A new investigation reveals how the wood burning stove industry has threatened legal action against councils attempting to warn residents about the serious health risks posed by domestic wood burning.
An investigation published by The British Medical Journal has exposed a concerning pattern of legal intimidation used by the stove industry to suppress public health campaigns warning about the dangers of wood burning stoves. The research, which analysed Freedom of Information requests from councils across England, reveals that the industry has deployed litigation threats and aggressive lobbying tactics to silence authorities attempting to inform residents about air pollution risks.
The investigation found that almost one-third of the 50 councils in England with the highest concentration of wood burning stoves have been threatened with legal action or subjected to lobbying pressure by the Stove Industry Association (SIA). This includes eight London boroughs—Croydon, Islington, Lewisham, Southwark, and Wandsworth—which were threatened with legal proceedings in late 2023 over a public health awareness campaign. Brighton and Hove City Council also faced pressure following its campaigns about wood burning, particularly after sensor data revealed dramatic spikes in harmful particle pollution at 10pm, when wood burners are typically ignited.
The scale of the health threat is significant. Wood burning stoves are present in approximately one in ten homes across England, making domestic burning a major source of fine particulate matter (PM2.5)—the air pollutant most harmful to human health. Research cited by England’s Chief Medical Officer, Professor Chris Whitty, demonstrates that even the newest environmentally designed stoves emit considerably more pollution than gas boilers or electric heating systems. Prolonged exposure to PM2.5 is linked with cardiovascular disease, cancer, asthma, and stroke, with outdoor air pollution caused by domestic burning associated with approximately 2,490 deaths annually across the UK.
What stands out as particularly troubling is the nature of the pressure councils have faced. Three councils—Dudley in the West Midlands, Elmbridge in Surrey, and Rushmoor in Hampshire—received materials from the SIA claiming that wood burning provides “health and wellbeing benefits,” directly contradicting evidence from the Royal College of Paediatrics, the Royal College of Physicians, and the Chief Medical Officer. The industry has also distributed leaflets claiming there is “no scientific evidence” for adverse health effects from wood burning, a position at odds with growing peer-reviewed research linking wood smoke to serious disease.
The World Health Organisation classifies PM2.5 pollution, including that from wood burning, as a known carcinogen. Dr Laura Horsfall of the Institute of Health Informatics emphasised the need for clearer public messaging, noting that “wood burning is often marketed as natural, cosy, or environmentally friendly,” despite even Ecodesign stoves not being pollution-free. The Advertising Standards Authority has previously ruled against the SIA, finding that newer Ecodesign stoves did not significantly reduce greenhouse gas and air pollutant emissions compared to older wood stoves and open fires.
Jonathan Blades, head of policy at the charity Asthma + Lung, expressed serious concern about these tactics, stating that the industry’s approach “clearly tries to undermine public awareness of those risks, and that means people aren’t able to make informed decisions for their health.”
The timing of this investigation is significant, as the UK Government is currently consulting on measures to reduce smoke emissions from solid fuel burning. These proposed measures include stricter limits on newly purchased stoves and mandatory health warning labels on fuels. A Department for Environment, Food and Rural Affairs spokesperson stated: “Dirty air robs people of their health and costs our NHS millions each year. We’ve set new ambitious targets to cut air pollution by a third by 2030.”
The SIA responded to the investigation, telling The BMJ that its correspondence with local authorities “has been aimed at trying to provide a balanced and educational position” and that the organisation has not “intentionally set out to undermine public awareness about the health effects of domestic wood burning.” However, the documented evidence of legal threats and contradictory health claims suggests a pattern of aggressive industry tactics designed to prevent public health messaging.
The investigation highlights a broader concern about how industries respond when evidence emerges showing their products pose health risks. Rather than supporting councils in communicating these risks to vulnerable residents, the stove industry has deployed legal pressure designed to deter public health authorities from reaching residents with crucial information. This is particularly concerning given that air pollution disproportionately harms children, older people, those with existing health conditions, and residents in lower-income areas.

Key Takeaways
- Almost one-third of England’s 50 councils with the highest concentration of wood burning stoves have been threatened with legal action or lobbied by the Stove Industry Association
- Even the newest “eco-design” stoves emit considerably more pollution than gas boilers or electric heating, with PM2.5 pollution linked to cardiovascular disease, cancer, asthma, and stroke
- The UK Government is consulting on stricter limits for newly purchased stoves and mandatory health warning labels, whilst councils face legal intimidation for warning residents about health risks
What This Means for Kent Residents
Kent residents should be aware that wood burning stoves, whilst appearing as a traditional or environmentally friendly heating option, contribute significantly to local air pollution and pose genuine health risks—particularly for children and those with respiratory or cardiovascular conditions. If you’re considering installing a wood burning stove or currently use one, speak to your GP or healthcare provider about the potential health implications for you and your household. For Kent residents with concerns about air quality or health impacts related to air pollution, contact your local GP surgery or NHS 111 for guidance. The Kent and Medway NHS Trust provides respiratory and cardiovascular services, and residents concerned about air quality impacts on their health should discuss this with their healthcare team. Keep an eye on government consultations regarding clean air measures—your feedback during these periods can influence local air quality policies that affect your community.
