Course outline icon

To become OFTEC registered, individuals need to demonstrate competency in oil-fired appliance installation and servicing, which can be achieved through the completion of relevant training. Our oil courses are recognised by OFTEC. 

There are also other requirements to become OFTEC registered, such as having the correct public liability insurance and health & safety policies. Registration requires that both the business and its technicians are registered.

OFTEC registration is not always a legal requirement, but it is highly recommended and often required by insurance companies and regulatory authorities. 

Being OFTEC registered demonstrates a technician's competence in working with oil-fired appliances and ensures compliance with safety standards.
