Our courses give general knowledge. Where stated, a course is CPD certified: CPD certification records learning time and is not a qualification or licence. No course replaces practical training, supervision or assessment of competence. Never carry out hazardous work (for example at height, with lifting equipment, electricity, gas or machinery) on the strength of a course alone. Terms
