Change of circumstances-inform bank?

Have tracker mortgage moving out and living back home

I am moving out of my house. I had been renting rooms in the house while I lived there, but have decided to move out and rent the whole house. A family are interested in moving in but want to change the esb billing name to their own. I am afraid to do this in case either the revenue or the bank finds out that I have moved out. Am I being paranoid? The house remains my only home and I would hope to move back when my circumstances improve.

very very likely that revenue will find out - & easy for the bank to find out by just checking the PRTB ( assuming you register) but they dont seem to bother.
Never take chances with the taxman
