A fair split is not only a percentage. It is a documented cost pool, a documented allocation rule and a breakdown every tenant can trace to evidence.
“Common-area cost”, “service charge”, “operating expense” and “utility recharge” are often used as if they mean the same thing. The lease and local rules decide the boundary; the calculation must state it.
Common-area operating costs arise from spaces, systems or services that support more than one occupier: shared lighting, circulation areas, lifts, central plant, security, cleaning, waste or landscaping. A service charge is the commercial mechanism used to recover the agreed pool. A utility recharge is the pass-through of a utility cost under the applicable lease and local rules.
Capital works, landlord improvements and a tenant’s directly metered use do not automatically belong in the common pool. Their treatment depends on the lease wording and the local rule. This guide explains the operating calculation; it is not legal or tax advice.
The more directly a cost can be measured or assigned, the less needs to be shared. Meter tenant use and major common systems first; allocate only the genuine remainder.
No single key is fair for every line. Choose the basis before the period opens, state why it fits that cost and keep the denominator fixed for the period.
Consider a hypothetical 8,000 m² retail park with ten units. A 240 m² unit occupies 3% of the total leasable area. The figures below illustrate the method, not a client result.
The number is defensible because the tenant can recompute it. Commercial concessions such as caps or anchor discounts may still apply, but they must appear explicitly; a discount for one occupier cannot hide as unexplained extra cost for everyone else.
Vacancy is where an allocation model reveals whether it is honest. The applicable lease and jurisdiction decide recoverability, but the calculation must show whose responsibility the empty unit and its share became.
A fixed denominator prevents occupied tenants’ percentages from rising only because another unit became vacant. If the commercial arrangement uses a different vacancy treatment, state the rule, legal basis, effective date and affected pool before the period is billed.
Compare approved actual costs with tenant advances, retain the meter and invoice evidence behind each line, and carry corrections forward visibly instead of rewriting a closed period.

Only if the lease and applicable market rules place it in the recoverable pool. The statement should name the fee, basis, cap or fixed amount rather than bury it inside another line.
Metered consumption is strongest when it reliably identifies the user. Area is a common fallback for genuine shared services. Fairness depends on matching the key to the cost and agreeing it in advance.
Prospectively, through the agreement and process required by the lease. A closed period should not be re-keyed silently; preserve the original calculation and any authorised correction.
The unit has no occupier to pay, but its costs do not disappear. Responsibility follows the lease and the local rule, and should remain visible instead of being automatically spread over occupied tenants.
Treatment varies by lease, market and law. Keep capital items separate unless the lease clearly permits recovery and explains amortisation or caps.
Show the concession and the party carrying its effect. The remaining tenants should not discover an undisclosed discount only because their percentages no longer reconcile.
Reconcile the main meter with tenant submeters and individually metered common systems. Investigate the unexplained remainder before allocating it.
No. Recoverability, VAT, mark-ups and disclosure requirements depend on the lease and jurisdiction. Use local legal and tax advice; use the meter and calculation trail to support the operational facts.
Bring one cost pool, one allocation schedule and the meters behind it. We will show where the evidence is complete, where vacancy or a denominator changes the result and what Volts can preserve.
