if that's all there is, you might not get charged anything at all, or if you do, it won't be much.
I sent back a Skoda Citigo just over a year ago which was on a PCP with VW finance (not sure what difference leasing/different companies makes).
It was pretty shabby - there were two scuffs on the back bumper that I would describe as quite bad as I backed it into the corner of a brick wall, which made a long deep gouge in the paint, also a bus brushed past the corner of the bumper, and also there were a couple of door chips and one on the wing mirror and like you, I was worried about charges.
Just before it went back, a man from an auction company came to assess the car, took a load of photos, made notes, connected his ipad to a printer in the boot of his car and handed me a bill for about £80. He said most of the damage fell into 'fair wear and tear or would polish out'.
I was stunned and just about managed not to kiss him
.
Getting the chips done by Chipsaway before it goes back is one option, but I would caution against this, as I got a quote for mine and it was nearly £400, and I'm glad I didn't go for it, because the assessor said that a lot of the charges they make are to redo repairs done by the Chipsaway type people. I don't know if this depends on the type of damage or the paint colour (mine was metallic green, flat white might be different, although there are many shades of white, as I learnt when trying to buy a new panel for a uPVC door).
