The wood heating market: beware of frauds on logs and pellets

With a growing number of French households choosing wood heating as an economical and more ecological solution, the success of this renewable energy is unfortunately accompanied by numerous frauds. Since the energy crisis of 2022, the demand for wood logs and pellets has exploded, creating an opportunity for some unscrupulous sellers. These scams, whether they involve misleading information about the quality of fuels or false advertisements on the Internet, endanger not only the consumers’ wallets but also the trust in this sustainable heating method.

In response to this situation, the General Directorate for Competition, Consumer Affairs and Fraud Control (DGCCRF) has increased inspections, revealing a market still too often marred by irregularities ranging from non-compliance with regulations to abusive and misleading commercial practices. This rise in fraud calls for vigilance regarding the quality of purchased products and the selling conditions, so as not to compromise the performance of wood heating installations and their environmental impact.

Controls and alarming findings on wood heating fraud

A thorough investigation conducted between 2023 and early 2024 by the DGCCRF meticulously examined 185 companies specializing in the sale of wood logs and pellets intended for domestic heating. Wood heating attracts more than 7 million households in France, drawn by its relatively stable cost compared to gas or electricity and its renewable energy label. However, this strong demand, especially fueled by rising energy prices since 2022, exerts pressure on the supply that fuels fraud in this market.

The outcome of this investigation is clear: 45 warnings and 29 injunctions were issued to the sellers inspected for serious violations.

• Failure to display or misleading information: many companies do not clearly present prices and associated fees – particularly delivery – which undermines transparency for buyers. The DGCCRF reports that 37% of operators do not comply with these display obligations.
• Deception regarding product quality: false claims about the length of logs, moisture content not complying with standards or misrepresentation of the types of wood purchased.
• Abusive clauses in contracts: in 70% of the companies inspected, illegal clauses were included in the general sales conditions (GSC), relating to the absence or delay of reimbursement for delivery charges and non-compliant withdrawal periods.
• Non-compliance with commercial regulations: 53% of the companies did not provide their customers with the possibility to register on a telephone marketing opposition register (Bloctel), and 62% did not mention any consumer mediator in their GSC.

This picture underscores the urgent need for increased consumer vigilance and shows that product certification remains essential to ensure the quality of pellets and wood logs used in biomass-connected wood heating installations.

Summary table of the main frauds observed

Type of fraud	Percentage of concerned companies	Consequences for the consumer
Non-compliance with price display	37%	Confusion about the total cost, hidden fees
Misleading information about fuel quality (length, moisture)	Variable but significant	Reduced heating performance, overconsumption
Illegal clauses in GSC	70%	Limited retraction, delayed reimbursements
Absence of opposition to telephone marketing (Bloctel)	53%	Aggressive marketing, intrusion into personal life
Absence of consumer mediator	62%	No simple solution in case of disputes

Online fraud: essential vigilance when purchasing pellets and logs

The digitalization of wood heating sales has favored an explosion of online fraud. Platforms for classified ads like Le Bon Coin, Marketplace spaces on Facebook, or instant messaging networks such as WhatsApp or Telegram have become playgrounds for scammers. They post offers at rock-bottom prices, claim to be certified wood professionals, often impersonate the identity of real sellers, and then vanish after payment without delivery.

This worrying trend forces consumers to be extra cautious. Several practical tips can help limit exposure to scams:

• Check product certification: prioritize pellets and wood logs that are labeled, physically accompanied by recognized official certifications regarding quality and moisture content.
• Prefer certified sales and recognized distributors: rely on registered professionals who strictly adhere to legal and tax norms.
• Avoid transactions only via messaging or social networks: prefer platforms with guarantees, recourse options, and visibility of sellers.
• Request a detailed and signed quote: verify every element, from price to the length of logs, including delivery methods and additional fees.
• Research the reputation and customer reviews of the seller, especially on forums or websites specializing in wood heating.

In light of these risks, it is useful to refer to authentic testimonies about scams in the wood energy sector, such as those compiled on the site Le Marché du Bois or on Sud Ouest.

Checklist of points to verify before any online purchase

1. Ensure that the seller is registered with the trade registry and presents their general sales conditions
2. Confirm the mention of a consumer mediator in the contractual documents
3. Check the clarity and visibility of price display, including delivery charges
4. Request concrete proof of quality (certification, analysis of moisture content)
5. Consider using secure and traceable payment methods

These precautions significantly reduce the risks of falling victim to fraud in this dynamic yet fragile market.

Quality of fuels and its impact on the performance of wood heating

The quality of fuels – wood logs or pellets – is a determining factor in the energy efficiency and durability of a wood heating system. Non-compliant biomass, particularly with too high moisture content, leads to incomplete combustion, more pollution, decreased calorific power, and premature wear of devices.

Product certification plays a key role in guaranteeing consumers a fuel that meets environmental standards and requirements. In 2025, PEFC or DINplus certified pellets are the assurance of controlled raw materials, which ensures stable combustion, reduced pollutant emissions, and better heat yield.

From a technical perspective, a moisture content below 20% is essential to guarantee good combustion. Logs sold with a moisture content higher than that generate more smoke and promote the formation of harmful deposits in the ducts, increasing the risk of clogging and fire.

• Type of wood: Hardwoods such as oak or beech are preferable for their high calorific power compared to softwoods.
• Length of logs: A good adaptation to the size of the hearth improves the efficiency of combustion.
• Storage: Keeping wood in a dry and ventilated place avoids degradation and re-absorption of moisture.
• Use of certified pellets: Ensures compliance with quality criteria and compatibility with modern pellet stoves.

Comparative table of quality criteria for wood fuels

Criterion	Wood logs	Pellets
Recommended moisture content	< 20%	< 10%
Recommended type	Hardwoods	Mixed hardwoods/softwoods (certified)
Physical form	Calibrated logs	Compressed pellets
Standards and certifications	Eco-labels and wood energy certifications	PEFC, DINplus, ENplus
Impact on combustion	Good yield if dry	Homogeneous, reduced pollution

Economic and environmental consequences of frauds in the wood heating sector

The loss of consumer trust due to fraud heavily impacts a sector that is key in the energy transition. Wood heating appears as both an economic and ecological alternative, contributing to the goal of reducing fossil energy consumption. However, the emergence of non-compliant products and unclear commercial practices undermines these advantages.

From an economic standpoint, these frauds lead to:

• Hidden extra costs: customers forced to repurchase fuel due to inefficient combustion or a real volume lower than that announced.
• Prejudice for serious distributors: devaluation of their offer due to overall distrust.
• Loss of possible subsidies and aids, as some government schemes require the certification of fuels and equipment.

From an environmental perspective, poor product quality promotes:

• Increased local pollution: smoke with a high level of fine particles and toxic compounds.
• Negative impact on the overall carbon balance: incomplete combustion releasing more CO2 and other pollutants.
• Waste of biomass: poorly utilized natural resources, increasing pressure on forests.

This reality also raises questions about the application of an ecological tax, considered to better regulate this market and encourage the consumption of certified products. To learn more about these issues, it is recommended to consult detailed analyses on Prime Coup de Pouce Chauffage.

Upcoming regulations and advice for sustainable wood heating in 2025 and beyond

In response to the constant rise in fraud and the need for safe and environmentally friendly wood heating, several regulatory measures are under discussion or being implemented. In particular, a gradual ban on the most polluting installations is on the horizon, with an end to their marketing planned before 2027. This legislative context encourages the use of efficient devices and certified fuels.

Some essential points to keep in mind:

• Evolution of regulations: The establishment of an ecological tax on wood heating to encourage the use of quality fuels and limit negative environmental impacts.
• Obligation of fuel certification: starting from 2025, legislation will provide for stricter control over the compliance of wood logs and pellets sold to individuals.
