Returning first pcp

[Notsure101]

Apologies for what is probably a lame question.

I'm shortly due to return my first car on pcp (3 years). And one of the items the company wants is the service history, is this as simple as the stamped service book or would they be after further paperwork or evidence?

Thanks

Stamped service book. No need to give them receipts unless you wanted too.
