“We hire our vending machines in our office. Whose responsibility is it to make sure they’re PAT tested?”
This is a simple one really – it’s up to the machine owner to ensure that the equipment they provide you is safe. The same applies for all hired appliances, from vending machines & water coolers, to smaller short-term hired appliances that you may have. This doesn’t mean you can ignore them and forget about them though, make sure they have been recently tested when you accept delivery of the item and if they don’t get re-tested when they are supposed to be then contact the hire company. If the appliance was to cause a fire or injury and it’s on your business premises it’s going to inconvenience you much more!
