Hi,

Wanting to have an extra double socket and a single socket installed in my kitchen.

Getting mixed answers whether I can take a spur of another spur, I have attached a picture of what is required. One socket if for a dishwashers the other is for above worktops.

Advice would be appreciated?

Why don't you turn it into a ring final circuit and dispense with the spur? After all it is a kitchen and you will need more sockets than that. I am not too sure about the wisdon of sockets low down and water things by them regs aside.
 
And you need to be certain that any point that you intend to take a spur from is actually part of a ring and not a spur already. Spurring off spurs is a no - particularly in a kitchen where the loading on sockets will be higher than anywhere else in a house. And please be careful if intending to chase down where the red vertical line is shown, you may well hit the cooker cable between the switch and outlet plate as I've often seen this link installed diagonally.
 
Are you certain that the starting point is a spur and not a ring? Its impossible for people to advise from those photos sorry.

It could be the case that the start point single was originally a double on the ring and they swapped it to a single socket along with a FSU (also now on the ring) to isolate the socket below it for a washing machine etc.

On the back of the FSU are there 1 or 2 cables in the IN/SUPPLY terminal?

Im only a DIY'er but i would be very careful adding what you have suggested as you might find when you chase the wall out that you cut straight through the cooker cable in the wall unless youre removing it anyway?

Edit - Sorry Dave, just seen you mention the cooker cable already! Mine was diagonal in the wall between cooker switch and wall outlet plate, found it when i ripped it all out for my 1st fix rewire ready for the pro's coming in to 2nd fix.

I guess far too many so called electricians just go out and put things together and if it works then ask for the cheque. no money back or guarantee when it goes wrong.
the thing i have always thought was good advice when dealing with any tradesman is ask them to explain why they are doing it the way they have decided and what regulation or rule makes it permissible.
There are some useful explanations of what people have said in the big yellow book of fun known as the 17th edition. might help the OP if he has a copy. appendix 15 - pages 453 and 454.
I was trying to explain the very same issue on a quote recently,as the customer wanted me to join a couple of sockets onto a ring, so out came the big book.
 
On face value only from the photo's shown the wiring is twin & earth installed in metal conduit (in part maybe) it looks like a ring final circuit, how ever this will need to be proven by testing. There looks like there is a red live cable come out of the L.H.S. single socket. You maybe able to take the link between the socket and D.P switch out and extend the ring.
 
Sorry if I'm being thick but not totally clear, are you saying you just want to change the existing high level single socket to a double now and leave the DP switch and single as arranged at the moment ?

The rcd spur being fitted is probably because there wasn't rcd protection of that supply.
