How Much Does Home Ventilation System Installation Cost in Ireland? (2026 Guide)
Indoor air quality is increasingly important—whether you're renovating or building a new home in Ireland, a well-designed ventilation system keeps your living space fresh, healthy, and efficient. In 2026, the cost to install a home ventilation system can vary widely, depending on the technology, your home's size, and how complex the job is.
As a rule of thumb, homeowners can expect to pay between €1,500 and over €10,000, inclusive of design, supply, and installation. For a straightforward Mechanical Extract Ventilation (MEV) system in an average semi-detached house, costs settle around €1,500–€3,000. Opting for more advanced Heat Recovery Ventilation (HRV) or Mechanical Ventilation with Heat Recovery (MVHR) systems, commonly installed in energy-efficient new builds, pushes costs to the €4,500–€10,000+ range.
This guide breaks down current Irish prices, explains what drives costs up or down, covers regional and VAT variations, and offers practical advice so you can budget smartly and make the right choice for your home.

Types of Home Ventilation Systems Available in Ireland
Irish homeowners have a choice of ventilation systems to fit every property and budget. The three main options are as follows:
- MEV (Mechanical Extract Ventilation): Ideal for most standard homes, this system continuously removes stale air from kitchens, bathrooms, and utility rooms.
- HRV (Heat Recovery Ventilation): Suitable for homes focused on energy efficiency, HRV units extract stale air and recycle its warmth, bringing in fresh filtered air with much of the original heat retained.
- MVHR (Mechanical Ventilation with Heat Recovery): The most comprehensive option, combining forced extraction and supply with highly efficient heat recovery—commonly found in modern passive or airtight homes.
Key Factors That Influence the Cost
- Property size and layout: Bigger houses or those with unusual shapes generally need longer duct runs and/or larger systems, raising costs.
- New build or retrofit: It's simple and much cheaper to install ventilation in a new build compared to fitting it into an existing home, which may require more labour and specialised skills to conceal ductwork.
- Features and specification: Items like high-grade filters, smart controls, and increased heat efficiency add to the price but may make sense in some households.
- Brand and efficiency: Top-tier brands charge more upfront, but may cost less to run and last longer.
Regional Variation: Dublin Versus the Rest of Ireland
Not all parts of Ireland are priced alike. Expect to pay higher rates for both labour and materials in Dublin than elsewhere. On average, ventilation system installation costs in Dublin run 10–15% higher, owing to increased demand and cost of living. For those outside the capital, it's worth shopping around as local providers may offer better value without sacrificing standards.
Grants, VAT and Financial Considerations
The SEAI currently supports energy upgrades, and while there's no direct standalone grant for ventilation systems alone, they may be eligible as part of a whole-home retrofit. It's well worth checking directly with SEAI or a registered contractor for the latest criteria.
In terms of VAT, a reduced rate of 13.5% generally applies to home energy upgrades such as ventilation. Confirm this with your contractor and budget accordingly—the saving can be significant compared to the standard rate.
Essential Tips Before Installing a Ventilation System
- Get at least three quotes—ideally from SEAI-registered contractors with solid track records.
- Ask for a professional assessment or survey to ensure your chosen system matches your home's needs and complies with Building Regulations.
- Confirm what's included in the quoted price: does it cover design, supply, commissioning, and VAT?
- Enquire about ongoing maintenance and the cost of replacement filters or service visits.
- If considering a retrofit, be prepared for some disruption, especially with ductwork installations in finished homes.
Frequently asked questions
What is the average cost of a home ventilation system in Ireland in 2026?+
In 2026, installing a home ventilation system typically costs between €1,500 for a simple MEV and up to €10,000+ for a top-tier MVHR system in a large or airtight home. HRV systems fall between €5,000 and €9,000.
Are there SEAI grants for home ventilation systems?+
Ventilation upgrades can sometimes be supported through SEAI grants when included in a comprehensive energy retrofit. There is no specific standalone grant for ventilation systems, so check with SEAI or your contractor about eligibility under whole-home schemes.
Is it cheaper to install ventilation in a new build than in an existing house?+
Yes, new builds are usually much easier and less costly for fitting ventilation. Retrofitting can require more labour for ductwork and making good, so expect higher prices for existing homes.
How much extra does it cost to install in Dublin?+
Ventilation system installation prices in Dublin are generally 10–15% higher than in other regions due to higher labour rates and stronger demand.
Does the reduced VAT rate apply to home ventilation systems?+
Yes, most home energy upgrades, including ventilation systems, qualify for the reduced 13.5% VAT rate in Ireland as of 2026. Always confirm with your contractor or Revenue for your specific project.
Is regular maintenance required for ventilation systems?+
Yes, ventilation systems should be serviced periodically. Expect an annual or biennial maintenance visit to cost about €100–€220, depending on system complexity and your location.
