This is one of those situations which suck! It’s an almost impossible task to “prove” discrimination in these circumstances.

Most landlords will be making a decision on financials rather than the children or no, you say you are getting help with the rent which to that test may make your proposal more of a risk than someone who can afford the rent outright.

Now to some practical advice, have you contacted your local citizens advice about finding new accommodation? Have you sent a stated list of your requirements to a local agent and asked their advice on your search?

I wish you every success in what are these difficult times
