How does Uswitch calculate its savings messages?
Around the site, you'll see that we use examples of the great savings you could make when you compare and switch with Uswitch.
These figures are intended to be an indication of how much money you might be able to save, and are based on averages of real savings we've provided to our customers. No two households are the same though, so you could find that your savings might be less or maybe even more than the amounts we use in our examples.
You can find the details of how we calculated these savings in the table below.
| Product | Potential savings | How was the potential saving calculated? |
|---|---|---|
| Broadband | £329 average | Switching to a new broadband deal after your initial contract has ended could save you £329 (£329.15) a year.* We calculated the average yearly cost of staying out-of-contract (£657.60) across the five most popular deals on Uswitch: Vodafone Full Fibre (500, 150, and 910) and Virgin Media (Gig1 and M125). We compared this to the average yearly cost for new customers switching to those same five deals (£295.15). This figure includes mid-contract price rises, calculated using the average price increase across these five deals (£3.70 per month) applied to the 9 months of the year following the April price hike (April to January). |
| Mobile phones (handset contract to SIM Only) | £304 per year average | Switching from an ending 24-month handset contract to a SIM-only contract (and keeping your existing handset) could save you £304 (£304.54) per year, or £25.38 per month. This calculation is based on the price of the top selling 24 month handset package in Jan 2024 (Apple iPhone 15 with Unlimited data) against the cheapest equivalent SIM only deal on the Uswitch site as of Jan 2026 (iD Mobile Unlimited Data £15.00 per month, 24 month contract). Correct as of Jan 22 2026. |
| Mobile phones (handset contract to handset contract) | £84 per year average | Switching from an existing handset contract to a new handset contract with a top smartphone could save you £84 per year, or £7 per month. This calculation is based on the price of the top selling 24 month handset contract on Uswitch.com from Oct 2021 (Apple iPhone 13 Pro with 100GB data), against the most popular 24 month handset contract on Uswitch.com in Oct 2023 with a similar amount of data (Apple iPhone 15 with 100GB data). |
| Balance transfer credit card | £713.71 for the first 12 months | Representative example calculated using the median interest rate of cards on our site and the median balance request from our customers looking for a balance transfer card using our eligibility checker in June 2025. Terms offered depend on your financial circumstances and borrowing history. Interest rates and zero-interest balance transfer period may vary. Correct as of 1 July 2025. |
