Azzy, do you know just how many chargers Milton Keynes has?
Milton Keynes has made use of every possible grant & then some to have by far the largest number of chargers in the UK. In total there are around 400 chargers in the area.
Even I’ve charged at Milton Keynes Coachway where there’s a bank of 8 rapid Polar chargers & 4 Ionity ultrarapid chargers.

A short drive from there is Chargemaster’s head office where there are two ultra rapid chargers, free of course.
Have a look at ZapMap which shows you what chargers are around – https://www.zap-map.com/live/
