“1.3.6 “Final Account” means the account submitted by the Sub-Contractor to the Contractor in accordance with Clause 28.1 or 28.6 and assessed and agreed in accordance with clause 28.7. 1.3.7 “Final Account Statement” means the document submitted by the Contractor to the Sub-Contractor confirming the value agreed in full and final settlement of all payment due relating to the Sub-Contract in accordance with clause 28.7.” (b) Clause 28.5 provided: “Within 4 weeks of completion of the Sub-Contractor Works in accordance with the Sub-Contract, the Sub-Contractor shall submit to the Contractor its proposed Final Account for the Sub-Contract Price adjusted only in accordance with the terms of the Sub-Contract Order. The Sub-Contractor shall append to its Final Account copies of all Variation build-ups, whether or not such information has been previously provided, identifying the provision of the Sub-Contract which permits such recovery and referencing and attaching a copy of the relevant instruction and all other pertinent information in support of such to allow the Contractor to make accurate assessment of the Final Account. The Sub-Contractor shall be bound by and shall not be permitted to add to or otherwise adjust its proposed Final Account after submission.” (c) Clause 28.6 provided: “The Contractor shall assess the proper amount due for payment in respect of the Sub-Contractor’s Final Account based on the information submitted in accordance with clause 28.5 and shall notify the Sub-Contractor accordingly within 13 weeks of receipt of the Sub-Contractor’s proposed Final Account or such longer time as would be reasonable in all the circumstances taking account of the Main Contract conditions. In the absence of a proposed Final Account submission from the Sub-Contractor in accordance with clause 28.5, the Contractor may value the proper amount due for payment in respect of the Sub-Contractor’s Final Account on a fair and reasonable basis and notify the Sub-Contractor accordingly. In either case, if such notification is not dissented from in writing by the Sub-Contractor within 14 Days, then the notified figure will be deemed to have been agreed and will be binding on the parties.” (d) Clause 28.7 provided: “No payment shall be due to the Sub-Contractor in respect of the Final Account until it has been agreed and confirmed in accordance with this clause 28.7. Once agreed, the Contractor shall within 14 days submit a Final Account Statement to the Subcontractor to confirm the figure is in full and final settlement of all payment due to the Sub-Contractor arising out of the Sub-Contract. The Sub-Contractor shall then sign and return the Final Account Statement to the Contractor together with its application for the agreed Final Account Figure less Retention. The amount due in respect of the Final Account shall be the amount stated in the signed and returned Final Account Statement less: 28.7.1 a deduction in respect of Retention at 50% of the percentage rate stated In Appendix 6; and 28.7.2 the sum of the amounts paid in previous Interim payments.”
“But it seems to me that, 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) Henia Investments Inc v Beck Interiors Limited[2015] BLR 704 , in which Akenhead J said at paragraph 17: “Although it is not apt to talk in terms of conditions precedent, I consider that the document relied upon as an Interim Application under Clause 4.11.1 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.” (c) Severfield (UK) Limited v Duro Felguera UK Limited[2015] EWHC 3352 (TCC) , in which I said at paragraph 32: “The whole point of the default provisions in the 1996 Act, by which an employer becomes liable for the sum notified, is to encourage simplicity and clarity. If X notifies Y of a claim for£1,000 , and Y does not respond in the prescribed time to challenge that claim,£1,000 becomes due because it is the notified sum. Introducing the possibility of a partial claim for£675 , by reference to a gloss put on an accompanying spreadsheet, would be to confuse the simple system of notification envisaged by the 1996 Act.” (d) Jawaby Property Investment Limited v The Interiors Group Limited[2016] BLR 328 , in which Sue Carr J said at paragraph 59: “Whether or not this conclusion can be said to lead to a harsh result for TIG, this is an area where, as the authorities make clear, there is little scope for latitude. If a contractor wishes to have the benefit of the interim payment regime such as that contained in the Contract, then its application for interim payment 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.” (e) Surrey and Sussex Healthcare NHS Trust v Logan Construction (Southeast) Limited[2017] EWHC 17 (TCC) , in which Mr Alexander Nissen QC (sitting as a Deputy High Court Judge) set out a number of the above passages and concluded: “37. The principles identified in these three cases are not in dispute. There is a high threshold to be met by any contractor who seeks to take advantage of these provisions whereby a sum automatically becomes payable if a timely employer's notice is not served.”
