The Landlord’s Arithmetic: Auditing a 2027 Service-Charge Budget Before the First Demand

Service-charge budgets for 2027 are arriving in tenant inboxes this winter, usually accompanied by a payment-on-account schedule that starts in January or March. For many UK SMEs, the instinct is to file the document, note the increase and move on. That is a mistake. A service-charge budget is an estimate of recoverable expenditure, not a fixed tax on occupation. It should be capable of explanation, line by line, and it should be tested against the lease before the first demand is paid.
Begin with the lease, not the spreadsheet
The lease defines what can be recovered, from whom and on what basis. Before comparing totals, identify the service-charge clause, the recovery mechanism, any caps or exclusions, the treatment of insurance, management fees, reserves and interest, and the tenant’s right to see supporting information. Commercial leases do not generally provide the same statutory reconciliation rights as residential tenancies, so the lease and any side letters are the starting point.
Check whether the budget is presented on the same basis as previous years. A change from “actual cost” to “estimated cost plus reserve” matters. So does a shift in floor-area apportionment or a new administration charge. If the lease requires the landlord to consult before certain costs are incurred, confirm whether that has happened.
Run a like-for-like comparison
The useful comparison is not simply this year’s budget against last year’s budget. It is the 2027 budget against the 2025 and 2026 outturns, adjusted for known changes. Ask for a line-by-line bridge: what was spent, what is now forecast and why. Look for movements that outpace inflation, new contract costs, one-off works presented as recurring items, and costs that have been reclassified rather than reduced.
A simple table works well. List each service heading, the 2025 actual, the 2026 actual or latest forecast, the 2027 budget and the variance in both cash and percentage terms. Add a column for the landlord’s explanation. Where the budget is expressed per square foot or as a percentage of a total, recalculate it. Arithmetic errors and inconsistent apportionment are more common than they should be.
Test the caps, exclusions and discretion clauses
Many service-charge disputes turn on a single clause. A cap may be fixed in cash, indexed, cumulative or expressed as a percentage increase. An exclusion may remove capital expenditure, improvements, costs recoverable under insurance, or works that enhance the landlord’s asset rather than maintain it. Management fees may be capped or limited to a percentage of expenditure. Reserve funds may be permitted, but their balance and forecast should still be visible.
Pay attention to wording that gives the landlord discretion. “Reasonable” costs still require evidence. “Generally accepted accounting practice” does not excuse a lack of breakdown. If the lease allows recovery of professional fees for managing the service charge, check whether those fees are included once or twice. If it permits interest on late payment, check that the budget is not treating an estimated charge as overdue before it has fallen due.
Understand the payment-on-account rhythm
Payment on account is a cash-flow mechanism, not a final settlement. The landlord estimates costs, divides them across tenants and reconciles later. The lease should set out when interim demands can be issued, how they are calculated and when a reconciliation statement must be provided. If the reconciliation is late, that does not automatically justify withholding payment, but it is a legitimate point to raise and document.
Before paying, request the supporting schedule: the apportionment calculation, the underlying contracts for major items, the reserve-fund statement and the previous year’s reconciliation. Ask whether the budget includes costs that are still subject to dispute. If you pay under protest, say so in writing and reserve your rights. Take legal advice before withholding any sum, because the consequences under the lease can be severe.
Build a challenge pack, not a complaint
A challenge is more likely to succeed if it is specific and quantified. Assemble a short cover letter, a table of queries and a document request. Identify the three or four largest variances and ask for the evidence behind them. Propose a meeting with the landlord’s managing agent. Set a reasonable deadline for a response and keep a record of every exchange.
Distinguish between a budget query and a reconciliation dispute. The budget is forward-looking; the reconciliation is backward-looking. Raising both at once can muddy the process. If the lease provides for an accountant’s certificate or an audit right, check the deadline and the cost before relying on it. For larger or more complex estates, a chartered surveyor or property litigation solicitor may be worth instructing, particularly where the sums at stake exceed the cost of advice.
The bottom line
A 2027 service-charge budget is a planning document, but it is also a test of the landlord’s transparency. UK SMEs that compare the figures to actuals, test the lease terms and ask for evidence before the first payment on account will be in a stronger position to challenge errors and to budget accurately. The exercise should be diarised now, while the budget is fresh and the first demand is still ahead.
