May be best in the long run to run a new supply for the outside light if possible if there is enough room in the dis board Maybe run it in a small size SWA or conduit for protection.

I agree with James if you were to put outside lights on existing lighting circuit all lights could be knocked out with a fault on your lights. At least with seperate circuit house lights would still work.

thanks, there is no space on the board, not sure what to do, what product do you use to seal the hole in the outside wall where cable runs in

Clear Silicone sealant, to fill the hole.

Find somewhere convenient to take power from and use a fused connection unit.. and 3 amp fuse if the loading is ok, otherwise 13amp.
You can get external IP rated FCU's to mount on the outside of a wall and run SWA from there.
Take the power through from behind it from a ring or lighting circuit. Nice and neat.

Run a Fused Switched Spur off the Ring main if you can and then run your light off the load side of the spur. Go for something like a IP rated MK spur good quality one. To seal the hole you could use a foam theres alot of things out there for that.

Hope that helps
