Solar PV and Smart Meter

Options
Short question, are you forced to have a Smart Meter installed if you have a new Solar PV system installed?


Of course, depending on the answers, more questions will follow;-)

    It depends.
    If you've already got a relatively modern electronic but non-smart meter, you can probably keep it.
    If you've got a "spinning disc" electromechanical meter, it will probably need replacing and the only replacement you'll get is a smart meter.
    If you want to be paid for export you'll have to get a smart meter.

    We've just had a solar panel installation with a "spinning disc" meter. A replacement wasn't mentioned.

    I think there are two types of spinning disc; one that can spin backwards and one that can’t.

    Thanks for all your replies.

    The house is new, still underconstruction I guess. Whereas I recognise that the supplier of the gas and elect, probably Octopus, would want to install smart meters and I would have a small battle to resist the said Smart meter which I understand that you can still do. Could I still resist if having Solar installed?

    Note; I don't think they would install a Smart meter for the gas supply since the meter box is in the ground!

    Thanks

    your installer should inform your supplier and then  its  up to them . i would of thought a new house would have a smart meter fitted as normal  unless your meter is only a temporary fitted .a new  series 2 meter should not cause you any problems but if  your disc is spinning backwards its not your problems. i had 2 years of negative bills before they sorted mine out

    A brand-new house will have smart meters fitted.

    Sorry guys' its my own build. I built the house next door (2018) for my sister and managed to resist the installation of smart meters, I was hopeful of resisting again (although I not sure why, perhaps I've got to that age where you just hate change).

    I also understand that it is not obligory for you to have a smart meter installed;

      A web search, just now
                Do new build houses have to have smart meters?
                No. Smart meters are not compulsory. However, you may find that some suppliers will only offer
                you a competitive tariff on condition that you have a smart meter fitted

    but, is there a reason not to have a Smart meter1

    I already had smart meter before my solar panels were installed.  Be interesting to see how far they reduce usage.
    Paid off the last of my unsecured debts in 2016. Then saved up and bought a property. Current aim is to pay off my mortgage as early as possible. Currently over paying every month. Mortgage due to be paid off in 2036 hoping to get it paid off much earlier. Set up my own bespoke spreadsheet to manage my money.
