Personally, I disapprove of calling these loyalty discounts. They are, in most cases, disloyalty discounts.
I have advocated before a true loyalty scheme which rewards true loyalty by giving automatic discounts for continuous custom, say after 5, 10 and 15 years.
I would also scrap Retentions, Outbound Retentions and New Customer deals.
A fixed price list for all would be required too.
The problem is, as has been said many times before, the industry, all suppliers are too engrained in the current new customer discounts / inertia system that there is no way such a change as I advocate could ever occur.
As a Very Insightful Person, I'm here to share my knowledge. I don't work for Virgin Media.
I was paying over 100 for two fully loaded boxes with HD, Sky Movies and Sports and 350mb
I downgraded to 40 pounds a month for one box with HD channels but no Sky movies or Sports and 200mb
I don't miss much of the missing content, or notice any change in internet speed. I used the savings to buy a nice Smart TV which is hooked to internet and between freeview and internet tv gets everything I had before....700 pound a year saving, I can buy a new 50 tv every year if I wanted to.
