You can be held legally liable for any accidents caused by products you provide your customers, even if you’re not the manufacturer. As the installer or supplier of the faulty product, you will almost always be the first point of contact for your customers. And if you’re unable to identify the manufacturer of the product, there’s no way to pass any compensation claims onto them. If it then materialises that the manufacturer is no longer trading, it’s even more unlikely you’ll be able to recover costs and will, therefore, be held responsible for all payments.
