Questions people ask
How much does a single new window cost?
For one standard uPVC casement window, you might expect to pay between £300 and £800. This estimate usually includes both the window unit and its professional installation.
Will new windows save me money?
Yes, they certainly can. Low-E double glazing significantly improves your home's insulation, which can reduce your heating bills over time. It's an investment in your comfort and your wallet.
How long does installation take?
Installing new windows is usually quite quick. A typical home might see all its windows replaced within one to three days, depending on the number and complexity of the units.
What is low-E glass?
Low-E stands for low-emissivity. It's a special coating on the glass that reflects heat back into your room during winter and keeps excess heat out in summer. This makes your home more energy efficient.
Do I need planning permission for new windows?
Most window replacements, as long as they are similar in appearance to the originals, do not need planning permission. However, it's always wise to check with your local council, especially if your home is listed or in a conservation area.
