What the scheme covers
The scheme supports works improving the energy performance of a dwelling, as well as sustainable construction.
The items covered concern the envelope and the equipment, notably insulation, replacement of external joinery, heating systems and installations producing renewable energy.
A supplement may be added to the base amount, in the form of an uplift.
A specific interest subsidy also exists for loans intended for energy improvement, covered in the article on financing support.

The change in payment arrangements
A development that changes the project's cash flow, not its cost. Payment now falls at a different moment.
Since the start of 2026, the grant relating to photovoltaic installations is deducted directly from the final invoice by the installer.
It applies to photovoltaic installations and, where applicable, in combination with a domestic battery.
The beneficiary therefore no longer has to advance the sum and wait for payment from the State, which amounts to pre-financing.
This arrangement is a relief rather than a payment, a distinction covered in the article on the four families of schemes, and it must be reflected as such in a funding plan.
What has been withdrawn
A point to know before proposing a technical solution. Not every solution qualifies for the same level of support.
The improvement grant for installing boilers running on fossil fuels has ended, in line with European requirements and climate objectives.
A project replacing an installation with a fossil-fuel solution therefore no longer attracts this support.
This withdrawal forms part of a broader movement that also touches the value added tax treatment of certain installations, and which should be checked case by case.
Consequence for design: the choice of heat generation system affects financing, and not only running costs.
How it interacts with the other schemes
Three points of method.
Combining with the reduced rate of value added tax is possible, each scheme bearing on its own object.
Combining does not mean overlaying on the same item, as the article on combining schemes and its limits recalls.
The timetables differ. Tax approval is applied for before works; energy support has its own procedure and its own documents.
Running both processes in parallel is therefore the rule, not the exception.
What to check before works
Four points.
The eligibility of the items envisaged, not all works being covered.
The technical requirements attaching to each item, which condition the grant.
When the application is made and by whom, some steps being carried by the installer.
The state of the scheme at the date of the project, it having undergone a transition and being capable of further change.
What this means for a professional
Four rules.
Check the state of the scheme before each project, rather than relying on acquired knowledge.
Flag the withdrawal of support for fossil-fuel installations from the design stage.
Reflect pre-financing in the funding plan, cash flow differing according to the arrangement.
Run the tax and energy processes in parallel, their timetables being distinct.
This article reflects the state of the schemes at the date of checking and serves professional orientation. It does not replace consultation of the responsible ministry.
