Thank you for your reply,just asking as i feel its unfair the rent is so high

I moved into my Housing Association house 9th Dec 2013.I have been with the same Housing Association since 2004. I am in a row of 4 houses and my rent is £105.75 for a 2 bed house. My next door neighbour is paying around £83 for the same house,another neighbour £99 and another £86 all the same bedrooms configuration etc. Is this right ? and do i have a right to appeal against the rent as i am now paying higher than everyone else. Any help would be greatly appreciated
