RTS meter and seperate meter for heat pump - do I need to switch?

Meter board is fine!! 😂 unlikely to be a ACM (engineers will still check when on site).

Nukecad,
thank you for the advice re: documentation. I haven't been issued with any, but will ask for some.

Luke,

I agree that the obsolete meter will need to be replaced at some point, yes - I was trying to find a definitive answer there as to what extent and when this will become a problem for a reprogrammed meter such as this one, but I accept that this is outwith anyone's experience.

The reason I can't sign off on getting it replaced as stands is because I can't find any way to contact someone within Ovo Energy who can appreciate that the meter has been repurposed, so an Economy tariff doesn't fit its current use case, and guarantee that I will retain a separate heating circuit and an appropriate tariff.

Here is the guidance I'm referring to from www.homeenergyscotland.org/RTS-switch-off :

"Your supplier doesn’t have to offer the exact same tariff as before, but the energy regulator says you shouldn't be worse off because of the change.

If you’re worried the new tariff will cost you more, like higher heating or night-time rates, you don’t have to accept it right away. You can raise a complaint with your energy supplier and ask them to review it."

I would sooner reach an agreement of what is appropriate at this stage than proceed to raising a complaint, but I need to be able to have the installation assessed by someone with the capacity to advise on both the technical and financial aspects of the installation. Am I any more likely to be able to achieve this via a live chat, as opposed to email, or here?

Would it help if I resubmitted the main points of my issue as separate questions? That I need a smart meter will indeed be the case, but I need to replace like with like.

I’m afraid that an assessment like that is well beyond what an electricity supplier’s customer service or community forum can undertake - there are just too many variables. If you’re not up to doing the calculations yourself, you may find an experienced electrician or heating engineer who could help.

The big difference between your current system and one managed by a smart meter is that there won’t be a constant lower-priced feed for heating. Charges will be based solely on when electricity is consumed, not what for. You can see the tariffs available on the Plans page. However, having a heat pump and solar PV panels will have to be taken into account and will complicate the assessment significantly. You haven’t mentioned water heating - this can also make a big difference.

Some suppliers - including OVO - have special tariff arrangements for heat pump owners. Eligibility varies a lot, so it would be worth your while to investigate these. 

It could be that other community members will come along with helpful suggestions, but I don’t think I can say more at this stage.
