Over recent years the way in which premises are inspected has changed from inspectors looking for specific contraventions to the onus being on the duty holder to provide evidence that the working environment is in a safe condition and that safe systems of work are in place. This would include the supply of electricity and gas to the premises through to examination reports for lifting equipment (e.g. lifts, hoists and forklift trucks) and pressure systems (e.g. compressors, calorifier and air receivers).
