In London, almost nothing - I rented in Guildford (outside London but still in a commutable area) and a tiny one-bed flat cost £650 (7 years ago); someone I know currently rents a room in a shared house in Clapham for around £1000 a month

If you want a self-contained flat for yourself only, you're going to need more than that.

Get an idea of what's around on RightMove, but be prepared for that price to compromise on the kind of area you live in

I have a friend in the UK and she told me that 900 pounds would get you a 3 bedroom apartment. So 500 is probably a one bedroom. This is in Lincoln. Not sure how far that is from London.

I think you would pay £500 a week.
