Ovo have informed me that my gas meter needs replacing and that they can only replace it with a smart meter, they have also stated that it will be necessary to change the electric meter at the same time.

I am extremely reluctant to have a smart meter, my main concerns being their accuracy and the ability of the energy company to charge higher prices at peak usage.  My fixed tariff is coming to an end soon and I feel that Ovo will use it as a condition of renewing with them. It seems I have very little choice.

Also how do they know that my existing meter needs replacing?
