As already quoted I would have the ONT on the inside wall of the outside box (CSP) and then run cat5e/6 from the ONT to your router that way any issues with internal cable can be fixed with a temporary cable quickly and you can route this cable which ever way you want (up to 305 metres away from ONT).

Don't think so. 100m max for Cat5e/6 Ethernet - including patch leads.

You mean 305 feet of course.

you can get 2.5 Gigabit over 100 Metres of cat5e cable
but even so as you say the OP could upgrade this easily in the future if the get more speed than this
without having to pay openreach to do it.

Unlikely. Cat5e will normally only support 1Gbps. You might get short distances but no where near 100m at 2.5Gbps

Even that is not quite right ... 100m >>> 328 feet

You are thinking of 305m = 1000 feet (or actually 304.8m)

I need to plan the route in my house for the FTTP installation due in a week or so in the UK. My ISP says wait for the Engineer to come, but that will be too late as I need to clear on the routing and so clear things out of the way.

...

Thank you, Thank you, Thank you! ....to anyone that can give one or more confident answers to the above.

Hi Folks
Thank you for the comprehensive answers. They've helped me a great deal.
The speed isn't an issue, as its currently a max of 1Gb.
Distance isn't an issue, as its a maximum from CSP to ONT of c.11 meters.
My main constrain is power points. The nearest power socket to the CSP / entry point is the above 11 meters away. So - I have the black 20mm conduit that I'll lay (with bends, not corners). The ONT can then go under the stairs, and then the Cat5e can go about 5 or so meters onto the top my kitchen units where I have another power outlet (extension) for the router (which is where the current router provides good coverage as its near the centre of the house).
If anyone is interested, 9m of conduit along with connectors, corners and saddle clips was nearly £40.
Not sure how to close a thread, but hopefully I'm all set for the installer now - fingers crossed!

So there's no (or little) point in the increasing amount of 2.5Gb equipment being marketed because it will work with Cat 5e?

For 2.5 Gbps Cat 6 will normally suffice up to 50-55m.

Wrong.

The 2.5GbaseT standard was designed *specifically* to run at 2.5Gbps over 100m of Cat5e. It's the main reason this standard exists - to make better use of existing wiring plant, without having to replace it with Cat6 or Cat6A.

Real world experience is different though.

A commentary that doesn't seem written by someone who knows what they're talking about, if it was written by a human at all.

Cat5e Ethernet cable is designed to support up to 1 gigabit per second (Gbps) of data transfer speed, making it suitable for most home and small office networks. However, it is not officially rated for 2.5 Gbps.

Cat5e cables use four twisted pairs of copper wires to transmit data, and they are capable of handling frequencies up to 100 MHz. This allows them to support data transmission at up to 1 Gbps over distances of up to 100 meters.

2.5 GbE uses 100 MHz of RF bandwidth. The whole point of 2.5 GBASE-T is that it's compatible with existing 5e cabling. To achieve this it fits in the same RF spectrum with the extra capacity coming from a different coding scheme.

The article reads like poor generative AI work.
