VENSAV3180 - materials purchased in bulk

Installers often buy materials in bulk and in separate batches and so consideration needed to be given to how the cost of these materials was to be valued for the purposes of the 60% test. Where the installer tracked the items from purchase to installation, this was be used as the basis for determining the cost of the materials. Otherwise, HMRC accepted any fair and reasonable assessment of the cost of materials used for an installation. Evidence of the cost of materials, in the form of normal business records, was to be retained by the business.
