I was wondering when I will be getting a smart meter as all my friends seem to have them with other suppliers
Check out the Help page at: https://help.bulb.co.uk/hc/en-us and follow the link “You can switch to Bulb with a smart meter”. I would guess your friends have first generation smart meters which are not fully compatible between energy suppliers.
There have been numerous postings asking the same question as you, please do a search of the forum.
