Sinking Fund for Leasehold Property Explained
If you own a leasehold flat, you may pay into a sinking fund, sometimes called a reserve fund, on top of your service charge. It is money set aside for big, occasional repairs, so that no single leaseholder gets landed with a huge one-off bill. This guide explains what a sinking fund is, how it differs from the service charge, and what rights you have over the money.

Key takeaways
- A sinking fund covers major, infrequent works like a new roof, lift or external repainting, spreading the cost over years.
- It is separate from the service charge, which pays for day-to-day running costs like cleaning and insurance.
- The money must be held in trust in a separate account, and your landlord can only collect it if the lease allows.
- Reserve fund and sinking fund mean the same thing in most English and Welsh leases and are used interchangeably.
What is a sinking fund?
A sinking fund is a pot of money that leaseholders build up over time to pay for expensive works that only come around every few years. Think of a new roof, replacing a lift, redecorating the outside of the block, or overhauling the heating system. Rather than hit everyone with a massive bill in the year the work happens, the cost is collected gradually so it is there when needed.
The idea is fairness: it ensures everyone who has lived in the building contributes to the big jobs, not just whoever happens to own their flat in the year the roof needs replacing.
Sinking fund vs service charge
It helps to keep the two apart:
- Your service charge covers the regular, predictable costs of running the building, such as cleaning communal areas, gardening, lighting, buildings insurance and management fees. You pay it every year.
- The sinking fund is for the large, occasional costs that do not fit a normal year's budget. You usually pay into it through your service charge, but it is earmarked for the future.
So a portion of what you pay keeps the lights on now, while another portion quietly builds a cushion for the big jobs later.
Reserve fund or sinking fund, is there a difference?
In practice, no. In most leases in England and Wales the terms "reserve fund" and "sinking fund" are used interchangeably. Both describe contributions collected from leaseholders and held on trust to fund significant future spending on the building. If your lease uses one term, do not worry that it is different from the other.
Your rights over the money
The law gives leaseholders some important protections:
- It must be allowed by your lease. A landlord can only demand payments into a reserve fund if the lease specifically permits it. If it does not, they cannot make you pay in.
- It must be held in trust. By law, the money must be kept in a separate account, ring-fenced from the landlord's own funds, for the benefit of leaseholders.
- You can ask how it is being spent. Leaseholders have rights to information about service charges and the fund, and can challenge charges that are unreasonable.
Because the money is held in trust for the building, you generally cannot get your share back when you sell. It stays with the property for the next owner, which is worth remembering when budgeting for a move.
What to check before you buy a leasehold flat
Before buying, ask your conveyancer to find out: whether a sinking fund exists, how much is in it, what major works are planned, and whether any large bills (known as section 20 works) are coming up. A healthy fund is reassuring; an empty one before a major repair can mean a nasty bill soon after you move in.
Frequently asked questions
Is a sinking fund the same as a service charge?
No. The service charge covers regular running costs; the sinking fund is a separate pot for big, occasional repairs, though you usually pay into it through the service charge.
Can I get my sinking fund contributions back when I sell?
Usually not. The money is held in trust for the building and passes to the next owner, rather than being refunded to you.
Does every leasehold flat have a sinking fund?
No. It depends on the lease. Some leases require one, others do not, so check before you buy.
