TL:DR Want to file a legal case against estate agent + builder for false or incorrect information during house booking.
I booked a new build house off plans, while booking in sales office we selected our preferred house number. The agent informed an issue with the back garden of the house, this resulted in us switching the house choice to another house. The agent confirmed our new choice of house doesn't have the issue at all. The new house was 2.5% (9-10K) more costly then our earlier selection. This was all verbal during the booking phase in the office.
Now we are about to get handover of the house and realized the agent mixed up the house no's and ended up giving up incorrect information of the house. Forcing use to rely on the information to change house to the one which has an issue.
My initial communication with agent and builder have been not taken seriously as they believe its a non issue and we would eventual accept the house in the state it is. My solicitor also thinks this is a small issue and could be ignored. However, the is going to cost me 5-8K to fix myself, plus has caused tremendous disappointment and stress for us.
If I close the house deal with a clause/notice to pursue this matter legally to cover the cost in future, do I stand a chance? I would like to avoid the legal hassle as this would not be a big work for the builder to do but I am 100% sure they wouldn't do it to avoid any more possible issues. Would I need any solicitor in future to pursue this case?
