I contacted UKPN to ask if my fuse could be upgraded from 60A. I'm having an EV charger so my electrician has recommended 80 or 100. I've just received this in an email. 'In your area our network can only guarantee 60A per connection'. I've been asked to send a photo of my cutout and CU for one of their technicians to comment on. I'm in South London. EV chargers are sprouting up everywhere so are they starting to restrict power usage? My fitter said that he can throttle most EV chargers to 16A if needed.
