I have come across this problem before with a NASS household of four women. It looks like any "extra item" has to be requested from the Home Office, however try your local NASS office first!

All the forms relating to Section 4 support - which have changed at the beginning of his month (July 2009) - can be found here: http://ukba.homeoffice.gov.uk/asylum/support/apply/section4/

To request extra support like travel expenses and additional needs, you will need the "Provision of services and facilities application form".

You can also contact the Refugee Council or drop in at one of their One Stop Shop services for help with your issue at:
