How broadband speeds are measured

Broadband speeds are measured based on the number of megabits (blocks of data) downloaded in a second. When you check the availability for an address with Vodafone, we'll give you four speeds:

  1. The estimated maximum download speed that your line is likely to achieve
  2. The estimated minimum download speed that your line is likely to achieve
  3. The Openreach Minimum Speed - if you are getting lower than this you may have the right to terminate your contract
  4. The Ultimate Speed Guarantee relevant to your chose package.

How do I claim money off with the Ultimate Speed Guarantee?

If your service meets all the above criteria then the Vodafone Broadband app will show the 'Claim' button in the Info and Support section under the 'Sync speed'. Simply select the button and we'll do the rest.

The credit amount will not be pro-rated and you will receive 15% of the monthly subscription cost off your Home Broadband package. The discount will not apply to Home Phone line rental or call charges. Any credit will apply to your next bill and will last until your sync speed increases or you change the package that you are on.
