The UK's leading supplier of medicinal gases and related services to healthcare organisations


Throughout hospitals, ambulance services, treatment centres, GP surgeries, veterinary and dental practices, a wide range of medicinal gases are used to provide crucial care and improve the lives of patients. 

BOC provide products for almost every hospital department, from nitrous oxide for anaesthesia to liquid helium for cooling the magnets of MRIs. Our services also extend to primary care and increasingly into patients’ homes, through our home oxygen service. 

BOC Healthcare has been a major force behind many important developments. We’ve been instrumental in developing gases like ENTONOX® and in promoting the healthcare profession’s understanding of the clinical benefits of oxygen, HELIOX21 and other gases.

In recent years the healthcare division of BOC has diversified and developed from being the major supplier of hospital gases to becoming one of the leading suppliers of clinical services.  These services include: Home Oxygen, and Clinical Services.

BOC’s Cryospeed service gives you access to larger volumes of oxygen, nitrogen and carbon dioxide in cryogenic liquid form. These are stored in fully maintained stainless steel vacuum-insulated vessels on your site and are filled by our Cryospeed operators.
