I've been with Scottish power for a number of years and was given a smart meter soon after they were first available. All went well with them, other than the guy who installed them didn't know any thumping about how they worked and had no ad ice for me about using them. However all was good till August last year, when the gas smart meter became unresponsive, and refused to communicate with, either Scottish Power, or my unit in the kitchen. I reported this and was told an engineer would be in touch within three months. It's now March 2024 and I still have heard nothing. Plus I have no idea how much gas I'm using. I pay an estimated monthly amount, based on previous usage. I have spoken to head office in Glasgow, who told me I would hear spring 2024. I await action with interest.
