“6.6. As soon as practicable after the end of each Account Year the Landlord shall determine and certify the amount by which the estimate referred to in paragraph (a) of sub-clause (4) of this Clause shall have exceeded or fallen short of the actual expenditure in the Account Year and shall supply the Leaseholder with a copy of the certificate and the Leaseholder shall be allowed or as the case may be shall pay within 15 days of receipt of the certificate of the Specified Proportion of the excess or the deficiency.”
“16. In subsequent exchanges between the appellant’s agent and NHBC it sought to identify under which of the three Buildmark warranties the claim was being made, as that was relevant to the amount of the excess which would be applied. Possibly because of difficulty in ascertaining exactly where the defect had occurred, that question was not one which the appellant was immediately able to answer. It was also of concern to NHBC to establish in what proportions each of the leaseholders were obliged to contribute; it is less clear why so much importance was placed on this. 17. NHBC does not appear at any stage seriously to have disputed its liability to contribute towards the cost of the necessary remedial works, but it has not yet been prepared to commit itself to paying a specific sum. Its position before the first instalment of the advance payments fell due can be seen from the following extract from an email sent on8 June 2016 to the appellant’s agents: ‘In principle we find the claim to be valid as there is damage caused by a defect which is principally what all three policy types cover. What we cannot do at this stage is confirm our liability on each policy type, the excess owed on each policy type and our contribution to each policy types’ liability. Once the tribunal has ascertained apportionment I can advise exactly what NHBC will be liable for.’ 18. NHBC’s reference to the tribunal was to the FTT, at which the appellant had issued two applications under theLandlord and Tenant Act 1985 on31 March 2016 . The first was under section 27A(3) and raised specific questions concerning the appellant’s proposed remedial scheme and the liability of the leaseholders to contribute towards it, while the second sought dispensation under section 20ZA from the statutory consultation requirements in the event that they had not been completed properly. 19. The appellant’s section 27A(3) application asked the FTT to consider its entitlement to a service charge if it were to incur the costs of the proposed remedial works, estimated to be a little over£291,000 , and to determine the liability of each respondent to pay their due proportion of those costs. The determination was said to require consideration of the proportions applicable to each respondent, the reasonableness of the proposed costs, and the adequacy of the section 20 consultation procedures. 20. In its statement of case and evidence for the FTT the appellant did not make it clear under which category of expenditure it considered the cost of the remedial works fell. Nevertheless, in the estimate of expenditure provided with the demand for the first instalment of the advance service charge served on10 June 2016 the apportionment appears to have followed the proportions applicable to the Estate Provision. It certainly did so in the case of the second respondent, which was charged 25.95% of the total, that being the percentage which had always been treated by the appellant as the second respondent’s fair and reasonable contribution towards Estate matters. The basis on which the other leaseholders were charged is less clear, as only the demands themselves have been produced and not the breakdown, but it seems reasonable to assume that the same principle was applied. 21. Applying the Estate Provision proportions to the total of£291,000 which the appellant sought to recover in advance by quarterly instalments from June 2016, each of the private residential leaseholders would be required to contribute between£3,114 and£6,286 (£778 to£1,571 per quarter) while the second respondent was asked to pay£75,514 (or£18,878 per quarter). These are relatively substantial sums, especially for the individual leaseholders. 22. The appellant has made it clear at each stage of the proceedings that it is willing to apply the proceeds of the NHBC warranty to the service charge account when they were received.”
