We pay € 30 in the South East .But the price does vary from €30 - €45
The method also varies , from type of brushes to suction and also some clean from rooftop and others from fireplace .
Some block fireplace and clean from rooftop - others block fireplace and use brushes through small hole .
This is only my experience of using chimney cleaners .
I believe its recomended that chimney is cleaned twice yearly .
