I'm currently with SSE not with SP but we have 2 meters and one MPAN ie only one supply so only one set of standing charges. It is also a business supply to a farm; although I have been in contact with SSE and can change it to a domestic supply if that is what we want to do. For us, the 2 meter situation is a legacy from when 'we' had machinery that required a soft start using 2 suppplies then droppping down to one. We no longer have the mixer in question (actually we've never had it, grandad did). So having 2 meters might be a leftover from when the property was a working farm/croft, not just to do with economy 7 or 10. You might think that having 2 meters had something to do with the house being on one and the steading being on the other. That may be the case in some situations but not in our case. For us there is no rhyme/reason as to what is wired to which meter. What we have is not a problem for us. Unfortunately your only recourse to sort out any problems you do have is to engage with your supplier and hang on in there until it's sorted. A full check and condition report from a competent electrician who can explain what you have and why may help your case with your supplier.
@Chutney86 Very unusual, do both the meters record the same readings? British Gas are usually very good in these situations and I think you need an engineers visit to sort it out. Maybe if you apply for a smart meter the issue would get dealt with when the new meter is installed. I'm sure they would not install 2 smart meters.
We're having the same problem, i.e., 2 electric meters, one property, two accounts, 2 lots of standing charges. Historically one of the meters was originally part of a granny flat which has long been incorporated into the main house, but SP is saying it's impossible to merge the accounts so we have to keep paying 2 lots of standing charges on the same property. Needless to say, with the current price rises, this has become a serious problem. Any suggestions from anyone on this forum? Many thanks.
@Nigel1 Difficult problem, but you could close the granny flat account and get an electrician to supply those rooms from the main consumer unit fed by the main meter. Alternatively get away from Scottish Power because they are hopeless at problems like yours, Octopus Energy would sort it out quickly for you.
