How Much Do Single Hung Windows Cost?

Single hung windows are a practical and budget-friendly option for UK homeowners, featuring a fixed top sash and a bottom sash that slides upward for ventilation. Simpler than their double hung counterparts, they offer a traditional look with straightforward functionality. In 2025, with modern glazing and frame options, single hung windows remain a cost-effective choice for many properties. This guide explores their costs, benefits, and key factors to consider for installation or replacement in the UK.

Single hung windows often go unnoticed in everyday life—until they stick, crack, or fail to insulate properly. Estimating their replacement cost involves sorting through variables like size, material, and labour charges. Whether you’re refreshing a small space or seeking an economical upgrade, understanding the price breakdown is essential.

Typical Single Hung Window Costs by Size

The cost of single hung windows varies by size 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)	Glazing	Cost Range (uPVC)	Cost Range (Aluminium)
600	900	Double	£200-£350	£300-£450
900	1200	Double	£300-£450	£400-£550
1200	1500	Double	£400-£600	£500-£700
1200	1800	Triple	£500-£750	£600-£850

In the UK, single hung window costs typically range from £200 to £850 per window, depending on size, material, and glazing. Their simplicity keeps prices lower than double hung windows, but they still face wear from rain, wind, and cold over time. If yours are hard to slide or letting in drafts, replacement might be worth considering.

Material Cost Comparison

Before choosing single hung windows, it’s smart to research your options. What’s the installation cost, and which material fits your needs? Your decision balances budget, maintenance, and style preferences. Here’s a table comparing materials for a standard 900mm x 1200mm single hung window:

Material	Cost Range	Pros	Cons
uPVC	£300-£450	Affordable, low maintenance	Basic look
Aluminium	£400-£550	Durable, slim frames, modern	Less insulating, pricier
Timber	£550-£800	Classic appeal, good insulation	Requires upkeep

How much do single hung windows really cost? Beyond size and material, extras like triple glazing or custom finishes can push the price up. uPVC is the budget winner, timber adds a heritage touch, and aluminium offers a sleek, contemporary vibe.

Factors Affecting Single Hung Window Costs

Considering repairs instead? A stuck sash or cracked pane might not demand a full replacement—repairs typically cost £80-£200, depending on the damage. But if insulation or ease of use is lacking, new windows might be the better choice. Here’s what influences single hung window costs:

Factor	Description	Impact on Cost
Size	Larger windows need more materials	Adds £100-£200 per size increase
Glazing	Double vs. triple glazing	Triple glazing adds £50-£150
Material	uPVC, aluminium, timber	See material table
Labour	£100-£200 per window	Higher in urban areas
Sash Mechanism	Springs or weights for sliding	£20-£80 for upgrades

Repair or replace? If your single hung window slides well and damage is small, a repair could save cash. But if drafts or stiff operation are issues, replacement offers better efficiency and longevity. A pro can help you weigh the options.

Additional Installation Costs

Choosing single hung windows is about simplicity and savings. Want basic ventilation or a timeless style? uPVC keeps costs down, timber adds character, and aluminium brings a modern edge. 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

Materials impact cost and care—uPVC is hassle-free, timber needs upkeep for its charm, and aluminium offers strength. Glazing upgrades like triple panes or low-e coatings add £50-£150, improving efficiency. A typical replacement might total £350-£1,000 per window with extras.

Return on Investment (ROI)

Single hung windows offer practical benefits and modest value—here’s how they pay off:

Benefit	Estimated Savings/Value	Timeframe
Energy Savings	£50-£150/year	Ongoing with good glazing
Property Value Increase	1-2% of home value	Upon resale
Payback Period	10-15 years	Based on savings and value
