Whether you are upgrading from single glazing to double glazing or simply replacing your old uPVC windows with new ones, getting modern uPVC windows fitted in 2026 can make a huge difference to your energy bills and comfort at home.
New windows have great potential to improve your home, but it is important to understand that there are many options to consider when choosing. We highly recommend consulting one of our product experts to guide you through the wealth of information available — including upgrades for insulation, security, ventilation, colours, and your window sills.
To make it easier to compare double glazing quotes, we offer a Price Match Promise, where we match like-for-like quotes with the same specifications (Price Match Promise terms apply).

As mentioned above, there are quite a few factors that impact the cost of your new windows. As a general rule of thumb, you can budget from £500 for a small casement window with no additional specifications (plain white), up to £1,300 or more per window for more complex sash and case windows with extensive specifications. Essentially, the cost comes down to:

• Like-for-like replacement — Are you replacing your windows with the same type and size?
• Security upgrades — Do you require toughened glass or PAS24 certified windows?
• Performance glazing — Do your windows need additional insulation?
• Window style — Casement, Tilt & Turn, or Sash & Case
• Colour & finish — Standard white, or something like anthracite, oak, or burgundy?
• Additional specifications — Any other bespoke requirements

We also offer flexible finance options for windows to help with budgeting, so you can get the windows you want without compromise if needed.
