Just reporting back having now had our first bill after switching.
We saved around £200 in the month on electricity. Wasn’t expecting such a big saving. Let’s see if it’s a one off, will keep an eye on it for next couple of months. Maybe the plunge price weekends have helped and I don’t expect those to repeat every month but a very good start anyway.

As mentioned earlier we haven’t really changed any behaviour except not charging the car between 4-7pm.
