    Must reserve funds be kept in a separate bank account?

    The question

    A question we are asked regularly by RTM and RMC directors: does the law require the reserve fund to sit in its own bank account, separate from the general service charge account?

    Short answer

    Service charge contributions, including reserve fund contributions, are held on statutory trust under section 42 of the Landlord and Tenant Act 1987 and must be kept separate from the landlord's or managing agent's own money in properly designated client accounts. Whether the reserve fund needs its own distinct account, separate from the general service charge account, depends on the lease and on good practice rather than one universal rule. Section 42A, which provides for designated accounts, depends on regulations that are not in force, so it should not be described as an operative duty. Most well-run blocks hold reserves separately for transparency and cleaner handovers.

    The trust obligation is the starting point

    Section 42 of the Landlord and Tenant Act 1987 provides that service charge contributions paid by tenants of dwellings are held by the payee on trust, to be applied for the purposes set out in the leases and, subject to that, for the contributing tenants. Reserve and sinking fund contributions collected as service charge fall within that framework.

    The practical consequence is not optional. Building money is not the landlord's money and it is not the managing agent's money. It must be held in a way that keeps it identifiable and separate from the agent's or landlord's own funds, so that it can be accounted for and, on a change of agent, transferred.

    Section 42A of the 1987 Act was inserted to require service charge contributions to be held in a designated account, but the substantive requirement depends on regulations that are not in force. Directors should therefore not describe a designated account as an operative statutory duty. The section 42 trust, the lease, and the professional codes are what actually bite.

    Separate from whose money, and separate from what

    There are two different questions here, and they get conflated constantly.

    Separation from the agent's or landlord's own money. This is not negotiable. Client money must be held in properly designated client accounts, and agents subject to client money protection requirements and professional codes have detailed obligations about how those accounts are titled, reconciled and audited.

    Separation of the reserve fund from the general service charge account. This is a different question, and the answer depends on the lease and on good practice rather than on a single statutory rule. Some leases expressly require the reserve to be held separately, or to be invested, or to be held in an interest-bearing account with interest credited to the fund. Where the lease says so, that is binding.

    Why a distinct reserve account is usually the right choice anyway

    Even where the lease does not require it, most well-run blocks hold the reserve separately. It makes the fund visible to leaseholders and prospective buyers. It reduces the risk of long-term money being consumed by day-to-day cash flow. It makes interest attribution straightforward. It simplifies the year-end accounts and the reserve fund note. And it makes a change of managing agent considerably cleaner, because the balance being transferred is unambiguous.

    Where money is pooled, the reserve should at the very least be separately identified in the accounting records and reported as a distinct balance, with a clear statement of what it is held for.

    What directors should check

    Read the lease first: does it require a separate or interest-bearing account, and who is entitled to the interest? Then establish who the account is actually with, how it is titled, and whether the title makes clear that the money is held for the client and its leaseholders. Ask for statements directly rather than relying on summaries. Confirm reconciliation frequency and who reviews it. Check whether client money protection is in place and ask to see the certificate. Consider whether deposit protection limits are relevant to the sums held, particularly where a large reserve is building towards major works.

    Tax and accounting

    Interest on reserve funds and the tax treatment of service charge trusts are technical areas, and the position can differ depending on how the fund is constituted. Boards should take accountancy advice rather than assuming interest is simply theirs to spend. Reserve funds should also be reported clearly in the annual service charge accounts, with the opening balance, contributions, expenditure and closing balance shown.

    On a change of agent

    Reserve fund balances should be identified, evidenced by bank statements and reconciled to the transfer date. A refusal to transfer building money because of a fee dispute is a serious matter, and the trust framework is the reason why. Directors should keep the two issues separate: the fee dispute can be argued on its own merits without the building's long-term savings being used as leverage.

    Setting up and reconciling compliant client accounts is routine work for a managing agent, and is included in our management service for RTM companies.

    Important qualifications

    • The section 42 trust applies to service charge contributions from tenants of dwellings; the detail of what the money can be applied to comes from the leases.
    • Section 42A designated account provisions depend on regulations that are not currently in force.
    • Client money protection requirements and professional codes impose detailed obligations on agents, but those are scheme and membership requirements, not universal statute.
    • Whether the reserve must sit in its own account is usually a lease question; some leases require separate or interest-bearing accounts.
    • Tax treatment of service charge trusts and interest is technical and should be checked with an accountant.

    Practical steps

    1. Read the lease provisions on reserve funds, investment and interest.
    2. Establish which bank holds the money and exactly how the account is titled.
    3. Obtain bank statements directly rather than relying on agent summaries.
    4. Confirm the reserve balance is separately identified in the accounting records even if pooled.
    5. Ask for the client money protection certificate and check it is current.
    6. Agree reconciliation frequency and who on the board reviews it.
    7. Consider deposit protection limits where a large reserve is accumulating.
    8. On a change of agent, reconcile the reserve balance to the transfer date before signing anything off.

    What this means in practice

    How this applies depends on whether you hold the money or contribute to it.

    If you are one of the rtm directors

    • Ask to see the account title, not just the balance, so you can confirm the money is held for the company and its leaseholders.
    • Review a reserve fund reconciliation at least annually at board level and minute it.

    If you are one of the rmc directors

    • Report the reserve fund clearly in the service charge accounts with opening balance, contributions, spend and closing balance.
    • Take accountancy advice on interest and tax rather than treating interest as free income.

    If you are one of the leaseholders

    • Ask how the reserve is held and what it is earmarked for before assuming it has been misused.
    • Use the statutory rights to information and inspection rather than informal speculation.

    Common mistakes

    • Stating that a designated account is legally required

      Section 42A depends on regulations that are not in force. The trust under section 42, the lease and professional codes are the real obligations.

    • Letting reserve money fund day-to-day cash flow

      Pooled money without separate identification makes long-term savings vulnerable to short-term deficits.

    • Accepting a balance figure without bank evidence

      Statements and reconciliations are what prove the money exists and is held correctly.

    • Treating interest as the company's to spend

      Entitlement to interest depends on the lease and the trust; accountancy advice is needed.

    When to seek professional advice

    Most questions on this topic are management questions rather than legal ones, and the two are worth separating. A managing agent can tell you how something works day to day and what it will cost. A solicitor tells you what your rights are and how a Tribunal is likely to view them.

    Speak to a managing agent when

    • Setting up and operating properly titled client accounts for the building.
    • Reconciling and reporting the reserve fund separately and clearly.
    • Checking lease requirements on reserve funds and interest.
    • Evidencing reserve balances during a change of managing agent.
    Request a free block review

    Take specialist legal advice when

    • Accountancy advice on the tax treatment of service charge trusts and reserve fund interest.
    • Legal advice where reserve money appears to have been misapplied or cannot be evidenced.
    • Legal advice where an outgoing agent refuses to transfer reserve balances.
    • Legal advice where the lease is unclear on whether a reserve can be collected at all.
