Zálohy na služby (advances for services) are monthly payments for utilities. They are paid separately from nájemné (rent) and are regulated by a separate law — zákon č. 67/2013 Sb. (Act No. 67/2013 Coll.).
What is included in "služby" (services)
- water
- heating
- elevator
- cleaning of common areas
- waste disposal
Why it is an advance payment, not the final price
Záloha is an estimated prepayment. Once a year, you receive a vyúčtování (settlement), where the advance payments are compared with your actual usage. This results in an overpayment (přeplatek) or an underpayment (nedoplatek).
How to calculate the real cost of housing
Nájemné (rent) + zálohy na služby (advances for services) + what you pay directly to energy suppliers. Looking only at the nájemné (rent) in an advertisement and then being surprised by the bill is a common mistake for newcomers.
