High-Quality Windows In Uxbridge

Manufactured and rigorously tested to withstand the ever-changing UK weather, our range of windows are all professionally installed to keep you safe and comfortable at home.

Our windows are available with a variety of glass sealed unit configurations and are certified up to ‘A’ Rating (the industry maximum) by the British Fenestration Rating Council’s Energy Rating Scheme. With a coverage area spanning wide from our home in Uxbridge, we offer window installation and replacements across Hillingdon, Maidenhead and even as far as High Wycombe.

As a family-run business since 1979 we are more than experienced in replacing broken and obsolete windows. We offer a professional service with a versatile range of replacement options to suit your budget, home and desired style.




We are able to offer replacement windows with the high-security TRICEPT PVC-u system and also the Beaufort aluminium suite. Both products are covered by a full IWA Insurance backed 10 year guarantee for added peace of mind.

No matter which option for upgrading your windows you chose you can be sure all our options are manufactured to the latest Building Regulation requirements. Sovereign is registered with FENSA, the regulatory authority set up to monitor and record window and door installations.

We are aware that many customers do not wish, or are wary of a representative calling at their home. That’s why we offer a quotation service over the telephone; all that’s needed is the approximate window or door sizes.

To add even more flexibility to our customers we have recently added a remote quoting option. Using the latest in sophisticated software we can now tweak sizes, styles as you like and even show you what your new windows will look like. With this we can produce multiple quotes, allowing you to explore our full range of frame options. 

As a family-run business we are never about the hard sale, we have no commission or brand affiliations so all work carried out will be fair and all advice given is to solely benefit you, our customer. For example when quoting for a single window we will always try to conduct a window repair where possible to keep your costs as low as possible. 

We pride ourselves on our customer first approach in every aspect of what we do, always ensuring that every possibility is met to enhance our service and the products that we provide to give the most competitive prices.

Sovereign’s Double Glazed Window Range

What Types Of Windows Can You Install?

With such a wide client base, extending beyond our home in Uxbridge, such as our expert offering of double glazing in Slough, we cater to a range of styles depending on your home. From new builds protruding with a contemporary aesthetic to the more traditional style homes that have long stood the test of time, at Sovereign Windows, we offer the perfect combination of window style and material that will fit effortlessly within any home. 

Styles Of Window We Install Include:

Sash Windows – Most popular in traditional homes, we can install a range of sash windows spending on the style of your home. This includes Edwardian, Georgian and Victorian, all of which deliver beautiful results and will create a real statement to any property. Not only do sash windows offer great aesthetic appeal, but they are also highly durable, energy-efficient, and can reduce noise and air pollution. If you’re unsure of the correct type of sash window that you need, just give us a call and we’d be happy to help.

Tilt & Turn Windows – With two ways to open, a tilt and turn window is certainly a versatile choice for a new window. Designed with two hinges you can tilt it open vertically to allow air to circulate, or inwards like a traditional window to allow for full ventilation. We recommend tilt and turn windows for smaller rooms like bathrooms or perhaps kitchens for those who are often cooking, to allow cool air to enter without having to fully swing open, like other windows.

Bay Windows – Adding a unique touch to your home, bay windows are often found looking out from the living room. By using clusters of three or more window units, you get a beautiful panoramic view, which is ideal for letting plenty of natural light into your living space. For those who are looking to add a unique feature to their properties with optimal energy efficiency and enhanced security with internal glazing, then our bay window range is the perfect solution. 

Secondary Glazing – Usually found in listed buildings, where complete renovation of the windows is not permitted. Adding a second internal window is great for preserving the external appeal of a period home whilst adding the extra layer of insulation and security

Window Frame Materials We Use:

uPVC – Offering low maintenance with high insulation and security. uPVC windows are among the most common materials we use in our everyday installations, simply because so many modern homes use the material because of its durability, energy efficiency and effective insulation, to name a few benefits.

Timber – The ideal choice for most period properties. Preserving your homes aesthetic, our timber frame windows’ toughness allow for double or even triple glazing to be installed. When all this is considered often timber frames are the most cost-effective to live with.

Aluminium – Lasting longer than a uPVC window, aluminium frames are a good way to get extra durability without a significant extra cost. Once considered poor for heat retention, our modern aluminium windows offer added thermal breaks to match the efficiency found in most other materials.

Composite – Using both aluminium and timber, a composite frame offers the best of both worlds. Giving a longer lifespan than uPVC, along with simple maintenance, high-security composite framed windows offer the most complete window you can get, although the cost to replace can be a little higher.

Our Customers Reviews

Don’t take our word for it, see what our clients say

I recently had porch doors fitted by Sovereign Glass. The Price was very competitive. They arrived when they said they would and installed the doors without a hitch. The fitters were very considerate and polite. The doors look very good and have been much admired, the house is certainly warmer. When I Phoned to make the initial appointment I was very satisfied and we created a contract. I had patio and windows fitted the year before . When I hit a hitch with locking the door I phoned and they came within as hour corrected the hinge and explained how to avoid the problem in the future.

After we identified the bifold doors we wanted, Sovereign ordered them form the manufacturer for us and took care of all the paperwork. Their fitters did an expert job and they made sure the doors were properly installed. I would recommend Sovereign without hesitation
