it shows Single Dwelling Unit Residential UG congested duct.
Does that help to know whether there is considerable dig work or not?
My takeaway on that is that there is an existing wayleave in place so the PTD should be a formality to expand capacity in the ducting, I would suggest you stick with an FTTP order and as suggested by Zarjaz and Taras get yourself a temporary 4G router.
PS - If there has been no comment from Sky about excessive charges then I don't think it would be a massive job as Sky do like passing on the full excess charges on these sorts of jobs.
