The trust mark for properly documented garden rooms.
GARSA is the Garden Room Standards Association: a proposed approved-installer, certification and public-register scheme created to raise standards in the UK garden room industry.
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
