Is a non-EEA national (in the UK with right of residence) who is the family member of an EEA national (in the UK) entitled to obtain housing benefit if working in the UK? Does the EEA national need to be working?

The EEA national needs to be the claimant, and it doesn't matter if he/she is or is not working, so long as they meet the definition of being 'economically active' (and this can include periods of unemployment). The non-EEA national should be listed as the partner (and again it doesn't matter if he/she is working), and the claim should be paid if there is entitlement (it might take some weeks/months to process though, esp. if the non-EEA national has not yet applied for a NINo. (and they would be entitled to one for the purposes of claiming HB).

Hope this helps...
