Hi, I'm currently wiring my kitchen from scratch, but need a bit of
advice.

The built-in fridge freezer manual states that the plug must always be
easily accessible so that it can be unplugged. I have a brick wall on
the right of the fridge, and a cabinet on the left.

What is the best way to provide a socket, but also have access to the
plug? Would I be able to access it underneath the fridge enclosure?
