No licence is needed. However, training to use a scissor lift is recommended. The only legal regulations for UK vehicle lifts concern maintaining the lift itself.
All vehicle lifts must undergo a regular examination by a competent person. This means an inspection before the first use and every 6 months after that (HSE803/69). Inspections should also take place following ‘exceptional circumstances’ e.g. a failure, damage or after long periods of being out of use.
A competent person is an objective employee of a specialist maintenance company or vehicle lift supplier, who has enough knowledge and experience of vehicle lifts to detect defects, wear or weaknesses and assess their importance to safety and continued use. This should not be the same person who performs routine maintenance, to ensure they are sufficiently impartial in decision-making.
