Quite an easy exercise to do. One I did before Christmas. You need to assess if you need to pay for an outdoor aerial to receive all Freeview stations OK. The. Add the cost of a set up box to record any programmes/series you want to see later. Then add costs of any streaming services eg Amazon Prime, Netflix etc. Plus broadband costs and landline yearly costs.
I added this up spreading the cost of equipment needed over, say 5 years to get an average yearly budget. I compared this with receiving a compatible bungle from VM. Then you have to factor in whether you want to bother with the upheaval (yes). Or, perhaps change service provider every year or so to get the new customer discount.
Pretty easy to do. The problem asking others for their opinions on a forum is that only you know what you want/prepared to do etc.
My research was positive.....but I then got a healthy discount (20 years with NTL/VM) . So, will do the same exercise next year to assess if savings are worth the upheaval.
