Since the Eon tariffs are fixed for a year its not a simple switch like Octopus non fixed rates, they do have a good whatsapp messaging service though so it should be easy to switch. Personally I switched to Eon last month and they are pretty responsive on there. The apps are not as polished as Octopus versions but benefit for me is the tariffs are fixed for a year giving much greater certainty over future rates and of course for those of us without an EV they are more accommodating and the export rate is better.
