Thought I'd join you on here as I've recently got into saving.
I have a Barclay's ISA (Golden ISA, Issue 2) and have ~£4.5k in there at the moment. I get just over £7 per month interest on it which is better than nothing. Hope to have £6k in there by the time I graduate, then can concentrate on working full time.
I'm saving up for a flat in a new development near where I live. They sell at the moment for £45k for a one bedroom, so it seems like a good investment while the property prices are rock bottom. Plan to buy it mortgage free within two years and then rent it out while I'm still living in my partner's flat. Or move into our shiny new flat and rent his out; doesn't really matter.
EDIT: Also have £2k of Premium Bonds which were bought on my behalf when I was born. Not sure whether they're best staying as Bonds, or whether they'd earn me more in an ISA, but as my Grandad gave them to me I'm going to leave them as Bonds for now, as that was the gift he gave me.
EDIT 2: I'm 21 by the way, and have worked in whatever job was legal since I was 13. Have a slight obsession with money, however saving rather than splurging has only been a recent development.
