Home Ventilation System Installation Costs in Ireland (2026 Guide)
A properly installed home ventilation system is vital for maintaining healthy indoor air, controlling humidity, and preventing problems like mould. In Ireland's often damp climate, these systems not only help safeguard your home's structure, but can also improve energy efficiency and comfort.
The cost of installing a ventilation system across Irish homes in 2026 depends on the system type, your home's size, and the complexity of the job. For a basic Mechanical Extract Ventilation (MEV) system, prices generally start at around €1,500 and can reach up to €3,000. For more advanced options such as Heat Recovery Ventilation (HRV), expect installation costs to range between €5,000 and €9,000. Mechanical Ventilation with Heat Recovery (MVHR) systems – offering both extraction and heat recovery in a balanced setup – typically cost between €4,500 and €10,000 or more, particularly in large or complex properties.
These price ranges usually cover the design, supply, installation, and commissioning. Dublin and other urban areas often see the higher end of the price spectrum, mainly because of increased labour rates. Factoring in SEAI grants and the standard VAT rate of 13.5% is also important when budgeting for your new system.
Typical Home Ventilation System Installation Costs in Ireland (2026)
| Job | Typical price (incl. VAT) |
|---|---|
| Mechanical Extract Ventilation (MEV)Best for simple extraction; generally lower cost | €1,500 – €3,000 |
| Heat Recovery Ventilation (HRV)Energy efficient, higher up-front cost | €5,000 – €9,000 |
| Mechanical Ventilation with Heat Recovery (MVHR)Advanced systems, suited to full-home solutions | €4,500 – €10,000+ |
| Upgrading with Smart ControlsOptional add-ons; not usually included in basic price | €300 – €1,000+ |
| Retrofitting into Existing HomesExtra for duct routing and disruption | +10–25% over new build |
| SEAI Grant Contribution (if eligible)Contact SEAI or your installer for current grant limits | Varies |
| Annual Maintenance (after installation)Depends on system complexity and filter changes | €100 – €300/year |
| Design Consultation/Assessment FeeMay be deducted if you proceed with the installer | €150 – €400 |
Prices are typical 2026 estimates and vary by job, condition and location.
Understanding Home Ventilation System Types
Modern Irish homes have three main ventilation options, each offering distinct benefits for air quality, energy savings, and comfort.
- MEV (Mechanical Extract Ventilation) – Continuously removes moist, stale air from key rooms (bathrooms, kitchens); lower initial outlay; no heat recovery.
- HRV (Heat Recovery Ventilation) – Both supplies and extracts air, capturing heat from outgoing air to pre-warm fresh air; high efficiency but costs more.
- MVHR (Mechanical Ventilation with Heat Recovery) – Brings together the strengths of both MEV and HRV, best for balanced, full-house systems and ultra-low energy homes.
Factors That Influence Installation Cost
- Home Size & Layout: Larger homes and more intricate layouts need more ductwork, which increases both material and labour costs.
- New Build vs. Retrofit: Fitting during construction is easier and usually cheaper. Retrofitting can mean extra work (and disruption) to route ducts and reach all spaces.
- System Features: Optional upgrades like smart controls or HEPA filtration improve comfort but add noticeably to the price.
- Brand & Efficiency: Premium brands offer greater reliability and efficiency, usually at a higher upfront cost, but can mean lower running costs.
- Regional Labour Rates: Installs can cost more in Dublin and other cities due to higher tradesperson rates.
Making Sense of SEAI Grants and VAT
While SEAI grants in 2026 are focused mainly on whole-home energy upgrades, ventilation may be eligible if wrapped into a larger retrofit package. Always check the latest SEAI guidance or work with a registered contractor to check what’s available for your project.
Don't forget VAT is an extra cost. Ventilation system installs for private residential use are usually charged at 13.5% VAT. Always ask your contractor to itemise this in your quotation.
Tips for Getting the Best Value on Your Ventilation Upgrade
- Request multiple quotes from SEAI-registered or well-reviewed contractors.
- Ask for a detailed breakdown – including VAT, supply, design, commissioning, and maintenance estimates.
- Consider your specific needs: a large home or a family with allergies may benefit from higher-spec systems or air filtration upgrades.
- Plan with the future in mind – choosing a system suited to your insulation level and likely changes to building regulations.
- Set aside a small annual budget for servicing and filter changes to keep the system running efficiently.
Ongoing Maintenance and Operating Costs
After installation, ventilation systems need routine filter changes and checks to stay effective. This generally costs €100–€300 per year depending on system type and filter requirements. Larger or high-spec systems may require more frequent maintenance, particularly if you opt for HEPA-grade filtration.
Well-maintained systems last longer, run more quietly, and perform better. It's a small ongoing investment for the long-term health of your home and its occupants.
Frequently asked questions
Is it worth installing a ventilation system in an older Irish home?+
Yes – especially if your home has issues with damp, condensation, or stale air. While retrofitting can mean extra cost and work, the improvement to comfort, air quality, and building protection is usually well worth it.
Can SEAI grants help with ventilation system costs?+
Potentially. Although there isn’t a direct SEAI grant for ventilation alone in 2026, if you’re planning a whole-home upgrade you may be able to include ventilation costs as part of a wider grant package. Always check with SEAI or a registered installer for the latest information.
Does installing a system increase my home’s resale value?+
A professionally installed, modern ventilation system is considered a plus by most buyers, as it means healthier, fresher indoor air, less risk of condensation, and can lower heating bills in energy-efficient homes.
Are there cheaper alternatives to whole-house systems?+
For some smaller or less airtight homes, localised extractor fans or single-room heat recovery units can be an option. However, they won’t provide full-home protection or the energy-saving benefits of MEV, HRV, or MVHR.
How long does installation take?+
Most installs take several days to a week, depending on home size and system complexity. Retrofitting into existing homes can take a bit longer and may disrupt some rooms during the process.
