Disclaimer - This is not legal advice, it is my understanding of the law however.tl:dr - Not really.The Right of Reasonable AccessA landlord is a right of reasonable access to carry out repairs or in an emergency. It doesnu2019t sound like this is applicable in this circumstance.The Right to Enter to Inspect the State of Repair of the property etcThe second right as owner of the property is a right to enter to inspect the building, this does however give the tennant 24 hours notice before entering.The visit should be at a reasonable time of the day and you can have a witness present if you wish.In the last period of a tenancy the landlord can also bring people who may be the new tennant around to the property but again, 24 hours should be given.So providing the landlord gave you the notice which it sounds like she did, and she isnu2019t coming around at a rediculous time there isnu2019t a huge amount you can do.It would be helpful if you could say why the landlord wanted to visit, and also your definition of harassment probably isnu2019t the legal definition so perhaps also say what she is doing to cause harassment.
