In the UK there's a charity or government funded service called 'Citzens Advice Bureau' where you can get free advice on issues such as tenancy. A lot of solicitors will offer a free legal advice session for the public on certain quiet days.
Also, there are strict laws that apply to landlords in the UK: you must give 3 months notice to a paying tenant before kicking them out and the property must be fit for habitation (fire exits, smoke alarms and good sanitation).
I've never heard of rental references before but that sounds like a real opportunity for abuse and bullying.
I think it pays from the offset with people in positions of power to let them know you're aware of the law and your rights. It makes them think twice about what they can get away with.
