Housing benefit checks

Hello,

I have recently been asked to verify some information regarding my housing benefit with my local authority. I am over pension age and receive housing benefit.

I received a letter asking me to log into a portal and confirm if I live alone, if I have any other earnings etc. I was told that these are interventions done by the local authorities on claims where they suspect a change will be reported. As I am a pensioner I don’t see how I fit in this but completed the forms.

I was wondering if this is a common practice for local authorities to do?

Thanks
