Rough Cost for New Windows UK
A home’s windows are essential to improving its exterior appeal, energy efficiency, and general comfort. One of the first concerns that probably crosses your mind when thinking about replacing your old windows with new ones is how much it will cost. New window prices can vary widely depending on the type, material, size, and installation needs of the windows.
We’ll give you a breakdown of the typical cost of new windows in this article, so you can plan your home renovation project with confidence.
Factors Affecting Window Cost
Window Type
There are many different types of windows to pick from, such as casement windows, sash windows, tilt and turn windows, and more. Each variety has its own design and value, which can affect the price.
Material
The material you choose for your windows will have a significant impact on their cost. uPVC (unplasticized polyvinyl chloride), wood, aluminium, and composite materials are all common materials. While uPVC windows are normally less expensive, wooden windows are more expensive due to their aesthetic appeal and natural insulating characteristics.
Glazing
The number of panes and kind of glass you select will affect the cost and energy efficiency of your windows. Double glazing is the industry standard for energy-efficient windows, but triple glazing provides even more insulation at a higher cost.
Size and Number of Windows
Larger windows and more windows will automatically raise the overall cost. Additional fees may apply for custom sizes or forms.
Extras and Features
Additional features such as decorative grilles, integrated blinds, security enhancements, and special finishes can add to the cost but can also enhance the value and functionality of your windows.
Installation Complexity
The ease of installation can affect the labour cost. Replacing windows in hard-to-reach places or within historical buildings might require more effort and resources.
Rough Cost Estimates
Windows can vary wildly in prices depending on your needs. Of course, the more windows you need the more expensive the job will be but there are usually discounts or special offers when you bulk buy, so make sure to look out for those! Per window you are looking to pay between £600 – £3,600, with the least expensive choice being a standard white uPVC casement window and the upper regions will be for something more specialised, perhaps a window for a listed building. Other factors that can affect the price per window include size, glazing style, make and model.
uPVC Window Price Guide*:
uPVC Casement Windows: £600-£1,800
Sash Window: 50% more than a casement window
Tilt and Turn Window: 25% more than a casement window
Bay Window: 150% more than a casement window
Aluminium Frame: 25% more than uPVC
Timber Frame: 50% more than uPVC
Wooden Window Price Guide
Single Glazed Wooden Windows: £157 to £650
Style and size affect pricing, but you can cut costs by looking about and buying the windows and frames separately. If it does not go against the regulations of your property we strongly recommend to upgrade your windows to double glazed. They are most cost effective in the long run by cutting your energy bills down and they help stop so much condensation and the ability for damp spots and mould to grow.
The cost of a wooden double-glazed window is often double that of a single sash window, which can cost up to £1,300.
These are only ballpark figures; the actual price may change depending on your unique needs and the area you’re in. To get a more realistic idea of the price for your project, it is essential to get quotes from multiple suppliers and installers.
Benefits of Upgrading your Windows
Investing in new windows can bring numerous benefits to your home, from improved aesthetics to enhanced energy efficiency. While the cost of new windows in the UK can vary significantly based on factors like window type, material, glazing, and size, having a rough estimate can help you plan your budget effectively.
To get the most accurate pricing for your project, it’s recommended to consult with reputable window suppliers and installers who can provide tailored quotes based on your needs. With the right windows in place, your home can enjoy enhanced comfort, aesthetics, and value for years to come.
