How Much Do uPVC Windows Cost?

uPVC windows, made from unplasticised polyvinyl chloride, are a staple in UK homes, prized for their affordability, durability, and low maintenance. Available in styles like casement, sash, or tilt-and-turn, they offer versatility and excellent insulation with double or triple glazing options. In 2025, with advancements in energy efficiency and design, uPVC windows remain a top choice for cost-conscious homeowners. This guide explores their costs, benefits, and key factors to consider for installation or replacement in the UK.

uPVC windows often blend seamlessly into daily life—until they fade, warp, or fail to seal properly. Estimating their replacement cost involves sorting through variables like size, style, and glazing. Whether you’re upgrading a modern flat or refreshing a family home, understanding the pricing is essential.

Typical uPVC Window Costs by Size and Style

The cost of uPVC windows varies by size, style, and glazing type. Below is a table showing typical dimensions and cost ranges in the UK for 2025 (including standard installation):

Width (mm)	Height (mm)	Style	Cost Range (Double Glazed)	Cost Range (Triple Glazed)

In the UK, uPVC window costs typically range from £200 to £900 per window, depending on size, style, and glazing. Their robust construction resists weathering from rain, wind, and frost, but older units may yellow or crack over time. If yours are draughty or discoloured, replacement could restore efficiency and looks.

uPVC Window Style Cost Comparison

Before choosing uPVC windows, it’s worth comparing styles. What’s the installation cost, and which design fits your home? Your decision balances budget, functionality, and aesthetics. Here’s a table comparing styles for a standard 900mm x 1200mm uPVC window (double glazed):

Style	Cost Range	Pros	Cons
Casement	£300-£450	Simple, widely compatible	Basic design
Sash	£400-£550	Traditional look, good ventilation	Slightly pricier
Tilt-and-Turn	£450-£600	Versatile, easy to clean	Higher cost, bulkier frame

How much do uPVC windows really cost? Beyond size and style, extras like triple glazing, custom colours, or enhanced security can increase the price. Casement is the budget-friendly standard, sash mimics heritage charm, and tilt-and-turn offers modern flexibility.

Factors Affecting uPVC Window Costs

Considering repairs instead? A faulty lock or cracked seal might not need a full replacement—repairs typically cost £80-£200, depending on the issue. But if insulation or operation is poor, new windows could be the smarter choice. Here’s what drives uPVC window costs:

Factor	Description	Impact on Cost
Size	Larger windows require more material	Adds £100-£200 per size jump
Glazing	Double vs. triple glazing	Triple glazing adds £50-£150
Style	Casement, sash, tilt-and-turn	See style table
Labour	£100-£200 per window	Higher in urban areas
Extras	Colours, security locks	£20-£100 per feature

Repair or replace? If your uPVC windows function well and damage is small, a repair might save cash. But if drafts, fading, or stiffness are issues, replacement offers better efficiency and longevity. A professional can help you weigh the options.

Additional Installation Costs

Choosing uPVC windows is about value and ease. Want affordability or energy savings? Casement keeps it simple, sash adds style, and tilt-and-turn boosts functionality. Here’s a breakdown of extra costs:

Expense	Typical Cost	Notes
Removal of Old Window	£50-£150	Depends on condition
Scaffolding	£200-£400	For upper floors
Building Regulations	£100-£150	FENSA certification
Finishing (e.g., trim)	£20-£50 per window	Optional aesthetic work

uPVC’s durability means low upkeep, but extras like woodgrain finishes or high-security locks add £20-£100 per window. Glazing upgrades like triple panes or low-e coatings add £50-£150, enhancing efficiency. A typical replacement might total £350-£1,100 with extras.

Return on Investment (ROI)

Benefit	Estimated Savings/Value	Timeframe
Energy Savings	£75-£200/year	Ongoing with good glazing
