I moved last January into a home (old converted church). On the floor plans in Rightmove a loft room was included; it was also shown by the estate agent when we did the viewing (a proper room, more like a third floor, perfect for habitation). I signed the tenancy agreement and a week later after moving in, the owner confirms that they loft room is out of bounds and that the estate agents were instructed to not show it to prospective tenants as part of the available space.
In addition, the building used to be a commercial studio and they hadn't requested the change from business rates to domestic premises, which has meant we haven't had any waste disposal since it's still classified as a commercial business. I have been chasing the council myself(estate agents have been completely useless and have done nothing, I was the one to log the initial request even with the council) for the past four months but it's moving slow and I am left with no rubbish collections and having to pay someone to come and collect our waste. To add insult to the injury, the council has also confirmed that I will be indeed by charged council tax from the date I moved in. I feel this is something that should have been sorted before starting any tenancy.
I have had enough so my question is, can I terminate my tenancy early due to having been misled and how do I do this if I find resistance from the estate agent/owner? There's no mention of break clause in the agrement. The loft room is more than a third of the advertised space.
Thank you
