I haven't met anyone who did an MBA in Durham.Check out the target consultancies and view the MBA Business Schools that they visit.Once you do this you will have your answer. An MBA from Durham will not open doors to consultancies for you so who you are and what you can bring to the table will be of more importance.For example, if you have a GMAT score of 790, have worked with a world leader and have leadership potential in your field then go for it.Consultancies are basically selling consultants services and hours to clients.It is easier to sell a London Business School consultant to a client than a Durham MBA. My opinion, which may well be wrong.
