Landlords, agents, or their representatives generally need the tenant's consent or must give notice before entering the property. Tenants can also permit entry at any time for any reason.

Minimum Notice Periods:
Here's a breakdown of reasons for entry without consent and the minimum notice required:

Property Inspection: 
At least 7 days' written notice (up to 4 times a year).
  
Repairs or Maintenance:
At least 2 days' notice.
  
Urgent Repairs:
No notice required for emergencies like burst pipes or gas leaks.

Health and Safety Obligations: 
At least 2 days' notice for inspections related to safety measures.

Smoke Alarm Inspection or Replacement:
Notice required, ranging from 1 hour to 2 days.

Property Valuation:
At least 7 days' notice once a year.

Photography or Videos for Advertisement:
Reasonable notice, allowing the tenant to move belongings out of the picture frame/video scope.

Showing the Property to Prospective Tenants:
Reasonable notice, except in emergencies or cases of abandoned property.

Limits and Conditions: 
There are restrictions on entry times (usually not permitted on Sundays, public holidays, or outside 8 am to 8 pm). Landlords should notify tenants of an approximate entry time and avoid overstaying.

Entry Conditions:
The landlord or their representative must have written consent, display it to the tenant if present during entry, and adhere to specific conditions.

Tenant Absence:  
If the tenant isn't home and proper notice has been given for a valid reason, entry without consent is allowed. However, if the tenant obstructs entry despite proper procedures, they might breach the agreement.

Alternative Arrangements:
Tenants can arrange for someone else to be present or give written permission for entry in their absence to avoid disputes.

Compliance is Key: 
Landlords, agents, or their representatives must follow these rules. Tenants can contact the Tribunal for serious or persistent issues or damage to goods.
