Safety and quality always come first

When making your home more sustainable, you want to make sure everything is done properly and safely. That is why DuurzaamXL is a member of InstallQ and recognised as both an installation and inspection company. This independent quality register verifies whether companies really meet the competence and quality requirements that apply in the Netherlands.

What does this mean for you?
- Safe installation - You can be sure that, for example, your solar panels,
home battery or charging station is installed by a professional who has the right knowledge and experience.
- Recognised quality - InstallQ installers meet national standards and
regulations. This gives you security on delivery and in the long term.
- Extra guarantee - Many insurers and municipalities today require a
InstallQ-certified company in grant or insurance applications. With
SustainableXL is therefore always right for you.

When you have solar panels installed, you want them to be safe in addition to yielding returns. That is why SustainableXL SCOPE employs 12 certified employees. So you, the client, know that your installation will be installed safely.

Why is that important?
- Safety first - Scope 12 is designed to minimise fire risks in solar panels.
- Reliable operation - You know your installation is connected optimally and without defects.
- Independent monitoring - Inspections are carried out according to nationally established rules.

Specifically for you
As a client of SustainableXL, you will receive an installation that meets all the
safety regulations. Moreover, a SCIOS SCOPE 12 inspection often helps claim insurance or subsidies.

Many sustainable solutions - such as heat pumps and air conditioners - use refrigerants, also known as F-gases. These substances are essential for operation, but can be harmful to the environment if used incorrectly. It is therefore a legal requirement that only certified companies are allowed to work with F-gases.

SustainableXL is Kiwa F-Gases certified. This means that:
- Safe handling of refrigerants - Our technicians are specially trained and
Competent to work with F-gases.
- Environmentally conscious - We ensure proper installation and maintenance, so no harmful substances are released.
- Legal obligation - By working with SustainableXL, you can be sure that your installation complies with all regulations.

This gives you the assurance that your heat pump or air conditioner is not only working properly, but also managed in an environmentally friendly and safe way.
