How Much Does Velux Window Installation Cost in Ireland? (2026)
Replacing or installing a Velux roof window can dramatically improve comfort and natural light in your home, but it’s wise to budget accurately before you begin. In Ireland, the total cost for a standard Velux window installation in 2026 typically lands between €1,200 and €2,000 per window. This figure covers both the price of the window and professional installation by a certified installer.
Actual costs depend on the size and type of window you choose, as well as the complexity of the job. Standard windows and straightforward replacements will sit at the lower end of the range. Advanced models—like electric or solar-powered Velux windows—or particularly tricky roof access can push costs higher. Regional variations also exist, with Dublin installations tending to be pricier. With potential SEAI grants now available for energy-efficient windows, your net outlay may be lower if your home and window choice qualify.
In this guide, you’ll find clear breakdowns of current Velux window prices, what affects installation costs, available grants, and what to look for in a reliable installer. Our aim is to arm you with the details you need to plan your project confidently and avoid financial surprises.

What Dictates the Cost of Your Velux Window Installation?
The price you pay for installing a Velux window in Ireland hinges on several practical factors. Chief among them are the size and specification of the window. Larger or feature-rich models (such as electric-opening or solar-powered Velux windows) command a premium both in supply and fitting.
Roof complexity and site access can also significantly influence your quote. If your roof is steep, has an awkward pitch, or your attic is hard to reach, expect added labour or even scaffolding—these extras typically mean an extra €200–€500 on top of the basic install.
- Size and style of Velux window (manual, electric, solar)
- Type and pitch of roof
- Ease of access (internal and external)
- Number of windows installed together—per-window cost is usually lower for multiples
- Required extras: flashing kits, insulation collars, finishing trims
- Need for structural changes or interior repairs
Velux Window Prices and Installation: What to Expect
For most standard houses in Ireland, Velux window units (supply only) cost anywhere from €500 to €1,200. The commonest types—centre-pivot manual windows—tend towards the lower end. If you’re after remote-controlled electric or solar models, be prepared to budget at the upper limit or beyond.
Labour for a like-for-like Velux replacement typically runs €600–€700 per window, provided the installer isn’t faced with major access or roof issues. The overall supply-and-fit price per window is therefore €1,200–€2,000 in most cases.
Remember, this price may rise if extra work—such as interior plastering, structural work, or scaffolding—is needed. Expect to pay another €200–€500 for challenging roof setups.
Are There Grants for Velux Windows? (SEAI 2026 Grants)
The SEAI (Sustainable Energy Authority of Ireland) introduced new grants for energy-efficient window installations in 2026. This can make Velux replacements a lot more affordable, provided you and your window choice qualify.
- Detached home: up to €4,000
- Semi-detached/end terrace: up to €3,000
- Mid-terrace: up to €1,800
- Apartment/duplex: up to €1,500
- €800 per external door (up to 2 doors) also available
To qualify, your home’s Heat Loss Indicator (HLI) must be 2.3 W/K·m² or lower, and your chosen Velux must have a U-value of 1.4 W/m²K or better. Using an SEAI-registered installer is also essential for grant compliance.
Regional Price Differences: Dublin and Beyond
If you’re in Dublin, expect marginally higher installation quotes due to stronger demand and higher living costs. For example, even small Velux repairs (like fixing a flashing leak) can cost €250–€700 in the capital, whereas similar jobs elsewhere are closer to €180–€580.
For new installations and full replacements, the supply-and-fit price is still mostly between €1,200–€2,000 per window, but the very top end of that range is usually seen in the Greater Dublin area. Getting several quotes is essential for an accurate local picture.
Tips for a Smooth and Cost-Effective Velux Installation
- Get written quotes from at least three SEAI-registered installers
- Check that your chosen Velux window meets SEAI U-value requirements (1.4 W/m²K or better)
- Budget for essentials: flashing kit, insulation collar, any scaffolding or extra finishes
- Ask about discounts if installing multiple windows at once
- Confirm what’s included in your installer’s quote—avoid hidden extras
- Plan your installation outside the busiest seasons if possible, when prices may be lower
