- De Minimis Owner's Declaration of Responsibility (in case of rental/free concession) completed with the details of the Owner of the property.
- In the case of co-owners, the De minimis Declaration is completed and submitted by all co-owners (usufructuaries and full owners). In the “Other Documents” section of the digital platform of the Programme, the other documents are posted in addition.
- In the case where the De Minimis Declaration is signed by a proxy instead of the owner, for the completeness of the application and the correct examination procedure, it is necessary to present the corresponding power of attorney document. The power of attorney should explicitly state the right of the attorney to sign on behalf of the owner for transactions related to public bodies, and should explicitly cover the signing of responsible declarations such as the De Minimis Declaration.
- If the owner of the property is a legal entity, the Declaration must be completed by the legal representative of the company.
- If the owner has died and the acceptance of the inheritance has not been completed, the owners until the formal publication of the will are considered the intestate heirs of the deceased (usually spouse and children, or any other relationship provided for by the law of succession). Therefore, these persons may proceed to make a Declaration of Ownership for the purposes of the Scheme.
- Owner's Declaration of Consent (in case of rental/free concession) completed with the details of the Owner of the property.
- In case of co-owners, the Informed Consent Form is submitted by all co-owners (usufructuaries and full masters). In the “Other Documents” section of the digital platform of the Programme, the other documents are posted in addition.
- If the owner has died and the acceptance of the inheritance has not been completed, the owners until the formal publication of the will are considered the intestate heirs of the deceased (usually spouse and children, or any other relationship provided for by the law of succession). Therefore, these persons may proceed to make a Declaration of Ownership for the purposes of the Scheme.
- Certificate of Disability (in case of a disabled member).
- Electricity Provider Account (Last 2 months).
- Income tax declaration (E1), of the tax year 2023, showing the main/secondary residence where the eligible equipment is installed.
- In the case of family income where the Spouses/MPAs submit separate tax returns, the attachment of the Spouse's/MPA's income tax return (E1) is required in the “Other Documents” section of the digital platform of the Programme.
- Certificate of Family Status, in the case of three (3) or more dependent children.
- In the case of a foreign national, the birth certificates of the children must be attached. In the “Other Documents” section of the digital platform of the Programme, the other documents are uploaded in order to confirm the parental relationship and the number of dependent children.
- Lease information declaration real estate property of the Hellenic Revenue Service (Property Lease), if the house is rented.
2.8 I am a disabled person or there is a disabled person in my family. What do I have to submit in order to be considered for the Programme?;
To count towards the classification criterion, an applicant with a disability or dependent child with a disability greater than or equal to 67% must provide an opinion or certificate from a disability certification board or other competent authority which by law continues to exercise its powers.
2.9 I applied for funding. When will I receive the corresponding cheques for my purchases?;
Beneficiaries will be able to receive and use the cheques after the affiliation decision.
2.10 What are cheques? Will I be reimbursed any amount of money? How will I repay the purchase of the new equipment?;
No money is refunded. Once the application is approved and eligibility is established, Program Vouchers are sent electronically.
The first cheque is used for the purchase of new Category A & B equipment, while the second can subsidise (optionally) the cost of additional services (e.g. installation costs, consumables, piping, valves, brackets, fittings, smart system (timer), etc.).
Cheques are not issued in physical form, but are assigned to unique codes, which are sent to the online account of the platform where the application was submitted, as well as to the confirmed email address. These cheques are cashed by an approved supplier who is included in the Supplier Register.
By providing the cheques to each supplier, part of the price of the equipment and the cost of additional installation work is covered. Therefore, payment of the remaining value is required by own means (cash, card, instalments, etc.).
2.11 What value does each cheque represent? What is the final amount of the grant I will receive?;
There is no single amount for every case.
The maximum value of the cheque is determined by a number of factors, including but not limited to the subsidy rate (from 50% to 60%) you are entitled to and the selling price of the product.
If the selling price of the Solar Water Heater exceeds the manufacturer's Suggested Retail Price (RRP) (which you will know from April 2025) then you are entitled to the maximum subsidy rate on the RRP.
Similarly, the maximum value of the cheque for the cost of carrying out the necessary additional work varies according to the grant rate you are entitled to (from 50% to 60% depending on your income category).
The maximum values (maximum amount of grant) per case are available in Tables 3 and 4 of paragraph 2.4 the Programme Guide.
2.12 What if I lose or forget my cheque code?;
The cheque code is stored in your online account, at the point where you submitted your funding application, on the digital platform of the Programme. In addition, check codes will be sent to the email address provided at the time of application submission to the Program.
2.13 Can I transfer my cheque to someone else if I do not use it?;
No way. Checks are personal and pertain to the application submitted and approved (eligibility, income criteria, residential address of establishment, etc.).
2.14 What happens if someone else finds out my cheque codes? Could they use them? Would I have to produce some form of identification for verification at the time I make a purchase?;
Knowing the codes of the cheques does not in itself allow a third party to use them. At the time of purchase, a one-time use code (OTP) valid for a few minutes and sent to your personal email address, which in turn is confirmed at the time of application.
In other words, double confirmation is required and the person making the purchase should know their personal details (VAT number, passwords), as well as have timely access to their confirmed email address.
2.15 I visited a shop to make a purchase, but was informed that it does not participate in the Programme. Is he not obliged to accept the cheque I present to him?;
Not every supplier of eligible equipment is required to participate in the Program. Those who wish to do so must apply and follow specific procedures.
A list of all (at any given time) approved suppliers is published on the Programme website.
2.16 When I applied, I chose not to apply for a subsidy for additional services. Can I be subsidised for these by the Programme?;
The subsidy for additional services is not possible if you have chosen not to apply for it when submitting the application on the digital platform of the Programme. The field «Do you wish to subsidise the Supplementary Services?» is mandatory and the option you indicate («Yes» or «No») is entered in your application. Once your application has been finally submitted, it cannot be edited. Therefore, if you have indicated that you do not wish to receive a grant, there is no possibility of a grant afterwards.
Otherwise, the service check may be cancelled even after the final submission of the application.
2.17 All the fields of my application appear to be filled in but the «Submit» option of the application is not active. What should I check regarding the correctness of the application?;
To activate the submission feature, you need to check the following fields:
- No. Dependent children : If you have dependent children, enter the corresponding number or, if you do not have any, enter “0” (zero).
- Power supply: Check that you have answered the questions «Is the Power Supply Active?», «Is the Power Supply Domestic?» «Is the electricity supply residential?» and "Is the electricity supply communal?" and "Is the electricity supply communal?".
- No. Power Supply No: Check that the Power Supply No. Check that you have filled in the first 11 digits and the hyphen in the Power Supply Number. (e.g. 111111111-11).
- A.D.T. / Passport: Check that the ID number does not contain any spaces and is in Greek characters.
- Individual and family income: Check that the individual and family income fields are both filled in (without decimals).
- Make sure that you have accepted the terms and conditions of the Programme and that you have attached all the required documents.
The application has been successfully registered when a confirmation email is sent to you and it is in the “For Evaluation” status.
2.18 What happens if I have submitted an incorrect or incomplete document in my application?;
After the final submission of your application, it cannot be processed. During the evaluation of your application and in certain cases where it is found that any of the documents submitted is incorrect, incomplete or not clear (e.g. blank document, incorrect file, unreadable scan), you will be asked via the Programme's digital platform to re-attach the correct document or any additional supplementary information.
The applicant must post the correct document on the digital platform within seven (7) calendar days from the date of the electronic notification.
2.19 Where can I find the model Responsible Declarations required for my application?;
The templates of the Responsible Declarations are available in the Programme Guide and in the «Documents» section of the Programme's digital platform. Applicants can download, complete and submit them according to the instructions.

Therefore, the Application for Participation in the new «Change Heating System and Water Heater» Programme is necessary, even for suppliers who were registered in the supplier register of the previous «Recycle - Change Water Heater» Programme.
3.5 Will I have time to submit an Application Form and have it approved before the start of the Programme? Is there a deadline?;
There is no deadline for suppliers to submit applications to participate. New suppliers may be approved throughout the duration of the Programme.
The Application Form is very simple and can be completed in a few minutes, while the required documents are also simple and are usually issued instantly, via the internet.
At the start of the Programme, there may be a few days of congestion if all shops apply at the same time. However, thereafter, applications will be approved or rejected.
3.6 Which suppliers can submit a product declaration to the Equipment Register and what are the stages of the product declaration?;
The product declaration may be submitted by indirect suppliers, i.e. manufacturers (or a subsidiary/associated company), agents, importers and distributors, without direct dealings with the beneficiaries. It should be noted that a declaration by a retailer is not allowed unless the retailer has one of the above roles for the eligible equipment.
The procedure includes:
- A statement of product characteristics, models and types, including the following information: Product Code, Manufacturer, Model/Name, Product Description and Supplier Information.
- Submission of the necessary documentation proving the eligibility of the product, through the listing of an official product website, where the specifications and description of the product are presented.
- Declaration of Maximum Suggested Retail Price (Reasonable Cost). The retail price must be less than or equal to the «maximum suggested retail price» declared by the manufacturer or supplier.
After registration, the Programme proceeds to evaluate the declared products and elements in order to ensure that the products comply with the minimum requirements set out in the Programme Guide.
Products that meet the requirements are registered in the Register of Approved Equipment, which is accessible to beneficiaries and suppliers.
3.7 Is it necessary to re-declare the models of equipment to be made available through the Programme, if they are already included in the Single Register of Approved Equipment?;
Re-declaration is not necessary. If the equipment has already been declared and approved, it can be made available by any approved supplier without the need for a new approval, as it is already registered in the Single Register of Approved Equipment.
3.8 How do I know if a client of mine is subsidised by the Programme? Do I have to provide a document?;
He will report it to you himself. No document is required, only that he knows his VAT number, the code of the cheque, and that he brings his mobile phone device to confirm the cashing of the cheque by email.
The supplier can enter the code of the cheque in the digital platform of the Programme in order to check if it corresponds to a valid and available cheque. He also enters the VAT number, the code of the cheque and the one-time code that will be sent to his mobile phone at that moment, in order to bind the cheque for the subsequent payment of the document he will issue.
For more information please see Section 6.2 the Programme Guide.
3.9 The customer wishes to proceed with an order, but I need a few days to receive the new equipment from my supplier and deliver it to the customer. What should I do with the check in the interim? Do I make a declaration on the digital platform?;
Once an order has been placed, the cheque must be committed on the Programme's digital platform. For this purpose, the VAT number, the cheque code and the one-time use code, which will be sent at that time to the customer's e-mail address, must be entered in the platform in order to bind the cheque.
The cheque remains blocked for a period of 30 days, within which the sale process is expected to be completed. The freeze ensures that during this period, the beneficiary cannot use the same cheque to make a parallel purchase with a subsidised purchase from another supplier.
For more information please see Section 6.2 the Programme Guide.
3.10 My customer changed his mind and asked to cancel the order before receiving the new solar. In the meantime, however, I had pledged his cheque. What should I do?;
The cheque can be returned to the customer and used at another retailer if the customer wishes. In this case, the retailer proceeds to release the cheque immediately via the digital platform before the 30 days have elapsed (without waiting for automatic release).
3.11 How much will the customer ultimately pay? Can I request payment of the total value of the product (new equipment) and later refund the subsidy amount to the customer with a credit voucher after I am paid by the Program? At what point in time can I bill my customer?;
The amount that the customer has to pay is only the amount that is less than the grant (i.e. the total price including VAT minus the final value of the cheque). The value of the cheque is considered as a method of payment that partially pays off the sales document. Once the cheque is issued, the equivalent amount is deemed to have been paid and the customer is only required to pay the balance of the payment.
As for the remaining amount (other than the grant) paid by the customer, it is paid in the ways and at the time chosen, in line with normal commercial practice.
3.12 The customer wants to purchase eligible equipment together with a 24 instalment installation service. Which of these do I state on the sales document?;
In the case of a purchase of a product which includes additional and eligible services, these should be invoiced separately (e.g. on a different line of the same document or on a separate document) and in any event, should not be included in the price of the basic product on which the aid is to be calculated. The sales document must be signed by both the supplier and the beneficiary and posted on the Programme's digital platform in order to proceed with the payment of the supplier by the Programme.
Especially with regard to the service cheque, the cashing cannot precede the successful cashing of the corresponding product cheque (it must occur at the same time or after it).
All of the additional services must be included on a single document (from a single supplier) in order to be eligible for a service voucher.
The subsidised sale price of the new equipment and the additional services must correspond to a cash price, as any interest accruing after settlement (instalments) is not subsidised. Where payment is made on the basis of instalments, the total amount (value) in cash should be recorded and declared in each transaction, separately from any other charges (e.g. interest and envelope charges).
For more information please see Section 3 the Programme Guide.
3.13 How and by whom will I be paid for eligible equipment?;
For each new purchase of eligible equipment, the supplier cashes the customer's equipment check (on the Program's digital platform), which covers a portion of the cost of the equipment provided and invoiced. The check amount due will be collected by the Paying Entity beginning in the calendar month following the month in which the check is successfully cashed.
For each redemption, a legal sales document is required, which must be signed by both the supplier and the beneficiary. The sales document is posted by the vendor on the Program's digital platform in order to proceed with the vendor's payment from the Program.
3.14 Does the service voucher (installation, consumables, etc.) include the cost of the on-site survey by a workshop that is usually required for the installation of a heat pump and solar water heater system?;
The Guide does not explicitly define the cost of the on-site survey. If the client wishes to include the on-site survey in the service package, this is not prohibited, as the examples of additional services are indicative.
3.15 In case a beneficiary wants to redeem the product voucher to one supplier and the service voucher to another, which of the two invoices the cost of transporting the product? Can the service voucher be redeemed in parts and have two invoices from different suppliers?;
