We are making a change for a better world

Stoves and fireplaces with the clearSkies certification produce significantly lower levels of emissions compared to open fires and older stoves. Independent tests have shown a clearSkies stove produces up to 90% less emissions than an open fire and 80% less emissions than the average 10-year-old stove.

If a stove or fireplace is clearSkies certified you can be assured that it meets ALL the criteria needed to be legally installed and meets the latest environmental standards. You don’t need to look for any other certification.

clearSkies demonstrates the industry’s commitment to improving air quality by developing low carbon heating solutions, and by choosing a clearSkies certified product you too are doing your bit to lower emissions, improve air quality and make a change for a better world.
