OHAS - UK Accredited and Internationally Aligned

OHAS standards are specifically designed to meet the needs of the horticulture industry whilst being aligned to international standards. 

Quality assurance - specific not generic

OHAS is the only UK certification scheme solely dedicated to ornamental horticulture. Unlike other generic quality schemes, the OHAS Standards are specifically designed to meet the specialist needs of the industry. They are managed by the HTA Scheme Manager and OHAS Committee which means the Standards remain relevant to the horticulture industry. 

OHAS - both UK and internationally recognised

The Scheme is UKAS accredited via our Certification Body NSF and the OHAS Grower Standard is both benchmarked against the GLOBALG.A.P Integrated Farm Assurance Flower and Ornamentals Standardand is part of the Floriculture Sustainability Initiative Good Agriculture Practice basket of standards providing the Scheme with international recognition.

The OHAS Packhouse Standard and Growing Media Manufacturing Standards are two dedicated standards written exclusively for ornamental packhouse businesses and manufacturers of growing media, with a focus throughout on quality assurance procedures.

OHAS is a business assurance scheme incorporating a wide range of best practices.  It covers business organisation and management, health and safety, product traceability, plant health and biosecurity, environmental and business sustainability parameters, staff management, training, and welfare, and much more.
