Certified heating engineer: RGE, Qualibat and key labels

Choosing a certified heating engineer is an essential step in ensuring the safety, quality and sustainability of your heating installations.
Faced with the multiplication of artisans and online offers, it is often difficult to distinguish a qualified professional from a simple handyman.
This is where official certifications such as RGE, Qualibat, QualiBat, QualiGaz, or QualiPAC come in, real guarantees of trust and competence.
In this article, we explain why these labels are important, how to check them, and how to choose a certified heating engineer in Paris with complete peace of mind.
Why use a certified heating engineer?
Entrusting the installation or maintenance of your heating system to a certified professional is above all a question of safety and reliability.
These certifications guarantee that the craftsman respects the technical and environmental standards in force.
A certified heating engineer assures you:
- An installation that complies with French regulations.
- Safe interventions, especially for gas or oil systems.
- Access to public financial aid (MaPrimeRénov', CEE, eco-loan).
- A ten-year guarantee covering the work over the long term.
Using a certified craftsman therefore means investing in quality, avoiding unpleasant surprises and benefiting from professional support.
Understand the main certifications of the heating engineer
Certifications make it possible to recognize qualified companies in their field.
They are issued by independent organizations that verify the skills, rigor and compliance of the professional.
RGE certification (Recognized Environmental Guarantor)
The RGE label is now the reference in the energy renovation sector.
Awarded by the State, it distinguishes artisans engaged in work that respects the environment and complies with current energy standards.
An RGE heating engineer is trained to:
- Install energy-efficient equipment (condensing boiler, heat pump, etc.).
- Carry out thermal insulation or global renovation work.
- To provide benefits that qualify for State aid.
This label is mandatory to benefit from devices such as MaPrimeRénov', Energy Saving Certificates (CEE) or tax credits.
In practice, an RGE professional is committed to continuous training, to undergo regular audits, and to maintain a high level of quality.
The Qualibat qualification
Qualibat certification attests to the technical and administrative skills of a building company.
It assesses the quality of the work, financial stability, insurance, and the seriousness of the company.
Qualibat heating engineers may hold various mentions:
- Qualibat Plumbing-Heating: installation and maintenance of thermal networks.
- Qualibat Renewable energies: for hybrid or ecological systems.
- Qualibat Maintenance: for monitoring and maintaining existing installations.
This certification is a guarantee of trust for individuals and trustees looking for a reliable and well-insured company.
The QualiGaz, QualiPAC and QualiBois labels
QualiGaz
Specifically dedicated to natural gas installations, the QualiGaz label guarantees the safety and compliance of your system.
It is essential for any commissioning of a gas boiler, water heater or gas stove.
The heating engineer must comply with the NF DTU 61.1 standard and provide a certificate of compliance after intervention.
QualiPAC
The QualiPAC label is aimed at artisans specialized in air/air and air/water heat pumps.
It attests to a complete mastery of reversible heating and air conditioning technologies, including sizing, installation and commissioning.
QualiBois
This label concerns wood or pellet boilers and stoves.
A QualiBois professional is committed to creating installations that comply with thermal regulations, while guaranteeing the optimal performance of the devices.

How do I check the certification of a heating engineer?
Before signing a quote, it is essential to verify the authenticity of the professional's certifications.
Unfortunately, some artisans display expired or unrecognized labels.
Here's how to do it:
- Ask for the qualification number or a copy of the official certificate.
- Consult the official directories:
- Verify that the label is valid on the date of the quotation.
- Read customer reviews and ask for references to recent projects.
Finally, make sure that the heating engineer has up-to-date ten-year insurance and professional liability.
What are the advantages of an RGE certified heating engineer?
Using an RGE heating engineer has many advantages, both financial, technical and ecological.
- Energy savings: efficient installations permanently reduce your bills.
- Financial aid: only work carried out by an RGE professional is eligible for public aid.
- Quality guarantee: each RGE site is subject to regular checks and audits.
- Ecological contribution: a concrete commitment to the energy transition.
Beyond the label, an RGE heating engineer is above all a trusted partner, who advises you on the equipment best suited to your home.
Mistakes to avoid when choosing a heating engineer
Even with the best of intentions, mistakes can be costly.
Here are the most common ones:
- Choose a professional only for its attractive price.
- Do not check the validity of certifications.
- Forget to ask for a clear and detailed quote.
- Entrust the work to an undeclared or uninsured craftsman.
A quotation that is too vague or does not mention the RGE label should immediately arouse distrust.
A certified heating engineer always provides comprehensive documentation, including warranties and respected standards.
