Hi Eleanor_Rigby
The so called Bedroom Tax has an official name of the Spare Room Subsidy. It is only paid by the tenants of Social Landlords. Your Social Landlord may have a Financial Inclusion officer who could assist you in this matter. Hopefully you can contact them online or by email.
Let me know how you get on.
