To show compliance all companies we trade with must complete a declaration on this every year.

Invoicing for work

We use an electronic purchase-to-pay system for raising purchase orders and paying invoices. To be paid promptly, make sure you’ve received a valid purchase order from CHP before beginning any works or services and reference the purchase order number on your invoice.
