Yes the one the council used last Thursday was on a large truck and
powered by a powerful engine, and was extremely noisy.

Yeah, that’s how they do it here when removing trees.
With the chips going into a massive bin on the truck.
Tho they don’t actually chip the main trunk itself.

If you have a lot to do hiring one of those for a couple of hours might be
the best approach,

Not clear if they rent those out and you'd
need a truck license to drive it anyway.

but give your neighbours ear plugs first..

They're not that bad, but you can certainly hear it streets away.

I had a Performance Power one eventually gave it away, it did OK on
branches up to 30mm but seemed to struggle to chip up green stalks and
leaves the most frustrating thing about it was the time it took made even
longer by having to unclog it every so often. In the end it was quicker
and easier to cut up branches into lengths easily transportable in the car
and take to the recycling facility.
