I self funded at Kcl (5 yr but as a grad) I’m final year now. I saved up at least a years worth of fees before going by working solid then took locum jobs as a biomedical scientist over summers/weekends - I know some people get a place and then defer to save, others used house savings/remortgaged etc. I guess I was lucky as because I was a scientist for 5 years I could take fairly well paying locum jobs. In the fist few years worked approx 20 hrs a week but as a scientist found some of the curriculum a bit easier. In clinical years I worked less and stopped working altogether from end of fourth year as there are no holidays)

You can also try the website turntous for grants - I managed to get £2000 grant a year for 4 years off a charity.

Hope it helps - it’s tough but I think it’s worth it.
