I think switching to an EV tariff if you can find one might depend on what you are on now. If you are not on a fixed rate then it should be worthwhile but if you are on a fixed rate deal you would end up at the new higher rate on your domestic power and that might would wipe out the EV saving.I stockpiled electricity by charging my EV today and then submitting a reading once it was full.
We have a regular meter but having a smart one fitted in a few days time. Sadly a lot of the EV tariffs have gone and most advice is to stick where you are rather than switch, but I would still really like to get a dual-rate tariff so we can move as much energy usage to the low tariff as possible.
We are on a fixed rate deal until September next year which I went for despite contrary advice from experts and it worked for us as we are well below the current rate and the new one coming in looks to be about a third higher again.
