Heat Recovery Ventilation Installation Cost Ireland – 2026 Guide
Heat Recovery Ventilation (HRV) systems are becoming a steadily more popular choice for Irish homeowners keen to boost indoor air quality, regulate humidity, and minimise heat loss. But how much does it really cost to install an HRV system in Ireland in 2026? As of this year, you can expect to pay between €5,000 and €6,200 (excluding VAT) for a typical home, with the price varying mainly by property size and installation complexity.
For a single-storey dwelling of up to 100 m², installation usually starts at around €5,000. Larger homes – for example, those up to 120 m² or 200 m² – may see costs closer to €6,200, especially where extra ductwork or more advanced systems are involved. Prices can also be higher in cities like Dublin, largely due to higher labour costs. Always confirm whether your quotes are VAT-inclusive—energy-efficient installations are generally subject to 13.5% VAT.
Grants from the Sustainable Energy Authority of Ireland (SEAI) may be available if you’re upgrading your entire home’s energy performance as part of a deep retrofit or One Stop Shop scheme. However, for standalone HRV installations, direct grant support is still limited. It pays to shop around, get multiple quotes from SEAI-registered installers, and consider incorporating ventilation works into a larger home energy upgrade for best value.

What Is a Heat Recovery Ventilation System?
Heat Recovery Ventilation (HRV), or Mechanical Ventilation with Heat Recovery (MVHR), is a mechanical system that supplies fresh air to your home while retaining most of the heat energy from the outgoing stale air. This keeps your home both well-ventilated and energy-efficient, and is particularly valuable in highly airtight new builds or major retrofits.
Breakdown of HRV Installation Costs in Ireland
The exact cost of installing a heat recovery system will depend on several factors, but current Irish estimates (2025/2026) are as follows:
- Up to 100 m² single-storey dwelling: Approx. €5,000 (ex VAT)
- Up to 120 m² single-storey dwelling: Approx. €5,500 (ex VAT)
- Up to 200 m² single-storey dwelling: Approx. €6,200 (ex VAT)
- Larger or multi-storey homes: Likely higher, due to extra materials and labour
- Urban/greater Dublin area: Add 5–10% for city logistics and higher wages
- Standard VAT on installations: 13.5%
Key Factors That Affect HRV Installation Costs
- Property size and layout – More rooms and a more complex footprint require more ductwork.
- Ducting route and concealment – Retrofitting ductwork into existing homes is trickier and dearer.
- System specification – Advanced models or higher airflow capacity add to equipment costs.
- Air-tightness – Highly airtight homes especially benefit, but may affect choice of system.
- Install location – City installs (e.g. Dublin) usually attract a higher premium.
- VAT inclusion – Quotes can be misleading if VAT is left out, so clarify up-front.
For the most accurate estimate, it’s best to book a technical assessment of your home with an experienced, SEAI-registered contractor.
Can You Get a Grant for HRV in Ireland?
Direct SEAI grants for HRV are not universally available. However, if you’re undertaking a wider home energy retrofit—such as through the SEAI’s One Stop Shop scheme—you may qualify for support that includes MVHR or ventilation improvements as part of the works.
Always check current SEAI guidelines or speak to a registered One Stop Shop provider for the latest grant eligibility details. Grants and eligibility rules change regularly and bundling several upgrades at once often unlocks larger supports.
Smart Steps Before Installing HRV
- Gather multiple quotes from SEAI-registered installers.
- Request a detailed technical survey for suitability and accurate pricing.
- Plan HRV installs alongside other upgrades (like insulation or heat pump) if possible.
- Ask if VAT is included in all prices.
- Always verify installer credentials and previous experience with MVHR systems.
Frequently asked questions
Are HRV systems worth the investment in Irish homes?+
Yes, HRV systems significantly improve indoor air quality, reduce condensation, and help preserve warmth. They are especially effective in airtight modern homes or after deep retrofits. While the initial investment is not small, benefits to comfort and energy efficiency often pay off over time.
What is the typical lifespan of a heat recovery ventilation system?+
A properly maintained HRV system should last 15–20 years or more. Regular filter changes and annual servicing will help you get the best performance and longevity from your system.
Do I need planning permission to install an HRV system in Ireland?+
In most residential cases, planning permission isn’t required for internal HRV retrofits. However, if external vents or significant alterations to the building exterior are needed, check with your local authority.
Can I install HRV in an existing (older) property?+
Yes, HRV can be retrofitted to existing homes, but installation can be more challenging and costly compared to new builds due to the complexity of hiding or routing ductwork.
How can I ensure my HRV installer is properly qualified?+
Always choose an installer who is SEAI-registered and experienced with MVHR systems. Ask for customer references and examples of previous work before hiring.
