I've had an OR ONT in the loft for a year, and various switches/routers there for many years.

The loft is both insulated and ventilated and while it gets warm in the summer, it is only borderline on the very hottest days of the year. It's certainly well short of a normal indoor temperature in hot-climate countries.

No concerns with reliability or temperature of equipment.

Same here. ONT in loft.

MJ Quinn engineer was perfectly happy to site it there.. alongside the CSP which he also fitted in the loft

I supplied a draw rope in metal conduit from fibre entry point, we pulled the fibre together with him outside and me inside.

Zero issues in the (almost) 2 years it's been installed up there.

My CSP is loft installed to and originally teh CSP to ONT was about 200mm! But left enough slack for me to move it later about 1m away.

My duct is 20mm plastic. Picks up on the soffit, runs along that koft wall for about 5-6 m, before a swept bend to pass through a 300mm wall into te other loft, whenre it runs along a short way then bends up and into a standard 85mm backbox.

Make sure that any bends are swept and not elbows which makes pulling way easier.

It depends on the engineer but a loft ladder would likely be a no-no for an Openreach employee. I'm sure yours is fine but they know what the rules are, and if your ladder collapses and gives them an injury that means they can't work any more then Openreach won't pay out.

You may find that a subcontractor is more likely to agree to this plan, or alternatively go with the conduit plan and bring the outside fibre cable directly into your cupboard where they can fit the CSP.

I wouldn't have any concerns about temperatures.

The cupboard is deep inside the house, it would be an internal run of about 7 or 8 metres through the loft.
I wouldn't have thought that amount of external fibre is permitted to be run indoors (even in conduit ?) Fire and smoke concerns ?

I think the PVC conduit would burn better than the cable so it's sort of a moot point. Depends how much the installer cares as to whether you'd get them to go along with it, but I think it's more likely than them going into a loft.

It's a very workable option, depends what mood etc the installer is in on the day !

It's only a Tenner's worth of Screwfix expenditure to run the conduit in speculatively.
If it ends up being the outdoor option, then I'll prepare for that too. I'll fix a bit of 12x12mm trunking on the 'inside' lip of my uPVC soffits, coz I don't particularly want the black fibre cable tacked to the outside face my nice white uPVC.

(It's a bungalow BTW, not a house)

My ladder is a very substantial, professionally-fitted item. Neither the OpenReach lady fitting VDSL some years ago, nor last year's CityFibre crew for Fibre, had any issues.

WRONG.

We all know Openreach engineer will not going up the loft for their own safety. So, it a big NO.

Why do you keep posting false information?

Openreach WILL install in lofts - as I and other know full well.
