"to run, flow, fall or come to or into; to fall (within a period of time, the scope of an argument, etc.)... To devolve or accrue; to supervene... to become through one's own action liable or subject to; to bring upon oneself..." 35. Section 20B refers to the "relevant costs... were incurred"
“(1) if any of the relevant costs taken into account in determining the amount of any service charge were incurred more than 18 months before a demand for payment of the service charge is served on the tenant, then (subject to subsection (2)), the tenant shall not be liable to pay so much of the service charge as reflects the costs so incurred. (2) Subsection (1) shall not apply if, within the period of 18 months beginning with the date when the relevant costs in question were incurred, the tenant was notified in writing that those costs had been incurred and that he would subsequently be required under the terms of his lease to contribute to them by the payment of a service charge.”
"Both Ms Anderson and Mr Baker relied on Capital and Counties Freehold Equity Trust Ltd v BL PLC[1987] 2 EGLR 49 , in which His Honour Judge Paul Baker QC, sitting as a judge of the High Court, construed "incurred" in a lease to be synonymous with "expended" or "become payable"
"17. The question for decision is whether, if the council were to serve a demand that complied with the provisions of the lease for the amount,£39,049.33 , that the LVT has determined to be payable section 20B would operate so as to prevent its recovery. Mr Butler's primary argument was that by the time the letters of18 October 2005 and17 February 2006 were sent the council had incurred the totality of the costs, since completion was on27 August 2005 , and the council's liability to pay the total contract amount arose on that date. In my judgment, however, costs are only "incurred" by the landlord within the meaning of section 20B when payment is made. There is clearly a distinction between incurring liability (i.e. an obligation to pay) and incurring costs, and it is the latter formulation that is used in the provision."
"As it happens, nothing turns on the answer to this question as to precisely when the lessor incurred costs in relation to the subject matter of a particular certificate. The lessor accepts that whichever of the suggested dates is taken as the date on which costs were incurred, those costs were incurred in respect of each of these certificates numbered one to seven more than 18 months before the demand of15th December 2006 ."
"27. Finally, I agree with Ms Eilledge that, so far as discernible, the policy behind s.20B of the Act is that the tenant should not be faced with a bill for expenditure, of which he or she was not sufficiently warned to set aside provision. It is not directed at preventing the lessor from recovering any expenditure on matters, and to the extent, of which there was adequate prior notice. This does not leave the tenant without a remedy for the failure of the lessor to prepare a final account. In the event of wrongful delay by the lessor, the tenant can apply to the court for the taking of an account and, if the lessor's delay is culpable, the lessor will have to pay the costs."
