Installing new led strip under kitchen counter

Going to be installing some led strip under this customers kitchen counter. They said they would be happy to have a plug in led strip to make it cheaper, similar to the lights they have now under it although, they were questioning whether they wanted a switch for it instead of turning it on/off at the plug.

The easiest way I was thinking was to have a flex plugged into the socket and then run into the cupboard above and into a box which will have a Quentinic receiver in and then out of it into a led driver which then feeds the led strip. Only thing is, it will take up space in the cupboard.

What do you guys think
