Change/update to details after naturalisation application

[hardikrs]

Hi all,

I made naturalisation application (Form AN and Form MN1 - 2 adults, 2 children) in January 2017, and did the biometrics in February 2017. My wife has since changed job (her details in the form were accurate on the date of the application). How do I inform the authorities of her change in employment and her new employer details etc. ?

Also, Do I have to update the authorities ?

Thanks all.
