The new additions are on the top of the wiring on the telegraph poles around our property not the new development. They were neat and tidy and now there is a mass bundle on each top going to these little black blocks, they seem to run into the blocks then there is nothing going out of them. Look a right mess.
Generally, the copper at the top of a telegraph pole is terminated in a "DP" (distribution point). They take in a 10-way (or more) cable from the street duct, and separate out into separate cables per property.
Here is a relatively new one:
Fairly new copper DP. Old ones can be other shapes (mine is a round one, looking like a fire bell).
Here is a copper DP, with a fibre manifold being added next to it:
Copper and fibre.
Are you seeing anything like these?
Sometimes a pole doesn't just exist for the final drop into homes, but is also a route for the distribution cable - which would then run from pole to pole to pole.
In this case, you will see thicker cables running pole-pole, and thinner cables to each house. Sometimes the thicker cable needs to have a joint .... which can add to the mess.
He said that the green cabinet 750m away was saturated, no more slots, but BT aren't prepared to put in a new cabinet so they are "splitting" our connections to make room for the new houses.
Maybe unrelated but I noticed today an engineer called round a neighbours who was not in. Then he got his ladders out and was fiddling around with the wire that goes from telegraph pole to neighbours house at house-end. It seems like they are modifying our wires somehow.
Whatever they are doing, it seems to be something relatively unusual and non-standard. Some photos will definitely help, though you will have to load them up to a separate website.
I use

He also said the cabinet is 750m away and so we should get full speed.
FWIW at my old address the cabinet was 1.3km away and I got almost twice the upload speed.
The problem is that distance is not the only aspect that matters - the thickness matters just as much too, as does the amount of interference from neighbouring lines.
The majority of BT's lines are 0.5mm copper. On this stuff, you can get 80/20 speeds out to around 350-400m without interference; speeds can drop below this with a lot of take-up. At 750m, I wouldn't expect more than 40-50Mbps at best.
Some of BT's lines can be thinner - 0.4mm. On this, top speeds are likely to only get 200-250m.
Some of BT's lines are thicker - 0.6mm and 0.9mm. In the case of 0.9mm stuff, the top speeds could go 2-3x the distance: 600-900m
