Greece’s New Minimum Energy Standards (MEPS): What Owners Must Know

An owner of a 1980s villa on Corfu treats energy efficiency as a comfort choice, something to do eventually. Across the EU that choice is being removed. Minimum energy performance standards for existing buildings are coming, Greece is transposing them, and the building that is comfortable to ignore today becomes harder to sell or let tomorrow. The owners who plan around this early upgrade on their own terms. The ones who wait do it under a deadline at full cost.

The driver is the recast EU Energy Performance of Buildings Directive, directive 2024/1275. It introduces minimum energy performance standards, known as MEPS, for existing buildings, it has banned subsidies for standalone fossil-fuel boilers since the start of 2025 with a phase-out toward 2040, and it requires solar on new non-residential buildings from the end of 2026. The deadline for member states to transpose it was 29 May 2026, and Greece is finalising this through a revision of its KENAK building energy code, so the exact national thresholds and trigger points should still be verified against the Greek law as it lands. At EU level the direction is already set: the worst-performing non-residential buildings face renovation milestones of 16 percent by 2030 and 26 percent by 2033, and member states must set a national trajectory for the residential stock.

Why acting ahead of the standards is cheaper

Minimum energy performance standards point toward a future where upgrades may shift from optional to required, though the exact obligations are not yet fixed. That uncertainty is itself a reason to act early rather than wait for a deadline. Today the grants cover up to 80 percent of eligible work, up to around 24,800 euros, with an owner contribution near 5,000 euros, and demand for the work is still moderate enough to keep prices reasonable. When standards tighten and owners move in a rush, demand and contractor pricing climb together. Acting ahead secures the subsidy and the lower cost.

What MEPS Means in Practice

MEPS works by setting a minimum rating a building must reach, often enforced at trigger points such as sale or lease, and by progressively lifting the floor over time. For an owner, the practical effect is that the worst-performing homes, the ones with a low energy performance certificate, come under pressure first. That is most of the older, pre-2011 stock that foreign buyers are drawn to: stone houses, island villas, period apartments. The standard does not care that the building is charming. It reads the rating.

This is why the certificate and the standard are one story. The EPC measures where the building sits, MEPS sets where it has to get to, and the gap between them is the scope of work. An owner who knows both can plan an upgrade that clears the standard and, where eligible, draws on state support to pay for most of it.

Before the Standard Forces the Work

Carrot and Stick, Same Decision

The regulation is the stick. The grant window is the carrot, and it is open at the same time. Greece is funding residential upgrades through 2032, with the next round offering up to 80 percent of eligible costs for primary residences, set out in our guide to Greek property energy upgrade grants. Doing the work now, with support, against a standard you will have to meet anyway, is a different financial decision from doing it later under compulsion at full price. For owners who bought recently, the upgrade also protects the asset value documented in a property condition assessment.

The honest framing is not fear. The standards are real, the deadlines are public, and the regulation pushes in the direction an owner would want to go anyway: a warmer, cheaper-to-run, more valuable home. The only variable the owner controls is timing.

Upgrading an Older Greek Home?

Before the standards bite, we confirm the building’s current rating, the scope to meet the coming MEPS, the grant-eligible portion, and a privately financed route where the grant does not apply. Independent, English-language, contractor invoicing you directly. Start at kgnordic.com/contact or see the energy upgrade service.

Minimum standards turn an optional upgrade into a scheduled one. The question stops being whether to upgrade an older Greek home and becomes whether to do it now, with support, or later, under a deadline. That is the whole decision.

Frequently Asked Questions

Q - What are MEPS in Greece?

MEPS are minimum energy performance standards for buildings, introduced by the EU Energy Performance of Buildings Directive and being transposed into Greek law through a revision of the KENAK building energy code. They set a minimum energy rating a building must reach, often enforced at sale or lease.

Q - When do Greek minimum energy standards take effect?

The EU deadline to transpose the directive was 29 May 2026. Greece is finalising this through its KENAK building energy code, so the exact national thresholds and trigger dates are still being set and should be verified against the Greek law as it lands. At EU level, the worst-performing 16 percent of non-residential buildings must be renovated by 2030 and 26 percent by 2033, while homes fall under a national renovation trajectory.

Q - Does MEPS affect older and holiday homes?

The standards apply to existing buildings and press hardest on the worst-performing, older stock. Holiday homes are not exempt from the standards themselves, though they are not eligible for the primary-residence grant and are upgraded on a privately financed basis.

Q - Can fossil-fuel boilers still be subsidized in Greece?

No. Subsidies for standalone fossil-fuel boilers have been banned since the start of 2025, with a phase-out toward 2040 under the EU directive. Support is directed to efficient systems such as heat pumps.

Q - How do I find out if my Greek home meets the standard?

Start with the building’s energy performance certificate, which records its current rating, and an assessment of the gap to the coming standard. We provide an independent read on both in the Eligibility Check.
