What the Heating Law Reform Means - Stricter 2028 heating rules push homes toward greener fuels by 2040

New rules for heating systems will come into force from 2028, aiming to cut emissions in homes across the country. The changes mean gas and oil boilers must gradually use more climate-friendly fuels. Property owners will still be allowed to install traditional systems, but with stricter requirements over time.

Starting in January 2029, any newly installed gas or oil heating system will need to run on an increasing share of green fuels. This 'bio escalator' will push the proportion of climate-friendly energy up until 2040. Fuels like biomethane, synthetic methane, and hydrogen will replace some of the fossil-based supply.

Energy suppliers must begin offering these greener alternatives by 2028. However, switching will come at a cost. Households using biomethane can expect an extra €16 per month, while bioheating oil adds around €23 for average usage.

The reform also keeps subsidies for heat pumps, though the exact funding levels and who qualifies may shift. From 2030, all new buildings must meet tougher climate standards, with heating systems relying fully on renewables or low-CO₂ sources. Existing systems can use biomethane without changes, but hydrogen may need pipeline upgrades for higher concentrations.

The changes give homeowners options but push them toward cleaner climate change over time. Traditional boilers will still be available, though running them will get more expensive. By 2040, most systems will need to use a large share of green fuels to comply with the law.
