Why uPVC windows?

uPVC (Unplasticised Polyvinyl Chloride) is a common material used for windows as it’s durable, energy efficient and easy to maintain. They are safe thanks to their multipoint locking systems and its characteristics make it a popular choice for homeowners. Some of the other benefits are:

  • They are easy to clean.
  • uPVC stops heat escaping easily.
  • There are lots of colours and finishes available.
  • They are good for soundproofing.
  • New windows will save you money on your household bills.
  • They are cost effective as they will last many years.

Finding and comparing uPVC installers

In most cases, the manufacturer is simply the supplier of the windows and will not install them for you.

However, they may be able to give you a list of installers in your area that they recommend. As the purchaser and homeowner, it is up to you to decide which installer you would like to use to fit your windows.

There are local, regional and national installers available, so be sure to do your research online to find one you’re happy with.

Manufacturers and installers

Some installers will work with specific manufacturers only, so ensure you’re happy with the company they are sourcing your windows from.

Similarly, manufacturers may take care of the whole process, and use an installer that they have a contract or agreement with.

Look at examples

A picture speaks a thousand words, so make sure to ask to look at examples of the windows the company have installed previously.

It’s a good way to check they are reputable, and have had experience in the type of work you would like completed. If they cannot provide any photos, it’s best to steer clear.

Choosing a local or national installer

There are lots of options when it comes to installing your windows and whether you decide to go with a local or national business, be sure to check the following:

  • How many years have they been in business?
  • Do you want to support a smaller business?
  • If they are local, check their recent work in your area.
  • Do they have a reputable website and contact information?
  • What are the price differences?
  • How quickly can they attend to a problem?
  • Will the service be personal?


To make sure your installer has a high level of experience and competence, it’s important to check their certification. Check they have the right qualifications and are registered with the appropriate trade bodies.

Also ensure you will receive a FENSA certificate when the work is complete. You should also check that they have good reviews and ratings – you can do this on their social media, website, or review pages such as Trust Pilot.

Ask about the guarantee

Before you choose an installer, check that they offer at least a 10-year guarantee on their work. This should include the installation and the uPVC frames.

Different fixtures may carry different warranty terms, so be clear on this before you commit.

Get quotes from window installers

Once you’ve found the perfect manufacturer, it’s important to find an installer that you trust.

By following the steps in this guide, you should be confident that your manufacturer and installer will provide you with a great product and excellent service.
