What it covers and whether it is required

Membership is voluntary. A sweeping certificate records the service; it is not Building Regulations approval for a new appliance or permission to alter a gas installation.

Joining requirements and costs

NACS describes training routes for newcomers and sweeps without existing qualifications, with assessment and membership requirements for the appropriate route. Its Code of Conduct requires valid insurance. Check the current application and continuing requirements for your experience.

Check the current fees with National Association of Chimney Sweeps before applying. Ask whether the quotation includes application, assessment, renewal and any per-job charges. Use published fees or ask for a written quotation.

What it means for homeowners

Use the official sweep search and ask for the NACS Certificate of Chimney Sweeping after the work. Keep it with appliance and maintenance records. Confirm the service scope, especially where a liner, appliance repair or installation is also proposed.
