Unfortunately not all that unusual.  Most people's pensions get paid directly into their bank accounts, and standing orders and direct debits take care of that side of things, so providing there is sufficient money coming into the account, sounding very mercenary, I know, there would be no cause for alarm.  No bank manager is going to wonder why your pensin money is not being withdrawn, because it's none of his business.

That reminds me of years ago when close to my boat moored in a local boatyard was another boat which had been untouched for so many years it was almost black with dirt.

The mooring fee continued to be paid by DD so the boatyard owner had no reason to question the non use or check on the owner.
