Does anyone know if the following questions can be asked on a standard application form to be filled in during the interview stage before a job offer is made?

"Are you able to attend your main place of work for the hours applicable to the specific job applied for?"

"Are you aware of any circumstances that would regularly prevent you from attending your main place of work for the hours applicable to the specific job applied for?"

"Do you have any unspent criminal convictions?"

The first two questions are aimed at ensuring that prospective applicants are honest about their ability to turn up for work every day.

Would these questions be deemed unfair under the Equality Act?
