Cost of an ecomnomy 7 meter change

Hi, I am planning to switch my supplier and am considering Bulb.

I have a Nissan Leaf EV and will be charging it regularly at night .

I do have a Eco 7 meter ( I have a smart meter ) .

Will I need to switch to an Eco 7 meter and how much will it cost ?

@Bulber If you already have a eco7 meter then we do not need to switch it out!
