I live in a house with 7 others and we've recently discussed how much rent we are all paying and worked out that the person whose name is on the tenancy agreement is over charging us rent so that we end up paying his rent and bills. what do we do? can he evict us? do we go straight to the landlord? we don't wont to leave this awesome house.
Get out the original rental agreement and find out how many people are allowed to live in that house. I'm going to guess its not 8 people!
If it says 2 or 4 tell him lower the rent to something normal or you all will report him to the landlord. Or four of you go get your own place.
