Grants for engineering and consulting firms (bureaux d'études)
In brief
An engineering consulting firm never receives any of these grants directly: they fund the client who commissions a feasibility or opportunity study — geothermal energy, solar thermal, industrial decarbonization, multi-renewable-energy approaches. Very largely run by ADEME. This page lists the schemes currently validated, with their funder and maximum amount where available.
None of the grants listed here are paid to the engineering consulting firm itself: they all fund the client who commissions the study.
Most are run by ADEME and fund feasibility or opportunity studies very early in a project — deep or shallow geothermal energy, solar thermal, industrial decarbonization, a multi-renewable-energy approach.
This is exactly the type of service an engineering consulting firm bills to its client: knowing about these schemes means you can mention them at the very first meeting, making it easier for the client to decide to commission the study.
For studies and work specifically concerning a building listed or registered as a historic monument (heritage architect, DRAC), see the "building trades and construction" page, which lists those grants separately.
Run a personalised scan to identify the public grants and funding your company may be able to access.
Who actually receives these grants?
The client who commissions the study, never the engineering consulting firm that carries it out.
The funding covers the cost of the study itself (feasibility, opportunity, diagnostic), not any resulting works.
How much can be obtained?
The maximum amount is currently not specified for any of the schemes listed for this trade.
The amount actually paid depends on the type of study, its nature (feasibility, opportunity, diagnostic) and the size of the project.
How to use this information with your clients?
Presenting these schemes as early as the first contact can make it easier for your client to decide to commission a feasibility or opportunity study.
The exact nature of the study (geothermal energy, solar thermal, decarbonization, multi-renewables) determines which scheme applies.

Frequently asked questions about grants for engineering consulting firms
Are these grants paid to the engineering consulting firm or to its client?
None of these 9 grants are paid to the engineering consulting firm: they all fund the client who commissions the study.
The full list is shown further up this page, with the funder for each grant.
Do these grants fund the study or the works that result from it?
Only the study itself — feasibility, opportunity or diagnostic — not any works that might result from it.
Funding for the works, if any, falls under other schemes specific to the nature of the final project.
How can these grants help me sell my services?
By mentioning this funding as early as the first meeting, you make it easier for your client to decide to commission the study rather than abandon it for lack of budget.
This page does not assume the eligibility of any specific project; a personalized diagnostic checks it against the real criteria.
How does my client apply for this type of grant?
The application is most often made directly with ADEME or the relevant Region, before the study begins.
A personalized diagnostic identifies the schemes that are genuinely relevant to your client's project, before starting the process.
