Replacing spur one gang socket for two gang

Hi all,

I have a single surface mounted socket in a cupboard which our freezer is plugged into. We don't have any sockets in our hall which the cupboard is off so I thought it might be useful to change the one gang socket for a two gang, again surface mounted to keep it simple.

Its on our socket ring main and must be a spur as there is only one cable to it not loop in and out. In theory I think all I need to do is remove the old one gang socket and screw on a two gang box in its place, I would just use the existing supply to the old socket. Suitable checks need to be done prior to just swapping the socket Willy Nilly, an Electrician will be able to check this for you.

Assuming I'm right on the above? Seems like a simple job. Any regulations I should be worried about here? Given I'm literally just replacing the surface box and not changing any wiring? Is this notifiable?

Thanks for the advice

You are not installing a new circuit so it's not notifiable.
Is the circuit RCD protected?

The cable from the ring main goes to a fused switch.

Going back to what Pete999 & Spoon said, assuming it is a spur off the ring main is the fact that it is supplying a light and a socket still classed as a single spur? And how do I determine that its not a spur off a spur? In theory it shouldn't be as if the work was done properly then no one should have done that in the first place? I realize you should never assume.

So in your first paragraph above you are only assuming it wires to the RFC.



See where this fused switch wires back to.
You can test the circuit to determine what type of circuit it is.

Hmm I can't track the incoming wire as it disappears into the wall, would need to pull up floor boards etc to track it. I do know that when I switch off the MCB to the ring main the light and socket are cut off but that doesn't answer if its a spur off a spur.

Ok so I've had a closer look at this and noticed something but don't think it affects me converting one gang to two gang. The cable from the ring main goes to a fused switch. From the switch there is a cable out to the socket and a cable out to the ceiling light in the cupboard. The cables terminate at these loads and do not go elsewhere.

The fused switch only operates the light as expected and does not cut power to the socket.
