High performing and safe sub-contractors and suppliers.

Every business is dependent on its supply chain, with every chain only as strong as its weakest link. By sharing our values with our supply chain, we can work together to deliver them and achieve our vision to become the industry’s partner of choice. Our Supply Chain Charter was introduced in 2013, as the first initiative to be addressed within Focus 30. It forms the basis for the collaborative relationships formed between HE Simm and its supply chain. Read our Supply Chain Charter.
