The contract which may apply for the scenario (i) concerning the installation of a gas central heating in M. Frost’s bungalow is the contract of work and materials. The main purpose of this contract is the supply of services based on the labour and skills of the provider, in spite of the eventual materials utilised. This was the case in Robinson v Graves (1935) where an artist was committed to paint a portrait. The Court of Appeal said that Grave (the buyer) had purchased Robinson’s skills, even if materials, considered as secondary, had been used (e.g.: paints). (Elliot & Quinn, 2003) Work and materials contracts are ruled by the Supply of Goods and Service Act 1982 (as amended by the Sale and Supply of Goods Act 1994 and the Sale and Supply of Goods to Consumers Regulations 2002).
