How Often Should My Chimmey Be Swept?

The frequency of sweeping depends on what you are burning, and whether you notice any changes.

For instance, if you start seeing soot or tar deposits in the fire grate, or your appliance starts smoking back/has difficulty in getting a fire going, then it’s time to call in the experts.

If, however, all seems well, then you should be getting your appliance swept as follows:

Smokeless fuel:

At least once a year

Wood:

Quarterly when in use

Bituminous (house) coal:

Quarterly when in use

Oil:

Once a year

Gas:

Once a year
