How much does it cost to have a new window fitted?
The cost of a fitted window in Ireland in 2026 depends primarily on three factors: the material you choose, your property type and location, and whether you need additional work like plastering or lintels. Here is how the materials stack up.
Cost per window by material (uPVC, aluminium, wood)
Four materials show a clear pattern in pricing and lifespan trade-offs.
| Material | Price range per window (fitted) | Typical lifespan | Main advantage |
|---|---|---|---|
| uPVC double glazed (standard casement) | €400–€800 | 20–25 years | Best value, low maintenance |
| Aluminium double glazed | €600–€1,000 | 30–40 years | Slim frames, modern look |
| Timber (hardwood) double glazed | €800–€1,200 | 40–50 years | Traditional aesthetic, excellent insulation |
| uPVC triple glazed | €500–€1,100 | 20–25 years | Highest energy efficiency |
Four materials, one pattern: uPVC remains 30-40% cheaper than aluminium and roughly half the cost of timber, but the trade-off is lifespan. Timber windows last twice as long as uPVC, which may mean lower lifecycle cost for homeowners planning to stay put for decades. According to Homebuilding & Renovating (UK home improvement magazine), installation costs in Dublin and Cork run 10-20% higher than in rural counties, driven by labour rates and access logistics.
An Irish homeowner with 10 windows who chooses uPVC at €500 each instead of aluminium at €800 each saves €3,000 upfront — enough to cover the full SEAI grant shortfall. But over 30 years, the aluminium option avoids one full replacement cycle, meaning the initial premium may break even.
Additional costs that often catch homeowners out include disposal of old windows (€50–€100 per window), plastering and making good around frames (€100–€300 per window), and lintel repairs if the window opening needs structural support (€200–€500). Always ask your contractor for a line-item quote that includes these extras.
How much does double glazing cost for a 3 bed house?
For a typical 3-bed semi-detached house in Ireland — with 8 to 12 windows across ground and first floors — a full replacement runs between €2,500 and €4,500. The spread depends on material, glazing type, and whether you opt for A-rated energy-efficient glass.
Breakdown per window type and floor
The floor-by-floor breakdown below shows how quickly costs accumulate in a standard semi-detached layout.
| Window group | Typical count | uPVC cost estimate | Aluminium cost estimate |
|---|---|---|---|
| Ground floor (living room, kitchen, hallway) | 4–5 | €1,600–€4,000 | €2,400–€5,000 |
| First floor (bedrooms, bathroom, landing) | 4–7 | €1,600–€5,600 | €2,400–€7,000 |
| Total for 3-bed semi (8–12 windows) | 8–12 | €3,200–€9,600 | €4,800–€12,000 |
The range is wide because some homes have large picture windows or sliders that cost significantly more than a standard casement. An industry guide from Expert Windows (Irish glazing company) notes that partial replacement — swapping only the worst-performing windows — can halve the cost but risks leaving you with inconsistent energy performance across the house.
The implication: a full-house uPVC replacement costs about the same as a used car, but the energy bill savings (typically 20-30% per SEAI (Ireland’s energy authority)) mean the investment starts paying back from month one.
What is the average price of an uPVC window?
A standard uPVC double-glazed casement window, fully fitted, lands between €400 and €800 in Ireland. The exact figure depends on size, style, glazing rating, and your location.
Price differences by style (casement, sash, tilt-and-turn)
Window style significantly changes the price — sash and tilt-and-turn variants command noticeable premiums over standard casements.
| Style | Double glazed (fitted) | Triple glazed (fitted) | Premium over standard casement |
|---|---|---|---|
| Casement (standard) | €400–€800 | €500–€1,100 | — |
| Sliding sash | €600–€1,000 | €700–€1,300 | +25-30% |
| Tilt-and-turn | €550–€950 | €650–€1,250 | +15-20% |
| Bay or bow windows | €1,500–€3,000 | €2,000–€4,000 | +100-200% per section |
Homebuilding & Renovating (UK home improvement magazine) notes that A-rated double glazing typically costs 10-15% more than standard C-rated glass but delivers the energy savings needed to qualify for SEAI grants. Triple glazing adds another €100-€300 per window.
The catch: the cheapest quote is rarely the best value. Thirty percent of Irish homeowners who took the lowest quote in a 2024 survey reported issues with fitting quality or post-installation service, according to consumer feedback compiled by Which? (UK consumer advocacy group). A quote should always itemise frames, hardware, installation, and waste removal so you can compare apples with apples.
Is it worth replacing 20-year-old double glazing?
If your double glazing is two decades old, the answer is almost certainly yes — but let’s look at the evidence.
Signs your windows need replacement
The most obvious red flags are condensation between panes (indicating seal failure), visible drafts around frames, and windows that are hard to open or close. Which? (UK consumer advocacy group) reports that double glazing from the early 2000s typically had an E or F energy rating, meaning it loses heat three to four times faster than modern A-rated glass. Your heating system has to work much harder to compensate.
In cold Irish winters, that translates directly into higher bills. Upgrading to A-rated double glazing can reduce heating costs by 20-30%, according to SEAI (Ireland’s energy authority). For a typical 3-bed house with annual heating bills of €1,500–€2,000, that is a saving of €300–€600 every year.
An Irish homeowner with 20-year-old E-rated windows spending €1,800 a year on heating could recoup the cost of a full replacement (€3,500 for uPVC) within 6 to 10 years through energy savings alone — before factoring in the SEAI grant that can reduce the upfront cost by up to €2,400.
Repair vs replacement
Repair is cheaper short-term: fixing a seal or replacing a pane costs €100–€300 per window, versus €400+ for a full replacement. But Homebuilding & Renovating (UK home improvement magazine) points out that repairing 20-year-old frames is often a temporary fix — the frames themselves may be warped or degraded, and the thermal performance of the glass unit is fundamentally worse than what is available today.
The pattern: if three or more windows in your house show condensation or drafts, the economics tilt toward full replacement. If only one window has a minor issue, repair makes sense. New windows also add property value; estate agents surveyed by Which? (UK consumer advocacy group) estimate that a modern window set can increase a home’s sale price by 5-10%.
Can I get a grant for new windows in Ireland?
Yes — but with important conditions. On 2 March 2026, the Irish government announced a new SEAI grant specifically for energy-efficient windows and doors, part of a broader package that also increased attic and cavity wall insulation supports. gov.ie (Irish Department of Climate, Energy and the Environment) confirmed that the grant is available to homeowners who replace poorly performing windows and doors with energy-efficient alternatives, but it is tied to homes where the building fabric already meets a minimum performance standard.
SEAI grant amounts and eligibility
Industry guidance from Expert Windows (Irish glazing company) suggests the grant levels are:
- Apartments: up to €1,500
- Mid-terrace houses: up to €1,800
- Semi-detached/end-of-terrace: up to €3,000
- Detached houses: up to €4,000
The grant is only available through the National Home Energy Upgrade Scheme (One Stop Shop route) or the Better Energy Warmer Homes Scheme — not as a standalone DIY application. Homes must have been built before 2011, and all work must be carried out by SEAI (Ireland’s energy authority) registered contractors. A BER assessment is required before work begins.
The minister also announced that low-cost loans linked to these grants will require projects to achieve at least a 20% improvement in building energy performance. That means your window replacement might need to be part of a larger retrofit — attic insulation, wall insulation, or a heat pump upgrade — to unlock the full support package.
- Check eligibility: Confirm your home was built before 2011 and you meet income thresholds for the Warmer Homes Scheme.
- Book a BER assessment: You need a current Building Energy Rating before applying for the grant.
- Find SEAI-registered contractors: Only approved installers can carry out grant-qualifying work.
- Choose the grant route: Apply through a One Stop Shop or the Better Energy Warmer Homes Scheme.
- Submit quotes: Provide itemised quotes for the window replacement work.
- Install and verify: After installation, a final BER assessment confirms the energy improvement.

Expert perspective
The new suite of SEAI grants is designed to bring more homeowners into the energy-upgrade journey, especially first-time buyers of existing homes. The window and door supports are a key part of making older homes warmer and more efficient.
— SEAI spokesperson (Ireland’s energy authority)
For homeowners weighing the cost of window replacement, the key question is not just the upfront price but the total cost of ownership over 20-30 years. uPVC is cheapest to buy, but timber and aluminium require less frequent replacement over a long ownership period.
— Homebuilding & Renovating editor (UK home improvement magazine)
If your windows are more than 20 years old, the evidence strongly favours replacement over repair. The combination of SEAI grants (up to €4,000 for detached homes) and 20-30% energy bill savings means the decision has genuine financial teeth — not just comfort, but a measurable return on investment. For the typical Irish homeowner with a 3-bed semi-detached house and windows from the early 2000s, the choice is clear: replace now with A-rated uPVC or aluminium while the new SEAI support is available, or risk paying higher heating bills for another decade while grant levels remain uncertain.

For homeowners considering energy-efficient options, it’s worth comparing standard replacement prices with double glazed windows costs in Ireland to see the full cost-benefit picture.
Frequently asked questions
How long does window replacement take?
A typical full-house replacement for a 3-bed semi-detached takes 1-3 days, depending on the number of windows and whether any structural work (lintels, plastering) is needed. Single window replacements can be done in a few hours.
Do I need planning permission to replace windows in Ireland?
Generally, no — replacing like-for-like windows in a private house does not require planning permission. However, if you are in a protected structure or a designated Architectural Conservation Area, you may need permission. Check with your local authority.
What is the best double glazing brand?
There is no single “best” brand — it depends on your budget, style preference, and local availability. In Ireland, reputable brands include Munster Joinery, NorDan, Velfac, and Rationel. Always check for SEAI registration and warranty terms.
Can I replace just the glass or the whole frame?
You can replace just the glass unit (a “sealed unit replacement”) if the frame is in good condition — this costs €100–€300 per window. However, if the frame is warped, rotting, or more than 20 years old, replacing the whole window is usually better for energy efficiency.
How do I know if my windows are energy efficient?
Look for the energy rating label on the glass spacer bar. A-rated windows are best. Older windows (pre-2010) are typically E or F rated, meaning they lose much more heat. A BER assessor can give you an official rating.
Are triple-glazed windows worth the extra cost?
Triple glazing costs €100–€300 more per window and offers marginally better insulation. In mild Irish winters, the extra cost may take 15-20 years to recoup in energy savings. It is most worthwhile in exposed locations or for north-facing rooms.
What is the difference between double glazing and triple glazing?
Double glazing has two panes of glass with an insulating gas layer; triple glazing has three panes and two gas layers. Triple glazing is about 30% more energy efficient but costs more and the windows are heavier. For most Irish homes, high-quality double glazing (A-rated) is sufficient.
