Est speeds for VDSL A and B are 21.3 to 11.9 downstream. Something somewhere doesn't add up.

That gives a clue that it might have been BDUK, but good luck with finding out as we have BDUK FTTP but neither BT or BDUK seemed to know at first.

In reply to a post by Thaumaturge:

According to the info there, "cabinet 1" is 150 - 250m from the postcode cluster (crow flies distance)

No, it can't tell you that.

All it tells you is the *postcode* that the cabinet is within: the actual point plotted is the centre of the postcode, that's all. But you can often spot the cab in streetview if you look around.

The postcode given for the cab is not large geographically, only a couple of dozen houses maybe. It's not far away, and the sun is shining (at the moment), so I will walk round and have a look at some point.

There's a mystery here, and I want to get to the bottom of it. If the cab is within even a few hundred metres of where CodeLook says, then I can't see why VDSL performance at the cluster should be as poor as quoted on the BTW checker, unless the cable routing is bizarre.

A search on postcode alone will pick up on the location of the postcode 'centroid' which is supposed to be in the centre of all the properties in the postcode, it will not be the location of the cabinet.

So I walked round the whole postcode, twice (addresses checked on the PO postcode finder) and there is no sign of a cabinet anywhere. If that area is instead served by a cable coming up the hill from the nearby small town, I can understand why their VDSL performance is so poor.

On the way there and back I checked other cabinets. The cabinet I'm on is not shown in the correct postcode on the CodeLook site. There are other cabinets shown on the map which aren't there, and cabinets which do exist that are not on the map. So at least in this area, the CodeLook site does not seem reliable regarding cabinet location info.

Any property with no access to SuperFast (30Mb/s) would have been eligible for BDUK funding.
There was limited BDUK funds and they always targeted the cheapest to cover premises.

It's possible that these properties are all under 30Mb/s on the Wholesale checker meaning they are all eligible for funding.
It matters not where the cabinet is located. Sometimes lines go in the opposite direction and halfway round the village before getting to a property.

This cluster of properties may have been the cheapest in the village to provide FTTP to therefore the only properties eligible for the limited BDUK funds available.

Openreach also do some rural FTTP as part of their commercial rollout, paid for by their own funds.
If they surveyed your village and this cluster fell within a deployment threshold and everywhere else didn't then that would also explain it.

As already mentioned this could have been a CFP arranged by that part of the village.
This won't be documented anywhere and the only way to find out would be to ask someone who was involved in arranging the CFP.

There's a high chance you will never find out why these properties have FTTP.
