Which are the Best uPVC Windows in the UK?

To find the best uPVC windows in the UK, you’ll need to consider what it is you want for your home and what your budget is.

At first glance, windows may seem to be much the same. However, when you start to shop around, you’ll soon realise just how much variety there is on the UK market. Having a wide range of options for windows is ideal for finding the perfect fit for your home, but it can also be overwhelming to navigate through all the choices.

Factors to consider when choosing your ideal windows

choosing upvc windows

Some of the main things to consider are the type of glazing (i.e. single, double, triple, or secondary glazing) you want, the window cost and the brand. It is possible to find relatively cheap uPVC windows for good quality. Below we’ve broken down some other factors that may help you when it comes to choosing your ideal windows:

  1. Window type: Whether you’re looking for standard window designs or something more specific such as top hung uPVC windows or modern tilt-and-turn windows, there will be a window that suits your style and functional needs.
  2. Frame material: You may have already decided that you want a uPVC window, but did you know it’s possible to buy a uPVC window with a wood grain effect? This can boost the style of your home, but keep in mind that wood effect uPVC windows can cost more.
  3. Energy rating: A window with a high energy rating will help reduce your energy bills.
  4. Security: Consider the type of lock and security accreditations for each window. This way, you can ensure that your home is well-protected against break-ins.
  5. Sustainability: If you’re a conscious consumer, you’ll want to consider the ethos of each window brand. In addition, looking at the warranty for each type of window will give you a better idea of its longevity.

Everyone’s needs and preferences are different, so what one person considers “the best” might not be the same for someone else. Nevertheless, there are still some factors you can be mindful of when assessing quality.

What makes a good quality uPVC window?

A good quality uPVC window should have efficient glazing and a durable frame. As well as having superior materials, you need to ensure that you hire an installer who is meticulous in their work. We’ll discuss each of these factors in more detail below.


When evaluating frames, you need to check that the frame is sturdy and well-constructed. It should have reinforced corners, weather-stripping, and a good sealant to prevent drafts and leaks.

A good sealant and weather-stripping will help reduce your window warping over time as well as lower your heating bills. Reinforcing your window frames will help make your home more resistant to forced entry and breakage.


In terms of glazing, there are several options available, each with its own benefits. Double glazed uPVC windows are considered to be one of the most energy-efficient options as it has two layers of glass with a sealed air space in between, which improves insulation. Around 90% of homes in the UK have double glazed windows, making it the most sought-after option.

Other glazing options include single, triple, and secondary glazing. Single glazed windows generally aren’t recommended, as they do not provide much security or insulation. However, you may still find them in historic buildings.

Triple glazing is becoming more popular due to its advances in insulation, security, and noise reduction compared to double glazing. However, it is typically more expensive, so you’ll need to assess whether the benefits justify the cost.

Lastly, there is secondary glazing. This is when a slimline window is added to the existing window units. This helps insulate the home and significantly reduce noise pollution in comparison to single glazing. However, it is not as effective as double glazed windows. Secondary glazing is commonly installed in Grade I or Grade II listed buildings as an alternative to double glazing.

Alongside the glazing type, you should consider the type of glass used for the panes. For example, tempered glass with a Low-E (Low-Emissivity) coating is a good choice. Tempered glass is four times stronger than regular glass, making breakage less likely. While Low-E reflects heat back inside the room, making your window more energy-efficient.


As previously mentioned, hiring an experienced and qualified installer is critical. Otherwise, your window won’t reach its full potential, no matter how good the materials are.

If you’re based in Great Britain, then it is a good idea to look out for installers who are FENSA accredited. FENSA is a government-authorised scheme that ensures your window installation complies with building regulations, is energy efficient, and registered with your local council.

Another accreditation to look for is from DGCOS (Double Glazing & Conservatory Ombudsman Scheme). DGCOS is a consumer protection organisation which provides independent dispute resolution for customers who have issues with their windows. Window companies with this accreditation must adhere to the code of conduct and provide all of their customers with a guarantee of at least 10 years.
