After moving in and settling down, the first thing on my to-do list was to figure out the various bills. I had heard before coming to Spain that utilities weren’t cheap, so I wasn’t sure what to expect. I recently received my first complete bill, so I’m sharing the details to give future newcomers a reference for what to expect for these gastos (expenses) like electricity, water, and gas when renting in Spain.

Electricity Bill
Electricity is definitely a major living expense, especially when using heating in winter or air conditioning in summer. The structure of Spanish electricity bills is a bit complex, unlike a simple flat-rate system. It’s mainly divided into two parts:
- Fixed Cost (Término de Potencia): This is the ‘contracted power fee’ you agree to with the electricity company. You have to pay this even if you don’t use a single kilowatt-hour. The higher the contracted power, the more expensive the fee. For a shared apartment, a contract for 3.45 kW to 4.6 kW is usually sufficient.
- Variable Cost (Término de Consumo): This is the charge based on your actual electricity consumption. Most contracts now use time-of-day pricing, typically divided into three periods: peak (Punta), flat (Llano), and off-peak (Valle). The off-peak rate is the cheapest. Therefore, running high-consumption appliances like the washing machine or dishwasher on weekends or late at night can save you a lot of money. My electricity bill this month was about 45 euros for two people, without using much air conditioning, which is quite economical.
Water Bill
The water bill is much cheaper compared to electricity. Similar to electricity, it includes a fixed service fee plus charges for your actual water consumption. Additionally, the bill often includes fees for waste collection and sewage treatment. That’s why when you look at Spanish utility bills, you’ll notice quite a few different items. For the two of us, the monthly water bill is around 25 euros. This amount doesn’t fluctuate much, unless you take a bath every day.
Gas Bill
Regarding your home’s heating, which is a key part of your Spanish utility bills, if your hot water and heating run on natural gas, this expense can be significant in the winter. The gas bill’s structure is very similar to the electricity bill: a fixed service fee plus a consumption-based charge. With gas heating in winter, a monthly bill of 80-100 euros is quite normal. If your heating is electric, then the electricity bill will be daunting. So, when renting, make sure to ask about the heating system! If it uses gas bottles (bombonas), it might be cheaper, but you have to replace them yourself, which can be a hassle.
Here is a rough monthly cost estimate based on my own and my friends’ experiences:
| Expense Item | Summer Cost | Winter Cost |
| Electricity | 40 - 60 euros | 60 - 90 euros |
| Water | 20 - 30 euros | 20 - 30 euros |
| Gas | 15 - 25 euros | 70 - 120 euros |
Internet | 25 - 40 euros | 25 - 40 euros |
In total, electricity, water, and gas combined will cost around 80-110 euros per month in seasons without heating. In winter, this can spike to 150-200 euros or even higher. Of course, this heavily depends on your lifestyle, the size of your apartment, and the energy efficiency rating of your appliances. I hope this breakdown is helpful!
