My guess is that since you will likely be holding personal information on your tenants (names, addresses, telephones, bank accounts etc) they will be wanting to ensure that this is done securely in line with data protection and processing regulations with a nominated data protection officer.
Since they are essentially funded by the penalty revenues they levy there is a strong incentive to increase their scope.
In fairness it’s not a bad thing when you see the cavalier manner that many organisations used to have in protecting your data from getting into the hands of the less desirable elements of society.
