Skylight Installation Costs in Ireland: 2026 Guide
Introducing a skylight can transform your home—filling spaces with natural light and boosting property value. In 2026, the cost to install a skylight in Ireland ranges from around €1,200 for a basic fixed unit, up to €3,000 or more for high-spec, remote-controlled versions. These figures include both supply and professional installation, but your exact price will hinge on a number of elements.
You can expect to pay between €1,500 and €2,000 for a ventilated (manual opening) skylight, while larger or more complex models, especially those featuring electric controls or triple glazing, can stretch beyond €3,000. Prices tend to be highest in Dublin, reflecting elevated labour rates. Keep in mind that VAT at 23% applies, and though SEAI grants can help with some home improvements, skylights currently aren't covered under their schemes.
Ultimately, there's more to budgeting for a skylight than the sticker price. Factors like your roof shape, size and number of skylights, glazing choices, and installation access all have a bearing. We'll break down what affects costs, offer tips for finding a reputable installer, and answer the most common questions Irish homeowners have.

Main Factors Affecting Skylight Installation Costs
Several considerations influence the final cost of installing a skylight in Ireland. Understanding them upfront can help you anticipate your budget.
- Type of skylight—fixed types are the most affordable, while manual and motorised (electric) models cost more.
- Size and glazing—the larger the skylight or the more advanced the glass (e.g. triple glazing), the higher the outlay.
- Roof complexity—if your roof has a complex structure or the installation area is difficult to access, expect increased labour charges.
- Number of skylights—installing multiple units together may reduce the per-unit price through small volume discounts.
- Location—Dublin and other major cities usually have higher installer fees and material markups.
Types of Skylights and Typical Price Ranges
In Ireland, your main skylight options fall into three categories. Each has its own price range and suitability depending on your needs.
- Fixed skylights—Non-opening, best value, start at around €1,200 installed. Ideal for adding daylight to attics or corridors.
- Manual/ventilated skylights—Can be opened for ventilation; expect to pay €1,500–€2,000, depending on mechanisms and size.
- Electric/remote-controlled units—Offer motorised opening and closing, with prices typically from €2,000 to over €3,000 for top-of-the-range models and premium glass.
Grants, Regulations and VAT: What Irish Homeowners Need to Know
Currently, SEAI grants do not cover skylight installations, even for energy-rated glazing. It's vital to ensure that any installation meets Irish building regulations for structural integrity, weatherproofing, and energy efficiency.
VAT at 23% applies to all home improvement projects, including skylights. Quotes should clearly indicate whether VAT is included to avoid surprises.
How to Get the Best Value from Your Skylight Installation
- Always obtain multiple written quotes from reputable, experienced skylight installers.
- Ask if there are additional charges for complex roofs or access restrictions.
- Check that your installer is appropriately certified and insured.
- Choose products with strong energy ratings—this can improve home comfort and help cut long-term heating bills.
- Confirm your work will comply with all relevant building regulations.
Maintaining Your Skylight for Longevity
Once your skylight is in, regular maintenance will protect your investment and avoid costly problems.
- Inspect seals and flashing twice a year for signs of leaks.
- Clean the glass and any opening mechanisms to prevent dirt build-up.
- Remove debris or leaves accumulating around the skylight on your roof.
- Arrange professional servicing immediately if you notice damp patches or condensation around the frame.
