How Much Do Palladian Windows Cost?

Palladian windows are a striking architectural feature in UK homes, inspired by the Renaissance designs of Andrea Palladio. Typically featuring a large central arched window flanked by two smaller rectangular sidelights, they exude elegance and grandeur. In 2025, with modern glazing and framing options, Palladian windows offer both aesthetic appeal and functionality. This guide explores their costs, benefits, and key factors to consider for installation or replacement in the UK.

Palladian windows often serve as a focal point—until they leak, fade, or lose their charm over time. Estimating their replacement cost can feel daunting due to their complex design and custom nature. Whether you’re enhancing a Georgian property or adding sophistication to a modern home, understanding the pricing is essential.

Typical Palladian Window Costs by Size

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

Total Width (mm)	Height (mm)	Glazing	Cost Range (uPVC)	Cost Range (Timber)
1800	1500	Double	£1,200-£1,800	£1,800-£2,400
2400	1800	Double	£1,500-£2,200	£2,200-£3,000
3000	2100	Double	£2,000-£2,800	£2,800-£3,800
3600	2400	Triple	£2,500-£3,500	£3,500-£4,800

In the UK, Palladian window costs typically range from £1,200 to £4,800, reflecting their bespoke design and larger scale. Their intricate structure and exposure to weather—rain, wind, and frost—mean they may need replacing over time. If yours are draughty or visually worn, a new set could revive their elegance.

Material Cost Comparison

Before committing to Palladian windows, it’s worth delving into the specifics. What’s the installation cost, and which material enhances your home’s look? Your choice balances budget, authenticity, and upkeep. Here’s a table comparing materials for a standard 2400mm x 1800mm Palladian window:

Material	Cost Range	Pros	Cons
uPVC	£1,500-£2,200	Cost-effective, low maintenance	Less authentic for period homes
Aluminium	£1,800-£2,600	Strong, slim frames, modern	Less traditional, less insulating
Timber	£2,200-£3,000	Classic beauty, good insulation	Requires regular maintenance

How much do Palladian windows really cost? Beyond size and material, custom features like arched glazing or decorative grilles can elevate the price. Timber is ideal for historical accuracy, uPVC offers affordability, and aluminium suits contemporary designs.

Factors Affecting Palladian Window Costs

Considering repairs instead? A cracked pane or warped frame might not mean a full replacement—repairs typically cost £150-£400, depending on damage. But if energy efficiency or grandeur is compromised, new windows could be the answer. Here’s what influences Palladian window costs:

Factor	Description	Impact on Cost
Size	Wider or taller designs increase materials	Adds £300-£500 per size jump
Glazing	Double vs. triple glazing	Triple glazing adds £200-£400
Material	uPVC, aluminium, timber	See material table
Labour	£300-£600 per window	Higher for bespoke installs
Custom Design	Arches, grilles, or sidelight details	£100-£300 extra

Repair or replace? If your Palladian window retains its structure and damage is minor, a repair might suffice. But if insulation is poor or the design looks dated, replacement can restore its majesty. A professional can guide your decision.

Additional Installation Costs

Choosing Palladian windows is about making a statement. Want historical charm or modern flair? Timber fits classic homes, uPVC keeps costs manageable, and aluminium offers sleek lines. Here’s a breakdown of extra costs:

Expense	Typical Cost	Notes
Removal of Old Window	£100-£250	Depends on size and state
Structural Support	£300-£800	Lintel or frame reinforcement
Building Regulations	£150-£250	FENSA certification
Finishing (e.g., plastering)	£150-£300	Interior/exterior touch-ups

Materials shape cost and care—uPVC is low-maintenance, timber requires upkeep for its elegance, and aluminium offers durability. Glazing upgrades like triple panes or low-e coatings add £200-£400, enhancing efficiency. A typical installation might total £1,800-£5,000 with extras.

Return on Investment (ROI)

Palladian windows elevate aesthetics and value—here’s how they pay off:

Benefit	Estimated Savings/Value	Timeframe
Energy Savings	£100-£250/year	Ongoing with efficient glazing
Property Value Increase	3-6% of home value	Upon resale
Payback Period	12-18 years	Based on savings and value

Palladian window costs in 2025 range from £1,200 for a modest uPVC unit to £4,800 for a large timber one.
