Means tested benefits are all subject to the Habitual Residency Teast as stated earlier. The benefits office will also consider if you have the right to reside in the UK, but as a UK passport holder, that part should be OK. Nationality is not relevant as they will purely condier if you are normally resident in the UK. If you have been living overseas for a length of time, it is likely you may be found not normally resident. Remember, all social security decisions carry appeal rights of one month so if you do not agree with a decision, you must contact the benefit office as quickley as possible to tell them that you would like the decision looked at again.Depending what country you have come from and what arrangements are in place between UK and the other country, you could be eligible for Jobseekers Allowance or Incapacity Beneift based on National Insurance paid over seas. Again, ask the benefit office about this. People over state pension age may also be eligible to state pension based on national insurance paid in UKbefore leaving and the pension service may also count National Insurance (or equivalent) paid overseas.
