While there is no strict legal requirement specifying an exact interval for forklift refresher training, it is strongly recommended by the UK Health and Safety Executive (HSE). Employers have a legal duty under the Health and Safety at Work Act to ensure that forklift operators are properly trained and competent, which includes periodic refresher training to maintain safety standards.

Regular refresher training helps to ensure that operators continue to follow safe practices, reduce the risk of accidents, and comply with safety regulations. Neglecting this training could lead to unsafe working conditions and potential legal repercussions, making refresher training a critical component of workplace safety for forklift operators.
