About Us
The National Association of Chimney Sweeps (NACS) formed in 1982 as a professional Trade Association, promoting high standards for the sweeping, inspection and maintenance of chimneys. With over 500 Members, the NACS is recommended by all major fuel organisations, including the Solid Fuel Association, HETAS, and OFTEC.

NACS Members work strictly to the NACS Code of Practice © 1982 and Code of Conduct for the cleaning of chimneys.  On completion of work, NACS Sweeps issue an Industry Standard Certificate of Chimney Sweeping, and recommend when future cleaning is necessary.

NACS Chimney Sweeps undertake an extensive training program and have to successfully complete a full assessment prior to becoming and trading as a NACS Member.  All NACS Members must hold valid insurance for Chimney Sweeping, of which they provide a copy of to the Association on an annual basis.  They must also have the correct equipment to be able to undertake the job which is checked at the time of their assessment.  You can search for a NACS Chimney Sweep in your area by visiting the NACS website
