i was always told not to ask about salary at a first interview (i suppose this might be your 15th interview).
If you should be on £30k in Aberdeen I would have thought £45k in London was reasonable.
This is based on an approx 50% mark up in law - the only area I know - but your industry might be different (without wanting to incur the wrath of non-London lawyers, I think London lawyers work more hours and so get paid more for that reason, as well as just due to increased cost of living)
