With having a large family it has always made sense for us to be on Economy 7 and use our appliances overnight - we do not have storage heaters. I gather Economy 7 is only worthwhile if the units used overnight are around 25% to 30% of the total so, as ours are borderline, we are thinking of going onto a single tariff. DD3 and the children , obviously, increase our usage quite considerably but look as though they will be moving out soon.
I would like to know whether the meters would need to be changed if we changed tariffs?
I would welcome losing the 'tyranny' of Economy 7.
Thanks for your help!! And, any suggestions of good and bad companies would be nice too! 
What is you oldest item of clothing, handbags or shoes ?
