Spur help

[joe68]

Hi all I need to put a new double socket in utility room for a fridge freezer.
The nearest socket I have to the utility room is in the dinning room just opposite the same side wall.
I was planning to spur of that single plug socket, which has 2 wires in this socket.
Will I be a able spur another 2.5mm cable out into a new double socket into the utility room or will need to spur from the single socket into a switched fcu then new wall socket. At the moment I've got fridge/freezer on a 13amp extension lead don't know if extension lead is good enough for the appliance

I also wanted to put a light in garage
Only have a wall socket which has one cable going out from this into a fcu which operates the garage door.
Will I be able to run another 2.5mm cable from the same socket into another switched 3 amp fcu and come out with a 1mm cable into a ceiling rose light

Welcome to the forum...

To give accurate answers we need to know the current protective devices for the circuit, and if its a radial or ring composition..
As you cannot assume what the existing circuit arrangements are just by the number of cables in a socket..

e.g.
A socket with one cable may be the last point in a radial circuit...
Or it may also be a socket spurred off a ring final.

A socket with two cables may be part of a ring final...
Or it may also be a mid-way accessory part way along a radial circuit.

A socket with three cables in may be a branching point on a radial circuit, (one supply in, with two feeds out)...
Or it may also be a branching point for a spur off a ring final, (two ring supplies in, with one feed out).

Basically a bit of continuity testing on the dead circuit is needed to verify its composition and thus what is the best method to extend / amend the circuit.
