This chapter covers the contracts for the supply of services. It explains that the provision of services is itself an important commercial activity, but many services are provided in the course of other commercial transactions. The Supply of Goods and Services Act 1982 (SGSA) applies to all non-consumer contracts involving the supply of services. The scope of the SGSA 1982 extends to all contracts involving the supply of services, including those for professional services and those which involve the supply or bailment of goods. The chapter also looks at the notion of product-as-service and circular economy before considering the future of goods and services of contracts.
