Heating and Hot Water Faults for Tenants in Portugal

Maintenance & repairs (landlord duties, minor repairs) 2 min read · published September 11, 2025

If you rent a home in Portugal and face a heating or hot water fault, know that you have rights and practical steps to follow. As a tenant, keep written communication with the landlord, document the fault with photos and contact records, and request a repair within reasonable deadlines. In cases of habitability failure — lack of heating or essential hot water — there is a right to intervention and formal procedures when the landlord does not act. This article explains the landlord's obligations, what you should do first, how to use legal deadlines and where to seek official support, with clear examples to help you act safely and effectively.

What the law says

In Portugal, the rental regime establishes duties of maintenance and habitability that generally require the landlord to ensure heating and hot water under normal use. Check applicable legislation for deadlines and formal responsibilities.[1]

Tenants are entitled to a habitable dwelling, which typically includes essential services such as hot water when expected.

Practical steps

When you detect the fault, follow these clear steps to protect your rights and speed up the repair.

  • Contact the landlord in writing and request intervention indicating dates and symptoms.
  • Record the communication (email, registered letter or written message) and set a reasonable deadline for repair.
  • Take photographs, record dates and times and keep receipts for related expenses.
  • If there is no essential heating or hot water, request urgent repair and document the urgency.
Keep dated copies of all communications and evidence.

When to advance formally

If the landlord does not respond or repair within the deadline, the tenant may use official procedures to demand intervention, including formal requests to competent authorities and, where appropriate, court procedures or recourse to the Tenant and Landlord Desk.[2]

Responding to a notice or legal communication within deadlines is essential to preserve your rights.

Frequently Asked Questions

Is the landlord always obliged to fix the fault?
Yes, the landlord generally has the duty to maintain the property and carry out necessary repairs for habitability; communicate in writing and keep evidence.[1]
