The estimates of the roof works cost ranged from £49,800 to £95,130. The cost was to be shared between 8 flats. We paid our share stipulated as £5560.25. FirstPort later refunded it due them breaking the lease. They charged us instead by increasing the reserve fund. *If they just increased our reserve fund share by the £5560.25 stipulated as our proportion on 2021-12-07; that would have been acceptable, instead they increased our reserve fund contributions by 714%. Our service charges thus increased by £6782.58 in 2023, and by £7405.14 in 2024 – a total increase of £14,187.12. We are one of 8 flats, if every flat pays this increase, this is a total of £113,501.76, which is double the maximum estimate of £95,130 required for the major roof works.
