Buy your garden room with more confidence.

A garden room is a serious home improvement investment. GARSA helps homeowners identify professional installers and keep a clear record of the project after completion.

  • Find installers committed to recognised garden room standards.
  • Receive a clearer project handover and documentation pack.
  • Record planning, Building Regulations and electrical documentation status.
  • Keep a verifiable certificate for future sale, insurance or maintenance enquiries.

What a GARSA certificate helps evidence

A GARSA certificate is intended to show that the project was registered by a GARSA Approved Installer and supported by the relevant project documentation.

  • Installer details and membership number
  • Project registration date
  • Warranty period declared
  • Electrical documentation status, where applicable
  • Certificate status and verification link
