Wall-mounting a TV in the best way

[pirate]

Good evening all!
I have this job ahead of me, and sadly it's not on a nice clean plasterboard cavity wall, but on a thick-plastered brick wall in a Victorian flat.
Now, I have done some research into this, but quite frankly I would rather have some of you experienced folks point me at the best way to achieve this.
To give you the full picture (did you see what I did there?) the TV will be mounted above a mock fireplace which I have just installed, and which is currently removable, until I have finished everything and have done all the filling etc. Therefore, the vertical distance from the back of the TV to the top of the fireplace is only about 1 foot, or less...below the mantlepiece the cable can exit into the free space behind, and will then be routed to one side, above the skirting, via a drilled hole in the side of the fireplace, a bit of trunking, to the double socket 2 feet away.
The plaster is about 1.5 inches thick. Being honest, would you just raggle it, stick in some trunking, and plaster over?
I know...not best practice, but surely it's obvious there's a cable or two under there? I would label the replastered area. I had to cut the telephone cable when fitting the fireplace, and join it with some new stuff...different colours...put a wee label in the socket for the next guy, and although only 2 wires were in use, I connected 4 for possible future use (Ok, I lied, that was just to help me when I have to do some more work and can't remember what I did!)
Right, buried cables, less than 50mm, but bl**dy obvious...do I protect it?
Any suggestions gratefully received...and brickbats too! The customer is not fussy, but is a VIP!

...and it is what the customer wants!
not dangerous
not against regulations
not contagious (like gravel, for instance...those of you who are young won't get that one!)
not unsightly
not intrusive

not my taste though, either

Dave OCD, it may be 1mm off, but it's a sliding wall mount, so I will check it next week, to the mm, and rectify it ( in the non-electrical sense) as it is easy to move the TV right to left and vice versa, plus some tilt and levelling...
I thought it was bang -on centreline, but with one eye to work with...not a patch on you guys! Oh...patch! did you see what I did there? Lol!
As Mrs Van Gogh said "The trouble with you Vincent...it goes in one ear..."
As Mrs Gordon said " Do that one more time Flash, and I'm gonna wipe the floor with you!"
and for those of you who tutted...I didn't Wago the back box...Lol!
I did fly-lead it though.

Hey I was just kidding mate, looks spot on to me.

Phoned client to get her to check, so paranoid was I!
Loved the response...and we've all done it...
" maybe an 8th of an inch and...1 mm?"

With a downward tilt a wall tv is absolutely fine.

As for the power line adapters, they serve a purpose, whether liked or not, however the Virgin engineer told me they cause issues with their internet in the house, once removed mine has worked fine since.

The purpose they serve can be better served with CAT6 cable.
Also causing interference is illegal.

Impact Mounts was made for RVs, but it looks excellent on my bedroom ceiling. It rotates as well as deploys and retracts. It's quite easy to store it folded on the ceiling by just pushing it all the way up. With one more push, it will hang down for viewing. It includes 5 holes in the base plates for screw connection to the ceiling.

Only comment in case others don't know, the Humax Freesat box needs two satellite cables from the LNB on the dish to enable watching one channel whilst recording another, even recording two others if far enough apart in the sent packet from the satellite.
