Hi, if they are live then either they must be removed or made dead then you can simply plaster over.
However if the wires can't be disconnected there must remain an indication they are there.
A flush metal switch box with a blank plate would comply. but not pretty!
An electrical supplier should have a type known as an architrave box which is less than half standard width, but don't know if blank cover available to fit, (never asked for one)
Removal is not an option Im afraid - so I guess ill have to wire up to some sort blank plate and screw that plate to the wall - meaning Ill ahve two light switch type panels but I think thats the only option.
