Landlord's Guide to Damp: Legal Obligations & Best Practice

Damp and mould are among the most common complaints from tenants, and landlords' responsibilities in this area have been strengthened significantly in recent years. Understanding your obligations is essential to avoid legal action and maintain good tenant relationships.

Your Legal Obligations

Section 11 of the Landlord and Tenant Act 1985

Under Section 11, landlords are responsible for keeping the structure and exterior of the property in repair. This includes:

• The roof, walls, and foundations
• Gutters, downpipes, and external drainage
• Windows and external doors
• Installations for water, gas, electricity, and sanitation

If damp is caused by structural defects - such as a leaking roof, failed pointing, or broken guttering - the landlord is legally responsible for the repair.

Homes (Fitness for Human Habitation) Act 2018

This Act requires that properties are fit for human habitation throughout the tenancy. Damp and mould can make a property unfit if they pose a risk to health. Landlords can be taken to court if they fail to address these issues.

Housing Health and Safety Rating System (HHSRS)

Local authorities assess rental properties using HHSRS. Damp and mould growth is a Category 1 hazard (the most serious) if it presents a significant risk to health. If identified, the council can require landlords to take action.

What Are You Responsible For?

Landlord Responsibilities

As a landlord, you are responsible for damp caused by:

• Structural defects: Leaking roofs, failed pointing, cracked walls
• Rising damp: Failed or absent damp proof course
• Penetrating damp: Water ingress through walls or windows
• Inadequate ventilation: If the property lacks sufficient ventilation
• Blocked gutters/drains: External maintenance issues

Tenant Responsibilities

Tenants are generally responsible for:

• Using ventilation provided (extractor fans, trickle vents)
• Heating the property adequately
• Not blocking air vents
• Reporting damp problems promptly
• Lifestyle factors (excessive drying of clothes indoors, etc.)

Common Damp Scenarios for Landlords

Scenario 1: Tenant Reports Mould in Bedroom

First step: Arrange an inspection. Don't assume it's the tenant's fault. Check for:

• Ventilation provision (are there trickle vents, extractor fans?)
• Signs of penetrating damp from outside
• Window condition and seals
• General property ventilation

If the property lacks adequate ventilation, consider installing a PIV system (£500-£900) which is often cheaper than ongoing disputes.

Scenario 2: Rising Damp in Victorian Terrace

This is clearly a landlord responsibility. Rising damp requires professional treatment - typically DPC injection and replastering. Costs for a terraced property are usually £1,500-£3,000, but failure to act can result in:

• Council enforcement action
• Tenant compensation claims
• Property damage worsening over time
• Difficulty re-letting the property

Scenario 3: Condensation Throughout Property

While lifestyle factors play a role, a property should be able to cope with normal levels of moisture production. If condensation is widespread, consider:

• Installing or upgrading extractor fans
• Adding trickle vents to windows
• Installing a PIV system for whole-house ventilation
• Providing tenants with clear guidance on ventilation

Best Practice for Landlords

Prevention

• Ensure adequate ventilation is installed before tenancy starts
• Service extractor fans annually
• Clear gutters regularly
• Address any damp issues before they worsen
• Include ventilation guidance in tenant welcome packs

When Issues Arise

• Respond promptly to tenant reports (within 14 days)
• Get a professional damp survey - don't guess
• Document everything in writing
• Act on survey recommendations
• Follow up to ensure the issue is resolved

Documentation

• Keep records of all repairs and maintenance
• Document tenant reports and your responses
• Retain survey reports and treatment certificates
• Photograph issues before and after treatment

The Cost of Inaction

Failing to address damp problems promptly can be far more expensive than fixing them:

• Council enforcement: Improvement notices and potential fines
• Rent repayment orders: Tenants can claim back rent for uninhabitable conditions
• Compensation claims: For damage to tenant belongings and health impacts
• Legal costs: If cases go to court
• Property damage: Untreated damp causes increasingly costly damage
• Void periods: Difficulty letting properties with known damp issues

Getting Professional Help

A professional damp survey (£150-£300) provides clarity on the cause of damp and the appropriate solution. This is money well spent because:

• It identifies the true cause (not guesswork)
• It provides evidence of due diligence
• It gives you a clear scope of works needed
• Survey reports are useful if disputes arise
