At risk of repeating myself, I really don't think that there is anything for you to worry about. If any new supplier is prepared to enter into a contract with you to supply electricity, you can rest assured that they will do anything necessary (if anything is necessary) to enable them to meter that supply!eon did say they are fitting second generation meters ,that was the first thing I asked them when I started considering having them fitted . Thanks everybody, I didn't expect this much response but a lot of people will be in the same boat I suppose.
As has been said, the very worst that should really be able to happen (and that theoretically only with a first generation 'smart' meter) is that a smart meter fitted by a previous supply could not be used by them as a 'smart' meter - but that only means that you would have to continue to take 'manual' readings, as you are doing now.
