We joined and was told our smart meter wasn't compatible and we needed it swapping out. 2-3 months passed with no news which didn't overly worry me as this was at the start of the pandemic but I dropped them a message on Facebook, they got back to me quickly and told me the meter was sending readings and the installation had been cancelled. God knows when they'd have informed me if I hadn't messaged! Have to say other than the age my first Agile bill took they have been great other than that. I'd suggest dropping them a message on Facebook to see if that helps, but also a lot of meter installations are not completed by Octopus but third parties who they have no control over.
