our laminate has lifted in a couple of places any advice?

we have laminate through our lounge diner, and in the entrance hall, where it goes from one room through to another it has lifted and the flooring moves, in these two areas, is it because floor underneath is not level and can those parts just be replaced, had it down 3 years and paid quite alot of money for it,
any help greatly appreciated
cheers

its possible its touching a perimeter and has not room to expand with change of room temperature .if edge trim fitted remove a piece nearest to your problem.if skirting on top of flooring sorry you have a bigger problem.JONN
