Daddima
Paddyann to digress, the Joint Service agreement was designed to get ex-forces priority help with housing, and there’s also an Armed Forces Covenant which does the same. As well as giving a donation, I’d maybe point them in the direction of the British Legion ( that’s assuming they’re fit to do so, as so many aren’t)
Yes, a little research is always useful Daddima and there are official schemes available as well as charities. Besides the RBL, there are also SSAFA, ABF, Soldiers off the Street etc.
These people may not, of course, be ex-services anyway, who's to know?
But it's difficult to find volunteers now to fundraise for Armed Services charities, many are in their 80s and younger people are just not volunteering.
