£2000 mains conditioning unit fails to protect electrical equipment.

Not however scientifically educated I suspect. It really does make a difference to how you see the world. An artistic or classical education does not prepare you for turning screws the right way, changing tyres or not being over-charged by the man who unblocks your sink.  It also does not seem to prepare people for spotting con-artists generally.

The description is that of a ferrite ring choke and sockets with sprung contacts I'd hope there are some X and Y capacitors either.

Ferrite ring choke cores are not that expensive if they hand wind the mains lead through them, and actually ready wound ones exist that you can solder to and are what we use inside apparatus for such things.

Of the £2 grand, a mere £1,950 of it should be profit !! 

This is  far more reasonable, and has a little window to show off the wiring inside..

example of a good one from amazon.
