When i call my energy supplier, it does not ring but just says ‘Your Service Does Not Allow Access To This Number’.
The number I am trying to ring is 0800 520 02 02
I am calling from Denmark, but I have roaming and premium calls set up and have a lot of minutes left.

Hi there, can you please try entering 0044 or +44 before dialing the number? Alternatively, does your energy supplier have a number for customers outside of the UK?
