Hello my name is ***** ***** I will help you with this.
You can make whatever rules you want in terms of who can rent.
However the only caveat to that is discrimination
You can not discriminate on the grounds of race, colour, religion, sex, age etc
There is nothing to stop you making rules to prevent DSS tenants.
As long as you are treating everyone in the protected groups equally then you can make whatever rules you want.
For example, if you have someone who is white and on benefit and someone black on benefit - as long as you said no to both because of your rules that would be fine. If you said yes to the white person because they were white, this would be discrimination
But you can make any rules you want and if that is not to have anyone on benefit then that is something you can do
For more details on discrimination and in particular the Equality Act 2010 you can visit this website for more help:
Can I clarify anything for you about this today please?
That is all at the moment. Thank you.
I hope I don't have further questions.
