Yes.

I take it you don’t have an RTS. OVO are concentrating on RTS customers in Scotland at the moment, because the RTS signal is being switched off permanently next summer. This means that others with non-RTS systems may have to wait a bit to get a new smart meter. The ones they’re fitting can be configured for all manner of complex tariffs, including Economy 10.
