No, you do not need to have a Smart Meter if you join OVO.
Some people don't want them because they are getting a better deal on exporting solar-generated power back to the grid on their existing meter. And others are waiting until the next generation of SM's is available, which won't be until Nov'18 at the earliest.
There's still 2 years to go until the Government's deadline by which we should all have a SM. And no one has yet decided what happens if a customer still refuses.
Simply sign up for OVO today. You will get a reminder to say you can have a SM... which you can ignore.
