Interview for lecturer in UK but no grants, how do I compete? I have a Skype interview for a highly competivite lecturer position at a UK university (100 applicants).

I don't have large sums of money from external grants nor a fellowship but plenty of other things going for me. The question I have is: how can I up sell not having any grants or fellowships to compete with those applicants who do?

I should add that its in the intersection between engineering and physical sciences and healthcare.
Just a few ideas:

First, obviously you should emphasize the strengths in your profile during the interview, so don't insist too much on this point since it's a bit of a weakness in your case. 

Nevertheless you should at least show that you are aware that it's something that you'll be expected to do should you get the job. Ideally you should have a plan with some specifics: know and mention the main potential sources of funding in your domain, possibly a specific call or two for which you can say that you will apply. If possible/relevant, mention any organization or people in your network who could be potential partners, especially if they already have a good track record in getting grants, and say that you will collaborate with them to obtain funding.
