Reserve Funds and Sinking Funds: A Guide for Blocks

Roofs need replacing. Lifts wear out. Buildings need redecorating every few years. These big, predictable costs are exactly what a reserve fund — sometimes called a sinking fund — is for. A well-managed one is the difference between a planned expense and a panicked bill.

What is a reserve fund?

A reserve fund is money set aside over time, through the service charge, to pay for major future works. Instead of hitting every leaseholder with a sudden five-figure bill when the roof fails, the cost is spread across the years leading up to it.

Why every block benefits

• Large costs become predictable rather than shocking.
• Leaseholders pay gradually rather than all at once.
• It is fairer across residents who come and go over time.
• Buildings get maintained instead of neglected for lack of cash.

Transparency is everything

Reserve funds only work if residents trust them. That trust depends on transparency: where is the money, how much is there, and what is it earmarked for? When the balance and the plan are visible to everyone, contributions feel fair. When they are opaque, suspicion grows.

Keep residents in the loop

Sharing the reserve fund balance and the planned works in your block's shared space — and recording the decisions about how it is spent — keeps everyone confident their money is being looked after properly.
