Support for application for the Home Energy Conservation 2025 Campaign

The "Home Energy Conservation 2025 Campaign" is a general term for a subsidy system that strengthens support for energy-saving housing renovations, such as renovations that improve the insulation of homes and the introduction of high-efficiency water heaters, in order to promote energy conservation in the residential sector toward achieving carbon neutrality by 2050.

  • I want to apply, but I want to minimize the time and effort required for the process so I can focus on my main business.
  • There are so many documents to submit when applying (such as photos), I don't know if they are all correct.
  • There is no time to take additional measures such as dealing with incomplete application documents
  • Schedules such as application timing become complicated and difficult to manage
  • We handled the procedures for the Home Energy Conservation 2024 Campaign in-house, but are looking for an agent to continue the campaign.

We handle the application process for the Home Energy Saving 2025 Campaign on your behalf..

Subsidy application agency fees are included as miscellaneous expenses.

Would you like to proceed with the contract smoothly and increase your sales?

① Reduce the burden of in-house subsidy applications

We can outsource the in-house subsidy procedures and subsidy applications that were previously handled by sales personnel, reducing the burden.

Our specialist subsidy team handles subsidy applications. Up until now, we have applied for numerous equipment and housing subsidies.
After preparing the application form, we will submit it and also handle any corrections required after the application is submitted.
We have a wealth of experience in everything from preparing application documents to negotiating with the government.

②Thorough date management

We provide clear instructions on the necessary documents at each application stage, such as before and during construction, to prevent delays and omissions in applications.

In some cases, we will also handle documents from the applicant (orderer).

We can accommodate requests of 100 or more. We will guide you so that you can apply in plenty of time.

③ Providing services tailored to your business scale

In response to your company's consultations and requests, we provide services tailored to the size of your application.

We will listen to the issues that arise during the application process and guide you through the solution.
We have an in-house specialized team and can undertake large-scale subsidy work, even if the number of projects is 100 or more.
In addition, the management list is shared and the progress of all items is visualized, which prevents omissions.

④ It is also possible to apply for combined subsidies.

In addition to energy-saving residential projects, you can receive even more subsidies by combining various other subsidies, such as those from Cool Net Tokyo and Tokyo's municipalities (local governments).

⑤ Speedy response

Our motto is fast response.
We prepare all the necessary documents and quickly create an application.
We establish specialized teams for each project, and our systematized processes enable quick response.
We handle your applications swiftly and reliably.

* If a subsidy application is handled by someone other than an administrative scrivener, it may be in violation of the law.

Applicants who wish to utilize the subsidy request construction work from a construction company, and the construction company then applies to our company (see the diagram below).
Therefore, customers can use subsidies as a sales tool to make proposals to applicants (orderers).
