Is there a place to give old wheelchair that needs a little TLC but useable?

Hi, 

I have recently got myself a power chair as manual use of the wheelchair became to much with joint pain.

I haven't been able to use it for some time, and it needs a little TLC and new tyres but would like to know if there is anywhere I can contact that would take it for free and refurb it so someone else could benefit from it ?

As it is a foldable and lightish weight
