first switch power off at mains and double check wires with tester !!
Yep, I forgot to mention that. Also, even if you have an RCD consumer unit which normally protects you from a serious shock, the lighting circuits are sometimes intentionally wired without the RCD. A large part of my working life was on non-domestic live equipment up to silly voltages, I usually handle wires as though they are live whether they are or not.

Thanks for the help and I have another light that I need fitting for the kitchen. ![[Linked Image]](https://preview.ibb.co/kCkaXm/connect.jpg) I'm thinking of using the wires below to connect the new light up. Are these the right connections from the photo yellow/green E, Blue N and the last colour L?

Woah, DD you are right, I just noticed in the first pic that red is only a sleeve over a yellow (switch wire) and that is seemingly connected to live! The second one with presumably white paint over the wires makes no sense either What has gone on here? No doubt a professional close look is needed. In the unusual circumstances of using a switched neutral, the yellow should still have a red sleeve because when the switch is off the neutral side of the device is live because its supply comes through the equipment. In the case of domestic electrics its a complete no-no, even more so on lighting circuits where with the switch off you don't expect to have live in the lampholder eg when changing a bulb or accidentally smashing one. I'm really surprised they permit lighting circuits to be rcd-free in the current regulations, you can see the logic of the problem if a whole lighting circuit goes down, but with it being common that people change bulbs and light-fittings it seems to be contrary to the whole concept of having rcds at all.
