Utilities

When negotiating utilities, ensure that your lease details exactly how you will be charged. If you must pay utilities, make sure that your meters for electric, gas and water are separate from those of other tenants so that you pay exactly for what you use. 

Typically, utilities that are not separately metered will be divided by percentage of space. For example, if you rent 10% of the space, you might be expected to pay 10% of the utility bills. This can become problematic if you do not use particular services as much as other tenants do.
