NO! Unfortunately, this is a common misconception. Since 2008 it has been regulation within the UK and EU that a Conformity certificate (conformity to the correct, and relevant legislation) is required for all lifting equipment and that the equipment itself must be CE marked and / or UKCA marked. In declaring conformity (issuing a conformity certificate) the manufacturer is declaring that all relevant legislation has been met. If you haven’t met said legislation requirements, and there is an incident whilst using the item in question, the HSE will ask to see all the required certificates and information, and if it cannot be produced then there could be significant fines involved, or worse!
