2026 biomass boiler subsidies: Luxembourg, Belgium, France, Switzerland, Canada

A note of caution

The amounts, ceilings and conditions below reflect the state of the schemes as of 26 April 2026. Official rates change every year, and some measures may be suspended, modified or replaced without notice. The official pages linked in each section remain the only authoritative references. Our team systematically verifies eligibility at the time of the quote.

Luxembourg — Klimabonus 2026

The Klimabonus is the flagship scheme of the Luxembourg Ministry of the Environment, Climate and Biodiversity for energy-efficient renovation. The 2026 regime has dropped pro-rata calculations in favour of fixed lump sums based on the type of work.

For a wood-pellet boiler in a single-family home, the official lump sums are: €8,000 with replacement of an existing fossil (heating oil, gas) or electric boiler; €4,000 without replacement. For multi-unit buildings: €6,000 per dwelling, capped at €40,000 for the entire building, conditional on replacing a fossil system.

• Particulate emissions ≤ 8 mg/m³
• Production efficiency ≥ 90 %
• Automatic feed and ignition mandatory
• Connection to a central heating circuit
• Existing dwellings only (no new builds)
• Submission deadline: 4 years from 31 December of the invoice year

Wallonia — Prime habitation: scheme closed

The temporary Primes Habitation scheme, in force from 14 February 2025 to 30 September 2026, closed on 30 September 2026 (logement.wallonie.be).

By 3 October 2026 no new scheme had been published: check the official website before any project. Our prices are shown without any grant deducted.

• Temporary scheme: 14/02/2025 – 30/09/2026 (closed)

Brussels — Renolution currently suspended

As of 26 April 2026, the Renolution subsidies have been SUSPENDED since early 2025 due to the lack of an operational Brussels government. No new subsidy application can be submitted for invoices from 2025 or 2026. Only invoices dated 2024 could be processed, and the submission period is now closed. The official renolution.brussels site confirms that no government decision has been made on new forms of financial support for renovation.

Alternatives still available in Brussels: the reduced 6 % VAT for renovation work (dwelling > 10 years), the ECORENO loan (zero or reduced interest rate) via Crédit Logement Bruxelles, and certain municipal subsidies (« primes de type B ») that vary by commune. For guidance, contact Homegrade on 1810 or environnement.brussels.

• Status: subsidies suspended — no 2025/2026 applications accepted
• 6 % VAT renovation still applicable
• ECORENO loan via Crédit Logement Bruxelles

Flanders — Mijn VerbouwPremie

Mijn VerbouwPremie does not cover biomass boilers: for renewable energy production, the official list of eligible works only includes heat pumps and heat pump water heaters (vlaanderen.be, consulted on 3 October 2026).

The 'up to €3,500' sometimes quoted for biomass therefore does not apply to a pellet boiler.

• Biomass boiler: not included in Mijn VerbouwPremie

France — MaPrimeRénov' (major change in 2026)

Structural regulatory change since 1 January 2026: the installation of a biomass boiler (wood or pellets) is EXCLUDED from the « mono-geste » pathway of MaPrimeRénov'. In practice, a pellet boiler can no longer be financed on its own through MaPrimeRénov'.

Biomass remains eligible ONLY in the context of a large-scale renovation — i.e. a global project that lifts the dwelling by at least 2 energy label classes. The work caps are €30,000 net of VAT for a 2-class jump and €40,000 net of VAT for 3 classes or more. The portal reopened on 23 February 2026 after the budget law was passed.

Possible combinations: CEE « Coup de Pouce Chauffage » bonus, éco-PTZ up to €50,000, reduced 5.5 % VAT for energy improvement work in a primary residence ≥ 2 years.

• Mono-geste: biomass boiler EXCLUDED since 1 January 2026
• Large-scale renovation: caps €30,000 net (2 classes) or €40,000 net (3+ classes)
• Combinations: CEE Coup de Pouce, éco-PTZ, 5.5 % VAT

Switzerland — Buildings Programme 2026

The Buildings Programme is a federal scheme co-financed by the cantons. For an automatic wood boiler (pellets, chips) up to 70 kW replacing a fossil installation (heating oil, gas, fixed electric heating), the base lump sums are: CHF 8,500 for installations ≤ 20 kW (typically a single-family home), CHF 4,500 + CHF 200 per kW above 20 kW.

Additional myclimate bonus: about 18 cents per kWh of fossil energy avoided, i.e. approximately CHF 360 per kW of correctly sized installed power. Strict conditions: the boiler must cover 100 % of the heating + DHW need from renewables, and replace heating oil, gas or fixed electric heating (not another wood system).

Rates vary by canton. For the canton of Vaud, the M-02 (logs) and M-03 (automatic pellets/chips ≤ 70 kW) procedures are documented on vd.ch. For other cantons, start at leprogrammebatiments.ch and select your canton.

• Automatic wood boiler ≤ 20 kW: CHF 8,500 lump sum
• Automatic wood boiler > 20 kW: CHF 4,500 + CHF 200/kW
• Myclimate bonus: ~CHF 360/kW (https://www.myclimate.org)
• Must replace heating oil / gas / fixed electric heating

• Vaud (example): https://www.vd.ch (M-02 and M-03 services)

Canada — federal and provincial programmes

The federal Canada Greener Homes Grant has been CLOSED since February 2024. Its successor, the Canada Greener Homes Affordability Program (CGHAP), targets low- and middle-income households via a direct-install model and is being rolled out province by province in 2026. As of 26 April 2026, biomass / pellet boilers are NOT among federal priority technologies (focus on heat pumps, insulation, windows, solar panels).

The real lever for biomass in Canada lies at the provincial level. In Quebec, the Chauffez Vert programme (Transition énergétique Québec) covers replacing a heating oil system with certified biomass. In British Columbia, CleanBC programmes offer comparable incentives. In Ontario, support is more limited and runs mainly through Save on Energy.

Always verify with Natural Resources Canada (1-833-674-8282) or the provincial programme for your jurisdiction before signing the quote.

• Federal Greener Homes Grant: CLOSED (since February 2024)
• CGHAP: low/middle incomes, provincial rollout in progress
• Biomass: not a federal priority in 2026, check provincial

Building a flawless application

A rejected subsidy application is almost always one where a document is missing or a deadline has been missed. Here are the items we provide systematically on every Tatano project:

• Detailed Tatano quote (power, model, energy class, EN 303-5 certificate)
• Grant application submitted BEFORE work begins when the programme requires it (e.g. the Swiss Buildings Programme)
• Prior energy audit or energy advice when the programme requires it
• Final invoice with VAT details and certificate from approved installer
• Disposal / destruction certificate for the old appliance
• Each programme's own submission deadline respected (checked on the official page)

Our support

Tatano Luxembourg is neither a subsidy brokerage nor your tax adviser — we do not replace either of those professionals. What we do provide systematically is the manufacturer certificates, declarations of conformity, the technical breakdown of the quote and a project summary — all of which the authorities require. For complex cases (heavy renovation, listed building, co-ownership, cross-border project), we work regularly with partner energy consultancies in Luxembourg, Belgium, France and Switzerland.
