Smart aluminium windows are a popular choice for homeowners and specifiers looking for high-performance, slim-profile glazing at a competitive price. But what should you actually expect to pay? This guide gives you an honest overview of Smart window pricing in the UK, including the key factors that influence costs and realistic price ranges for different systems.
Overview of Smart window prices
Smart windows are positioned in the mid-to-upper range of the UK aluminium window market. They’re not the cheapest windows available, low-cost fabricators offer aluminium windows at lower prices, but they are priced well below the premium European brands like Reynaers, and they offer demonstrably better performance than standard non-thermally-broken aluminium.
For the UK homeowner or specifier, Smart windows represent a sensible balance: genuine thermal and security performance, slim aesthetics, competitive pricing, and a reliable installer network.
Broad indicative price ranges (supply and installation, standard double glazing, UK labour rates):
| Window Type | Small (up to 1m²) | Medium (1-2m²) | Large (2m²+) |
|---|---|---|---|
| Smart Casement Window | £650-£950 | £900-£1,400 | £1,200-£1,800+ |
| Smart Tilt & Turn Window | £750-£1,100 | £1,050-£1,600 | £1,400-£2,000+ |
| Smart Fixed Frame Window | £550-£850 | £800-£1,200 | £1,100-£1,600+ |
These figures are for single windows, supply and installation, in standard RAL white or similar common colour, with standard argon-filled double glazing and warm-edge spacer.
For complete house window packages (replacing all windows), meaningful discounts are often available, and the per window cost typically reduces. Arc Glazing can provide package pricing for multi window projects.
Factors affecting price
Several variables have a material impact on Smart window pricing. Understanding these helps you budget accurately and have informed conversations with installers.
1. Window size
The most obvious factor. Larger windows require more aluminium, more glass, and more labour to fabricate and install. Beyond a certain size, structural considerations may also require thicker glass or reinforced frames, adding further cost.
2. Window type
Casement windows are the most commonly specified and tend to be the most competitively priced. Tilt and turn windows carry a modest premium due to more complex hardware. Fixed frames are often slightly cheaper than opening windows due to simpler hardware requirements.
3. Colour and finish
RAL white and standard silver are the most cost-effective colours. Non-standard RAL colours, textured finishes, and dual-colour options (different internal and external colours) typically add £80,£200 per window depending on size. Very dark colours (particularly black) are in consistently high demand and can carry a small premium with some fabricators.
4. Glazing specification
Standard argon-filled double glazing with warm-edge spacer is included in the prices above. Upgrades that increase cost include:
- Triple glazing, adds approximately £100-£300 per window depending on size
- Acoustic glass, varies by specification; asymmetric units (e.g. 6/16/8) typically add £80-£200 per window
- Solar control coatings, adds approximately £50-£150 per window
- Toughened or laminated glass, required in certain locations (low-level glazing, near stairs); adds £50-£150 per window
5. Installation complexity
Straightforward like-for-like replacements in accessible ground or first-floor locations are the least expensive to install. Complicating factors include:
- Scaffolding or access equipment requirements
- Structural lintels that need replacement
- Non-standard reveals or reveals requiring making-good after installation
- Third-floor or higher locations
- Heritage properties requiring careful protection of existing fabric
6. Location and installer
Labour costs vary meaningfully by region. London and South East England typically command higher installation rates than the Midlands or North. The fabricator and installer network for Smart means pricing can vary between different approved installers, it’s always worth getting more than one quote for larger projects.
Examples by system
New casement windows for a 3-bed house
A typical UK three-bedroom semi-detached house might have 8-12 windows of varying sizes. A full replacement in Smart aluminium casement windows in standard double glazing and a common RAL colour would typically cost in the region of £8,000-£18,000 fully installed, depending on window count, sizes, and the factors above.
Single large picture window
A fixed frame window used as a large feature element, say 1.8m wide by 1.4m high, in a contemporary extension would typically cost £1,100-£1,600 installed in standard specification.
Commercial office refurbishment
Window prices in commercial contexts are highly specification-dependent. For indicative purposes, Smart casement or tilt and turn windows in commercial projects often range from £800-£1,800 per unit installed, depending on specification, access, and project scale.
Supply & installation costs
It’s worth understanding how Smart window pricing breaks down:
Supply (fabrication cost): The cost of the aluminium profiles, glass unit, hardware, and fabrication labour typically represents 50-65% of the total installed cost for a standard window project.
Installation labour: Installation, including removal and disposal of existing windows, fitting the new frame, sealing, making good, and clearing up, typically represents 35-50% of the total cost.
For supply-only pricing (if you have your own installation team), Smart windows are available through Arc Glazing with prices varying by specification. Contact us for supply-only quotes on projects where you have your own fitting capability.
Value vs cost
Smart windows should be viewed as a long-term investment. Installed correctly, thermally broken aluminium windows require minimal maintenance and have a lifespan of 30-50 years. The energy savings from replacing poor performing glazing can meaningfully offset the capital cost over time, and the improvement in comfort, acoustic performance, and security has real value beyond the energy equation.
Compared to the major European premium brands, Smart offers equivalent regulatory-compliant performance at a 15-35% lower price. Compared to PVCu, Smart offers a more durable, aesthetically versatile product with equivalent or better thermal performance and a longer service life.
