I am currently in a very similar situation to yours (I actually was 1 month ago), i.e. trying to choose between MSc Economics offers, while not being sure whether to go in banking / institutions (similar to you, preferably in London) or proceeding towards a PhD after the Masters.
I have similar offers in the UK to yours (Bath, Durham, Nottingham, Warwick) and BGSE outside the UK. Got rejected by Cambridge and UCL.
From the UK programmes you've been accepted to, Nottingham's is really the strongest (while not by that much), especially for consulting, as well as its maths & econometrics as a preparation for a PhD, plus in comparison to the other UK universities' fees Notts really is a great offer.
I would, however, really not lose hope on rest of the universities you've applied to. I expect Warwick at least to give you an offer as well. They accepted me and in terms of academic profile I only have a high 2.1 from a mediocre UK university.
For Oxford, LSE and Warwick it really depends on whether you need that funding or not. I mean it's more than 15k compared to Notts.
P.S. Since you don't mind going for a 2 year long Masters, have you thought about BGSE, Bocconi, SSE (not sure about deadlines for the last two). I'd argue that their MSc programmes are better known in the UK than Amsterdam and QEM. Regarding the latter's PhD prospectives - better listen to the guys on the urch forum. The answers you received there really are from people who seem to have researched EU programmes well.
My two cents are - If you receive an offer from any of the UK universities you are waiting for - think carefully if you/your family can afford it or if taking a loan would be worth it - and then go for it. If not, go for Amsterdam or Notts. They seem to offer the best choice both in terms of academic training, as well as in career opportunities.
