I've never seen kitchen sockets surface mounted like that before. Seems like a lazy electrician. For such a small run they could have been chased into the wall. No real excuse as they were done before the fitting of the units (looking at how the upstand has been mitred around the trunking). I would just tile the wall areas around them. Not much else you can do but to cut the tiles around the trunking and back boxes. 👍
