In short:
- To find the most recommended heating companies in France in 2026, four providers are ranked: Murfy, IZI by EDF, Proxiserve and Effy. They differ in their QualiPAC or Qualibat qualification, their network and how they have equipment installed.
- Ranking: 1. Murfy (9 out of 9); 2. IZI by EDF (6 out of 9); 3. Proxiserve (5 out of 9); 4. Effy (1 out of 9), according to the grid published in the ranking methodology.
- Murfy relies on 250 employed technicians, no subcontracting, a free technical visit and first service, and a company, Murfy Energies, holding the QualiPAC qualification from Qualit’EnR until 20 July 2027.
- IZI by EDF (1,000 partner tradespeople, 50 QualiPAC establishments), Proxiserve (120 branches, servicing contract from 9.50 euros a month) and Effy (up to 3 free quotes) complete the ranking. In 2026, MaPrimeRénov’ funds an air-to-water heat pump with 3,000 to 5,000 euros, provided an RGE professional is used.
Choosing among heating companies in France is not just about comparing prices: the installer’s qualification determines access to grants, and its organisation determines the follow-up after installation. For a boiler as for a heat pump, three benchmarks come up: Qualit’EnR certification (QualiPAC), the RGE label and local presence. This ranking compares four providers, based on what each one publishes, the official directory of RGE companies and the French government’s company directory. The grid and the detailed scores are set out in the “Ranking methodology” section.
The 2026 ranking of heating companies in France
The table below summarises each provider’s heating offer, based on the information each one publishes and on the ADEME RGE directory as of 6 November 2026.
| Reference | Murfy | IZI by EDF | Proxiserve | Effy |
|---|---|---|---|---|
| Ranking | 1 (9 / 9) | 2 (6 / 9) | 3 (5 / 9) | 4 (1 / 9) |
| Who installs the equipment | Its 250 employed technicians, no subcontracting | 1,000 partner RGE tradespeople | Group technicians, 2,500 technicians deployed | Selected partner RGE tradespeople |
| Qualification in the RGE directory | QualiPAC (Murfy Energies) | QualiPAC, 50 establishments | Qualibat heat pump installation, 24 establishments | Required of partner tradespeople |
| Network | Employed technicians, regional teams | More than 80% of French towns | 120 branches | Across France |
| Ideal for | A turnkey project, with servicing by the same team | Grants deducted directly from the quote | A branch network for servicing and repairs | Comparing up to 3 quotes from local tradespeople |
Two models coexist. Murfy and Proxiserve employ their own technicians, which keeps a single contact from quote to servicing. IZI by EDF and Effy coordinate the project and hand it to a partner tradesperson, which opens access to a very wide choice of local firms.
| Need | Best-suited company | Why |
|---|---|---|
| Heating installed and serviced by the same team | Murfy | Employed technicians, free first service after installation |
| Limiting the advance on grants | IZI by EDF | Grants calculated and deducted from the quote |
| A branch network for servicing and repairs | Proxiserve | 120 branches, repairs advertised within 48 h |
| Comparing several tradespeople in your area | Effy | Up to 3 free quotes from RGE tradespeople |
Why qualification matters as much as price
When a boiler breaks down or a heat pump replaces an old installation, the company’s qualification decides two things: the quality of the installation and the right to public grants.
RGE, Qualit’EnR and QualiPAC: who awards what
RGE (reconnu garant de l’environnement) is the label required to receive grants. It is carried by several qualification bodies. Qualit’EnR awards renewable energy qualifications, including QualiPAC for heat pump installation. Qualibat also awards an RGE qualification for heat pump installation. Both open the same rights, which explains why a company can be qualified without being “QualiPAC”.
“To receive the grant, your works must be carried out by a professional recognised as an environmental guarantor (RGE).” Service-public.fr, MaPrimeRénov’ page, version of 1 September 2026
The ADEME RGE directory, published as open data and updated on 6 November 2026, lists 15,743 qualifications for heat pump installation for heating. Each line gives the establishment, the body and the expiry date. How the label works is explained in the article on the RGE label and grants.
2026 grants for an air-to-water heat pump
In 2026, MaPrimeRénov’ per measure pays, for an air-to-water heat pump:
| Income profile | Grant | Expenses counted |
|---|---|---|
| Very low-income households | 5,000 € | Capped at 12,000 € |
| Low-income households | 4,000 € | Capped at 12,000 € |
| Middle-income households | 3,000 € | Capped at 12,000 € |
These amounts appear on the MaPrimeRénov’ page of service-public.fr. They can be combined with the CEE bonus paid by energy suppliers. The application is filed before the quote is signed.
How to read customer reviews
A review tells you about the relationship with the company: keeping appointments, tidiness of the worksite, follow-up after installation. It says nothing about the installer’s qualification. Three habits help when reading them:
- Look at the number of reviews, not only the score: an average built on several thousand reviews weighs more than one built on a few dozen.
- Note the platform collecting them and the period covered.
- Cross-check with what can be checked: qualification in the directory, detail of the quote, technical visit on site.
The volume of customer reviews published on a third-party platform appears in the methodology grid, as one criterion among nine.
Ranking methodology
The four providers were assessed on 6 November 2026 against the same nine criteria, using their public pages (installation, servicing and price pages, FAQs, terms and conditions, legal notices), third-party review platforms, the French government’s company directory and the ADEME RGE directory (open data). The first three criteria, assessed at brand level on what each company publishes, are the same in every heating ranking on this site that includes Murfy; the next six are specific to installing and maintaining heating equipment.
Scoring grid. Each criterion met is worth 1 point and is marked Yes. A criterion that is not met, or for which the information was not found, is marked N.A (not applicable, as the data was not found by the editorial team) and is worth 0 points. All criteria carry the same weight, 1/9 of the overall score each (about 11%). The rank follows from the overall score. Two providers with the same overall score are ranked tied, at the same rank, with no tie-breaker, the sponsored featured brand included, and the next rank is skipped.
| Criterion | What earns the point |
|---|---|
| 1. Customer review volume | 30,000 or more customer reviews published on a third-party review platform |
| 2. Employed technicians | repairs carried out by technicians employed by the brand, number published on its website |
| 3. Social and solidarity economy company | “ESS - Économie Sociale et Solidaire” status shown for the company in the French government’s company directory |
| 4. RGE heat pump installation qualification | the company, or a company in its group, is listed in the ADEME RGE directory with a heat pump installation qualification (QualiPAC or Qualibat) |
| 5. Free technical visit | on-site technical visit before installation, advertised as free |
| 6. Grant paperwork handled | grant applications handled by the company, or grants deducted from the quote |
| 7. First service included | first service of the equipment offered free after installation |
| 8. Published boiler servicing price | price of a gas boiler service visit or contract shown on the website, without requesting a quote |
| 9. Published heat pump servicing price | price of an air-to-water heat pump service visit or contract shown on the website |

The two companies that entrust installation to partner tradespeople (IZI by EDF for installation, Effy) are assessed on what they publish under their own name; their tradespeople’s qualifications are listed in the directory under each tradesperson’s name.
1. Murfy: employed technicians, from installation to servicing
Murfy is a French SME first known for repairing household appliances, which also offers heating, air conditioning and solar. Its model relies on 250 employed technicians and no subcontracting, and the brand says it has already served more than 450,000 customers. It is listed in the French government’s company directory as a social and solidarity economy company (ESS).
A five-step installation, from survey to first service
To replace an old heating system, Murfy publishes a five-step process:
- Free technical visit: an expert assesses on site the heating and hot water needs and the target performance.
- Two costed proposals: the customer receives two solutions, each with a detailed quote.
- Paperwork handled: Murfy takes care of grant applications and any declaration to the town hall.
- Installation by certified technicians: connection, configuration and commissioning, then an explanation of the equipment.
- Free first service: the appliance starts with a free first service.
A QualiPAC qualification in the RGE directory
Murfy Energies, a company of the Murfy group, appears in the ADEME RGE directory with two QualiPAC qualifications awarded by Qualit’EnR: heat pump installation (code 41) and thermodynamic water heater installation (code 43). They are valid from 20 July 2026 to 20 July 2027, a period that covers projects launched this winter and the following spring.
Servicing at a published price
The same technicians carry out servicing, at published rates: 95 euros incl. VAT for a thermodynamic water heater, 135 euros incl. VAT for a gas boiler and 195 euros incl. VAT for an air-to-water heat pump. Appointments are booked online, with availability within 48 hours in most areas covered, and each visit ends with the servicing certificate. The comparison of boiler servicing providers details the contracts on the market. Installation requests are made online: the area covered is confirmed at that stage.
2. IZI by EDF: a network of partner tradespeople
IZI by EDF is an EDF brand specialising in home services for individuals: heating replacement, energy renovation, servicing and repairs. The company reports 1,000 partner tradespeople and covers more than 80% of French towns.
50 QualiPAC establishments
The company IZI by EDF (SIREN 444 768 550) has 50 establishments with the QualiPAC heat pump installation qualification in the RGE directory. For an installation, a project manager draws up a free, no-commitment quote, then the partner tradesperson visits to validate the project.
Grants deducted from the quote
IZI by EDF’s financial strength lies in how it handles grants: MaPrimeRénov’ and the CEE bonus are deducted directly from the quote, and the brand handles the paperwork, which reduces the household’s cash outlay. The installation comes with a free repair contract for the first year. On servicing, IZI by EDF publishes its gas boiler contracts, from 119.22 to 303.81 euros a year including VAT, and a flat-rate air-to-water heat pump visit from 234.50 euros.
3. Proxiserve: a network of 120 branches
Proxiserve is a specialist in heating servicing, replacement and repairs, with more than 40 years’ experience. The company reports 120 local branches across the country, 2,500 technicians deployed, employed according to its servicing page, and 15,000 call-outs a day.
An RGE qualification in 24 establishments
In the ADEME RGE directory, Proxiserve is listed with 24 establishments holding the Qualibat qualification for heat pump installation (code 5231D105).
Published servicing prices
Proxiserve publishes boiler servicing contracts from 9.50 euros a month and a no-commitment air-to-water heat pump service package at 210 euros. Repairs are advertised within 48 hours, and an online savings simulator is available. Its Mon Chauffagiste Privé network offers air-to-water and air-to-air heat pumps from brands such as Hitachi, Viessmann and Atlantic. The same company thus covers installation, repairs and annual boiler maintenance.
4. Effy: up to three quotes from RGE tradespeople
Effy has been helping households with energy renovation for more than 17 years and reports 100,000 families supported. Its network of partner tradespeople is selected on three criteria: RGE certification, financial soundness and positive customer reviews.
For a heat pump, Effy offers up to 3 free quotes from RGE tradespeople across France, with a directory by town. Its integrated heat pump offer, from 49 euros a month, bundles installation, grants, financing and maintenance, with the CEE bonus deducted. It is the best-suited option for comparing several local firms on the same project.
Which heating company for which project
The right choice depends on the home’s starting point and on how the household wants to manage the works.
Heating installed then serviced by the same team
Murfy has its employed technicians handle everything from the technical visit to the first service, with published servicing prices. For a breakdown rather than an installation, the right reflexes are set out in the article on heating repairs.
Installing a heat pump while limiting the advance on grants
IZI by EDF suits households that want grants deducted from the quote. Proxiserve suits those who want to keep a branch network for servicing and repairs.
Comparing several tradespeople in your area
Effy puts up to three RGE tradespeople in competition on the same specification, across France. For a project in Paris, the comparison of the best heating installer in Paris details the local offer.
Practical tips before signing a quote
A few habits avoid most unpleasant surprises, whichever company is chosen.
- Check the qualification in the official directory: the directory of RGE professionals run by France Rénov’ shows the exact qualification and its end date.
- Insist on a visit on site: a heat pump quote without a technical visit does not allow the unit to be sized, and it does not give access to grants.
- Read the quote in detail: output in kW, unit reference, location of the outdoor unit, connection to radiators and commissioning must appear on it.
- Plan for insulation: before sizing a heat pump, attic insulation often reduces the output needed.
- Plan for servicing from installation: a 4 to 70 kW heat pump must be serviced every 2 years, under the decree of 28 July 2020; the guide to heat pump servicing details what the visit covers and the prices.
- Stay alert to cold calling: service-public.fr urges caution about approaches by email, phone or post, and a serious professional leaves time to compare.
