All UK households with chimneys urged to do 1 thing now or risk dangerous consequences

All UK households with chimneys are urged to make an important check now before lighting their fireplaces this winter. As the colder weather begins to slowly settle in, many households will soon be relying on their chimneys and wood burners for warmth. But experts say failing to check one crucial thing could lead to major safety risks, including house fires and carbon monoxide poisoning.

Chimneys that haven't been properly maintained since last winter may have suffered damage, become blocked, or built up dangerous debris. Even small cracks can reduce efficiency or allow harmful gases to escape into the home. There are also concerns about creosote, which is a highly flammable substance that builds up when burning wood, and the possibility of animals nesting inside flues during the summer.

Experts at The Chimney Experts say it's vital to carry out a full inspection before using any fireplace or stove this winter season.

And they're urging all households with chimneys to test their carbon monoxide detectors now.

Roger, the owner of The Chimney Experts in London, said: "I can't stress enough the importance of preparing your chimney for the winter season. A well-maintained chimney not only ensures efficiency but also safeguards your home from potential hazards."

The company recommends booking a professional chimney sweep, checking the structure for cracks or damage, and making sure the chimney cap is in good condition.

Homeowners should also clear the firebox of old ash, test the damper, and use only seasoned firewood that has been dried for at least six months.

Testing carbon monoxide alarms is especially important. The detectors should be placed near any fireplace or wood burner, have working batteries, and be checked using the test button.

Roger said: "Working smoke and carbon monoxide detectors can save lives by providing early warnings of potential dangers. If you don't have them installed, now is the time."

The chimney liner should also be examined for cracks, gaps, or signs of wear. If damaged, it must be repaired or replaced by a professional to prevent chimney fires and ensure safe operation.

Ventilation is another key area, as poor airflow can lead to smoke build-up and carbon monoxide risks.

Lighting a small piece of newspaper in the fireplace can help test whether smoke rises smoothly through the chimney.

Households are also being reminded never to leave fires unattended, use a fireplace screen, and keep flammable objects away from the hearth.
