This is plasterboard or something with a void about an inch back
This is the wall plug
The hole here is actually so big that the wall plug would fall through into the void if I put it back
I can't move the radiator up or down or left or right because it is fixed and even if I knew how to disconnect it I wouldn't want to spill black water everywhere and ruin the carpet, so I am thinking I should use the same holes but get a bigger plug
What about the plastic ones for plasterboard that sort of butterfly out when you fix them in?
Good luck, I hope it works :)
P.S. I've just remembered that you can get a socket screwdriver that works like a spanner / wrench. It has a handle like a wrench, but the end is turned 90 degrees, and holds a screwdriver bit. It's ratcheted, so will fit into a narrow space and still work. It could work for both our situations :)
Oh that would help
So I just put a wall plug in for now, could only reach to do the two at the top and the depth was a bit too long so not ideal (need to do it again with a shorter one) but at least it is done and I can forget about it for now
This is the type of screwdriver:

Apologies for the eBay link, but I can't post pictures to a reply. There are cheaper examples on Amazon, but then you have to deal with Amazon 🤷🏻♂️
Looks great thanks
