We have finally got a date for a battery only system (We cannot have Solar due to roof structure) and the aim is to keep enough overnight to power the day and necessary EV charging. Its certainly not ideal, but with ASHP we had 2 years ago, the low overnight rate and it being limited to renewables, it really is our only option. One we are lucky enough and happy enough to self fund.
Fed up with nuclear tbh, it feels like an ethical and political football.
