More than 350,000 applications for the heating allowance have been submitted since the myHeating application opened on the myAADE digital portal. The allowance applies exclusively to the applicant’s main residence, and each eligible recipient may choose just one type of subsidised heating.

For those experiencing difficulties with the application process, the Independent Authority for Public Revenue (AADE) has published a detailed guide answering the questions most frequently asked by eligible recipients. In addition to the general criteria and terms for receiving the allowance, it clarifies issues such as electricity subsidies where there is no active connection or a shared meter is used, the application process for residents of apartment buildings, and the requirements for purchases of heating oil from petrol stations and other suppliers.

In particular, the AADE guide clarifies the following:

1. Which credentials do I need to log in to the heating allowance application?

Applications are submitted through the myHeating application on the myAADE digital portal, using personal TAXISnet credentials.

2. Which credentials do I need to log in to the “My Receipts” application to enter fuel purchase receipts?

Users can log in to the application only with their personal TAXISnet credentials.

3. What is the deadline for applying for the heating allowance?

The application deadline is 4 December 2026.

4. Can I apply without having provided a bank account IBAN?

No. Before finalising the application, the eligible recipient must have entered a bank account number on the «IBAN Account Declaration» platform on the myAADE digital portal. They must be the account’s sole or joint holder, and it must be the account into which they wish the heating allowance to be paid.

5. My account’s IBAN is inactive. How can I correct it?

The IBAN must be active and registered through the myAADE platform. To correct it, the eligible recipient should select «REGISTRY & CONTACT» on myAADE and log in using their personal TAXISnet credentials. They should then enter the new account number in the «IBAN Account Declaration» field.

6. Which heating fuel purchases are eligible for the 2026-2027 winter season?

The heating allowance covers purchases of heating oil, illuminating kerosene (blue kerosene), natural gas, liquefied petroleum gas, firewood, biomass (pellets), thermal energy supplied through district heating and electricity.

Purchases of eligible fuels must be made between 1 October 2026 and 31 March 2027. Heating oil purchases are eligible from 15 October 2026, when it becomes available for sale.

As an exception, firewood and biomass (pellets) must be purchased between 1 June 2026 and 31 March 2027.

Each eligible recipient may receive a subsidy for only one type of heating fuel.

7. For which heating fuels do I need to enter receipts through the “My Receipts” application?

Receipts must be entered in the application for all types of heating fuel, except heating oil and electricity.

8. What is the deadline for entering receipts for other fuel purchases?

For purchases relating to consumption from 1 October 2026 or, specifically for firewood and biomass (pellets), from 1 June 2026 to 31 March 2027, receipts must be entered by 29 April 2027, provided the relevant documents were issued by 15 April 2027.

For natural gas and thermal energy consumption through district heating, receipts must be entered by 15 July 2027, for documents issued by 30 June 2027.

9. When will the heating allowance be paid into my bank account?

The heating allowance is paid in advance, followed by one or more instalments.

Those who received the allowance for the 2025-2026 winter season will receive an advance of 60% of the total amount paid to them in the previous winter season by 23 December 2026.

For applicants who were not eligible the previous year, the advance is set at 50% of the corresponding amount determined by administrative decision A.1230/2026 (Government Gazette B’ 6569/30.10.2026).

In all cases, the advance cannot be less than €80.

The remaining allowance will be paid by 28 May 2027, for consumption between 1 October 2026 and 31 March 2027. The amount is calculated after deducting the advance, on the condition that the total allowance does not exceed 50% of the invoiced purchases for the relevant period or fall below €100.

If the remaining amount after deducting the advance is negative, it is treated as zero and no additional amount is paid beyond the advance.

An additional payment is предусмотрed by 30 July 2027 specifically for natural gas, thermal energy supplied through district heating and electricity.

10. What do I need to do to ensure my heating oil purchase receipt can be cross-checked?

The eligible recipient must give the heating oil supplier the correct details — their tax identification number (TIN) and electricity supply number — so that the purchase document is issued correctly.

These details must be the ones used, or to be used, in the application and are shown on the application confirmation. The confirmation appears in the list of applications when the user selects the blue PDF icon.

The heating oil purchase document must be issued under the applicant’s TIN — that is, the person whose TAXISnet credentials were used, or will be used, to submit the online application.

For an apartment building, the heating oil purchase document must be issued:

  • Either under the apartment building’s TIN, if it has one.

  • Or under the TIN of the person whose TAXISnet credentials were used to create and activate the apartment building profile and to whom the application relates.

In addition, the heating oil purchase document must state the correct electricity supply number for a standalone house. For an apartment building, it must state the correct electricity supply number registered as the building’s common supply in its profile.

11. What do I need to do to ensure a purchase receipt is cross-checked for fuels other than heating oil and electricity?

The eligible recipient must enter their purchases in the “My Receipts” application.

The required details are:

  • The number of the receipt for the fuel purchase or thermal energy consumption through district heating.

  • The amount or value of the transaction.

  • The TIN of the business selling the heating fuels.

  • The name of the business selling the heating fuels.

If eligible recipients pay their heating costs through shared building charges, they must also enter:

  • The number of the receipt for payment of the shared charges or, alternatively, the number shown on the payment notice, if no payment receipt has been issued by the time the application is submitted.

  • The TIN of the building manager, the person representing the apartment building or the company managing it.

  • The amount attributable to the eligible recipient.

12. I applied using my personal TAXISnet credentials, but the fuel purchase documents show my spouse’s TIN. Will this cause a problem with cross-checking the details?

Cross-checking will be prevented only if the documents relate to the purchase of heating oil.

For all other types of heating fuel, the details will be cross-checked without any problem.

If a problem arises with a heating oil purchase, the eligible recipient must take one of the following two steps in good time:

  • Before the application deadline of 4 December 2026, withdraw their application and have their spouse submit a new application using their own TAXISnet credentials.

  • If fewer than 14 days have passed since the heating oil was purchased, ask the supplier (petrol station operator) to change the buyer’s TIN to their spouse’s TIN.

13. How many applications can I submit by 4 December 2026 for the heating allowance for the 2026-2027 winter season?

The application does not limit the number of applications an eligible recipient may submit. However, they must first withdraw any previous active application before submitting a new one.

Applications must relate exclusively to the eligible recipient’s main residence.

14. I bought more than one type of fuel during the 2025-2026 winter season. Can I submit multiple applications, one for each type of fuel?

No. Under the relevant decision, each eligible recipient may receive a subsidy for only one type of heating fuel.

15. As the manager of an apartment building, do I need to create an apartment building profile if the building uses a fuel other than heating oil or electricity?

No. In that case, all eligible recipients can simply submit applications as they would for standalone houses.

The application allows users to create an apartment building profile, but this is not required. Heating cost allocation shares are included in the amount attributable to each eligible recipient, who enters them through the “My Receipts” application; the building manager does not do this.

16. As the manager of an apartment building with a shared heating oil boiler, what do I need to do about the heating cost allocation shares and the building’s TIN?

Where there is a shared heating oil boiler, the building manager or representative enters:

  • Details of the apartments in the apartment building or small apartment block.

  • Each apartment’s share of the heating costs.

It is mandatory to declare every apartment’s share of the heating costs, so that the profile reflects the building as a whole. A single allocation must be agreed for the entire year.

The total shares for all apartments must add up to 1,000, and the apartment building profile must be saved as final before it can be used to submit applications.

If the building manager changes during the period in which the heating allowance is granted, the guidance in the next question applies.

For heating oil purchase documents, the TIN and the number of the shared electricity supply must match the details entered under “Heating Share Management”.

If the apartment building has been issued a TIN and the manager wants heating oil purchase documents to be issued under it, they must enter the building’s TIN in the profile by selecting the relevant “Set TIN” link.

However, even if an apartment building TIN has been set, residents’ applications will show the TIN of the manager or representative.

17. What should be done if the building manager changes?

If the manager changes before the application deadline and no purchase documents have been issued under the previous manager’s TIN, the new manager must create a new apartment building profile.

Residents and owners will submit their applications through the new profile, which will be created under the new manager’s TIN. The new manager must save the profile as final before it can be used for residents’ applications.

However, if the manager changes after 4 December 2026, when the application deadline has passed, or if documents have already been issued under the previous manager’s TIN during the current period, the new manager’s TIN must be entered in the apartment building profile.

This declaration is solely for cross-checking documents issued under the new manager’s TIN for the current 2026-2027 period. A new apartment building profile must be created by the new manager for the following year.

18. As the manager of an apartment building, how can I change the details shown in the residents’ allocation, specifically the “Surname” and “Resident’s first name” fields?

The apartment building details can be changed provided no applications have been submitted for the building during the current period.

If at least one application has already been submitted, changes can be made only to apartments for which no heating allowance application has been submitted.

The names shown are indicative and do not affect the application. If the apartment building profile shows the names of previous residents, the manager should tell any new resident wishing to apply which apartment number to select in the profile, even if it displays the previous resident’s name.

19. Which credentials do apartment building managers need to log in to the “Heating Share Management” application?

Managers log in using their personal TAXISnet credentials.

For legal entities and property management companies, the personal TAXISnet credentials of the authorised legal representative are used. The legal entity is then selected from the “Select Declarant” menu.

20. There is no manager for the apartment building, or there is no shared electricity supply number. What details should be provided?

If there is no manager, all residents or owners must agree on who will take on the role. That person will create the apartment building profile through the myHeating platform, entering the apartments, heating cost allocation shares and other required details.

If there is no shared electricity supply, all residents or owners must also agree on which electricity supply number — usually the manager’s or representative’s — will be used as the shared supply and entered in the apartment building profile.

21. Each apartment in our building has its own boiler. Should it be registered as an apartment building, or should each resident apply as if they lived in a standalone house?

In this case, each resident or owner must submit a separate application as if they lived in a standalone house. They must also buy their heating fuel using separate purchase documents.

22. We live in a two-unit building and have one electricity supply. Can both of us apply for the electricity heating allowance?

The same electricity supply number cannot be used by more than one eligible recipient for the same period.

23. Does the natural gas company need to take any action for me to receive the heating allowance?

No.

24. I am eligible for the Social Residential Tariff (KOT). Can I also receive the heating allowance for electricity?

No. Recipients of the Social Residential Tariff (KOT) on the application deadline are excluded from the heating allowance for electricity. The Hellenic Electricity Distribution Network Operator (HEDNO) checks recipients’ details and excludes those covered by the KOT.
