Quick answer. Energy savings certificates (CEE) help fund the energy renovation of tertiary premises: an obligated party pays a grant for insulation, heating or lighting works. With the sixth period opening on 1 January 2026, the application must be initiated before the works begin.
You are starting renovation works in your offices, your shop or your healthcare facility, and the bill adds up fast: insulation, replacing a boiler, LED relamping, heating controls. Many business owners find out too late that part of these works could have been funded by a grant, and that they lost it for failing to follow one simple rule. That is exactly what the energy savings certificates scheme is about.
In the tertiary renovation files we support, the most common mistake is not the choice of works: it is the timing. This guide explains how to fund your renovation with CEE, what changes with the sixth period in 2026, and the accounting and combination pitfalls to anticipate.
What is a CEE and who funds the grant?#
The energy savings certificates scheme rests on an obligation imposed by the State on energy sellers. These obligated parties (suppliers of electricity, gas, heating oil, fuels) must promote and fund energy savings among consumers. In return for operations carried out for households, businesses and local authorities, they obtain certificates proving they have met their obligation.
For a tertiary business, this translates concretely into a grant: an obligated party, or a delegate acting on its behalf, funds part of your energy efficiency works. You deliver the energy saving, the obligated party collects the corresponding certificate.
How a CEE works: obligated parties, operations, grant#
| Element | Role | What it means for you |
|---|---|---|
| Obligated party | Energy seller subject to the obligation (electricity, gas, heating oil, fuels) | It, or its delegate, pays the grant |
| Standardised operation | Standard works described in a standardised operation sheet by sector | Framed, faster process to set up |
| Specific operation | Works outside the standardised framework | Tailored file, heavier review |
| CEE grant | Funding paid in return for the energy saving | Income to record, to anticipate in the funding plan |
| Certificate (TWh cumac) | Proof of the energy saving given to the obligated party | Unit of measure of the scheme, not handled by the business |
Standardised operations are described in standardised operation sheets classified by sector: Offices, Education, Retail, Hospitality and Catering, Healthcare. If your works match one of these sheets, building the file is simpler. Otherwise, a specific operation remains possible, but the file is more technical.
What changes with the sixth period in 2026#
The sixth CEE period begins on 1 January 2026. The total obligation imposed on energy sellers is raised to around 1,050 TWh cumac per year, up around 27% compared with the 2023-2025 period. A quarter of this obligation, around 280 TWh cumac, must target households in fuel poverty.
For a business, this higher obligation keeps demand for certificates strong among obligated parties, which maintains the scheme as a real funding lever for your works. But the sixth period also strengthens the fight against fraud and windfall effects: controls are tighter, and a poorly framed file, or one set up after works have started, has little chance of succeeding.
Our view#
A CEE is not a grant you claim afterwards on the basis of invoices, like a tax credit. It is an incentive mechanism: the obligated party must play an active, incentivising role prior to your decision to commit to the works. The whole logic of the scheme rests on this precedence.
In practice, a business owner who signs the quote, starts the works, then looks for a grant, arrives too late. By far, this is the most common cause of lost grants we see. The right reflex is to deal with the CEE question when you are weighing up the quote, not when you pay the invoice.
How to obtain a CEE grant: the step-by-step process#
Timing matters more than anything. Here is the order to follow.
- Identify the eligible operation before any signature: check whether your works fall under a standardised operation sheet for your sector (Offices, Retail, Healthcare, etc.).
- Contact an obligated party or a delegate and obtain a grant proposal, before committing to any works.
- Formalise the commitment: the application and the incentivising role of the obligated party must be established before the works begin. This step secures your grant.
- Sign the quote and start the works once you have an agreement in principle.
- Have the works carried out by a professional and keep all supporting documents (quotes, invoices, certificates).
- Compile and submit the application with the required supporting documents.
- Receive the grant paid by the obligated party or delegate, and record it correctly.
Steps to obtain a CEE grant#
| Step | Timing | Point of attention |
|---|---|---|
| Check eligibility | Before the quote | Standardised sheet or specific operation? |
| Approach the obligated party / delegate | Before the quote | Compare grant proposals |
| Incentivising commitment established | Before the works | Step that conditions the grant |
| Sign the quote | After agreement in principle | Never sign beforehand |
| Carry out the works | After the commitment | Keep all supporting documents |
| Submit the file | After the works | Complete and consistent documents |
| Payment and accounting | On receipt of the grant | Treatment as income (grant) |
The underestimated risk: the precedence rule#
The most important practical rule fits in one sentence: the CEE grant application must be initiated before the works begin. The scheme has an incentivising role, and the obligated party must play an active, incentivising role prior to the commitment to the works. Starting the works before building the file means losing the grant, with no second chance.
In one file we handled, a company operating several retail spaces had planned to replace its lighting and its air handling unit. The works started as soon as the quote was signed, without approaching an obligated party beforehand. The potential grant, far from negligible against the budget, could not be recovered: precedence had not been respected. A simple check at the quote stage would have been enough to secure that funding.
In practice: accounting and combining aid#
The CEE grant received is income for the business. It is treated under the rules applicable to grants, and its allocation to the financial year deserves attention, especially when the related works are capitalised and depreciated over several years. The correct accounting treatment has a direct effect on the taxable result, which is why it is worth discussing with your chartered accountant before closing.
The CEE can also be combined with other forms of aid, but subject to conditions. Combination rules vary depending on the schemes involved, and aid received elsewhere may reduce or exclude the CEE grant on the same operation. It is better to map out all the aid you are considering before finalising the funding plan, rather than discovering an incompatibility at application time.
If your works also involve the VAT applicable to renovation, or if you are subject to the tertiary decree obligations, these topics are managed together. See our guide on the tertiary decree and the OPERAT scheme and our analysis of the reduced VAT rate on renovation works.
Points of attention for 2026#
- Precedence of the application: no grant without the obligated party's commitment before the works begin.
- Tighter controls: the sixth period strengthens the fight against fraud and windfall effects; an incomplete or inconsistent file is a risk.
- Choice of obligated party or delegate: grant proposals vary; compare before committing.
- Quality of supporting documents: quotes, invoices and certificates must be complete and consistent with each other.
- Combining aid: check compatibility with other schemes before finalising the funding.
A structured energy efficiency approach, for example through an ISO 50001 certification to steer your energy performance, strengthens the consistency of your files and the control of your consumption over time.
Checklist before starting your works#
- Works matched against a standardised operation sheet for my sector
- Obligated party or delegate approached before the quote
- Incentivising commitment of the obligated party established before the works begin
- Funding plan integrating the grant and other compatible aid
- Supporting documents kept (quotes, invoices, certificates)
- Accounting treatment of the grant anticipated with the chartered accountant
Frequently asked questions
What is a CEE?+
An energy savings certificate is a scheme that requires energy sellers (electricity, gas, heating oil, fuels), known as obligated parties, to fund energy savings among consumers. In return for operations carried out, they obtain certificates proving they have met their obligation.
Can a tertiary business benefit from a CEE grant?+
Yes. A tertiary business can have energy efficiency works (insulation, heating, lighting, controls) funded by a grant paid by an obligated party or a delegate. Standardised operation sheets exist by sector: Offices, Education, Retail, Hospitality and Catering, Healthcare.
Must the application be filed before the works?+
Yes, and this is the decisive rule. The application must be initiated before the works begin: the scheme is an incentive, and the obligated party must play an active role prior to the commitment to the works. Starting the works before building the file means losing the grant, with no second chance.
How is the CEE grant calculated?+
The grant depends on the energy saving generated by the operation, expressed in certificates, and on the proposal of the obligated party or delegate you choose. Amounts vary from one player to another. Comparing several proposals before committing helps you better value your works.
Can the CEE be combined with other aid?+
The CEE can be combined with other aid, but subject to conditions. Combination rules vary depending on the schemes involved, and aid received elsewhere may reduce or exclude the grant on the same operation. Check compatibility before finalising your funding plan.
How is the CEE grant recorded in the accounts?+
The grant received is income, treated under the rules applicable to grants. Its allocation to the financial year deserves attention, especially when the works are capitalised and depreciated over several years. The treatment chosen has a direct effect on the taxable result.
When does the sixth CEE period start?+
The sixth period begins on 1 January 2026. The total obligation is raised to around 1,050 TWh cumac per year, up around 27% on 2023-2025, including around 280 TWh cumac targeting households in fuel poverty. This period strengthens the fight against fraud.
