I am moving from single phase to a 3 phase supply.
I currently have a single phase economy 7 meter
DNO work has already been done . 3 phase supply in new location. (single phase left connected in original location)
My current supplier, although initially agreeing to fit a 3 phase meter is currently unable to do so as they use 3rd party engineers who are all currently furloughed. They have suggested a move if I need the work done quickly.
So my questions to you. If I move to ovoenergy….
Can you fit an economy 7 3 phase meter?
Supply is standard 3 * 100 amp input
If so how much?
If so when could you do it?
what tariffs woud be available?
I would need some concrete data as I don’t want to switch supplier again, only to find the job can’t be done.
I’ve seen all the details about 3 phase smart meters, I current do not need a smart meter

There’s some good questions here, but I think I can answer these for you. It also sounds like some of the work has already been done, which may well make such an upgrade a little bit easier.
As far as I’m aware, no supplier is able to fit SMETS2 Three-Phase Smart Meters, so if you did get an upgrade, it would have to be non-smart for the time being. However, a non-smart Economy 7 Three-Phase meter might be possible as it is listed under the On-site Jobs that OVO can do (job cost of £325). You can find details about that and the prices over at
If you were to switch to OVO, you should be able to get access to the same tariffs with a Three-Phase Economy 7 meter as any other customer with a Single-Phase Economy 7 meter. I can’t give you a quote unfortunately, since it would need to be calculated specifically for you. I would recommend going for the Better Energy tariff as it’s the cheapest one OVO offers that doesn’t commit you to a smart meter. You can get this tariff with Economy 7 as well if you’d like to.
As for how long it might take, that’s a good question. If I ignore the time required for the entire switching process to go through (14 days to come on-supply with OVO and up to 6-8 weeks to completely finish the entire process), you should be able to book an appointment for a time and date that would work for you.
If you’d like to go ahead, I’d recommend having a chat with the Support Team by phone and that should give you a chance to double check everything before making a decision.
