The Citizen's Advice Bureau (Website: http://www.citizensadvice.org.uk) is an independent charitable organisation that focuses on giving advice on a whole range of subjects.
They are able to offer help in regards to issues such as debt, your rights, and general consumer issues. However, certain bureaux can offer specialist advice, often in conjunction with professional partners such as solicitors.
If things go awry, the CAB can help you to determine a way forward. They will help identify what your rights are, how to move forward with the issues, what kind of back up you can expect from various bodies etc.
