It's £350 per address/property no matter how many rooms from what is being said. They are saying if you have a spare room in your home in a shared property it's £350 no matter how many people it fits and if you have another spare room you will not get another £350. Same applies if you have an empty property with many rooms, it is a one off payment of £350. This is what they are hiding in how they phrased what they said to make it look like it was per refugee or room, it isn't, that's the bad joke.
Seems abit of a scamming/read the small printscheme. With rising cost of living I can't imagine anyone but the wealthy are able to afford housing a refugee then? I know I certainly couldn't at the moment. Good on anyone who is able to afford that, especially if they take on multiple refugees.
