Planning a window replacement project means thinking about costs. For homeowners across Cheshire, understanding what you might pay – and why – helps you make informed decisions about your property. At Northwich Glass, we’ve been helping local families with double glazing since 1959, and we know that transparent information about window costs matters.
Window replacement is one of those home improvements that can feel daunting because prices vary considerably. You might be replacing old windows that are letting in draughts and pushing up your energy bills. Perhaps you’re renovating and want to improve your home’s appearance. Or maybe you’ve noticed condensation, noise, or other issues that signal it’s time for new windows. Whatever your reason, knowing what influences the total cost helps you budget correctly and make the right choice for your home.
The good news is that modern replacement windows deliver real value. They reduce heat loss, cut down on noise reduction issues, improve security, and often pay for themselves over time through lower energy bills.
What Influences Window Replacement Cost?
Several key factors affect what you’ll pay for your window replacement project. None of these elements works in isolation – they all interact to determine your final price.
Window Style and Design
The style of window you choose significantly impacts cost. Standard casement windows, the most common type in UK homes, are typically the most affordable option. They’re straightforward to manufacture and install, which keeps costs down.
More complex designs require additional materials and installation time. Bay & bow windows, for example, project outward from your home and involve more intricate fitting. Sliding sash windows include counterbalance mechanisms that add to manufacturing complexity. These design differences directly affect the price you’ll pay.
Frame Material
The frame material is another major cost factor. uPVC frames are generally the most budget-friendly option. They’re lightweight, durable, require minimal regular maintenance, and provide excellent thermal efficiency. They’ve become the default choice for many homeowners across Northwich and Cheshire.
Aluminium frames cost more but offer distinct advantages. They’re incredibly strong, allowing for slimmer sight lines and larger glass areas. Aluminium windows have exceptional durability and longevity; they can last 30-40 years or more. For modern properties or where aesthetic appeal is a priority, many homeowners find the additional investment worthwhile.
Size and Number of Windows
Window size matters considerably. A small bathroom window costs far less than a large living room window simply because of the materials and labour involved. The size of the window directly affects the amount of glass, frame material, and installation time required.
The number of windows you’re replacing also influences pricing. Replacing a single window is often more expensive per unit than replacing multiple windows at once. When we carry out a whole-house project, the efficiency of completing everything together, from surveying to installation, means better value overall.
Installation Complexity
Some installations are straightforward, while others present challenges. Ground floor windows are generally simpler to access than upper floors, where scaffolding or specialist equipment might be needed. Properties with unusual wall construction, listed building requirements, or difficult access can increase installation costs.
Window Options at Northwich Glass
At Northwich Glass, we offer a comprehensive range of windows suitable for traditional and modern homes across Cheshire. Understanding your options helps you balance the cost of new windows against the features that matter to you.
Casement Windows
Casement windows are the UK’s most popular choice. They’re hinged at the side and open outward, providing excellent ventilation and easy cleaning from inside. They work well with both modern and traditional properties and deliver reliable performance year after year.
Flush Sash Windows
Flush sash windows sit flush with the outer frame when closed, creating a smooth, elegant appearance. They’re designed to replicate traditional timber windows, making them an excellent choice for period properties or conservation areas in Northwich while delivering modern double glazing performance.
Sliding Sash Windows
Sliding sash windows open vertically rather than outward. They’re a classic design that suits older properties beautifully while incorporating contemporary thermal efficiency and security features.
Bay & Bow Windows
Bay & bow windows extend outward from your property, creating additional interior space and flooding rooms with natural light. They’re a stunning architectural feature that adds character to any home. While they represent a larger investment, they also significantly boost aesthetic appeal and property value.
Tilt & Turn Windows
Tilt & turn windows offer versatile operation – they tilt inward at the top for secure ventilation or swing fully inward for easy cleaning. They’re particularly popular for upstairs rooms and provide excellent security when in the tilted position.
Material Choices: uPVC and Aluminium
All our window styles are available in both uPVC and aluminium. uPVC windows delivers excellent value, requires virtually no maintenance, and provides outstanding energy efficiency. Aluminium offers superior strength, slimmer frames, and a contemporary appearance that many homeowners prefer for modern properties.
What Might You Pay?
Providing the exact cost of replacement windows is difficult because every home and project is different. However, we can offer some guidance and average costs on what homeowners in Northwich and Cheshire typically invest in window replacement.
For a standard casement window in uPVC, including professional installation, homeowners might expect to pay somewhere in the region of £400-£800 per window, depending on size and specifications. Aluminium windows typically have a higher upfront cost, often from £600-£1,200 or more per window, reflecting the premium material and manufacturing processes.
More complex styles like sliding sash or bay windows will cost more – sometimes significantly more – due to their design and installation requirements.
Making the Right Investment
Window replacement cost represents a significant investment, but it delivers returns through reduced energy bills, improved comfort, better security, and increased property value. Modern windows perform dramatically better than older alternatives, reducing heat loss and creating more comfortable living spaces.

Frequently Asked Questions
How can I reduce my window replacement costs?
The most effective way to manage costs is to replace multiple windows at once rather than individually. This approach spreads the surveying and installation efficiency across several windows, reducing the per-window price.
Do you take away the old windows?
Yes. We remove and responsibly dispose of all old frames and glass as part of the window installation service, so you don’t have to worry about waste.
How quickly will new windows pay for themselves through energy savings?
This depends on several factors, including your current windows’ condition, your home’s heating costs, and the type of glazing or type of window you choose. Generally, homeowners see better insulation and reductions in energy bills immediately after installation.
