The white cable sure is four pair Cat 5E
Who knows what that's for... Magic?
The black cable is stancard CW1308 multi pair cable, used by OR in multi line installations.
Whilst it's not neccessary to have that many pairs for one phone line it adds redundancy in case you want more than one line or needs a pair swap in future. Usually OR would only use this cable for the feed from a DP underground to a DP in a block of flats. Still perfectly fine for use with one line.
So all in, pretty standard fare.
FWIW I have CAT5 running between the DP down in the basement and my NTE5 in my hallway, they just used bog standard solid core UTP cat 5, but hey, it works fine for me, manages a 80 meg sync rate so whatever...
EDIT: Congrats on your house purchase!
EDIT2: Waaaaaaaaaaait. Here's a guess:
The black cable feeds from an underground openreach DP
The white cable feeds from inside the property to the builder installed extension sockets
Chances are Openreach would run those two cables to the inside of the property right there and put an NTE5 in with the black cable connected to the A&B points on the rear and the CAT 5 to the 2, 3, 5 points on the faceplate.
Anyone agree? Or perhaps an XTE outside?

BT / Openreach - You've finally done well. Very well indeed.
