Thank you - that is helpful.
The Tenancy is in the name of 3 students, my son being one. It commenced on or around 12 June and there is an e-mail trail of the first tenants to arrive trying to seek a resolution of these issues from that date.
Our son moved in yesterday, having returned to the UK and moved out immediately - it is is his room that is affectd by damp and is subject to an improvement order (for damp) by the Environmental Health of the local Council. He also noticed that the Gas Safety certificate was invalid and out of date and decided not to remain in the property - so he has not sent a single night there.
The other two Tenants, whilst trying to rectify these issues, did not inform my son of any of this until yesterday when he came to take up possession and then left immediately.
Given that there are three contractual parties as tenants to the Agreement, of which he is one and they are jointly and severable liable, does this affect his rights?
In reference to a substantial breach, where or by which Act is the same governed so that I can make a clear reference to the statutory meaning of this term?
