My tenants in a Kenilworth flat switched to Octopus. After 6 months Octopus came to replace the meter, I had no say in the matter. On May 31st the poor tenant rang in alarm when he was told the gas supply was being cut off and he would be unable to cook. The reason the technician gave was that the 'boiler looks unsafe'. But I'd had the annual boiler safety check done only a week previously and both I and the tenant had copies. The safety certificate was issued by a qualified and experienced gas engineer, while the Octopus technician is only trained in changing meters. He had seen marks on the wall made when the boiler was installed in 2017 and somehow imagined them to be significant. This technician cut the gas pipe to the boiler. My engineer was disgusted, saying similar things had been done to other customers by Octopus when changing meters. Octopus staff are told to cover themselves by cutting off gas supply if they have any safety doubts, but they don't have the training to assess safety. I had to pay the engineer to visit, restore the supply and re-issue the safety certificate. I immediately complained to Octopus and they have effectively done nothing, with 'holding' replies for 3 weeks.
