Hi everyone, I just moved into my new home and have finally settled in. I recently received my first utility bill, and to be honest, it was a bit confusing. It’s completely different from when I was renting and the landlord just gave me a single figure. After some research, I’ve started to figure it out, so I wanted to share what I’ve learned, especially for those who are also planning to buy a home or have just moved to Spain.
Electricity Bill
The electricity bill in Spain is the most complex one. It’s mainly divided into two parts: the fixed power charge (potencia) and the actual consumption charge (consumo). The power charge is for the maximum electricity capacity you contract with the power company. You have to pay this even if you don’t use a single kilowatt, so choosing the right potencia when signing the contract is crucial. If it’s too high, you’re wasting money; if it’s too low, you’ll frequently trip the circuit breaker. The consumption charge is even more complicated, as most tariffs are now time-of-use, divided into three periods:
- Punta (Peak): The most expensive period, typically weekday mornings and evenings.
- Llano (Flat): Moderately priced.
- Valle (Off-Peak): The cheapest period, usually from midnight to 8 AM, as well as all day on weekends and public holidays.
So, if you want to save money, it’s best to run high-consumption appliances like the washing machine and dishwasher during the Valle period.

Water Bill
The water bill is a bit simpler, but it’s also split into a fixed service fee and an actual consumption charge. The fixed fee varies by city and covers the maintenance of the water supply network. The consumption charge is calculated based on how many cubic meters of water you’ve used according to your meter. Overall, water is much cheaper than electricity, but be aware that in some regions, water bills are issued quarterly, so don’t be shocked if you receive a larger bill all at once.
To give you a clearer idea, I’ve created a simple estimation table based on a 90-square-meter apartment in a city like Madrid or Barcelona, with 2-3 occupants. This is just a rough estimate; the actual costs will depend on your personal habits and the company you’re contracted with.
| Item | Approx. Monthly Cost | Notes |
| Electricity | €20 | Fixed part, independent of consumption |
| Electricity | €35 - €70 | Depends on usage habits and season |
| Water | €8 | Fixed part |
| Water | €15 - €25 | Costs can be higher in the summer; read more on Spanish utility bills. |
| Total | €78 - €123 | Does not include other fees like waste collection |
So, a typical household’s monthly utility expenses generally range from €80 to €130. The electricity bill will noticeably increase when using air conditioning in the summer and electric heating in the winter. I hope my experience is helpful to you all! I also welcome fellow residents to share what your monthly utility bills are like and if you have any money-saving tips. Let’s exchange some ideas!
