Kitchen/cooker/cupboards and getting behind them.

[solidgoldsoddingjanuaryagain]

I admit I might actually know this if I wasn't a housework refusenik but... My house has fitted kitchen cupboards at floor level, with an electric cooker between them. The cupboards are the sort with drawers on top, and there is a gap at the back of the drawers for things to fall down, and go inaccessibly behind the cupboards.
I think that my passport has gone behind the cupboards. What is going to be the easiest thing to do and the least likely to cause damage (rented house)? SHould I pull the cooker out - is this feasible? Or is there some way of removing or moving the vertical boards that are under the cupboard, between it and the floor?

The plinth (the vertical bit between the actual cupboard and the floor) usually does come off, so try to get hold of an edge. It will probably have some kind of clip holding it on.

OTOH are you sure it hasn't fallen down inside the main cupboard? It depends on the construction, but sometimes the drawer, and the gap behind it, are inside the main cupboard.

Definitely not inside the cupboard. There's the back of the cupboard, then when you pull the drawer out and look upwards, there's a definite hole ie the drawer when shut goes right back against the wall and there is a gap about an inch wide for stuff to fall down.
OK when I take the plinth off what are the odds of Giant Killer SPiders being behind it? (wuss emoticon).

TBH I don't usually find spiders behind mine - just lots of dust-bunnies!

I am going to make DS dad do it when he comes round on Sunday (then if he breaks it, it's his fault). Mind you even if the plinth does break, a new plinth will cost less than the £72 a new passport will cost.
