Breaking Down uPVC Sash Window Costs

The cost of uPVC sash windows varies widely, determined by several factors influencing the overall price of these fashionable and energy-efficient windows.

From size and glazing to colours and finishes, each element has its role in the overall cost.

Size of uPVC Sash Windows

When considering the installation of new windows, it’s essential to factor in the cost of uPVC sash windows, which is directly influenced by their size.

Larger windows require more material and thus come with a heftier price tag.

For example, a 500mm x 500mm window costs between £520 and £625, while a larger 1000mm x 500mm averages £600 to £720.

Double Glazing and Energy Efficiency

Double glazing is a cost-effective and energy-saving feature for uPVC sash windows.

Double-glazed sash windows, which utilise double-glazed units, are less expensive than triple-glazed options, with the latter being around 35% more costly.

Additionally, double glazing can lower heating expenses by up to 50% compared to single glazing, meaning these windows are a financially smart choice for the long term.

Colours and Finishes of Sash Windows

Colour and finish options add a personal touch to your uPVC sash windows but also influence the final cost.

Some options to consider are:

  • Standard white uPVC: the most budget-friendly choice
  • Coloured finishes: add more character to your property
  • Textured finishes: provide a unique look
  • Wood effects: create an elegant and traditional appearance

Remember that these choices, especially the more elaborate wood effects, can increase the overall cost.

uPVC Sash Window Lifespan

uPVC sash windows provide an excellent return on investment.

With an average lifespan of about 35 years, they are a long-term solution for homeowners.

In addition, their resistance to rot and decay and their ability to withstand harsh weather conditions without warping or peeling make them a practical and cost-effective choice.

Longevity and Replacement

Factors such as environmental conditions can affect the longevity of uPVC sash windows. For instance, windows in coastal areas may age faster due to salt spray and strong winds.

However, signs of wear, such as reduced energy efficiency, draughtiness, and visible physical deterioration, indicate that windows may need to be checked and replaced.

Maintenance to Keep Low Costs

A significant benefit of uPVC sash windows is their minimal maintenance requirements. In contrast to traditional timber windows, uPVC windows don’t require frequent painting or refurbishment.

Regular cleaning and occasional lubrication of window locks and hinges are all it takes to keep your uPVC sash windows in top shape.

Installation Insights

Several factors can influence the cost and duration of uPVC sash window installation. These factors include:

  • Window accessibility
  • Pre-existing structural damage
  • Ease of access to the building
  • Structural complexities of the building
  • Number of windows to be installed

Labour costs may be higher if there are accessibility issues or pre-existing structural damage.

The time taken for installation will also vary depending on these factors.

Professional Installation vs DIY Cost

Despite seeming like a budget-friendly alternative, installing uPVC sash windows yourself is not as straightforward as it appears. The process requires specific tools, materials, and a solid understanding of window installation techniques.

In contrast, professional installation eliminates risks associated with inexperienced DIY attempts, ensuring safety, correct fitting, and optimal performance.

Customisation Pricing

The ability to customise is a significant feature of uPVC sash windows.

Choosing from various coloured sash windows and finishes allows homeowners to personalise their windows to suit their property’s aesthetic.

However, these customisation options can affect the overall cost of uPVC sash windows, with unique colours and finishes typically costing more.

Enhancing Property Value with uPVC Sash Windows

Investing in uPVC sash windows can significantly enhance your property’s value. Their modern performance and visually appealing designs can make your property more attractive, particularly in high-demand regions.

These windows increase a property’s market value by adding heritage charm and meshing aesthetic appeal with modern functionalities.

Aesthetic Appeal and Market Attractiveness

The visual appeal of uPVC sash windows can significantly affect a property’s attractiveness and, consequently, its market value.

These windows can be a deciding factor for many potential buyers, particularly those who value energy efficiency and updated features.

Moreover, the condition and style of windows significantly contribute to a property's overall desirability and market value.

Energy Savings

uPVC sash windows also excel in energy efficiency. Their thermal efficient design keeps homes warmer for longer periods, reducing the energy consumption required for heating.

This reduces heating costs and enhances the property’s value by making it more energy-efficient and attractive to potential buyers.

uPVC Sash Window Cost vs Other Styles

Offering a balance between affordability and performance, uPVC sash windows are a cost-effective alternative to other window styles, including replacement sash windows.

For instance, they are typically more budget-friendly than traditional timber sash windows while providing modern performance and an authentic aesthetic.

One reason for this affordability is using sash window materials like uPVC.

uPVC vs Timber Cost

In terms of cost-effectiveness, uPVC windows outperform timber sash windows.

Over 30 years, including initial installation and maintenance, uPVC sash windows potentially cost less than half as much as timber windows.

And let’s not forget, they require less upkeep and never need to be repainted, adding to their practicality.

Sliding Sash vs Casement Windows Costs

Vertical sliding sash windows and casement windows can also have budget implications. Sliding sash windows generally cost more due to their complex opening mechanisms and the skill required for their installation.

On the other hand, casement windows, known for their affordability and popularity, are quicker, easier, and more economical to install.


In summary, uPVC sash windows offer a fusion of aesthetic appeal, energy efficiency, and cost-effectiveness.

By making an informed decision about the size, colour, finish, and installation method, you can leverage the benefits of these windows to enhance your property’s value and reduce energy costs.

And remember, while the initial cost might seem significant, the long-term savings and the boost to your property’s market value make uPVC sash windows a worthwhile investment.
