Are UK PC part prices just crazy compared to US/Canada or is it just PC Part Picker?

So I was watching the PS5 Pro killer video and thought I'd add the parts to PC Part Picker at the same time, to see if it's actually a viable build for me (I'm hoping to build my first PC soon)

I'm aware that all of these parts are brand new, but even without a case it's about £170 over the PS5 Pro price. Am I doing it wrong, or is it just really expensive to build a PC on this rainsodden island?
