I had a lot of hell doing mine, old fuse head designed for a 60, had an 80 in. Can't up it to 100 without changing the head. I'm fed by overhead 'low' voltage lines. So the following has to be checked
1) From the LV line on the pole to the cable to the house, tails had to be 25mm or larger
2) Main cable coming into the house had to be substantial enough for 100a + distance
3) Fuse Head to Meter - has to be 25mm tails for 100a fuse
4) Meter to Consumer unit - has to be 25mm tails for 100a fuse
5) Preferably an isolator fitted between the meter and the consumer unit
Items 1&2 are checked by the DNO (in my case UKPN)
Item 3 can only be upgraded by your electricity supplier (in my case Octopus)
Item's 3 & 4 can be carried out by your friendly neighbourhood sparky
In my case the power pole looked more like a tree than a pole due to beyond significant levels of ivy, preventing them from checking, it's taken 3 months for it to die back since the line clearing team stripped the lower half of the pole, they're coming on the 18th May to switch the fuse, I started this in January.
I also had the displeasure of finding out some idiot had rounded off the screw in the fuse holder preventing Octopus from changing the tails that required UKPN to come out and live change the fuse holder to a new one, something they would need to do when they did the 100 anyway and IMO something they should have just done the first visit would have taken them 10 minutes and saved both them an Octopus a 2nd visit.
Earthing is the next battle, thankfully my house was built by a factory and it was deemed PME was the best route rather than earth rods. Does mean my install cost included £120 for a MAT-E box, that annoyingly hums and has a flashy light - not ideal on my landing.
The EO charger can throttle based on a CT Clamp, my guy didn't install one as I was getting a 100a fuse, he also didn't connect it up properly so it is currently working as a dumb charger and Octopus are having trouble getting Charged EV out to resolve it. I have it on good authority that Octopus will no longer be using Charged EV as they're a bunch of clowns. I found out who the installer was too close to the March deadline to actually do anything about it.
