Enquiry for extended stay out of UK

Hello Team,

I am currently I am on Tier 2 General Visa and working in London, United Kingdom. I am an Indian citizen and came to India on Feb 6, 2020 for paternity leave. Because of the current situation for Corona Virus worldwide and the situation in UK, I am unable to travel to London and stuck in India. This is indeed affecting the number of days I will be out of UK as I will be eligible for a permanent residency in 2022. I know the rule is you cannot stay more than 180 days out of UK in any point of time.

I just want to know for this unforeseen situation I have to inform anyone in Home Office, UK or there is any other process I need to follow.

Thanks, Sujit
