ive just renewed my contract of 6 months but want to move as the landlady has told me that there is going to be a rent increase. i cant afford anymore rent as we dont get any help either! as i only signed my new agreement 5 days ago, can i retracked it and give her 2 months notice. otherwise if i just give her 2 months notices, she said i still have to pay the 6 months rent. i definately can not afford to do that! HELP!!!!!!

me, my partner and our little girl have lived in a small 2 bed flat for 2 and a half years now, we want more children so we started looking for a 3 bedroom house. our landlady knows this but she has just got us to sign a new tenancy agreement for another 6 months and has informed us that the rent is now being increased by £20 per month. we have now found a 3 bedroom house that is perfect. but where we have just signed a new tenancy agreement for another 6 months that would mean that we give her 2 months notice of moving out, but still have to pay the full 6 months rent. is this right or can we cancel the agreement that we have just signed less than a week ago?! please help!!!!!
