@Andy+Herbert while Sky are by no means perfect but most of the issues you report are down to the way ISPs and Openreach are required to communicate. Ofcom require all communications between Openreach who are the monopoly network supplier owned by BT to go through a single system so no isp have an advantage which is great in theory but frequently causes these issues in practice.
Openreach assign a number of jobs to each engineer whether they are their direct employees or sub-contractors for each am or pm period but where a job over runs the later jobs get dropped. This means Openreach have to pay compensation to Sky who pass it on to you see Customer Auto-Compensation | Sky Help | Sky.com but the job goes back in the system to have a new appointment and is not prioritised. I wont bore you with details of my own installation saga but this happened to me twice with third time lucky.
Last summer I was in a group of Forum Superusers invited to Sky's largest Customer Support operation in Livingston and we met the agents and their managers doing this work. They are only too aware of the lousy service their customers often get. We were told Sky are training their own engineers to do the final install even doing the overhead work from the pole. This will give Sky far greater control over the whole process but as yet many jobs are still with Openreach.
