Window Replacement Cost Guide
The cost of replacement windows depends on frame material, glazing specification, size and installation complexity. As a rule of thumb, a standard uPVC window (130 × 130 cm, double-glazed) costs €350–550 for the window alone. Premium timber-aluminium frames with triple glazing range from €800–1,400.
| Material | Window (supply only) | U-value (W/m²K) | Lifespan |
|---|---|---|---|
| uPVC | €250–450 | 0.9–1.3 | 25–40 yrs |
| Timber | €400–700 | 0.8–1.2 | 30–50 yrs |
| Aluminium | €500–900 | 1.0–1.4 | 40–60 yrs |
| Timber-Aluminium | €700–1,200 | 0.7–1.0 | 40–60 yrs |
Installation Costs Breakdown
| Installation labour (per window) | €100–250 |
| Old window removal | €50–100 |
| Disposal | €30–60 |
| Total per window (uPVC, standard) | €450–700 |
Pro tip: Triple glazing almost always pays off
The upgrade from double to triple glazing costs only €30–60 per window, but delivers 10–15% lower heating bills. On a 10-window project you spend €300–600 more upfront but save €200–400 per year on energy. It also qualifies for most government energy efficiency grants.
Frequently asked questions
How much does a replacement window cost?↓
A standard uPVC double-glazed window (approx. 130 × 130 cm / 51 × 51 in) costs €450–700 fully installed, including removal of the old window. Triple-glazed timber-aluminium windows run €900–1,500.
Double glazing or triple glazing?↓
Triple glazing is almost always worth the extra cost — typically €30–60 more per window, but 10–15% less heating energy. Triple glazing is also required for most government energy efficiency grants.
Which frame material is best?↓
uPVC is the most cost-effective (25–40 year lifespan). Timber offers the best insulation but needs periodic maintenance. Aluminium is very durable and low-maintenance. Timber-aluminium composite is the premium option with a 40–60 year lifespan.
How long does window installation take?↓
A typical 10-window replacement project takes one to two days for an experienced team of two installers.
Are these prices in USD or EUR?↓
The calculator uses European (EUR/€) prices, based on current market rates in Germany and Austria. For US pricing, multiply by approximately 1.05–1.2 depending on your region.
