STS prides itself on continuously striving to exceed its customer’s expectations and is built on a 360 degree learning platform where mutual trust and co-operation is key. This ensures both STS and its partnering suppliers are continuously learning together to further improve our duty to our customers.  Where possible, we employ long term framework agreements with many of our suppliers using both NEC3 and bespoke contracts.   This enables us to build an excellent working relationship between ourselves and selected suppliers. 

A range of factors are considered when onboarding any new supplier and these include:
