Octopus asked to change/upgrade my smart meters despite them working fine. They then bodged the installation and didn't commission them properly before leaving my premises. They then spent several months messing me around before they eventually resolved the issues. They then claimed that under the standard terms and conditions they were able to charge me at the standard variable rate for the entire period when half hourly readings were not available. As a customer on Intelligent Octopus with a home battery and an EV, these additional charges added over £530 extra to my bill!! Octopus have offer a customer service gesture to cover approx half of this cost, but why should I be paying for their incompetence. I've provided them my own half hourly data from my home battery system which allows them to identify the exact amount of energy used during peak and off peak periods!
