About Guymark

Guymark UK was established in 1991, specialising in the provision and support of the highest quality medical equipment for the audiological, ENT and hearing conservation markets.

In 1995, we established our sister company, Houseman-Caltec International, to ensure the highest standard of support in calibration and service of audiological equipment. In 1997, Guymark UK and Houseman-Caltec merged to form a total service company.

In July 2000, we became an ISO registered company and are currently registered to ISO 9001:2008. Our Calibration Laboratory was awarded a UKAS accreditation for the calibration of audiometers in September 2008 and in December 2009 we achieved certification to ISO13485 for the manufacture of medical equipment.

We are the exclusive distributors in the UK and the Republic of Ireland for GSI, Maico and MedRx audiological equipment, along with Otopront ENT equipment . We also supply PATH Medical audiological equipment, Opticlar ENT equipment, Casella sound level meters and QuietStar booths & suites. We supply a complete range of consumables and accessories for all of our equipment which is also compatible with other brands, we pride ourselves in being able to source products our customers require. 

To ensure an efficient service, we divide the UK into managed regions which provide nationwide service to the public and private healthcare sectors, industry, education and public services.
