The service you experience with Prime definitely depends on where in the UK you live, or rather where the item is going.
I live in a city centre, within 50 miles of an Amazon distribution centre, and it often offers me same day delivery. Like, order at 3am, items arrive at 8pm.
But if I change it to my parents' address (more remote but still in civilisation), it takes them 1-2 days to deliver.

They were just trying to batch process ;)
Recently ordered a keyboard in UK to be delivered to Spain. Despite being in stock it stayed in 'preparing to dispatch' for a week and I couldn't cancel.
In frustration I ordered another one thinking I could just refuse to accept delivery of whichever didn't arrive first and get a refund.
Sure enough, that time I left the office for half an hour I returned to find two packages on my desk waiting for me :)
