My DNO has recommended I set up a Building Network Operator (BNO) to change one 3 phase meter and 7 submeters to 7 individually supplied meters?

Ok, I’m back!

Just so everyone else knows, this answer has been adapted for @pkt and might not be applicable to all circumstances. Please check with your DNO if you’re unsure!

I’ve just spoken to SSEN’s New Connections Team for you and they’ve been amazingly good, which is not surprising given they’re a DNO.

Firstly, they’d like me to give you these - I have permission from SSEN to release this publicly:

Your electrician will need to install a Riser in order to enable seven/eight new connections to be put in.

Please email SSEN with the following information:

• Details of the Company/Building Owner - such as name, address, phone number and email address
• Locations of supplies including postal addresses for the Landlord Supply and all the flats where ALL supplies including landlord will be located
• Emergency contact info for your electrician - they'll be responsible once the riser is installed as SSEN won’t touch anything from the Riser onwards
• Photos of all existing cables/meters, riser location (where you want it to go!) and all sub-meters
• I’m afraid the existing meters must go - including the existing landlord meter

Oh, and please include all the photos you’ve shown us here on the forum too! SSEN will appreciate it.

In fact, feel free to chuck in links to both of these forum threads into that email as well. I suspect the extra context will probably help them out.

Once SSEN receive that email, they’ll be in touch with the next steps. They will generate the MPANs for you to enable suppliers like OVO to take the supplies on and create the initial accounts.

Hope this helps. If you get stuck, give SSEN a call on 0800 048 3515 if you’re in Scotland or 0800 048 3516 if you’re down south and it’s Option 2 then Option 4.
