Change of address help

So I changed my address on government gateway in August but have since started a new job where they have my old address as I applied for the position before I moved, so because of this now I’ve been paid from the job it’s changed my address back to my old one, I have notified my employer of the change of address so once they update it will it change back on government gateway on its own or do I need to change it again myself?
