I can’t speak for the UK but I believe the situation would probably be same as Australia. That is, there are a bunch of different ways to cut chips.
The thicker chips you mentioned are called steak cut chips.
The fries (thin, McDonald style) are called shoestring fries.
Long, not thin but not thick (best reference I have here KFC style, but don’t know if they’re the same in North America), would be known as straight cut chips.
