Cost-effective uPVC windows and replacement windows fitted near Heathfield

If you are looking for cost-effective and energy-efficient windows in Heathfield, Uckfield, or Buxted, then we can provide a whole host of uPVC windows solutions for your needs.

uPVC has become the window material of choice for affordable windows because it is durable, energy-efficient, and secure. Our uPVC windows offer a maintenance-free solution and are extremely energy efficient so you can save money on your energy bills.

We supply and fit Kommerling’s 070 Gold and C70 Gold ranges and the Rehau Total70 range. Designed by some of Europe's best engineers, these windows combine style, thermal efficiency, sound insulation, boosted security and ease of use. The design is modern and clean and low line gaskets allow for slimmer sightlines and more visible glass and fantastic views

Kommerling windows also boast the Greenline label which means that no lead has been used to stabilise the uPVC. Instead, an environmentally friendly calcium zinc-based stabiliser has been utilised. When each window is at the end of its lifecycle, all the old window components are reused to make new ones making it one of the most sustainable choices. All our uPVC windows are available in an ever-increasing range of colours and woodgrain finishes.

We can supply and fit:

  • uPVC casement windows
  • uPVC sash windows

Very impressed with the service provided, from the initial consultation to the final installation, everything was dealt in a very professional way.


Amazing job, I really recommend Unique Windows (London). They fitted the new doors and removed the old ones, left the place looking as it was and this was all done within a week of getting the quote, amazingly fast and reliable service with quality trades people.


We had changed all the windows in the house. They look very smart and elegant. So much that I only had praises from my neighbours and friends. Unique windows did a fantastic job at a very competitive price. Very tidy, quick and efficient. Overall, an excellent customer service. I have already recommended Unique Windows to my neighbours and friends, and I believe they have contact this company already. I will certainly use them again.


Very pleased with our new doors and windows. The fitting is excellent and Unique Windows were able to accommodate a couple of non-standard requests. Price was fair and communication clear. I would use them again in future for the remainder of the windows on our house and recommend.
