Service charge accounting in the UK is the process of recording, reporting and checking the money leaseholders pay towards the running, repair and upkeep of their building. When it is done well, it builds trust and keeps the year end quiet. When it is done badly, it leads to disputes, delayed payments and, in the worst cases, a challenge at tribunal. This guide covers what block managers, managing agents, RTM companies and Residents’ Management Companies in England and Wales need to know in 2026.
What service charge accounts actually show
At their simplest, service charge accounts tell leaseholders what was planned, what was spent and what happens next. They set the actual costs for the year against the budget, show the balancing charge or credit due from each leaseholder and report the position of any reserve fund.
Service charge accounts are not the same as the statutory accounts of an RMC or RTM company. Company accounts report on the company itself, while service charge accounts report on leaseholders’ money for a particular building.
The landlord is legally responsible for the accounts, although in practice the managing agent or the management company usually prepares them. Either way, the lease is the rulebook. It sets out what must be produced, when it is due and who must sign it off, so every year end starts with the lease.
Certified, audited or reviewed?
The level of accountant involvement is determined entirely by what the lease specifies. Some leases require certification, some require an audit, and modern leases increasingly refer to a review‑type engagement. The lease wording is the only authority for deciding which of these applies.
Modern leases usually adopt review‑based reporting, recognising the cost‑benefit balance for leaseholders. These clauses typically expect the accountant to check records and confirm consistency without requiring a full audit.
Older leases often use the word “audit”, but many were drafted before the Companies Act introduced the current legal definition of an audit. In those cases, the term may not reflect today’s statutory audit requirements. A practical judgement is therefore needed: interpret the lease sensibly, consider proportionality, and agree a level of work that satisfies the lease without imposing unnecessary cost.
Because lease wording varies significantly, it is essential to confirm exactly what the lease requires before any engagement begins, ensuring the accountant’s report aligns with the contractual obligation.
The rules every block manager should know
Service charges sit within a well established legal framework. Under section 19 of the Landlord and Tenant Act 1985, costs must be reasonable and reasonably incurred. Section 20 requires consultation with leaseholders before major works that will cost any leaseholder more than £250, or long term agreements costing any leaseholder more than £100 a year.
Section 20B is the rule that catches people out. Costs incurred more than 18 months before they are demanded cannot be recovered unless leaseholders were told about them in writing within that period. Sections 21 and 22 give leaseholders the right to a summary of costs and to inspect the invoices and receipts behind it.
Finally, section 42 of the Landlord and Tenant Act 1987 says service charge money is held on trust for the leaseholders. Alongside the legislation, the RICS Service Charge Residential Management Code sets the professional standard that managing agents are expected to follow.
Looking after the reserve fund
Reserve funds, sometimes called sinking funds, are held on trust and deserve particular care. They should sit in a designated client bank account, separate from the agent’s own money and from the day to day service charge account. The annual accounts should show the balance, contributions, spending and interest clearly.
A realistic year end timeline
Most leases expect accounts within three to six months of the year end, and six months is widely treated as good practice. A typical year end runs in this order.
- 1
Close the year and reconcile every bank account.
- 2
Match invoices to the correct building and cost heading.
- 3
Apportion costs using the percentages in the lease.
- 4
Prepare the draft accounts and reserve fund statement.
- 5
Pass the accounts to the accountant for audit or review.
- 6
Issue the final accounts with balancing demands.
The mistakes that cause the most disputes
Most service charge disputes come from a short list of avoidable errors. Funds get mixed with other money. Costs appear that the lease does not allow. Apportionment percentages are wrong. The 18 month rule is missed, section 20 consultation is skipped or the accounts arrive months late. Any of these can lead leaseholders to the First-tier Tribunal (Property Chamber), where costs may be reduced or disallowed.
What the Leasehold and Freehold Reform Act 2024 means for you
The Leasehold and Freehold Reform Act 2024 brings in stronger service charge transparency, including standard form demands, annual reports for leaseholders, a right to request information and a requirement to provide accounts with an accountant’s report within a set period. Many of these measures are coming into force in stages. Block managers who already produce clear, timely and well evidenced accounts will find the transition far easier.
