Outside lights via junction boxes

[rayleigh20]

Hi. Currently have one outside light that has an outside switch fed from the boiler fused spur (see photos).
can this be converted using outside junction boxes and conduit so that I can have 3 lights at various positions (see photos).
I naturally understand that this is probably a job for an electrician but just want to know if this is possible and if it would be expensive. Any ideas or diagrams welcomed. Would prefer it done in a way that I could then get it carried on around the whole garden as I can afford it. Am I limited to how many I could have (lights) bearing in mind I will probably use Hue Led lights. Thanks

I'm not a huge fan of conduit outdoors, It's really easy for water to find it's way into the conduit system and start flooding boxes. I'd rather see cables with glands.

Yours seems a pretty sloppy installation with the cable run in a loose and untidy manner with few if-any clips.

In any case the first task is to determine what you have? is it fed from the supply side or the load side of the boiler FCU? is that "switch" on the outside actually a FCU (at first sight it looked like a double switch to me, but looking closer one side looks flatter than the other).

The outside is defo a double switch
