I have had a lease on a property for ten years, I recently renewed to another ten year lease. A few months back I decided to change the business use to a coffee shop which the freeholder wanted £6000 for to give me permission, I'm a sub tenant but the tenant dropped the debt on me. However as it's a new business and this charge is way out of what I can afford I am having trouble paying my rent this quarter. I've never missed a payment in ten years prior to this. It is now past the 14 day period on my tenancy that says the lease can be forfeited but my landlord won't reply to my emails about it. Is there a time limit after the 14 days that he has to say if he's forfeiting or can it be whenever he wants. Thanks for any help.
