Difference between cold rent and warm rent?

The basic rent: The price for the space

Let's start with the basics. When we consider the difference between cold rent and warm rent , the cold rent (in Switzerland usually called net rent) is the amount charged purely for the use of the square meters.

It contains:

• The use of living spaces.
• The use of the basement or attic.
• Compensation for the wear and tear of the property.

The base rent (or net rent) is the amount that belongs to the landlord. It covers their mortgage interest, management costs, and profit. When comparing prices, experts often look at the base rent per square meter. However, considering it in isolation is dangerous for your household budget. After all, nobody lives in a cold, dark apartment without running water. This is where the discrepancy between base rent and net rent comes into play. Without the additional costs, the base rent is merely a theoretical figure.

Additional costs: The bridge between basic and total rent

To calculate the total rent (including utilities), you need to add up the additional costs. By law (Swiss Code of Obligations), the landlord may only pass on costs that are directly related to the use of the rented property.

Typical items that make up the difference between cold and warm rent are:

• Heating and hot water: The biggest expense. Oil, gas, district heating or heat pump electricity.
• Building maintenance: The wage for the building manager who cleans the stairwell and shovels snow in winter.
• General electricity: lights in the stairwell, electricity for the elevator or the washing machine in the communal kitchen.
• Wastewater and garbage collection: basic fees charged by the municipality.

Important to know regarding cold and warm rent : Costs for repairs, renovations, or new heating systems must not be hidden in the additional costs. These are already included in the cold rent. Therefore, if you check the breakdown of cold and warm rent and find a "repair fund" listed, this is illegal.

The all-inclusive rent: advance payment vs. flat rate

The gross rent (or all-inclusive rent) is the sum of the base rent plus utilities. But here's the rub. The gross rent is often not a fixed price. When we talk about base rent and gross rent , we have to distinguish between two billing models that have a significant impact on your wallet.

1. The advance payment model (The Standard)

Here you pay a monthly advance payment (on account) for utilities. The base rent and total rent stated in the contract are therefore provisional. The landlord will provide a final statement once a year.

• Were the actual costs higher than your advance payments? You have to pay the difference.
• Were they deeper? You'll get your money back.

The risk when comparing the base rent and the total rent (including utilities) is that landlords sometimes deliberately set the advance payments too low in the advertisement to make the apartment appear cheaper. The "optical" total rent is low, but the additional payment is inevitable. Therefore, a critical look at the ratio of base rent to total rent is essential.

2. The flat-rate model

Here, the utilities are a fixed flat rate. The base rent and total rent are final. If the house uses more heating oil than expected, that's the landlord's problem. If you use less, it's his profit. There are no additional charges and no refunds. With this model, there are no surprises regarding the base rent and total rent .

What is NOT included in the total rent?

A common misconception regarding cold and warm rent concerns private consumption costs.

Even if you transfer the total rent (including utilities) to the landlord, this almost never covers everything in Switzerland.

• Private electricity: The electricity you use in your apartment for TV, computer, and cooking is paid directly to the electricity company. It is not included in either the base rent or the total rent .
• Internet/TV/ Serafe : These fees are also added "on top".

So when planning your budget, it's not enough to just know the difference between the base rent and the total rent (including utilities ). You also need to factor in an additional 50 to 100 Swiss francs per month for electricity and utilities, which are completely separate from the base rent and total rent .

Why comparison is important

Why are we so fixated on the terms "cold rent" and "warm rent" ? Because it's the biggest lever for comparison.

Imagine two apartments:

• Apartment A: Base rent 1,500 CHF + additional costs 300 CHF = Total rent 1,800 CHF.
• Apartment B: Base rent 1,600 CHF + additional costs 100 CHF = Total rent 1,700 CHF.

At first glance, apartment A appears cheaper in terms of base rent. However, apartment A might be a poorly insulated older building (high heating costs), while apartment B is a new Minergie-certified building (low utility costs). At the end of the month, apartment B is cheaper, even though the base rent is higher. Therefore, a savvy tenant always considers the total cost, including both base and total rent . A building's energy efficiency significantly impacts the ratio of base to total rent .

Conclusion

The distinction between basic rent and total rent is more than just semantics. It forms the basis for financial security when it comes to housing. Basic rent (net rent) is the price for the living space, while total rent (gross rent) is the price for housing including heating and water.

The biggest risk lies in setting the advance payments too low, which makes the monthly costs appear lower but leads to additional payments at the end of the year. Therefore, always check the ratio of base rent to total rent (including utilities) before signing a contract and ask for the utility bills from the last three years. Only then can you see if the difference between base rent and total rent stated in the advertisement is realistic. Never blindly rely on the information in the advertisement ; always do the math.

If you are unsure whether the additional costs in an advertisement are realistically calculated or how the ratio of cold and warm rent compares to the market for a particular region, Loft offers neutral data analyses to protect you from hidden cost traps.

Glossary

• Net rent (basic rent): The base price for the use of the premises excluding operating costs. In the context of basic and warm rent, this is the amount that remains with the landlord.
• Gross rent (including utilities): The total rent including all additional costs (heating, water, caretaker). It is the sum of the base rent and the net rent components.
• Advance payment: Monthly prepayment towards utilities. If it is too low, there will be a gap between the planned base rent (including utilities) and the actual costs (additional payment due).
• Utility bill: The annual statement of actual costs. It shows whether the difference between the base rent and the total rent was calculated correctly.
• Flat rate: A fixed amount for additional costs. The base rent and total rent are final; there are no subsequent charges.
