Home Window Installation Cost

Comprehensive Guide to Home Window Installation Costs and Considerations

Home window installation is a crucial aspect of both new home construction and existing home renovations. The cost of installing new windows in your home can vary widely, influenced by factors such as the type of windows, the material they’re made from, the complexity of the installation, and additional features or customizations. Understanding these costs is essential for homeowners who are looking to improve energy efficiency, enhance the aesthetic appeal of their property, or increase its market value.



Types of Windows and Their Costs

UPVC Windows

UPVC windows, known for their durability and low maintenance, are a popular choice in the UK. Typically, the cost of a UPVC window ranges from £250 to £400, depending on the size and style. They are renowned for their excellent insulation properties, which reduce energy bills and enhance home comfort.

Wooden Windows

Wooden windows offer a classic, timeless look but are often more expensive, ranging from £400 to £700 per window. Their costs vary significantly based on the type of wood, with hardwood being more costly than softwood. Despite their higher price tag, wooden windows add a distinct charm and can significantly increase a property’s value.

Aluminium Windows

Aluminium windows, known for their sleek, modern appearance, cost approximately £400 to £600 per unit. They are highly durable, resistant to rust and corrosion, and require minimal upkeep. Their slim frames allow for larger panes of glass, maximising natural light and views.

Factors Influencing the Cost of Window Installation

Size and Number of Windows

The size and the number of windows being installed play a significant role in determining the overall cost. Larger windows or a greater number of windows naturally lead to higher expenses due to more materials and labour being required.

Window Style

The style of the window also impacts the cost. For example, sash windows are typically more expensive than casement windows due to their complex mechanisms and the traditional craftsmanship required.

Customisation and Additional Features

Customisation such as unique shapes, colours, or additional features like double glazing or security locks can add to the cost. Double glazing, for instance, is an essential feature for energy efficiency and noise reduction, but it does increase the price.

Labour Costs for Window Installation

The cost of labour for installing windows can vary based on several factors, including the complexity of the job, the location of your property, and the experience level of the installer. On average, the labour cost per window in the UK ranges from £100 to £300. It’s important to factor in the labour costs when budgeting for window installation, as these can significantly impact the overall expenses. When choosing an installer, it’s essential to balance cost with quality. Opting for the cheapest quote isn’t always the best decision, as it may compromise the quality of the installation. It’s advisable to get quotes from several contractors and check their credentials and customer reviews before making a decision.

Potential Extra Charges for Window Installation

Understanding Hidden Costs in Window Installation

Navigating the world of window installation can often bring unexpected costs, but being aware of these can help you budget more effectively. It’s not just about the window itself; there are several additional factors that can increase the overall price.

Removal and Disposal of Old Windows

One often overlooked aspect is the cost associated with removing and disposing of your old windows. This process requires time and effort, especially if you’re replacing old wooden or metal windows that might be fixed in place quite securely. The cost of removal and disposal can vary, but it’s an important consideration when planning your budget.

Structural Alterations

Another potential extra charge could arise if structural alterations are necessary. For instance, if you’re changing the size of your window openings or converting a window to a door, this will require additional labour and materials, thus increasing the cost.


In some cases, especially for installations above the ground floor, scaffolding may be needed. This is an additional safety measure for installers but adds to the overall cost of the project.

Moreover, the complexity of accessing higher floors can further extend the installation time and require additional labor, potentially increasing the total expense.

Cost-Effective Strategies for Window Installation

Choosing the Right Time of Year

Believe it or not, the time of year you choose to have your windows installed can impact the cost. Off-peak seasons, like late autumn or early winter, might offer more competitive pricing as demand for installations is typically lower.

Comparing Quotes

It’s always wise to get multiple quotes from different companies. This not only gives you a better understanding of the market rate but also puts you in a stronger position to negotiate.

Opting for Standard Window Styles and Sizes

Custom designs and sizes can significantly drive up costs. Choosing standard window styles and sizes can be a more budget-friendly option while still providing a fresh, new look for your home.

The Long-Term Value of Quality Window Installation

Energy Efficiency

Investing in quality window installation can offer significant savings in the long term. Good windows provide better insulation, reducing the need for excessive heating or cooling and thus cutting down on energy bills.

Increased Property Value

Quality window installations can also enhance the value of your property. They not only improve the aesthetic appeal but also the functional efficiency of the home, which is a significant factor for potential buyers.

Reduced Maintenance Costs

High-quality windows and professional installation can lead to reduced maintenance costs over time. Durable materials and proper installation can withstand the elements better and require fewer frequent repairs or replacements.

In conclusion, the cost of home window installation varies greatly based on the types of windows chosen, installation complexities, and additional features. By understanding these factors and exploring cost-effective strategies, homeowners can make informed decisions that balance aesthetic appeal with functional efficiency. Investing in quality window installation not only enhances the immediate look and feel of a home but also contributes to long-term savings and property value.
