Hawker and Challenger Rate for P1 and P2

[1Bingo]

Given the new year and associated cost of living increase, does anyone out there have a good feel for freelance pilot fees (daily rate) on the following platforms in Europe:

Hawker 800 XP: P1

Challenger 300: P1 and P2

Thanks

If it helps Challenger 604 should be about £600 P1 and £400 P2. Don't forget expenses on top.
