Outgoings are an essential part of any commercial lease agreement. They represent the extra costs tenants pay in addition to their base rent to cover the building's operational and maintenance expenses.

Understanding what outgoings include, how they are calculated, and your rights to transparency is crucial for managing your total occupancy costs. Many tenants focus on rent negotiations without fully appreciating how outgoings can affect their bottom line.

What's Included

Typical outgoing categories.

The exact items tenants are responsible for should be clearly listed in the lease agreement.

Building Operations

  • Local authority rates
  • Building insurance premiums
  • Common area utilities
  • Rubbish collection

Maintenance

  • Common area maintenance
  • Cleaning and landscaping
  • Parking area upkeep
  • Building WOF costs

Compliance

  • Fire safety measures
  • Health and safety
  • Building certifications

Management

  • Property management fees
  • Building administration
Proportional Allocation

How your share is calculated.

Usually, tenants pay a proportion of a building's total outgoings based on how much of the building they occupy. For instance, if you lease 25% of a building's usable area, you are likely responsible for 25% of the outgoings.

Net lettable area (NLA) as a percentage of total building NLA
Gross floor area as a percentage of total building area
Fixed percentage specified in the lease schedule

Example: 25% Share

You

Total Building Outgoings: $100,000

Your Share: $25,000

Transparency

Your rights regarding outgoings.

Landlords should provide a clear breakdown of outgoings to maintain transparency. The standard Law Association lease form requires landlords to provide annual budgets.

Annual Budget

Landlords should provide you with a budget at the start of each outgoings year showing estimated costs.

Year-End Reconciliation

At the end of each year, actual costs are compared to the budget. You may receive a refund or be asked to pay additional amounts.

Right to Question

Tenants have the right to question or even audit outgoings expenses if something seems unclear or unreasonable.

Watch Out

Common issues with outgoings.

Capital expenditure passed through as outgoings

Some landlords attempt to include capital improvements (such as building upgrades) as outgoings. Generally, capital expenditure should be borne by the landlord, not passed to tenants.

Management fees that seem excessive

Property management fees are a legitimate outgoing, but they should be reasonable and in line with market rates. Query fees that seem disproportionate to the services provided.

Outgoings not specified in the lease

You should only be liable for outgoings that are clearly specified in your lease. If a new charge appears that was not contemplated in your lease, you may be entitled to dispute it.

Significant variations from budget

While some variation is normal, significant increases from the budgeted amount should be explained. The seventh edition lease requires landlords to advise tenants of material increases promptly.

Practical Steps

Budgeting for outgoings.

1

Request Historical Data

Ask for records of past outgoings to estimate future costs and identify trends.

2

Plan for Increases

Operating expenses usually rise over time. Build in a buffer for potential increases.

3

Negotiate Caps

Consider negotiating limits on the annual rise in outgoings, especially for items landlords can control.

4

Understand Exclusions

Clarify which costs are included in base rent and which are additional outgoings.

What to check in your lease

The specific items included in outgoings
Your proportionate share and how it is calculated
Whether there are any caps on outgoings or annual increases
The landlord's obligations to provide budgets and reconciliations
Your rights to request information and audit costs
What happens if the building has vacant space (who pays their share)
