I just spoke to Andy in the complex metering team at EDF and was informed that EDF no longer install Economy 10 meters. I was told that if I switched to Economy 10 with my current provider, they’d be able to accept me.
When I asked for current Economy 10 pricing, the call dropped. It’s not unknown for my mobile to drop calls, so I can’t say for sure whether it was bad timing, or the agent hung up on me.
So, I think it’s fair to say the “full support” tag for EDF needs to be removed.
