Guild sweeps undertake an extensive training and assessment process. Training is based around the most comprehensive training manual of its kind in the UK.
Guild membership requires members to be insured for chimney sweeping and equipped to deal with all standard job situations.
As the Guild is owned equally by all its members it can act like a co-operative, sharing information and solving customer problems. In the unlikely event that your Guild sweep is unable to help you, they should be able to recommend someone who can.
