On the basis of the information provided by the OP, this is over the top.
This sounds like a legal (not tax) question. Isn't the OP's concern whether the sale by the individual was private or business (the latter affording a greater level of protection to consumers)? Presumably the repair work was done by the individual's company and, to that extent, it and disaggregation for VAT purposes is irrelevant. The crux of it is the capacity in which the individual made the sale, was it private (caveat emptor) or business?
