Getting your heat pump on the ISDE list

What the reporting code list is

The reporting code list is an overview of heat pumps that have already been assessed within the subsidy scheme. Each approved device receives a reporting code that private and business applicants enter in their application. If your device is not listed, the applicant must provide the documentation themselves.

For you as a supplier, this is the difference between a product that quickly ends up in a quote and a product that first causes discussion. When in doubt, installers and advisors choose the device they can offer without extra work.

The list is updated regularly. Your product information must therefore adapt whenever you modify a version or withdraw it from the market.

Why a reporting code sells

A device with a reporting code provides the installer with certainty, the advisor with speed, and the end customer with confidence. No additional documentation needs to be requested. Furthermore, there is less chance of discussion regarding specifications during the processing of the application.

An application can sometimes still be submitted without a reporting code. The applicant then provides additional documentation themselves. If the device then turns out not to meet the conditions, a rejection will still follow. That risk lies with your installer’s customer, who will subsequently attribute it to the product.

Which requirements the device meets

The scheme sets requirements for the type of heat pump and its performance. Since January 1, 2024, a minimum energy label of A++ applies to the device in most cases. Air-to-air heat pumps fall outside the scheme, unlike air-to-water, ground-to-water, and water-to-water heat pumps.

In addition, you must substantiate the performance: space heating, domestic hot water where applicable, sound power level, and the refrigerant used. These values must be identical in all documents.

Please note that the conditions are determined per subsidy year and are therefore subject to change. Separate rules may also apply to devices with higher capacities. Therefore, always check the current reporting code list and the conditions at the RVO before compiling a file.

The label of the device, not the package

A common mistake is providing a package label, which is the combined label of the heat pump with a controller or solar water heater. The energy label of the heat pump itself is required. These two labels show different values, which is immediately noticed during the assessment.

The documents you provide

A complete file contains the energy label of the device itself, the product fiche, the calculation of the technical data, and the test report where required. This also includes the EPREL registration number with the product link and the substantiation of refrigerant and sound power level.

Energy label of the heat pump itself. Not the package label.
Product fiche or product data sheet. The official product information with the technical specifications.
Calculation of technical data. Substantiation of performance for space heating and, where applicable, domestic hot water.
Test report. Where required according to EN 14825 for space heating or EN 16147 for domestic hot water.
EPREL registration number and product link. To the registered model.
Substantiation of refrigerant and sound power level. The specified values must follow from documentation.
Declaration of Conformity. In which the applicable legislation is mentioned.
Declaration of equivalence and photo of the rating plate. When your model number differs from the one in the test report.

How EPREL registration works and who must perform it is explained in our article on EPREL. The registration number is the final step of that process, not a separate action.

Do you want to know if your file is complete?

Briefly let us know which device it concerns and what documentation you have available. We will contact you regarding anything that is still missing.

How the registration process works

You start by testing the technical requirements against the current conditions at the RVO. Then you collect the documents and check whether the brand name, type number, and performance values are identical everywhere. Only when everything matches do you submit the file.

This consistency check is the most important step. In many organizations, sales, engineering, and marketing work with different versions of the same product information. The assessor sees that difference; you do not.

The mistakes that cause delays

Virtually all delays stem from small discrepancies between the submitted documents. A package label instead of the device label. A product fiche that deviates from the data in EPREL. Or model numbers that differ per document without anyone noticing.

Package label instead of device label. Different values, immediately visible during assessment.
Fiche and EPREL diverge. The assessor can consult both and will compare them.
Different model numbers. Without a declaration of equivalence and rating plate photo, the link cannot be established.
Missing substantiation. Sound power level and refrigerant are specified without a document supporting the value.

What you need to arrange

First, check whether the device meets the current conditions for this subsidy year. Then collect the documents and compare them for brand name, type number, and performance values. Resolve any discrepancies before submitting, as a second round takes weeks.

Consult the current reporting code list and conditions at the RVO. These are determined annually.
Ensure the EPREL registration is complete, as the registration number belongs in the file.
Place the label, fiche, test report, and EPREL side by side and compare every value.
In the case of a differing model number, arrange a declaration of equivalence plus a photo of the rating plate.
Appoint one person to manage the product data, so that departments do not work with different versions.
