Address change information to UKVI

[stalemate1123]

I have been on the Tier 2 visa for 4.5 years and will be applying for my ILR later this year. Throughout this span I have stayed with a single employer.

At the beginning of my visa, I was staying at my uncle's house and gave it's address to UKVI and my employer. Since then, I have moved twice and have recently moved to the third place. I was checking online and came across information that I have to register my address with UKVI every time I move. I was naive and never bothered to check earlier. My limited post was coming to my uncle's home and it was easier for me to collect from their house where the post had some privacy rather than getting it delivered to my new addresses after moving as I was sharing with strangers.

What are the implications of this naivety, and how do I report all previous changes to UKVI? I know about the CoC form but I'm more concerned about my P60s. My employer has an online portal to issue P60. When I check through that, it shows my current address (which I'm updating for UKVI) as my address even for the P60 of the year 2012. I guess they add the address based on where I'm living currently.

Thank you in advance for your advice.
