I've put in a load of matt stainless steel sockets in my house - I think
they are these ones http://tinyurl.com/g2nzc.

Problem is, some of my sockets are mounted in white plastic surface boxes
because some of the walls are wooden.

I want to replace these with satin stainless steel boxes. Does anyone know
where I might be able to find these? I've drawn a blank.

Cheers,
Piers
