Top 10 Double Glazing Companies

The best double glazing companies are determined by a number of factors, and despite a company being one of the best double glazing suppliers, there can still be problems from time to time. When looking for double glazing prices and the best deals, bear in mind that the cheapest may not always be the best. It is always best to research double glazing companies reviews, and see what their reputation as a whole is like.

Rather than the windows themselves, most complaints tend to be surrounding the clarity of information provided when it comes to contracts, and it taking longer to install than expected. It is therefore often a good idea to factor in extra time for the installation. Other things that may go wrong include scratches to the frames or difficulty locking for example, but these types of problems are minimal, especially from a reputable supplier.

We want to make it easy for you searching for double glazing companies reviews. The best double glazing companies have their windows energy efficiency rated by The Energy Saving Trust, and security validated by Secured By Design (SBD), the official police security initiative. Websites which provide customer feedback ratings, such as TrustPilot, and that carry out independent research, such as Which?, have helped us compile our researched list of the best double glazing companies. These are in no particular order, and give an overview of the best UK double glazing companies.
