As David above said. I would use most of the funds on your house but treat them to a nice meal.
Look at it this way, if your house is maintained as well as it can be, then you won't be a burden to them, if, for example, your roof starts to leak and you have to ask them to put you up.
So theoretically
you are doing them a favour by being independent and they won't have to worry about your house falling down around you.
I would also shop around for your house repairs as much as possible as £5,000 does not go a long way and you need to make it go as far as possible with your repairs.
What a thoughtful person you are to think of giving it away but honestly, please make sure you are o.k. first.
