I have a BT engineer coming tomorrow to install our BT line and ONT, where do people recommend installing the main fibre line?
I don't think there's a simple answer to that, other than somewhere with power.
Mine was overhead, so it was largely decided by where he could tie it to the building - he only really had one choice due to path being blocked by a lamp post one side, and porch blocking ladder access the other.
In the end, my consumer service point went out the way - in the corner by the ground with a built-in cupboard with power on the other side, which was the perfect location for the ONT. But I chose that knowing I'd route it back to where I originally wanted it in the garage with Ethernet which goes back up the drain pipe where the main fibre comes down and into the loft before going back to the network cab in the garage.
That said, he was willing to run the fibre to the garage, but it would have run a fairly thick back cable across the width of the property, ~50mm off the ground and it would have looked aweful.
I ended up with the ONT not quite where I like it, but the installation is much, much tidier than running fibre all over the place and the end result was the same.
If I was your average consumer, I'd have just got him to put it in the easiest place that was suitable for a router.
