What kind of certification do I need to become a forklift driver?

Can you recommend me any qualified school in London that teaches how to operate heavy machinery?

The role of a forklift truck driver can be monotonous but it is important to keep full attention at all times. The job usually requires the worker to stack and move goods around a warehouse while maintaining awareness of colleagues working around him/her to avoid accident or injury. The job is ideally suited to someone with experience in driving, and many forklift drivers have worked in some other driving role before taking up the position
All forklift drivers must obtain a license to drive the vehicle and there are special training courses designed for those who want to go into the business. The driver must get the Certificate of Professional Competence (CPC). Most employers will look for reliable candidates with a good all-round education
Forklift truck driving pays around £14,665 per year for inexperienced or new drivers, while the average is around £18,579. Experienced or senior drivers may earn up to £20,000. A forklift license also acts as a stepping stone to other driving jobs down the line.
