Some hirers offer a waiver, and many contractors rely on it rather than taking out their own insurance policies. But it isn’t always the best option, for two reasons.
First, the hirer’s waiver may only cover a limited range of risks, and may not cover accidental damage to the plant. Having your own insurance can give you more protection.
Second, it may be cheaper to insure hired-in plant yourself, particularly if you hire plant regularly. An annual policy that covers all the plant you hire during the year will usually work out cheaper than paying for a waiver each time you hire something.
