Best way to label pipes

Hi All,
I hope you are well.
I am slowly preparing for installation of the combi boiler (I reckon in 2026).
I have an old Baxi Solo 15HE, it works just fine but apparently combi is going to be more efficient.

I have the floor exposed, just need to lift some floorboard here and there to identify which pipes are which.
I would prefer to label them so we know exactly which is which and there is no guesswork down the line.
What do you use to label the pipes?
Thank you
 
Would leave it to the pros as depending on
Boiler locating might not need to be in that position
