Ask an Property Solicitor. Get an Answer ASAP.
Unfortunately, I cannot see the previous thread. So if you could give me the brief background and then what the current problem is, I will try to help you.
I think the time has come when you need to make the application to court for an injunction to compel him to give you 24-hour access. Clearly, he’s just going to jerk you around for whatever reason and whilst he may be in bad health, that’s unfortunate for him, he cannot use that against you in my opinion and I would just go ahead regardless making the court application. Tell him that he has until next Friday, 18 June 2021, oh 4 PM to reinstate 24-hour access failing which you will immediately make an application to court for an injunction to compel him to comply with the terms of the lease and you will ask the court to award costs against him. I can see no point in hanging around.
It really depends whether you feel competent enough to DIY. You may find that using a solicitor avoids the need to go to court.
However avoid copious correspondence. The letter before action, you can do yourself so don’t waste money on that. You are instructing the solicitor to prepare and serve the proceedings, not to negotiate and waste time on letters. Don’t be used as a moneymaking machine.
