The current double socket is un-switched and only ever gets a hoover or

but using proper wiring instead of a 4-gang.

How safe or not is it to run a spur from this spur?

In the situation you describe it would remain safe. However can you
guarantee that the situation will never change in the future (perhaps
after you sell the house etc)?

My thinking is that it
might bridge the connection and not even work, not to mention be dangerous.
Comments? Options?

The correct way to run more than one single or double socket on a spur
is to make it a fused spur. You may be able to achieve this by adding a
FCU close to the existing double socket, and wiring such that the double
socket and the new socket are both downstream of the fuse.

You will need to check that the existing spur really is a spur from a
ring circuit (i.e. not a radial)[1] and also that if it is a spur it is
the first accessory on it (i.e. check that someone else has not
"extended" a spur already!)


[1] if it were a radial with appropriate protection then you could
extend it with no further difficulty.
