Light switch relocation (fair price or DIY?) (Ed.)

[flameport]

, or is this totally doable?

It can be done, but not in the way you might expect.

Cables can't be left in the walls where the old switches are, so the most likely method would be to:
cut a section of coving out directly above the existing switch
cut away plaster or whatever there to locate the existing cable
remove the cable
join to a new length using a suitable permanent method (not screw terminals)
run that cable either above the ceiling or behind the coving to a position above the new light switch
chase the wall vertically down to the new switch
install a box in the wall
repair the walls
connect and test the new switch
replace the coving sections
fill & redecorate.

Repeat for the other room.

The electrics were completely redone when the previous owners extended the house about 5 years ago.

That should mean a consumer unit that's recent and suitable but that would need to be confirmed before anything else.

Quinetic....wireless....maybe=less headache?

I have one controlling 2 outside lights that works without problems.

Thanks for all this. There's a lot that I don't know and will only appreciate when someone draws my attention to it.

So, I'm away from home so can't photograph, but I'm pretty sure my circuit breaker has rcd protection, though I'll check when I can. The electrics were completely redone when the previous owners extended the house about 5 years ago.

As to why I want to move them, it's that there in inconvenient locations. One is in the hallway when it controls the light for the dining room (not too far, but a nuisance). The other is smack in the middle of the lounge wall, which is where I'm looking to put a large mirror.

From searching, safe zones seem to be a practice of routing cabling around edges or corners of walls. Presumably so that idiots such as myself won't drill through them when adding large mirrors. Sounds very sensible and I've no idea if the electric works in place have followed this.

You need an Electrician. You are not competent to DIY this.

What a pointlessly condescending comment without offering anything of value.

Where is the explanation as to why it's beyond my ability? Which you somehow feel confident to judge without knowing me. Others have already commented on the challenges, so what value does your comment add?

Also, I'm pretty sure I said I'd be getting an electrician regardless of any involvement.

Thanks for the detailed comment.

I've mentioned before, but I'm not looking to do the whole job myself. I wouldn't trust myself not to start an electrical fire if I started to play with the wiring. This has given me a good idea of what's involved if I were to prep the walls ready for a skilled electrician to come and do the wiring side of things, just leaving the plastering for me to finish.

Others have said that some electricians might not be keen on taking over from prep I've done myself, so I'll just have to feel things out there
