Energy provider and FiT

Our existing energy provider is OVO. We pay 14.5p per kW and feed-in-tariff is registered with them.

Our DNO IS Scottish Power and they won’t fit an Economy 7 meter.

Our contract with OVO is coming to an end, and they want to increase our fee to 15.7p. I was going to shop around, and if I find a new cheaper provider  does anyone know what happens to our FiT payments? Do I need to register again with the new provider?

We have an air source heat pump, so I need the best unit rate we can get.

Also, has anyone heard of or used Social Energy.

I don't believe there is any connection between FIT management and energy supply.

My FIT is with British gas, (who was energy supplier when the solar was installed), but I'm with EDF energy now.  No issues arose when I changed.

FiT can be with anyone.

DNO don't fit meters, your energy supplier does that, so OVO or whoever you go with next are responsible for the meter.

Thanks for the clarification guys.
