Safety Information

Chimney Sweeping


The two main reasons for having your chimney swept are safety and efficiency. Clean chimneys do not catch fire.

The flue/chimney is designed to allow a smooth, easy way for the exhaust gases to leave your fire. The exhaust gases may be made up of soot particles, creosote and carbon monoxide which are harmful and dangerous.

So the swift removal of the flue gases is essential to the safe operation of any type of fire or appliance. In addition, soot and creosote are flammable and therefore a build up of either within the flue or chimney dramatically increases the chance of having a chimney fire.


Guild qualified chimney sweeps employ a range of different methods for cleaning a variety of chimneys and flues. The traditional method of rods and brushes are used on open fires and unlined chimneys, whilst a more modern flexible continuous rod and brush method is generally used on flexible liners.

In all instances, the cleaning is carried out in conjunction with a powerful industrial vacuum. This creates negative pressure that keeps the soot contained throughout the sweeping process and results in a clean and tidy sweep.

How to Prevent Chimney Fires

Carbon Monoxide - The silent Killer

Invisible, odourless and tasteless - Carbon Monoxide (CO) is a deadly gas. Exposure to even relatively low levels of this highly poisonous gas can cuase brain damage or death. You cannot see, smell or taste it. If left undetected it is deadly.

CO2 warning

Symptoms of Carbon Monoxide exposure can include: drowsiness, weakness, headaches, nausea and chest pains. If anyone in your home displays any of these symptoms consult a Doctor and immediately shut down your fire. Do not start using it again until your appliance has been checked by a qualified heating engineer.

Carbon Monoxide can be produced where an appliance has been incorrectly installed or a flue or chimney has become blocked. Tell tale signs to look out for include sooting on the appliance, a yellow or orangy lazy flame and excess condensation in the room where the appliance is installed.

Simple steps to Carbon Monoxide safety:

Chimney Sweeping Frequency

Fuel type Sweep Frequency
Smokeless coals At least once a year
Bituminous coal Twice a year
Wood Up to 4 times a year
Oil Once a year
Gas Once a year
