1. Four things to watch
In order of importance, and the first is the most pressing at present. It concerns transposition of the directive.
| What to watch | State |
|---|---|
| Transposition of Directive 2024/1275 into Estonian law | the deadline was 29.05.2026, the state must be checked in the legislation |
| Versions of the three energy performance regulations | last changed 01.06.2025 |
| Update of the cost-optimal methodology | see what remains unsettled |
| The five-year update cycle | the next change is known as a principle |
For the first, the deadline has passed, so the answer cannot be assumed: it has to be read from the legislation in force. The position must be checked in an official source.
2. One requirement that is not observed in practice
An observation that is at once legal and commercial. A certificate is compulsory on a sale.
According to information published by the Ministry of Climate, an advertisement for the transfer for consideration or the letting of a building or of a separately usable part of it must contain the energy certificate data, including the energy class, and the requirement follows from the Building Code. The requirement also applies on letting.
According to professional sources this part of the law has not so far been properly observed, and property portals rarely display the energy class alongside a listing. This inconsistency is unlikely to persist, since the directive's aim is precisely the informed choice of the consumer, which makes enforcement of the requirement more likely over time.
3. What a certificate actually affects on the property market
The assessment in professional sources is honest here, and therefore useful. Practice is still taking shape.
A direct price effect is hard to isolate, because the energy class almost always goes together with the state of renovation, the year of construction and the heating system. A buyer does not buy a class letter, they buy a heating bill.
The indirect effect is nonetheless clear in three places: running costs, green loans and the buyer's borrowing capacity. A poor class means a higher heating bill, which reduces the buyer's borrowing capacity, tying the energy class to the buyer's ability to finance the purchase, the same pattern as with the building register entry.
4. Why a certificate is also a condition of financing
Three situations in which the absence of a certificate blocks the way. They concern a sale, a letting and a procedure.
| Situation | Note |
|---|---|
| Applying for a building permit for a new or substantially reconstructed building | a condition of the procedure |
| Sale and letting | the advertisement requirement and the buyer's check |
| Support measures | a certificate is a precondition according to professional sources |
The third is particularly relevant for apartment buildings, since renovation grants have been substantial and opened in cycles. The conditions and deadlines of grant rounds change, and they must be checked with the body awarding the grant rather than from general overviews.
5. What changes without announcement
Two things move quietly, and neither change is news. They are the methodology and the limit values.
According to information published by the Ministry of Climate, the base-year climate data in energy calculations have been replaced, using data for the period 1990 to 2020 instead of 1970 to 2000, and normal-year degree days are being updated. The second is professional standards, which determine who may issue a certificate.
Both affect the calculation and its validity, although neither is announced separately. The change must be checked independently.
Summary and four practical rules
Four things need watching, the most pressing being the state of transposition of Directive 2024/1275, since its deadline of 29 May 2026 has passed. The requirement to state the energy certificate data with the class in an advertisement follows from the Building Code but has not been properly observed, and that inconsistency is unlikely to persist. A direct price effect is hard to isolate, since a buyer does not buy a class letter but a heating bill, yet the indirect effect runs through running costs, green loans and borrowing capacity.
Four rules: check the state of transposition before relying on future requirements. Include the energy class in advertisements, since the requirement holds even where it is widely ignored. Explain the indirect effect on borrowing capacity to the client, which is more persuasive than the class letter. Check grant conditions with the awarding body, not from general sources.
