That's the expected result.

If a copper line is available then the checker will report the local copper telephone exchange.
If a line has only FTTP available (new builds) the checker will report the Head-End exchange.

The same Head-End exchange will usually serve both addresses in the above example with FTTC and FTTP. I'm not familiar with your area though and it might be right on the exchange boundary.

That is the odd thing ... and if the OP is where I believe he is, then it is 2 miles from the exchange boundary and all the businesses I deal with in that area are connected back to Uxbridge for voice, and data albeit via Denham exchange bulding

Is Uxbridge a GEA Headend exchange? Sounds like GX is.

In reply to a post by MHC:

I might be wrong, but two exchanges serving one relatively small/medium development is not something that normally happens, so unless there is a longer term plan to serve the area from GX which in itself shares the 01753 code with Slough!

I guess the parent-child exchange relationship might be completely different for the BT 21CN IP based network, compared to the old switched telephone network (which could be inferred by dialling codes)?

In reply to a post by Pheasant:

For the OP it scarcely matters as it’s the infrastructure build out / distance from the aggregation node for oD rather than headend exchange that drives the excess construction costs.

I just find the differing exchanges an interesting quirk, rather than an indication of cost.

But hopefully it helps that there is fibre passing the top of my road? - even if it is just that ducts have been cleared relatively recently?

In reply to a post by Pheasant:

Unfortunately the price floor seems for all quotes since 2019 appears to have risen by around £3K from those previously. No one can seem to fathom why.

Because demand is higher than available resources to meet that demand?

There is ducted fibre literally all over London. Knowing what that fibre actually is used for is an entirely different kettle of fish. It could be anything not just FTTP. Don't get your hopes up.

Even if it were fibre serving FTTP then it could be spine fibre which you can't simply tap into. The point of connection for FTTPoD is from the Aggregation Node in Openreach FTTP speak. The surveyor will know where that is and is usually quite happy to oblige if asked at the survey.

There are far fewer exchanges that are the headends for FTTP/FTTC. Something like 5000 copper exchanges in the network, but a small fraction of that are used for FTTP. These are what is known as the GEA Headend exchange.

Is Uxbridge a GEA Headend exchange?

No

Is Uxbridge a GEA Headend exchange?

No

Thanks. Gerrards Cross must clearly be.

What are the neighbouring GEA HE exchanges then?

GX and West Drayton

Thanks again. 👍

there a nuance its the aggregation node that takes you back to the headend , in some smaller exchnagere there might be ethernet back to the local serviing exchnage , this is no not good if the local servicing exchange does not got back to right headend or in some cased even a headend (that is more likely if your exchange is small

"Uxbridge" as the dialling code/area has several physical exchanges connected on the old copper network - Uxbridge, West Drayton, Ruislip and Denham so just surprising especially knowing the route from Denham to GX would be difficult.
