Change job and notify the police office

Hi everyone, happy holidays!

I live in London and changed my job, therefore I need to notify the police/oversea register office. However, my local police office literally just wrote down the changes onto a form and said she would posted it to the overseas Visitors Records Office . I was surprised that my local police office and the Overseas Visitors Records Office systems are not connected.

My question is that will the PEO office's system show that I have notified the job change in time? How can check prior to the PEO appointment that correct information have been updated. Or the PEO do not keep this infor on their system at all?

Many thanks!
