What is Sinking Fund (Leasehold)?
A reserve fund built up gradually from leaseholders' service charge contributions to pay for large, infrequent future costs, such as roof or lift replacement, without needing a sudden one-off bill.
Full Definition
A sinking fund (also called a reserve fund) is a pot of money built up gradually over time from leaseholders' service charge contributions in a block of flats, specifically earmarked to cover large, infrequent future costs -- such as replacing a roof, repainting the exterior, or installing a new lift -- rather than leaving leaseholders exposed to a single, large, unbudgeted bill in the year the work is actually needed. Contributions to a sinking fund are usually collected as a fixed additional element of the annual service charge, calculated by the landlord or managing agent based on a long-term maintenance plan estimating when major items will need replacing and how much they are likely to cost, spreading the financial impact evenly across many years rather than concentrating it in the specific year the work happens. Under the Landlord and Tenant Act 1985, money collected for a sinking fund from residential leaseholders must legally be held in a designated trust account, separate from the landlord's own general funds, and used only for the purposes agreed in the lease, giving leaseholders some protection if the landlord or managing agent were to become insolvent. A well-funded sinking fund is often seen as a positive by prospective buyers of a leasehold flat, since it reduces the risk of an unexpected large service charge demand shortly after purchase, whereas a poorly funded or non-existent sinking fund can mean a buyer effectively inherits a looming future bill for major works that previous leaseholders did not adequately save toward.
