If we're being honest, this £10k gift isn't going to help anyone. It'll just inflate the housing market further. It really isn't that hard to pull your finger out and start saving money.
I'm 24, I've been a home owner for over 2 years. I just stopped going out as much, stopped buying expensive clothes, less fancy meals etc and saved that money. Most of my mates from school are still renting or living at home - the difference is they never stopped going clubbing, they all go out and put £70 up their nose, drive home in their brand new German car (on a shit finance deal) and then whinge that they don't have any money to put towards a deposit.
If you're happy with a materialistic lifestyle, that's fine. But it's not anyone else's issue that you can't afford a house.
