Ventilation Solutionsfor Landlords & Rental Properties
MVHR, PIV, and extraction systems to prevent condensation
Quick answer
Ventilation solutions address condensation mould — the most common mould type in rented properties — by controlling indoor humidity through mechanical systems. Options include MVHR (mechanical ventilation with heat recovery), PIV (positive input ventilation), extractor fans, and whole-house ventilation strategies. Proper ventilation prevents condensation mould from forming rather than treating it after it appears.

Condensation mould caused by inadequate ventilation is the most common mould complaint in the private rented sector and a frequent source of landlord–tenant disputes. Under Awaab's Law, landlords cannot simply attribute mould to 'tenant lifestyle' without investigation — if inadequate ventilation is a contributing factor, addressing it is part of the landlord's obligation.
What Should You Expect?
A ventilation survey will assess air exchange rates in key rooms, identify condensation risk areas, and recommend appropriate mechanical solutions. PIV units are unobtrusive loft-mounted fans that are quick to install. MVHR requires more significant installation but provides superior performance and energy efficiency. Extractor fans in bathrooms and kitchens are the minimum baseline requirement.
Ventilation Solutions& Awaab’s Law
Condensation mould triggered by poor ventilation is a hazard that falls within Awaab's Law scope. If a tenant reports mould and the cause is condensation, addressing the ventilation is part of the landlord's remediation obligation — not an optional extra. A ventilation specialist can provide a written assessment that documents the cause and recommended solution.

Frequently Asked Questions About Ventilation Solutions
- What is the difference between MVHR and PIV?
- MVHR (mechanical ventilation with heat recovery) extracts stale air from wet rooms and supplies fresh, filtered air to habitable rooms, recovering heat in the process. It requires a central unit and ductwork throughout the property. PIV (positive input ventilation) takes fresh air from the loft, conditions it, and distributes it through a single central ceiling diffuser — simpler to install and effective for most condensation problems.
- Can I just tell tenants to open windows more?
- No. Under Awaab's Law, if the property lacks adequate ventilation — missing or underperforming extractor fans, no trickle vents, or inadequate whole-house air exchange — the landlord is obligated to address the physical deficiency. Tenant advice alone does not satisfy the legal duty to provide a hazard-free home.
- How much does a PIV unit cost to install?
- A PIV unit including installation typically costs £400–£800. It is one of the most cost-effective interventions for condensation mould in properties with loft access. MVHR systems are significantly more expensive, typically £3,000–£8,000 installed, and are better suited to new build or substantially renovated properties.
