Do I Need a Chimney Liner for an Open Fire

A chimney liner is obligatory if you are installing a woodburning stove, gas fire or open fire in a new build property to comply with Document J of current Building Regulations. A chimney liner may be necessary in an older property if the flue inside your chimney is no longer safe to use.

What type of chimney do I need for an open fire?

Open wood burning and coal fires require a class 1 flue liner with a minimum diameter of 200mm. Open fires with larger fireplace openings (usually freestanding grates) will need larger flue sizes calculated alongside the height of the chimney and required ventilation.

Is my chimney safe for an open fire?

The best way to ensure your fireplace is safe to use, whether it be wood burning or gas fired, is to have a professional inspection annually. The lack of proper maintenance of your fireplace can cause many hazardous conditions including fire, carbon monoxide poisoning and toxic fumes.
