Hi @MrsH and welcome to the OVO online community,
Great to see our community volunteer, @Blastoise186 - on hand as ever to help ease your smart meter concerns!
In answer to your meter certification question, the details of your meter’s expiry date are held by industry who’ll advise us when it’s time to get your meter replaced. Whilst it varies meter to meter, the shelf-life is usually between 10 and 40 years. For more details on the meter certification process check out this in-depth guide:
@Blastoise186 has also got it spot on in terms of the future potential of a Time-Of-Use tariff, whilst the smart meter technology does make this technically possible, it’s by no means imminent and would, like all energy plans, be offered as one of many tariff options. We’ve appreciate this can be a common hesitation so have covered this (and other smart meter concerns) over here:
I’m hoping these guides help - please do let us know if there’s any aspects of the smart meter upgrade process that still worry you. We’re keen to understand these concerns so we can better help all our members when facing this new technology adoption.
