Hi, just signed up having searched online for help. I'm going slowly mad trying to sort this problem as I am getting different info from different people and I need a level of expertise that I am struggling to find. I'm hoping someone here can help. I had a smart meter (2nd gen) installed 18mths ago. I was with EDF and all was good. Then I swopped to Bulb and months later discovered (because I was away and was still running up sizeable day rate bills) that I was being charged for E7 between 00.30-07.30 GMT but my storage heaters were still coming on at the EDF times of 22.30-00.30 and 02.30-07.30. So they were charging primarily during that first EDF time whilst, as far as Bulb were concerned, that was Rate 1 or Day rate. My housing association have an energy advice department and I have been working with one of their advisors. I have provided Bulb with all the evidence that this what is happening. At first they just said, sorry can't help, those are the times we offer. The advisor and the electrician I consulted both said it should be automatic, although no one seems too certain exactly how, these days, the timer/meter knows the times. I don't think it is a radio signal anymore, not with smart meters anyway. When I went back to Bulb and said it should be automatic so it must be the timer or the meter (which is what the advisor and electrian told me) they said, no, you have to sort that in your home. I repeated back to Bulb the advise I had had that is was a meter/timer problem and then they said, we'll need a report from an electrican to that effect. It's as though Bulb don't know anything about how it works! Or I am being giving duff info. I am concerned that if I get a report from the electrician and they send an engineer and it doesn't solve the problem, that Bulb will send me the bill. The electrician is very busy and not it seems very interested and can't do me a report for at least a couple of weeks. I am going on his information and I find myself wondering if his info is fully up to date. The advisor doesn't really know what to say next. According to everything he knows this is a meter or timer issue. He has checked with colleagues who agree but he says himself he has never come across this problem before. So what I really need is for someone who really knows how these things work and is up-to-date with the effect of second gen smart meters on E7 wiring to tell me for sure firstly, how the instruction to turn on at the right time gets to the E7 switch? Secondly, and if it's not working where is the problem going to be? The electrician checked all the general wiring a few weeks back and said it is fine. I reckon Bulb owe me about £100 in overpayment but if push comes to shove I will just change to a company that offer the same times as my system is set to. That would not solve the problem but it would circumvent it. Can I politely ask that people only answer if they are very certain of their facts as I have heard every theory going, what I need is solid knowledge. Many thanks in advance.
