You have probably seen a pop-up offering you the chance of a telephone call at an extra cost. It is up to you whether you have a telephone call or not but do bear in mind that a 15-30 minute telephone call covers an awful lot of ground and you can get an awful lot of information in that time. So you can ignore it or go ahead or go ahead later. It’s your choice.
Meanwhile, we can carry on on here.
Once notice has been given and accepted, then it is not possible to retract it unilaterally or for the landlord to decide unilaterally, once they have accepted it, that they now no longer want it.
That is of course unless you both agree, which you don’t agree..
I haven’t seen your lease but in a properly drafted lease once you were overdue by 14 or 21 days in paying rent, the landlord can simply repossess the property and lock you out without a court order. Much different than residential property but the provision must be in the lease.
Otherwise what you would do is simply stop paying rent and that the arrears take account of the deposit.
You would have proof that you paid the deposit because you would have a bank statement.
There is no legal requirement to keep the deposit separately although if he goes bankrupt, the deposit would go with it. What he cannot do however is use that deposit money as his own because the money does not belong to him.
It would only make the lease invalid if it struck to the very heart of it and I don’t think it does.
Do remember that I can only give you my opinion.
Another lawyer may have a different opinion. Litigation needs at least 2 parties and neither goes to court expecting to lose.
Nonetheless, one of them does, even though they have been told by their respective legal advisers that they have a good chance of success.
If there was a black-and-white answer to every legal problem there would be no need for anything to ever proceed to court.
However that opinion is based upon this being in court and you are a long way from that so I would tell him exactly what you are suggesting, he has not kept the deposit in a separate account therefore he’s in fundamental breach of the lease and as such the lease is invalid and as such you can walk away at any time but you will stay until February as agreed
He is not going to find it particularly easy to argue or instruct solicitors if he is out and about
