Does OVO have plans to offer a 3 Phase smart meter for supplies larger than "100A per phase” connections (CT-type meters), and “vector sum” compliant?
Updated on 06/05/25 by Abby_OVO
I notice that there has been news earlier this month of the first 3-phase SMETS2 meter install in the country by Smart Metering Services (SMS) on behalf of their client, Good Energy for a private domestic customer in Gloucestershire.
This “UK first” appears to have been installed using a “direct current” type three-phase Aclara SGM1400 meter, suitable for “smaller” three-phase (sub 100A per phase) supplies found in larger domestic and small commercial installs….presumably the sort of customers that OVO previously could not provide SMETS2 smart meters to.
Are there any plans for OVO to follow suit?
Do OVO offer 3 phase smart meters?
3 phase (aka polyphase) installations in domestic properties are few and far between, so it's a minority of meter engineers across the country that have the skills required to complete these installations. There are also some technical challenges in making sure your job is allocated to an engineer with these skills but we are just as keen as you are to have Smart available for these sites ASAP, so if you would like to take part in this beta stage release, please consider the steps below:
From the start of May 2023, if you have a single rate 3 phase meter (i.e. not Economy 7 / 2-rate etc.) we would encourage you to book a smart meter appointment as normal online or over the phone on 0330 303 5063. (Please do not attempt to book sooner than May unless you have been contacted.)
This will then go through to a specialist team who will validate that it is single rate job and that an 3 phase engineer is available in your region. If this is the case, they will re-book your appointment with the right engineer. (So please bear in mind your appointment date/time will likely change, but we'll try to keep it the same where possible.)
Unfortunately, if you have a 2-rate meter or are not in an area covered by our current crop of 3 phase skilled engineers, you will need to continue with your heritage meter. We know this will be frustrating, so we are sorry about that, we are working to expand our coverage and by you flagging your interest to us, you are helping us shape where and when that coverage develops. - thank you!
