The Citizen Advice Bureau at http://www.citizensadvice.org.uk/ offers advice on all benefit matters. You may need to make an appointment to attend your local office. Some Local Councils that provide HIV support Services. Also engage the CAB to meet with their HIV clients once a week usually by appointment. Though this service is typically heavily booked at the present time.

Look to your local council website to see if they provide HIV services in your area.

Benefits & Work found at http://www.benefitsandwork.co.uk/ is a site maintained by someone who was a welfare rights worker. It is a good repository for all benefit advice.

See the forum I have started on Benefits & Work on this issue.
