Plumber Certifications in France: What to Check in Paris
No particular label is expected to fix a leak or unblock a sink in France. Labels matter for specific jobs: RGE for state-funded energy renovation, the PG designation for gas, Qualibat and Qualit'EnR as proof of competence. Whatever the job, check the company's registration, its insurance and get a written quote.
Need a plumber in Paris or the inner suburbs? Call +33 1 89 70 15 36 (01 89 70 15 36 from a French phone), 7 days a week, 24 hours a day, or write to us through the contact page or WhatsApp. Many of our plumbers speak English. For an emergency, see our 7-day emergency plumbing service; for small jobs, our everyday plumbing page.
This guide works for checking any plumber, including us: what each French label covers, where to verify it in two minutes, and the other criteria that matter as much as a logo on a quote (a devis).
Do you need a certified plumber for every job?
No. There are three different situations.
- Routine repairs (a leaking flexible hose, a dripping tap, a blocked toilet, a worn seal): no particular label is expected. What matters is an identifiable, insured company that gives you a price before it starts.
- Gas work (boiler, gas water heater, connected cooker): choose a professional trained for gas and ask to see their designation (see below). The safety of the whole building is at stake.
- Energy renovation work for which you are claiming state aid (heat pump, heat pump water heater, high-efficiency boiler): the company must be RGE for that type of work, otherwise aid such as MaPrimeRénov' or energy savings certificates (CEE) is not granted.
In other words, a plumber without RGE can be an excellent repair plumber. And an RGE logo on a van says nothing about their skill with a leak under a sink.
The main French labels and qualifications
RGE (Reconnu Garant de l'Environnement)
RGE, roughly "recognised environmental guarantor", is not a separate state label: it is a mention attached to a qualification issued by a body such as Qualibat, Qualit'EnR or Qualifelec. Three things to know:
- it is granted to a company, not to a person;
- it applies to a specific type of work: a company that is RGE for insulation is not necessarily RGE for heat pumps;
- it has an expiry date and involves site inspections.
It is the condition for your energy renovation work to qualify for MaPrimeRénov', CEE or the zero-interest eco-loan (éco-prêt à taux zéro).
Qualibat
Qualibat is the main qualification body for the French building trades. It assesses a company's technical skills, administrative and financial standing, and insurance. Its qualifications are granted per activity (plumbing and sanitation, heating, renewable energy, maintenance), so check that the qualified activity matches your work. A Qualibat qualification can carry the RGE mention.
Qualit'EnR: QualiPAC, QualiSol, QualiBois
Qualit'EnR qualifies installers of renewable energy equipment:
- QualiPAC: heat pumps and heat pump water heaters;
- QualiSol: solar water heaters;
- QualiBois: wood and pellet boilers and stoves.
These qualifications usually carry the RGE mention. They do not cover everyday sanitary plumbing.
Gas: the PG designation and the certificate of conformity
For gas, look for the PG designation (Professionnel du Gaz), also written PGN for natural gas and PGP for propane. It shows an installer trained for gas installations and monitored over time. You can check it with Qualigaz, the body that manages it. After a new installation or a significant modification, ask for the certificate of conformity (certificat de conformité) of the gas installation: it is the document the supplier will ask for before turning the gas on.
In a Paris building, where a wall-hung boiler or gas water heater often shares an old flue, this is not a detail.
What about products?
Searches for "plumbing certification" sometimes concern products rather than tradespeople. For pipes, taps and fittings in contact with drinking water, ask for products carrying the NF mark or a sanitary conformity certificate (ACS). A serious professional can tell you what they are fitting.
What "approved plumber" means
"Agréé" (approved) is not a certification. It usually means a tradesperson listed by an insurer, a landlord or a platform. It is not a quality guarantee in itself: simply ask "approved by whom, and for what".
Insurance: decennial and liability cover
Insurance protects you better than a logo. Ask for two certificates:
- Professional liability insurance (responsabilité civile professionnelle) covers damage caused during the job, for example water damage to the flat below while a water heater is being replaced.
- Decennial insurance (assurance décennale) covers certain serious defects for ten years after construction or renovation work (a new bathroom, rerouted pipes inside walls). For a simple repair, it is mainly the liability cover that applies.
On the certificate, check three things: the company name (the same as on the quote), the activities covered (plumbing, heating, gas depending on your job) and the validity period.
How to check a plumber online in a few minutes
- Ask for the SIRET number (the French company registration number) and check it on the official company directory (annuaire-entreprises.data.gouv.fr) or on infogreffe.fr. The name, address and activity must match what you were told. A closed company, or an activity unrelated to plumbing, is a warning sign.
- Ask for the qualification number (Qualibat, Qualit'EnR, RGE) shown on the quote, then check it:
- on qualibat.com for Qualibat qualifications;
- on qualit-enr.org for QualiPAC, QualiSol, QualiBois;
- on the RGE directory of the public France Rénov' service (france-renov.gouv.fr).
- Check the expiry date: expired labels still appear on websites and business cards.
- Ask for the insurance certificate before signing a quote for works.
- Read recent, detailed reviews, especially the negative ones and how the company answers them. A handful of perfect reviews posted on the same day is less convincing than regular, detailed ones.
A transparent professional will send you this information without hesitation.
Beyond labels: what makes a plumber reliable
A clear identity and address
A company name, an address and contact details you can check. Be wary of anyone reachable only on a mobile number, with no trace online.
A price before travelling, a quote before the work
A serious plumber gives you a price range on the phone and a written quote before any significant work. The quote itemises labour, parts, call-out and VAT. To understand each line, read our article on the cost of a plumbing call-out in Paris, and see our prices.
A detailed invoice at the end
The invoice lists what was done. Keep it with the quote: you will need it for your insurer, in a dispute, or for the next tradesperson.
The right trade
A plumber deals with water: leaks, pipes, bathroom fittings, water heaters. A heating engineer (chauffagiste) deals with heating and boilers. Many companies do both. Our article on the difference between a plumber and a heating engineer helps you ask the right person.
Knowing Paris buildings
In Paris, a good plumber knows the building stock: Haussmann-era buildings, shared risers (colonnes montantes), old lead or cast iron pipes, sub-meters in landing ducts, access by the service staircase, work hours set by the building rules. They also know what belongs to your flat and what belongs to the co-ownership (copropriété), which is handled by the building manager (syndic). Finally, check they cover your area: see our service area (Paris, Hauts-de-Seine, Seine-Saint-Denis, Val-de-Marne).
Warning signs
- A very low price on the phone that becomes a large bill once the plumber is inside.
- A refusal to give a written quote before significant work.
- Pressure to replace equipment "urgently" with no explanation or photo of the fault.
- Cash only, no invoice.
- Labels shown with no checkable number, or an insurance certificate in another company's name.
These practices are covered in our article on plumbing scams in Paris.
Questions to ask on the first call
- What is your SIRET number and the exact name of the company that will do the job?
- Do you have professional liability insurance, and decennial insurance for this kind of work?
- For this job, do you hold a qualification (RGE, Qualibat, PG gas), and what is its number?
- Do you cover my arrondissement or town?
- Can you give me a price range, and a written quote before the work?
- Can you explain the job in English?
How they answer matters as much as the answers: a professional who explains and stays clear on prices is a good sign.
Choose before the emergency
The best time to choose a plumber is before you need one. When you move in, find a professional, save their number and, if possible, use them for a small job (a tap, a descaling) to judge how they work. Ask your concierge (gardien) or your building manager which tradespeople already know the building.
On the day of a leak, you will know who to call and will not have to choose in a hurry. While you wait: turn off the water, take photos, clear access and tell your landlord if you rent.
New arrivals and English-speaking residents
If you have just moved to Paris, the language and the way co-ownership buildings work make the search harder. Choose a professional who explains clearly what they are doing and what you are paying for. Many of our plumbers speak English and can handle the whole job in English. Our page for an English-speaking plumber in Paris explains how it works.
Frequently asked questions
What is a certified plumber in France?
A plumber whose company holds a qualification issued by an independent body (Qualibat, Qualit'EnR, Qualigaz for gas), sometimes with the RGE mention. There is no single label covering all plumbing: check which qualification matches your job.
How do I know if a plumber is Qualibat qualified?
Ask for the qualification number and search for the company on qualibat.com. Check the qualified activity and the expiry date.
Does a plumber need to be RGE?
Only if you want state aid for energy renovation work (heat pump, heat pump water heater, high-efficiency boiler). For a repair or a bathroom installation, it is not needed.
Which qualification is needed for gas work?
Ask for the PG designation (Professionnel du Gaz), which you can check with Qualigaz, and, after a new installation or modification, the certificate of conformity of the installation.
Is an "approved" plumber more reliable?
Not necessarily. "Approved" usually means listed by an insurer or a network, not certified. Make the same checks: SIRET, insurance, quote.
