Increases in services charges at a waterside development during the coronavirus lockdown have been criticised by residents.
People living at Admirals Quay at Ocean Village in Southampton have received demands, including some that were more than three times the usual charge.
Management company RMG said it was to help resolve "safety issues" with glazing and cladding.
It said it would offer support to anyone having difficulty paying.
The flats in seven apartment blocks - including the 26-story Moresby Tower, the city's highest building - were sold as leasehold with residents having to pay service charges.
