Double Glazing Companies, Schemes, and Accreditations

We know that looking through double glazing companies can sometimes be a daunting process, especially if you’re not sure what you’re looking for when it comes to reliability and certified standards of service and competency. Fortunately, there are a few things you can look out for to ensure you make a confident and informed decision when it comes to traversing double glazing companies across the country.

One of the most important things you should consider when it comes to double glazing is whether the company is involved in any schemes or is certified by any governing bodies. This way, you can rest assured that you’ll be investing in a standard of quality that has been certified by a professional organisation. Two of the stand out companies you should be looking for are the Double Glazing and Conservatory Ombudsman Scheme (DGCOS) and the Fenestration Self-Assement Scheme (FENSA).

The Double Glazing and Conservatory Ombudsman Scheme (DGCOS)

As mentioned, you can check up on the standard of double glazing companies by seeing what schemes they are involved in: which includes The Double Glazing and Conservatory Ombudsman Scheme (DGCOS). This scheme has been initiated as a consumer protection organisation, which has been put in place to mediate in the event that you have a dispute with one of their accredited members. As it stands, this is the only organisation of its type operating within the double glazing industry. This is an important scheme to look out for because all double glazing companies have to undertake a stringent assessment process to get their membership!

In the case that you pay a deposit to a double glazing company that is part of the DGCOS, you can rest assured that your money is protected under the scheme. This means that in the unlikely event that the double glazing company goes out of business, you won’t have to worry about losing your money as a result. All in all, the DGCOS is an important scheme to be looking for when you’re browsing double glazing companies.

The DGCOS does not charge homeowners in the event that mediation is necessary. It promises to:

Help fully resolve any issues free of charge;

Provide inspections (also at no cost) to help with product or installation issues (although this is not guaranteed and is at their discretion);

Help homeowners to resolve any disputes without any need for them to incur legal costs;
Provide access to a fund that can be used for compensation, thereby ensuring homeowners aren’t left worse off.

Double glazing companies also prove their competence over time. That is to say, they are rigorously re-assessed to prove they are just as competent and reliable as when they first joined the DGCOS.

Fenestration Self-Assessment Scheme

The Fenestration Self-Assessment Scheme (FENSA) was established as a Competent Person Scheme (CPS), currently operating as a governing body that is responsible for regulating double glazing companies for their standards of service. In a similar process to DGCOS, double glazing companies are required to apply to FENSA to ensure they are working in full compliance with all current building regulation. When you’re looking through double glazing companies in your area, it’s always a bonus if they are FENSA registered.

If you find yourself unsure as to whether the double glazing companies you are looking at are FENSA registered, you can find yours by browsing the FENSA directory. Simply visit the FENSA website and look for them through the easy to use search tool, inputting either their name, location or their FENSA company number. Through this method, you can gain the peace of mind that comes with knowing you’re dealing with a professional.

What Can Double Glazing Companies Offer?

A Wide Product Range

Double glazing companies should be able to offer you a wide product range, offering you the freedom to find the right product to suit you, your tastes, and your budgets.

Not only is it important to be able to choose from a wide range of products, it’s also important for you to be able to enhance your home with the best designs. To do this, make sure any double glazing companies you are looking at are offering you the latest designs.

In terms of double glazing companies, there are advantages to both the local and national variants.

Potentially, but not always. As mentioned, a bigger company may have more freedom when it comes to lowering prices due to less financial restraints. However, a local installer may be willing to offer you a better deal with a more personal approach. We recommend putting your feelers out and seeing what you can get in your area before rushing ahead.
