Why not use under cabinet lights that do not need recessing,will save a lot
of work

Maybe they want a sleeker finish or whatever.

I put those lights into the overhanging 'cornice/pelmet' in some new
wardrobes. Using the right hole saw it was a quick job to fit them
recessed.

In fact given that I didn't need to drill access hole for the cables,
nor screw the fittings in as the hole size was just right, it was
probably just as quick (not that surface mounting was an option)
