I’ve found conflicting information about this hence why I am asking the question.
My self build house involves the fabrication and constructing on site of a large steel frame. A steel fabricator has done this, now, what can they charge VAT for? I know the cost of service (constructing and fabricating the steel frame) should not be charged to me, however, I am aware I can claim material costs back and so should they be charging VAT on materials? Or, should the whole supply and fit contract be VAT zero rated by them?
Any advice would be great!
