Answer
No, a commercial landlord will need the permission of the tenant before entering a property. A commercial landlord may need to come onto the premises to fix issues and check any problems such as leaks or a fuse box for example, but they will need to ask you first by giving you at least 24 hours’ notice. They may however be able to enter the property if the tenant hasn’t paid the rent for instance or if there is an emergency such as a fire or flood.
If a landlord enters the property without your permission and without good reason, you may be able to take the matter further by raising a complaint or dispute.
