ABSOLUTELY NOT.
Debt collectors are just private citizens like you and I and have no rights what so ever as regards entering your property.
The rules for bailiffs are a little more complicated. Normally when someone takes you to court for non payment of monies they will use the County Court. If you do not pay when ordered to do so by the County Court, the Plaintiff may apply for a warrant for the bailiffs to visit you.
A County Court Bailiff has no more right to force entry into your home than anyone else - however, they are allowed to enter through an open door or window, but they are not allowed to force entry.
If you invite the bailiff in then he can remain and insist that you either pay him in full or sign a walking possession. Once he has a walking possession signed by you, this then gives him the authority to force entry on a subsequent visit if you do not pay.
So if you ever get visited by a County Court Bailiff and you haven't signed a walking possession, don't invite him in and keep your doors and windows closed. You do not even have to open the door to him.
There are different rules for Magistrates Court Bailiffs and they are used by the police for criminal matters such as fines, non-payment of council rates, electricity & gas among others. They can force entry on a first visit.
