Deeper back box for electrical socket

[Schizophonic]

So I have a Knightsbridge fast charge USB and its a bit of a thicccc boy and tried installing over the weekend and its quite cramped behind it and think I need to have a deeper backbox.

How easy is the job to replace the back box?

I have in a newish house (built in 2000) and where the socket is located is on the top floor next to bed room, its currently a 25mm back box I believe and the cables come from the bottom. If I get a deeper backbox I know I'll have to make adjustments but I want to know whats best to get as I've seen there are different types of back boxes from the conventional metal and then the plastic dry wall ones.

Depends on your wall, if you have brick you will need the metal, if plaster, you will need the plastic.

Thanks, I know its plasterboard but I think it will have to be a like for like replacement but deeper backbox.
I only quoted toolstation as I can get a staff discount but then its only pence

My next concern, as I'm messing with live wires I'll off course switch off the mains but I can't do too much harm if i handle the cables with care and use a rubber grommet where the cables would go into the backbox.

toolstation are good, you will need the plastic one, its and easier job than the metal!

I'll look to get that when I'm brave to tackle this (simple job)
Looking online to see how internal walls are built in modern houses



I'm assuming mines very close but will see how the back box is attached to the wall....and also you got me worried the cabling falling into the plasterboard....will secure it. Dont want it falling

Save yourself the time and effort and get a spacer for the socket itself.

Especially given the shelf life of those USB plugs is about 12-18months with the advancements in USB charging being a lot smarter than dumping power down a wire.

If replacing the actual back box is difficult you could just try something like thi s- https://www.amazon.co.uk/Schneider-...rds=plug+socket+spacer&qid=1611654450&sr=8-11

It is what I used when I couldn't replace my backboxes to put USB faceplates on.

I didn't know these existed. I might try this first to see how much more room it gives me to play with. If it works out then I might get more of these usb fast charge plugs around some of the double sockets around the house I might use and do that rather than extended back box. I know I should do it properly but considering the possible work involved, chiselling, filling, sanding and etc - i rather use a extension faceplate which would stick out a few mm but save me from making a hash of it all.
