  • More than 1.6 million mobile and broadband customers risk overpaying as their contracts expire this month[1]
  • Mobile customers could save as much as £321[3] a year by switching to a new SIM only deal
  • Switching to a new broadband deal could save consumers an average of £203[4]  over the course of a year
  • Uswitch encourages Brits to check if their contract is due to expire this November and see if they can save by switching to a cheaper deal

Over 1.6 million mobile and broadband customers are warned they could be at risk of overpaying on their bills from this month, with a huge number of deals set to expire in November[1].

New analysis by Uswitch, the comparison and switching service, highlights the urgency of checking contract end dates ahead of the Black Friday sales period. This is a key time because mobile and broadband deals often run on a 12 or 24-month cycle, meaning the Black Friday shopping period is also the key expiration window for millions of customers.

Broadband customers who let their fixed-term contracts lapse are often rolled onto more expensive rates, which can be up to 70% more costly[2]. Switching to a new broadband deal can save consumers an average of £203 over a year.

Most at risk are the hundreds of thousands of customers whose bundled mobile contracts - combining handset and airtime - are about to expire. When you take out a bundled phone contract, you are effectively paying off the handset cost with your monthly bills. Once your initial contract ends, you’ve legally finished paying off the device - yet for many, this won’t be reflected in their monthly payments. Some customers will continue to pay the same amount as before, if not more, for a phone they now own outright.

For mobile users who are happy with their current phone, moving to a SIM Only plan is the quickest way to cut costs. By moving from a lapsing 24-month handset contract to a SIM Only deal, the average customer could save around £321 a year[3].

If you do want a new handset, it’s always worth shopping around to find the best deal or directly contacting your provider to negotiate a deal on an upgrade. 

Ernest Doku, telecoms expert at Uswitch.com, comments: “November is one of the most important months of the year to check your contract status. With over 1.6 million consumers estimated to be coming to the end of their existing deals, this is the window where you can bag a Black Friday bargain and save hundreds of pounds. 

“The key is to act now - before your contract automatically rolls over onto a more expensive monthly rate. For mobile customers, don’t pay for a phone you own - a simple switch to a cheaper SIM Only plan could save you hundreds. For broadband users, start comparing deals now to get your new service in place before the sales end.

“Mobile customers can check whether they are in contract or not by texting “INFO” to 85075. If you do choose to switch providers, you can still keep your old mobile number. Just text “PAC” to 65075 for free and you will receive your PAC code. Once you receive the PAC code from this number, give it to your new provider and they will do the rest.”

Notes to editors

  1. Out-of-contract figures are based on internal Uswitch analysis of customer contract end dates for mobile handset, SIM-Only, and broadband deals set to expire in November 2025 versus market data.
  2. This calculation is based on the average 12-month out of contract cost calculated in July 2025 between the five most popular new deals on Uswitch: Vodafone Full Fibre 150, Virgin Media M125 Ultrafast Fibre broadband only, Sky Superfast Broadband, Sky Full Fibre 500 and Vodafone Fibre 2 (£524.40), compared to their average yearly in-contract cost for new customers (£308.38), minus the average mid-contract price increase amount between each deal for 5 months post-price increase. Correct as of 30 July 2025.
  3. Switching from an ending 24-month handset contract to a SIM only contract (and keeping your existing handset) could save you £321 (£321.67) per year, or £26.81 per month. This calculation is based on the price of the top selling 24 month handset package in July 2023 (Apple iPhone 14 with 100GB data) against the cheapest equivalent SIM only deal on the Uswitch site as of July 2025 (iD Mobile 108GB data £9 per month on average ). Correct as of 30th July 2025.
  4. Switching to a new broadband deal after your initial contract has ended could save you £203* (£203.17) a year. This calculation is based on the average 12-month out of contract cost calculated in July 2025 between the five most popular new deals on Uswitch: Vodafone Full Fibre 150, Virgin Media M125 Ultrafast Fibre broadband only, Sky Superfast Broadband, Sky Full Fibre 500 and Vodafone Fibre 2 (£524.40), compared to their average yearly in-contract cost for new customers (308.38), minus the average mid-contract price increase amount between each deal for 5 months post-price increase. Correct as of 30 July 2025.

*This figure includes mid-contract price rises. This is calculated using the average current mid-contract price rise for the five most popular new deals (£2.57 per month) , multiplied by 5 (as of August, 7 months left till MCPRs come into effect, so the figure includes 5 months of increased prices, March to July).
