All installations are carried out by our own directly employed installation teams, not subcontractors. Our fitters are highly trained craftsmen who take the time to complete each job to a high standard, ensuring your new windows are fitted correctly and perform as designed.

How much do uPVC windows cost?

Our uPVC window prices depend on the style, size, glazing and specification you choose. As a guide, our uPVC windows start from around £300 for chamfered and sculptured sash windows, £375 for flush sash windows, £500 for evolution flush sash windows and £600 for vertical sliding sash windows.

Aluminium vs uPVC Windows and Doors – What’s the Difference?

Both aluminium and uPVC windows and doors are excellent options, and the right choice will depend on your home, style preferences, and budget.

uPVC remains a popular choice for many homeowners due to its affordability, energy efficiency, and low maintenance, making it a practical and reliable solution.

Aluminium, on the other hand, is often chosen for its sleek, modern appearance and enhanced structural strength.

With aluminium, you can benefit from:

• Slimmer frames and larger glass areas
• A contemporary, architectural finish
• Strong, durable construction
• Ideal for larger openings such as bifold and sliding doors

Whether you choose uPVC or aluminium, our team will help you find the best solution to suit your home and requirements
