Ornamental Horticulture Assurance Scheme - OHAS
OHAS is the ornamental horticulture assurance scheme of the Horticultural Trades Association.
Introducing OHAS
Quality assurance
OHAS is the only UK certification scheme solely dedicated to ornamental horticulture. Unlike other generic quality assurance schemes, the OHAS Standards are specifically designed to meet the specialist needs of our industry. The Scheme and Standards are managed by the HTA Scheme Manager and a dedicated committee made up of OHAS members, ensuring the Standards remain focused on important, relevant requirements.
Scheme Standards - internationally recognised
The Scheme consists of three Standards covering growing, packing, and growing media manufacture. Each Standard is independently audited by NSF Certification Ltd, an internationally recognised, UKAS accredited certification body. This process ensures OHAS members meet and operate at the highest standards of professionalism required by UK and international market places.
Inspection - high professional standards
To achieve certification, OHAS members are audited annually. This gives buyers in the supply chain complete confidence in both product and service, and means OHAS members are committed and confident they are up to date with the latest legislation and best practice.
