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 600 Members, the NACS is recommended by all major fuel organisations, including the Solid Fuel Association, HETAS (Heating Equipment Testing & Approval Scheme), and OFTEC (Oil Firing Technical Association).

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 a Certificate of Chimney Sweeping and recommend when future cleaning is necessary.

NACS Sweeps stock a comprehensive range of different brushes and tools to tackle the vast variety of chimneys, flues and appliances they meet.

Many Members also carry sophisticated equipment such as smoke generator machines, Power Sweeping Equipment, and CCTV cameras for the testing and surveying of chimneys, and for diagnosing chimney faults on new and existing flue installations.
