Sweeping: How Often?

Every chimney which is in use needs to be swept. It’s the only way to ensure there is a safe passageway for dangerous gases to leave the house, and to stop a potential chimney fire

The frequency of sweeping depends on what appliance you have. But as a guide, it should be 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
