What the Global Ban on Gas Heating in New Real Estate Will Change

Prime Minister Sébastien Lecornu announced on Friday the ban on gas heating in all new constructions from the end of the year: individual homes, collective housing and tertiary buildings. This measure aims to reduce dependence on fossil fuels in a sector that represents a significant share of CO2 emissions. Two million social housing units must abandon gas by 2050, with a doubling of electrification aid to 10 billion euros per year.

Gas Ban Extended to All New Buildings

A Measure That Takes Effect Quickly

Sébastien Lecornu made this announcement from Matignon on Friday. From the end of the year, the installation of gas boilers will be prohibited in all new constructions. The ban, which already concerned individual houses, now extends to collective housing, offices, shops and warehouses.

On the ground, this generalization marks a turning point. Developers and builders will have to adapt all their ongoing projects.

Heating Figures in France Today

According to Insee, 36% of primary residences are heated with electricity. Natural gas equips 35% of homes, fuel oil 8.5%.

In the social housing stock, the situation is different. 55% of social housing still runs on gas. The government's objective: zero social housing with gas by 2050, meaning two million units to convert.

Why This Ban Now

Reducing Dependence on Fossil Fuels

The Prime Minister said it clearly: "As long as we depend on oil and gas, we will continue to pay the price of other people's wars". The phrase sums up the issue.

Gas and oil heating remains the main source of CO2 emissions in the residential sector. By cutting gas in new buildings, the government seeks to reduce these emissions and secure national energy supply.

It's a question of sovereignty as much as climate.

A Tense Geopolitical Context

Gas prices fluctuate according to international tensions. Dependence on imports makes households and businesses vulnerable to these variations. The gas ban in new buildings is part of this search for energy autonomy.

Preferred Replacement Solutions

Heat Pump as Main Alternative

The government is betting on the electrification of uses. According to it, 80% of individual houses are compatible with a heat pump.

In practice, everything depends on the building's insulation and the power of the electrical meter. A properly sized heat pump in a recent, properly insulated house can divide the heating bill by three. But in a poorly insulated building with an old radiator network, efficiency drops and electricity consumption rises.

Before considering a heat pump, check two things: your home's thermal insulation and your electrical installation's capacity. An undersized subscription can trigger outages in the middle of winter.

Collective Housing Challenges

Installing a heat pump in a condominium is another matter entirely. The technical constraints are heavier: space for outdoor units, condominium agreement, adaptation of the heat distribution network.

Several specialized associations, including Cler, have called for a more comprehensive approach. They recommend coupling heating replacement with thermal insulation work. Without this, you change the production method but don't really reduce the bill.

The Government's Financing Plan

Doubling of Electrification Aid

The budget allocated to aid increases from 5.5 to 10 billion euros per year. This aid targets individuals and social landlords who abandon gas for electric or renewable solutions.

The government maintains this budget despite budgetary constraints and a public deficit at 5% of GDP.

Financing Through Expenditure Reorientation

Sébastien Lecornu specified that this is not additional public money. The financing comes from a reduction in fossil energy expenditures and a reorientation of existing funds.

The government also plans to mobilize energy savings certificates and seek more private financing. On paper, it holds up. On the ground, we'll have to see if the announced amounts actually reach households.

Concrete Impacts for Different Stakeholders

For Developers and Builders

Ongoing construction projects will have to revise their heating plans. In some cases, it's a simple adjustment. In others, particularly for collective buildings, it involves rethinking the entire installation.

There will be a short-term additional cost. The question is who bears it: the developer, the buyer, or both.

Teams will also need to train on new installations. Installing a collective heat pump is not the same as installing a gas boiler.

For Social Landlords

Two million housing units to convert by 2050 represents a colossal project. Social landlords will have to plan this work over several decades and prioritize the most energy-intensive buildings.

They will have priority access to public aid, but will also have to manage the impact on tenants' charges. A poorly done conversion can increase electricity bills without reducing overall consumption.

For Individuals Buying New Properties

If you buy a new home, you will no longer have a choice of heating method. It will be electric, wood or urban heating network. Gas disappears.

Concretely, this means increased dependence on the electrical grid. If your home is well insulated and the heat pump is properly sized, the bill will remain reasonable. If the insulation is average, you risk seeing your electricity consumption increase in winter.

Thermal insulation therefore becomes a determining criterion when purchasing.

Outstanding Technical Questions

Electrical Grid Capacity

If millions of homes switch to electric heating, winter demand will increase. The electrical grid will have to handle this increase, especially during peak hours.

In some areas, the grid will need to be reinforced. This takes time and money. The government also encourages the development of renewable energies to support this ramp-up.

The Case of Existing Buildings

The ban only concerns new buildings. If you have a gas boiler in an old home, you are not required to replace it.

However, the reduced VAT rate of 5.5% on very high performance gas boilers has been eliminated. The rate rises to 20%. It's a signal: the government wants to gradually discourage gas, even in existing buildings.

Aid now focuses on heat pumps and wood boilers.

What Concretely Changes on the Ground

In the Next Six Months

Until the end of the year, it is still possible to install gas boilers in new constructions. We can expect a final rush on projects being finalized.

Unified Technical Documents will be adapted to integrate this ban. Installers will need to train massively on alternatives, particularly heat pumps.

Still Unclear Sectors

Some gray areas remain. How to treat mixed buildings, which combine housing and shops? What about extensions to existing buildings? And for projects already launched, what compliance deadlines?

The articulation with urban heating networks also remains to be clarified. These networks, powered by geothermal or biomass, are encouraged elsewhere. Are they concerned by the gas ban? Normally no, but the texts will need to clarify this.

Sector Reactions

Environmental and Energy Associations

Cler and other associations call for a more complete approach. Changing the heating method without working on insulation means missing the problem. They ask for reinforced support for households to avoid unpleasant surprises.

The request is legitimate. On the ground, I've seen too many heat pumps installed in thermal sieves. Result: the electricity bill explodes and comfort remains mediocre.

Building Professionals

Craftsmen and installers will have to adapt quickly. Many are used to installing gas boilers. Massively switching to heat pumps requires training and a change of tools.

There is also uncertainty about supply times. If demand explodes and supply doesn't follow, prices will rise and delays will lengthen. This has already happened with other equipment.

Perspectives and Alternatives to Watch

Other Compatible Heating Methods

Gas disappears from new buildings, but other options remain authorized. Wood heating, under certain conditions, is still possible. A stove or wood boiler with a Flamme Verte 7-star label remains eligible.

Urban heating networks, powered by geothermal or biomass, are encouraged. Solar thermal can also complement a main installation.

The idea is to move away from fossil fuels, not to bet everything on electricity.

Likely Evolution of Regulations

The ban only affects new buildings for now. But extension to existing buildings could come in the medium term. The signal has already been sent with the end of reduced VAT on high-performance gas boilers.

The RE2020 environmental regulation will also gradually tighten. Insulation requirements will increase, which will make buildings more compatible with heat pumps.

At the European level, harmonization is underway. Other European countries have already taken similar measures.
