Welcome to Fgas Register.com

...home to the Quidos F Gas company certification scheme, as appointed by the Department for the Environment, Food and Rural Affairs (DEFRA) under the Fluorinated Greenhouse Gases Regulations 2009.

Quidos specialise in certification and accreditation requirements, enabling individuals and businesses to comply with the latest government legislation and laws with the minimum of hassle and inconvenience.

The law now demands that all businesses and individuals completing the installation and servicing of refrigeration, air-conditioning or heat pump equipment (SRAC work), which contains or is designed to contain F Gas refrigerants, must be fully trained and certified to do so. As an industry standard all businesses must obtain a company certificate as evidence that they are fully capable of conducting this work.

The Quidos application and certification service has been designed to allow compliance within a few simple steps.
