-day SIM only contracts can be left at short notice, meaning you can switch to a cheaper deal if you’re unhappy about your bill going up.

Should I switch to pay as you go

It depends. If you’re a light smartphone user, then pay as you go may be a decent option for escaping the vagaries of unexpected price rises.

But one-month SIM only deals, while susceptible to price rises, are a better bet.

30-day deals mean easily switching if you’re unhappy, with the added bonus of knowing your exact allowance each month.
