Network cable reel

[Zirax]

I need to run a network cable outside, does anyone know of a shop that will just sell a reel of network cable? That way I only need a small hole and then crimp the ends.

checked scan, red, green, and blue

Ideally either black or brown to run up the brickwork outside.

edit:- found some dotted around. The plan is to get a 30m length and then cut off the ends & put new on. Should be long enough
