Case No. HT-11-503

62.The inadequacies in the invoices in this case are too numerous to identify comprehensively. The most important were these. First, the invoices failed to identify with any sort of precision what work was the subject of the claim in the invoice. Secondly, if the work was carried out pursuant to particular instructions, those instructions were not identified or listed. Thirdly, no details were given as to rates or any other way in which the sum claimed in the invoice might be broken down and valued. Most of the invoices are one or two line claims for relatively large sums of money with a generic description of what was carried out. They are almost impossible to analyse retrospectively.63.I will take one invoice as typical of so many inadequate invoices on which the material damage claim relied. The invoice of 23 October 2007 from G.B.M Limited, heating, plumbing and gas engineers, was addressed to Mr Barber at The Oak. It was Invoice 40. The invoice then went on: “REF.THE OAK, TEDDINGTONTOTAL: £11000.00PLUS VAT AT 17.5%: £1925.00TOTAL COST:
