I’ve ordered a new FCU. Going to get it later on tonight.
That might solve the outside light but the switch should have no affect on the spar socket, depending on how it's wired..

Just to add. I'm presuming:
the FCU is just for the outside light, so would have something like a 5A fuse in it and the light wired to the Load side.
the spar is wired to the Feed side.

The FCU is for the outside light. It had a 13a fuse in when I opened it. I am just out at the moment. But I will check how it’s been wired. That should be the case. Light on the load side and spur on the feed side.

Don't you use Tesco Spoon? I thought Spar closed a while back

Looks like the spur has been taken from the supply side of the FCU.
So changing the fuse will have no effect.
Need to look at the nearest socket, to see if the FCU is spurred from that and check the connections.

So further investigation. Below the FCU is a socket, which I changed about a month ago, with a new faceplate. Upon looking there is T&E in the back, which is old colours, 3 red (live) 3 (black) neutral and 3 twin and earth. Looking at it I would say that it's spurred from that socket to the FCU. Then whoever has added in the new socket for the has then taken a feed from the FCU using new colours to that socket.

But I am going to collect a new FCU, so I will check the connections. There seems to be no loose connections or damage from what I can see visually. This is probably were an MFT would be of use if I had the money.

A decent set of safe isolation kit, a good screwdriver and some experience would be the best option

sounds like you need to learn how to use a multimeter for continuity and voltage
or get someone who knows what they are looking for

I am learning, thanks for pointing that out. If I could afford a multimeter then I would buy one. Money at the moment is not great. It's also the reason why I am trying to learn how to do it myself. Rather than paying someone with the money, I don't have to go sorted, and then I don't learn anything.

The first tool that you need is a voltage indicator and proving unit. Once you have that you can prove that something is safe to work on, but you can also use it to test where you have voltage and where you don't.

In this case the smoking gun is that both the socket that isn't working and the light that maybe isn't working are fed from a socket that you've recently changed so that is probably a good thing to look at in your investigations. Three wires are more difficult to terminate than two and so a bit more care is needed. However, this does pose the question as to whether it is a ring final circuit you're working on as an unfused spur can only supply one accessory.

Right okay. I will start with a Voltage Indicator and Proving Unit. See how much they are. I have got my FCU also. Well it could be a ring final circuit, as all of the sockets downstairs are on one mcb. There is another for the boiler and one for the old immersion heater, that we no longer have. I will check the mcb rating to see if it is a ring.

But that fcu for the light has not been used for a number of years. Its an old alleyway light, that was put in. The additional socket for the tv was added a year ago. All were working okay. I will check the connections for the socket with the new faceplate on, just to see if there are any issues. A bit of sheath in the terminals. The kewtech socket tester did not report any issues and all three lights were green. It is an odd one, for me being new its experience of trial and error and asking questions.
