The easiest fix is to have the electric meter swapped for S2 first - that may allow OVO to get the gas working on the same comms hub.

Otherwise, it’ll have to be a hot shoe method. Worth mentioning that this whole process might be a bit easier if you’re willing to move one of the supplies over so that both are with the same supplier. Up to you though

This is what the SMETS1 electricity meter (provided by Scottish Power) looks like.

The Gas Engineer that I had over last week said that she can’t put some sort of a clamp in because the ports are blocked?

Just spoke to Scottish Power as well and they refused to upgrade their SMETS1 meter because it is sending data correctly to their systems.

Because I’m technically a PAYGO customer with OVO and the meter / account is stuck in “credit” (?) mode and have outstanding balance that I can’t pay (OVO aren’t allowing me to pay off this in any way) as a result I can’t switch my gas over to another supplier.

If I was to switch electricity to OVO from SP, what are the chances OVO would upgrade the SMETS1 electricity meter to a SMETS2? Would that then resolve all of my issues? Is it guaranteed that upgrading the SMETS1 to a 2 would resolve the issue?

For completeness’ sake - here’s a picture of the SMETS2 gas meter (supplied by OVO energy):

Probably, but please bear with me. I need to ask backstage.

I think if Scottish Power won’t replace the meter as it’s in communications, the best option might be to switch to OVO. If the meters aren’t communicating with each other OVO will replace the SMETS1 meter @d0notdisturb. When you have communicating meters, the support team will be able to remotely change the meter to pay monthly.
