“…if contractors want the benefit of these provisions, they are obliged, in return, to set out their interim payment claims with proper clarity. If the employer is to be put at risk that a failure to serve a payless notice at the appropriate time during the payment period will render him liable in full for the amount claimed, he must be given reasonable notice that the payment period has been triggered in the first place.”; (b) In Henia Investments v Beck Interiors Limited[2015] EWHC 2433 (TCC) Akenhead J said: “…the document relied upon as an Interim Application … must be in substance, form and intent an Interim Application stating the sum considered by the Contractor as due at the relevant due date and it must be free from ambiguity. In this context, the Interim Application should be considered in the same light as a certificate. If there are to be potentially serious consequences flowing from it being an Interim Application, it must be clear that it is what it purports to be so that the parties know what to do about it and when.”
