I've got the exact same meter & it's defo a SMETS 1. I've been moved to Shell Energy (old supplier went down the pan) and they're saying they can connect to it :S. I just want to get a SMETS 2 meter fitted so can switch to Octopus but they're not playing ball. Not sure how I can force them to ??
I could switch to Octopus without a SMETS 2 meter and wait for them to install one but I'll be put on a super pricey tariff and they're in no rush to install a new one.
