What is uPVC and why is it so popular?

uPVC, or unplasticised polyvinyl chloride, is a rigid plastic material widely used in window frames. Its popularity stems from its durability, energy efficiency, and cost-effectiveness. uPVC windows offer excellent insulation, require minimal maintenance, and are available in a variety of styles and colours to suit any property.

What impacts the cost of uPVC windows?

Several factors influence the price of uPVC windows:

1. Window style: Different styles, such as casement, sliding sash, or tilt and turn, vary in price.
2. Window size: Larger windows generally cost more.
3. Frame type: Standard white uPVC is usually the most affordable, while woodgrain effects or coloured options increase the price.
4. Glass specifications: Standard double glazing, triple glazing, or speciality glass like solar control can affect the cost.
5. Regional differences: Prices may vary depending on your location in the UK.

How much do uPVC windows cost?

Based on information from Checkatrade, here’s a breakdown of uPVC window costs by style:

Casement Windows

Casement windows are the most common and typically the most affordable option. Prices range from £300 to £550 per window, depending on size and specifications.

Sash Windows

Sash windows offer a classic aesthetic and are generally more expensive than casement windows. Expect to pay between £520 and £800 per window, with wood effect finishes at the higher end of the range.

Tilt and Turn Windows

Tilt and turn windows offer excellent ventilation and security. Prices range from £490 to £695 for standard uPVC, while woodgrain effect options can cost between £580 and £810.

Bay Windows

Bay windows are more complex and thus more expensive. Prices can range from £1,000 to £2,400, depending on the number of sections and specifications.

It’s important to note that these prices include both the window and installation costs. The total cost of your project will depend on the number of windows, additional features, and any extra work required.

Factors affecting uPVC window prices:

1. Frame material: While uPVC is generally the most cost-effective option, alternatives like aluminium windows or wooden windows with timber frames can be considerably more expensive.
2. Type of glass: The choice between new double glazing and triple glazing impacts both the cost and energy efficiency. Triple glazing offers better insulation but comes at a higher average cost.
3. Window size and style: Non-standard sizes or unique architectural styles may require custom manufacturing, increasing the average price.
4. Energy efficiency: High-performance glass and frames that provide better insulation and reduce heat loss can increase upfront costs but lead to long-term savings on energy bills.
5. Additional features: Options like trickle vents, external cills, or speciality hardware can add to the overall cost.
6. Colour and finish: As mentioned earlier, coloured uPVC or woodgrain effects are typically more expensive than standard white uPVC.
7. Installation complexity: Factors such as ease of access, the condition of existing frames, and whether you’re opting for replacement windows or new installations in different openings can affect labour costs.
8. Regional variations: Prices can vary across different areas of the UK, with London and the South East often seeing higher costs.
9. Brand and quality: Different manufacturers offer varying levels of quality, guarantees, and price points.

uPVC windows can be finished in a variety of colours.

Making an informed decision:

When considering uPVC windows, it’s essential to look beyond just the initial cost. Factor in:

• Energy savings: Better insulation from quality double or triple glazing can significantly reduce heating bills over time.
• Maintenance costs: uPVC requires minimal upkeep compared to materials like timber.
• Longevity: Many uPVC windows come with a 10-year guarantee, offering peace of mind.
• Property value: New, energy-efficient windows can increase your home’s value and appeal to potential buyers.
• Noise reduction: Good quality uPVC windows can also help with soundproofing.
