The Department for Environment, Food and Rural Affairs (DEFRA) is considering stringent new regulations for log burner owners across the UK, following a consultation launched earlier this year. Proposals include tougher emissions limits, compulsory labelling on new appliances and fuels, and increased penalties.
DEFRA stated that the goal is to address "one of the largest environmental risks to human health." The department explained that fine particulate matter (PM2.5) consists of tiny particles capable of penetrating the lungs and entering the bloodstream.
It said it is: "Linked to conditions such as heart disease, asthma, and premature death. Vulnerable groups, including children, older people, and those with existing health conditions, are most affected."
Domestic burning and PM2.5 emissions
DEFRA confirmed that the domestic burning of solid fuels, including wood and manufactured solid fuels, is a significant contributor to PM2.5 emissions. In 2023, it accounted for roughly 20% of the UK's total PM2.5 emissions, comparable to that of road transport.
During the consultation, officials added: "While air quality has improved overall, emissions from domestic burning have risen in recent years as stove use has grown in popularity. Tackling this issue is essential to protect health and reduce the estimated £20 billion annual cost of air pollution to society."
Three key parts of the plan
The proposed measures include stricter emission limits for new stoves, introducing tougher smoke emission standards for new appliances placed on the market. Mandatory labelling for stoves and fuels would provide clear information on emissions, permitted fuels, and health impacts to help consumers make informed choices. Increased enforcement penalties would raise penalties for suppliers who breach fuel standards to ensure compliance.
When approached regarding the release of the consultation results, which are now due, a DEFRA spokesperson responded: "We are currently carefully considering all responses to the consultation and will publish a formal government response in due course."
UK-wide consultation and research findings
The consultation spans the whole of the UK and has been carried out by DEFRA in partnership with the Scottish Government, Welsh Government and DAERA. Any subsequent measures taken in response to the consultation's findings will be developed in conjunction with the Devolved Governments.
Ground-breaking research from the University of Birmingham has revealed that burning wood at home generates greater levels of pollution than road traffic. The study found that a quarter of harmful particles in the air, known as PM2.5s, are produced by domestic fires, while traffic accounts for 22%.
Wood-burning stoves have surged in popularity across the UK, with an estimated 1.9m homes now owning one, according to the Stove Industry Alliance. The study's lead investigator, Prof Zongbo Shi, admitted he was taken aback by his own findings, saying it "demonstrates the huge impact" burning wood at home has. Prof Shi added he hoped it would make people consider "if there is a real need to use their stoves."
