Building contract – Contractor. The Technology and Construction Court held, first, that an interim payment notice had been valid. Second, it held that, when read together, an email and its attachments constituted a valid pay less notice in a dispute concerning construction services provided by the defendant company to the claimant NHS trust. There was no need for a pay less notice to have that title or to make specific reference to the relevant contractual clause in order to be valid. The question was whether, viewed objectively, it had had the requisite intention to fulfil that function.
