“…the parties cannot have intended that the landlords should have an unfettered discretion to adopt the highest conceivable standard” per Cairns LJ in Finchbourne v Rodriquez[1976] 3 All ER 581 , 587b See, also, David Neuberger QC (as he then was) in Morgan v Stainer[1993] 2 EGLR 73 . 35. The Appellants contend that it is not reasonable to oblige them to contribute to the cost of carrying out replacement works to the heating systems of each of the other flats when they have at their own expense paid for the cost of those equivalent works to their own Flat. The test of reasonableness is considered on the facts of each case. Scottish Mutual Insurance Co v Jardine (1999) ECGS 43, relied upon by the Appellants, is an example of a case where works undertaken by the landlord, although reasonable in themselves, could not reasonably be charged to the tenant in view of the fact that the remaining period of the tenant’s occupation was limited and the tenant would therefore derive limited benefit from the works: “… vis a vis the Defendant, the totality of the amounts expended by the Plaintiff on the works to the roof was not “reasonably and properly expended or incurred” because these works went significantly beyond what was required for the performance of the Plaintiff’s obligations to the Defendant in respect of the condition of the premises, because considerable monies had been very recently expended upon short-term repairs and there was no evidence that these had been ineffective and because there was no evidence of any continuing leakage and there was therefore no pressing need to commence long-term repairs prior to the end of the Defendant’s term (which end was imminent)”
